General application principles of lapping roll roofing and waterproofing materials of Aquaizol trade mark

 

Laying technology

Introduction

By Amendment No 2 to DBN V.2.6 -14 -97 “Construction of buildings and structures. Roofing of buildings and structures” State Building Committee of Ukraine prohibited while projecting and equipment of the roofing mats the use of traditional roofing ruberoids on a cardboard base with a coating weight of izoxydised bitumen (RKP, RKB type and etc.), and ordered the use of modern roll roofing and waterproofing materials on not rotting basis with the cover weight of distilled bitumen, modified by styrene-butadiene- styrene rubber (SBS) or atactic polypropylene (APP).

On the Ukrainian market of roofing materials these materials both domestic and imported are classified as bitumen membranes.

This flow sheet applies to the building and repair of roofing using roll padding roofing and waterproofing materials of Aquaizol and Ruberit brands produced by “Aquaizol” Roofing materials plant.  Flow sheet is designed in accordance with the current Ukrainian legal and technical documentation for the design, construction and operation of buildings and structures of industrial, civil and agricultural purposes and it can be used by designing and construction organizations, as well as the operational services as an auxiliary material, taking into the account the specific features of roll roofing and waterproofing materials of Aquaizol and Ruberit brands.

When designing and using roofing materials of “Aquaizol” plant except this flow sheet it is necessary to be guided by the following documents:

  • • DSTU (NSOU) B V.2.7 -101 -2000 “Rolled roofing and waterproofing material. General specifications”;
  • • UNCR V.2.6. -14 -97 “Construction of buildings and structures. Roofing of buildings and structures” as amended. No 2;
  • • GOST 12.3.040-86 “Roofing and waterproofing works. Safety Requirements”;
  • • SNIP (CNR) 111-4-80 “Safety while construction”;
  • • PPB -95- 86 “Fire safety rules during the construction works”.

Before laying the material, the surface of the roof must be completely leveled and cleared. In the case of the old roof mat, it should be removed or repaired. If the laying is done on concrete or covering, before laying the roofing material it should be treated with the primer solution.

Since the solution has a low viscosity, it penetrates through the pores of the surface and binds dust which usually remains after cleaning.

This preparation ensures optimal adhesion of the material with the base. After the primer drying it is possible to lay the material using a gas or oil burner. Before you start laying the material you should make its fitting by its unwinding. If necessary, you should carry out the adjustment, using roofing knife. Further, the material must be twisted to roll back.

Gradually warming the lower covering (sticking) layer of the padding roll material with the simultaneous heating of the base (or the surface of the previously glued insulating layer), the roll is rolled and tightly pressed to the ground. 

You should remember that the excessive heat can damage the material, so it is recommended to apply the burner nozzles of different capacities, depending on the ambient temperature and the thickness of the material. Rolled material should be laid in overlap. Side overlaps should have the width of 8 cm, end ones - 10 cm to 15 cm. For making the side overlaps there is the edge without dressing along the edge of the whole material with the dressing compound with the width of 8 cm. For the implementation of end overlaps you will need to remove the dressing compound in the estimated area by warming that area with the burner. After the main laying of the material it is recommended to make the repeated heating of seams to make sure of their tightness.

2. Requirements for used materials 

2.1. Main characteristics and recommendations on selection of bitumen-polymer roofing and waterproofing materials of Aquaizol and Ruberit. While choosing the material for construction or repair of the roll roofing the customer is usually guided by economic considerations, i.e. strives to choose the cheaper materials, often with the detriment of quality and reliability of the roof mat.

The nomenclature of roofing and waterproofing materials produced by the Plant differs:

  • • by the type of the reinforcing basis, fiberglass or polyester;
  • • by the presence of the protective dressing (materials for the upper layer), or its absence (materials for the underlayment and waterproofing);
  • • by type of protective dressing, shale or granite;
  • • by the thickness of the coating weight (provided for reference) - a figure in brand name of the material without dressing and the figure in the brand name of the material - 1 for materials with dressing;
  • • Bythe type of modifier of the coating mass APP for Aquaizol materials.

SBS for Aquaizol materials and Aquaizol Waterproofing materials, Plastomers for Ruberit and Ruberit ECO materials.

Type of the modifier defines the extremely low temperature at which the normal laying and storage of material on the roof is possible while maintaining the elasticity on unwinding the rolls, as well as the extremely high temperature at which the material retains its physical and mechanical properties.

SBS- modified Aquaizol materials allow laying at ambient temperature up to -20°C and retain the physical and mechanical properties when heated to +100°С.

APP- modified Aquaizol materials (with dressing) permit the laying at ambient temperature to -10°C and retain the physical and mechanical properties when heated to 115 °C, and the materials without dressing when heated to +90°С.

Ruberit materials (with dressing) permit the laying at temperatures up to -5°C and keep the physical and mechanical properties when heated to  +100°С.

Ruberit materials (without dressing) allow laying at -5°C, and retain mechanical properties when heated to +90°С.

Ruberit ECO materials (with dressing compound) allow laying at temperatures up to 0 °C, and retain mechanical properties when heated to +90 °C.

Ruberit ECO materials (without dressing compound) allow laying at temperatures up to 0 °C, and retain mechanical properties when heated to +85 °C.

Glass-reinforced materials are usually used on flat roofs or roofs with a slope of not more than 4%, as the fiberglass is not elastic and on deformation or displacement of structures such material can crack in the direction of these deformations.

Reinforced polyester materials are used on the roofs of industrial buildings with arched trusses, the presence of flagons joining (“fractures” of the roof), the vibrations from the crane loads and operation of the process equipment.
It is not recommended to use the materials with granite dressing on roofs with a slope of more than 4%, as such dressing is less resistant to washout than the shale one. If the choice was right the warranty for the materials with granite dressing is 10 years.

When construction of a new roof it is necessary to perform the priming of the covering. Normative set of materials: - underlay 2.5, upper layer 4,0-P.

When constructing the roofs without removing the old roof mat it is allowed to use materials - 3,5-P.

••• – temperature and contraction joints are performed on end seams in the bearings.

3.2. When covering buildings with metal profiled decking and insulation material made of flammable and non-flammable materials the filling of the void edges of decking should be made with the fireproof materials for a distance of 250 mm from the  abutment to walls, expansion joints, walls lamps and sides roof ridge or roof flagons.

3.3. At areas of joining of roofs to walls, mines, and other structural elements there should be performed the fillets ensuring the smooth conjugation of intersecting planes.

3.4. In coverings there should be made the temperature-shrinkage seams with the width of 5-10 mm. The size of the cards of the cement-sand mortar should not exceed 6x6 m and of asphalt concrete 3x3 m. Joints should be positioned over the end seams of bearing plates and temperature- shrinkage joints in a monolithic insulation.

3.5. All surfaces of the concrete foundation, covering and concrete-sand mortar should be thoroughly dried, the dust removed, processed with primer. As a primer (primer) you should use anionic bitumen emulsion, ready bitumen primers with volatile solvents or the solution of tight fusible bitumen in kerosene according to1:3 (see § 2.2.). The primer is applied on the surface with the help of a brush, roller or spray. The dried out base is ready to start the construction.

4. Requirements to the insulating layers

4.1. The design of the roof mat depends on the slope and the type of coverage (see Fig. 1). In the new coating or its reconstruction (while overhaul repair with replacement of insulation) the roofing mat is made of two layers of Aquaizol, and the materials with the coarse dressing are used for the top layer. On the operating objects (roof terraces) the waterproofing is made of two layers of Aquaizol with protective film on both sides and reinforcement base of polyester. Note: it is possible to install one waterproofing system into a single layer on the roofs with low degree of responsibility.

4.2. When repairing the existing (old) without replacing the roofing insulation the roofing carpet should be made of two layers of Aquaizol or RUBERIT mark. In this case the desirability of insulation keeping installed can be determined by the detailed examination of the enclosing cover (if necessary with sampling to determine their status, including insulation humidity). Note: the repair of the roof mat can be made of one layer of Aquaizol or RUBERIT basis with the reinforcing glass fiber or polyester, depending on the state of the “old” roof, which is determined during its examination.

4.3. When construction the top layer of the roof mat you can combine the use of materials with reinforcing basis as polyester and glass fleece. At the same time the material on the fiberglass can be used only on flat areas that do not contain joints and precluding the possibility of shifting the framework.

4.4. When choosing Aquaizol brand depending on bitumen binder modifier it should be noted that the range of thermal stability of SBS- modified materials in comparison with the APP- modified ones is shifted toward lower temperatures. Roofing in winter should be done with the use of SBS- modified materials. APP- modified materials should be used on roofs (roofs areas) with slopes of more than 15 % at increased sunlight.

4.5. In places of height differences of roofs, insulation layers contiguity to the parapet, walls, sides of lanterns, in places of pipes crossing and others provide additional insulation layers of the same materials of which basic insulating layers are performed.

4.6. In connection with the requirements of paragraphs 2.18a, 2.18b, 2.18c, and 2.18d, 2.18e Volume 1, Sec. 2 the subparagraph “Projection of roofing mat” (according to the text rev. № 2 to DBN B.2.6 -14 -97), the number of layers and Aquaizol material grade is recommended for use in accordance with Table 3.

5. Construction of roofing. Technology, organization, constructive solutions

5.1. Preparation and checking

5.1.1. Before the start of roofing you have to made and accept: all construction and installation works, including pasting of seams (joints) between concrete slabs, installation of drain funnels, compensator of the deformed seams, pipes (or glasses) to skip the engineering equipment, anchor bolts, antisepticised wooden bars (or racks) to fix the insulation layers and protective flashings; steam insulation layers, leveling covers. On cover of the buildings with metal profiled decking insulation material made of flammable and non-flammable materials the voids of decking edges in areas of contiguity of the flooring to walls, expansion joints, lantern sides, as well as on each side of the roof ridge and flagon shall be filled with non-combustible materials on the length of 250 mm. Following the implementation of these works you should carry out the verification of slopes and smoothness of the basis for the roof under all surfaces, including the eaves of roofs.

5.1.2. Test works should include:

  • - Compliance with the project slopes of the watershed and other higher elevations of the roof pitch, to the lowest - drain funnels. To do this, you should set the level between the watershed and drain funnel and to determine marks using racks. The deviations are determined by the ratio of excess funnels marks over the points in the watershed to the distance between the measured points. If you find that base slopes or anti slopes (reverse slopes) are less than projecting one, you need to fix the cover bringing all marks to the project values;
  • - Check of the evenness across the ground surface produced by pulling the cord between the points and the lowest point of the watershed near the funnel, or three-meter rack applied to the surface of the cover along and across the slope; while the space between the surface bottom and the rack shall not exceed 5mm.

5.2. Construction of the insulating layers

5.2.1. The construction of the roof mat shall be performed in the following process steps:

  • - Pasting funnels of the internal gutters with the additional layer;
  • - Pasting flagons and eaves of roofs with the additional layer;
  • - Gluing of layers of the main roof mat;
  • - Pasting joining to vertical structures with the additional layers.

Number of layers and Aquaizol product are selected according to Table 3 p. 4.

Fig. 1. General constructive solutions of roof mat

General constructive solutions of roof mat Binding elements:

  • 1 - bearing elements (roof slabs, profiled sheeting);
  • 3 - vapour barrier;
  • 6 - insulating layer;
  • 8 - ventilation (desiccant) system –the air space in combination with air holes and channels;
  • 9 - roofing mat;
  • 10,11,12 - protective layers.

Additional elements:

  • 2 - leveling layer;
  • 4 - separating layers (“slip” layers);
  • 5 –slopes forming layer;
  • 7 - leveling cover.

5.2.2. Adhering Aquaizol is performed by heating (melting) of coating layer with burners that operate on LPG propane - butane or liquid fuel.

Processing methods of adhering Aquaizol are performed in the following sequence:

  • - On the prepared base you should roll 5-7 rolls in 2 rows in order to clarify the direction and overlap, then the material should be rolled back to the roll (on a significant cooling in winter, these operations are performed under the light hand torch heating of the outer surface of the roll).
  • - First you should stick the base to the end of the roll, heating the cover material and base with the hand torch. The main roll is adhered while a gradual roll sheeting, pressing it firmly against the base. Simultaneously you should produce seal overlaps. Roll stitching in overlaps is performed with the roller.

5.2.3. To glue the roll the roofer lights the burner and makes the bottom surface of the roll to melt, holding a burner at a distance of 10-20 cm from the roll. During this action you should be very careful. Excessive heating is unacceptable as it can result in burnout, melting of the coating layer on the front side of the roll.

You should be especially careful and follow the synchronicity of coating layer melting and rolling out the roll. The speed of movement is determined by the time required for coating layer of the adhesive roll to start melting that is evaluated according to the beginning of the formation of the bead of molten mastic.

You should not allow the leakage of mastic out of the roll more than 5 mm. More leaking evidences the material overheating and loss of quality of mastic (combustion and evaporation of light oil).

Fig. 2. Installation of the rainwater funnel

Installation of the rainwater funnel

  • 1 - precast concrete covering slab;
  • 2 - vapour barrier (estimated);
  • 3 - insulation;
  • 4 - leveling screed;
  • 5 - the main roofing mat;
  • 6 - an extra layer of roof mat
  • 7 - coarse dressing of the top layer of the padding roll material;
  • 8 - rainwater funnel cap;
  • 9 - lightweight concrete of leveling layer of the flagon;
  • 10 - rainwater bowl;
  • 11 - Seal.

The sign of normal gluing is the absence of blackening and bubbles on the upper side of the bonded roll.

5.2.4. Adhering the roof mat it is necessary to comply with the following value of overlap depending on the roof slope: the slope up to 5% - the overlap should be in all layers of not less than 100 mm in length and width of the panels; with a slope of more than 5 % - in the lower layers the overlap should be not less than 70 mm, and in the upper layer - not less than 100 mm.

5.2.5. For sheeting the roll it is possible to use the unwinding device having a T-shape with dimensions of 1000 mm at the shoulders, made of a metal tube with a diameter of not less than 15 mm.

The spindle of the unwinding device is fixed in the inner hole of the roll and put the fork on the spindle pins.

5.2.6. Funnels of the internal gutters should be installed according to the project in lower places with fastening them to the building. In places of internal drainage funnels passes through the roof the layers of the primary and secondary roof mat should enter the water intake bowl the mounting flange of which is attracted to the funnel bowl with nuts and the bowl of the funnel is attached to the cover plates by clamps with the rubber seals (Fig. 2). 5.2.7. It is necessary to start the interior lining of the funnels drains after cleaning the base of the funnel of debris and dust and, if necessary, dry. 5.2.8. The fiberglass for pasting the funnels is prepared in advance in form of gussets 1x1 m. Having laid the prepared material on the roof funnel in the centre of the funnel the roofer makes the cruciform cut and then sticks the gusset on the water intake bowl with the bitumen- polymer mastic.

5.2.9. Flagons in roofs with a slope of 2.5 % or more should be pasted with two additional layers. Pasting of the additional layers is carried out in the direction of the funnel to the watershed with the separate cloth without dressing compound which should be padded on the surface of the pitch for 750 mm (from the deflection line). The surface of the cloth should be initially tried on the place, and then one half of the cloth is folded along the longitudinal axis of the flagon, and is adhered tightly to the substrate with the help of the burner. Following the first half of the cloth in the same manner you should paste the second half (Fig. 4).

The roof apex (with a slope >3%) shall be reinforced with two additional layers of roofing material on the width of 150-250 mm on each side (Fig. 3) from the longitudinal axis of the ridge.

  • 6 – pasting of seams in areas of overlap;
  • 7 - the top layer of the roof mat.

On the prepared base for the roofing mat (according to this decision the basis is not covered by the primer) you should roll out the material along the line of the watershed and fix it with screws, screwed into the anchors. Under the head of the screws you should enclose the washers. Then fix the cloth along the line of the watershed with screws on both sides. Then roll out the second roll, try on it to the first so as to ensure a uniform overlap of edge of the second roll on first not less than 100 mm, use a gas burner to melt the second edge and past it to the edge with screws to the first one.

Thereafter, the free edge of the second roll should be fixed by dowels, screws and washers. The top (second) layer of the material is pasted in this way so that it overlaps the longitudinal and transverse seams of the underlying layer.

5.2.19. Roof construction of Aquaizol and Ruberit should perform the roofers’ team consisting of 4 people.

To calculate the labor and material consumption data you should use p. 5.4.

All figures are provided for reference.

5.2.20. The supply of materials to the work site is performed using the construction and installation of cranes, hoists or other mechanisms (roof cranes). Conveying of the material along the division or section is made using a trolley. The storage of materials in warehouse is carried out in containers or pallets racks. The material is stored vertically.

5.3. Restore the damaged roof mat

5.3.1. Repair of the existing roofing:

  • - The existing roof covering should be cleaned of the residues of the destroyed layers of dust and other contaminants;
  • - The places of mechanical damage and cracks should be sealed with bitumastic or welded with the gas burner;
  • - Upheavals on the roof covering are cut crosswise by the roofing knife and folded to the side, the opened surfaces of the roofing should be  thoroughly cleaned and dried, then pasted with the roof bitumastic on their place;
  • - Repair of the damaged sections of roofing can be done by fire heating of the existing layers of roofing ruberoid and brewing the defects in the presence in the outer layer of not less than 2 kg/sq.m of bitumen binder. For this the damaged area should be warmed up on the perimeter, and after melting of the bitumen binder the roofing ruberoids should be smoothed to the damaged place, gradually filling the damaged area with the molten mass.

5.3.2. Drying of basis:

To permit the moisture under the existing roof covering to go out it is recommended to punch the roof mat for 4-6 holes per 1 sq.m, up to the roof basis.

5.3.3. Heat insulation drying:

If there is some moisture in the insulation you should mount the roof fans (wind vanes) directly on the base to provide the ventilation of insulation layer, for this it is necessary to cut the holes in the existing roofing and insulation material with a diameter slightly larger the diameter of the vane inlet.

5.3.4. Priming of the existing roofing:

You should apply a thin layer of bitumen primer on a dry, clean and renovated base with a brush or roller, it is necessary to improve the adhesion of the new coating to the existing roof covering.

Consumption: about 0.2 - 0.6 kg per 1 sq.m of roof.

5.3.5. Ventilated layer construction:

- the perforated roofing ruberoid designed for pressure equalization and preventing of blisters under the new roof covering should be laid on the base dried after priming. The laying of the perforated roofing material should be made without pasting, with overlaps of 2-3 cm; 

- perforated roofing ruberoid is laid departing from the edges and overhangs of the roof at a distance of 50 cm;

- perforated roofing ruberoid is not placed in the gutters.

5.3.6. Installation of the roof fans (vanes):

- Roofing fans are mounted on the roof on the perforated layer of roofing ruberoid;

- Roof fans are installed at the top of the roof, at the rate of 1 pc. per 40-60 sq.m of roof surface (see Figure 12);
