1 AREA OF USE

Installation of a soft roof made of rolled fused waterproofing roofing material
(Stekloizol , Technoelast , Bikrost)

1 area of ​​use

The technological map has been developed for the installation of soft roofing from fused rolled materials Stekloizol, Technoelast, Bikrost and their analogues.

The rolled material consists of a cardboard, fiberglass or polyester base, coated on the outside with a layer of bitumen-polymer binder, and on the inside with a built-up layer of bitumen mastic, which allows it to be used for installing one-, two- and three-layer roofs without adhesive mastics. The bases for a built-up roof can be the surfaces of reinforced concrete slabs or thermal insulation, as well as prefabricated or monolithic screeds. For the installation of the lower and upper layers, roll materials of various modifications are provided. The type of roll material must correspond to the project.

The work covered by the technological map includes:

• surface preparation;
• vapor barrier device;
• installation of a thermal insulation layer;
• screed device;
• installation of a fused roof made of fused rolled material;
• installation of water intake funnels and junctions.

The construction of a soft roof made of fused rolled materials is carried out in accordance with the requirements of federal and departmental regulatory documents, including:

• SanPiN 2.2.3.1384-2003. Ministry of Health of the Russian Federation. Hygienic requirements

  to the organization of construction production and construction work.

Materials are supplied to the roof using a Pioneer cantilever-beam crane or a KOR crane.

Work is performed in one shift in summer conditions during daylight hours.

2. Organization and technology of work execution

Before the construction of the base and roof covering from fused rolled waterproofing material begins, the following organizational and preparatory measures and work must be completed:

• work on the installation of load-bearing structures and parapets has been completed and accepted

  roofs, grouting of seams between prefabricated reinforced concrete

  designs;

• details of expansion joints are made;
• embedded parts installed;
• holes were made to allow communications to pass through;
• sections of stone structures were plastered to the height of gluing

  roofing carpet;

• a work permit for high-risk work has been issued;
• tools, devices, equipment have been prepared;
• materials and products are delivered to the workplace;
• familiarize performers with the technology and organization of work.

The work front in the plan is divided into sections, and sections into plots. Work on the plot is carried out within one day.

The construction of the base and roof covering made of fused rolled material is carried out in the following order:

• installation of drainage funnels;
• leveling screed device;
• vapor barrier device;
• laying a thermal insulation layer;
• the roof is installed layer by layer using a welded coating

  waterproofing roofing material.

The cement-sand screed is installed with a thickness of at least 30 mm in the following order: install guides from pipes with a pitch of 1.5...2.0 m; lay the mortar mixture in strips, leveling and smoothing it according to the guides in 2 stages: first, the odd strips, and after the mortar has hardened in them, the even strips.

The mortar mixture is supplied using mortar pumps through pipes or using trolleys on pneumatic wheels.

Expansion joints are installed in the screed at intervals of 4 meters. In places where the rolled carpet adjoins walls, parapets, shafts and risers, fillets with a radius of at least 100 mm are arranged.

After gaining strength, the cement-sand screed is primed with a cold bitumen primer primer. The primer is applied with brushes, a roller, and if the roof area is more than 200 square meters. - using a spray gun.

When installing a leveling screed made of asphalt concrete, it is laid in strips up to 2 m wide and compacted with a roller weighing at least 50 kg.

Before the installation of the roof covering begins, it is necessary to check the quality of the base and compliance with the slopes, check the completeness of other construction and installation work on the roof, check the availability and completeness of materials for the roof installation, prepare machines and equipment for transport and roofing work, prepare the construction site and workers places on labor protection and fire safety issues, check the availability and readiness of tools and devices.

When installing a vapor barrier, the following processes and operations are possible: cutting off mounting loops; removal of construction waste; alignment of defective areas on load-bearing structures; surface dust removal; drying wet areas; supply of vapor barrier materials to the work site.

Mounting loops protruding from the plane of the slabs are cut off with an electric grinder or gas cutter.

Dust removal of the surface is carried out with brushes, brooms, an industrial vacuum cleaner or a jet of compressed air.

Leveling the surface of the slabs, as well as sealing joints, chips, potholes and cavities larger than 5 mm, is carried out using cement-sand mortar grade 50.

Drying of wet areas of the base occurs naturally (solar radiation).

The surface is primed using a primer.

The vapor barrier is laid dry (the moisture content of cement-sand screeds should not exceed 4% by weight, and of asphalt concrete screeds - 2.5%.). The joints are taped with tape to seal the joints. The layout of the panels is carried out starting from low areas and drainage funnels.

The installation of bulk thermal insulation made of expanded clay is carried out in the following order: mark the top of the thermal insulation on parapets and lighthouse posts; install lighthouse slats in increments of 3...4 m and check their position; prepare and serve materials; distribute bulk material into strips with compaction.

1 - parapet; 2 - rail; 3 - expanded clay; 4 - lighthouse strip; 5 - solution or column.

Installation of soft built-up roll waterproofing roofing on corrugated sheets

The corrugated sheeting is laid in such a way that both transverse and longitudinal slopes to the drainage funnels are simultaneously created.

Before laying the vapor barrier layer, you must:

• complete all types of construction work on the surface;
• install shaped steel elements at the junction of the corrugated sheets

  to parapets and walls of lanterns;

• install metal compensators at the device locations

  expansion joints.

The vapor barrier material must be glued to all vertical surfaces, extending it 30-50 mm above the thermal insulation layer.

When laying vapor barrier material on a corrugated sheet, the material is rolled out along the edges of the corrugated sheet. The lateral overlaps of the vapor barrier material should be 80-100 mm and always located on the edges of the corrugated sheet.

Laying thermal insulation on corrugated sheets under roofing waterproofing rolls
deposited material

Thermal insulation boards should be laid on a profiled sheet by positioning the long side of the insulation boards perpendicular to the direction of the corrugated board ribs.

When installing thermal insulation from two or more layers of slab insulation, place the seams between the slabs “staggered”, ensuring a tight fit of the slabs to each other. Seams between insulation boards of more than 5 mm must be filled with heat-insulating material.

Filling the voids of the corrugated board ribs with bulk insulation on the roof is not allowed.

It is easiest to start laying insulation from the corner of the roof. When laying, the thermal insulation boards are additionally cut so that the joints of the slabs of the 1st and 2nd layers do not coincide. This cutting of insulation is suitable for insulation with dimensions of 500x1000 mm or 600x1200 mm.

Roofers first lay the bottom layer of high-hardness mineral wool slabs on the finished vapor barrier layer, and then the top layer of hard mineral wool slabs. Next, using an electric screwdriver, install plastic anchor buttons. The roofer puts a button on the working tip, pushes it into the layer of thermal insulation with a light blow and at the same time turns on the screwdriver, which he uses to tighten the self-tapping screw.

When fastening Tekhnoruf mineral wool slabs to a corrugated sheet, the slab or part of the slab must be attached to the base with at least one fastening element. To fix the mineral wool insulation to the base through the first layer of roofing carpet, use a plastic cup with a diameter of 50 mm with spikes (Fig. 2); to attach only the insulation to the corrugated sheet, use a cup with a diameter of 75 mm (Fig. 2).

Insulation boards can be glued together hot roofing mastic TechnoNIKOL No. 41. The gluing must be uniform and amount to at least 30% of the area of ​​the surfaces to be bonded.

Tekhnoruf mineral insulation that gets wet during installation must be removed or replaced with dry material.

The insulating roofer uses a trolley to bring it to the workplace and then manually lays out the slabs over the area, starting from the top point. First, on an area of ​​10 - 20 m², the slabs are laid in the bottom layer, and then in the top.

The creation of longitudinal slopes to drainage funnels in gutters is carried out using Technoruf V60 slope(with a two-layer thermal insulation system, installation is carried out on the first (top) layer of material), Tekhnoruf B60 fillet(designed to ensure a smooth transition of waterproofing material from the horizontal plane of the roof to the vertical plane of the parapet), Technoruf N30 wedge (to create a slope on the roof of 1.7% and 4.2%,)

If the project provides for the creation of slopes to the water intake funnels, then before laying the slabs, bulk material is spread in a layer of variable thickness. The installation of a heat-insulating layer of mineral wool slabs is carried out after leveling the expanded clay. The slabs are laid close to each other in the direction from bottom to top. The insulation layer is laid in such a way as to ensure reliable drainage and prevent water stagnation. Hydrophobized aerated concrete slabs are laid dry on a vapor barrier.

Panels of rolled roofing fused waterproofing material are fused by liquefying the covering layer onto a screed, concrete surface, insulation or other underlying layer.

When installing a roll roof, processes and operations are performed in the following sequence:

• preparation of roofing materials, mastics, compositions and parts;
• installation of eaves overhangs;
• supply of roofing waterproofing weld-on materials, mastics;
• base primer;
• gluing additional layers of rolled roofing

  waterproofing material in places where drainage funnels are installed,

  valleys;

• gluing rolled waterproofing material at the junction points

  waterproofing roofing layer to walls, shafts, parapets, pipes;

  quality control of processes performed.

The installation of roll roofing on grips is carried out from low to high areas. Rolling out and gluing of panels of roofing waterproofing materials is carried out in the direction opposite to the water flow.

The gluing of panels of roofing waterproofing material is carried out as follows:

After preparing the base and marking the position of the first panel, roll out the roll along the marking line, then roll it up at one end by 1.5...2 m, light the gas burner and direct the flame to the mastic layer of the rolled roofing waterproofing material. The roofer holds the burner glass at a distance of 100...200 mm from the roll and melts the mastic layer by pendulum movements of the burner along the roll. After the formation of a bead of mastic layer flowing down from the underside of the roll, the roofer rolls out the roll, smoothes it and presses the panel to the base. The work proceeds cyclically: melting the mastic on the panel area, rolling it out. The gluing speed of the roll is determined visually as the bonding bead is formed during fusing.

Scheme for laying rolled roofing waterproofing material

1,2 - positions of the first panel;

2 - groove axis; 3-gas burner; 4 - folded part of the panel; 6 - panel; 7 - stack of rolls; 9 - cylinder.

The procedure for constructing a rolled carpet from fused materials is as follows. Mark the position of the first strip of material

Installation of rolled roofing waterproofing carpet in places installation of water inlets performed in the following order. Before gluing layers of the main roof covering, check the marks of the completed screed or laid rigid insulation. Under the collar of the water inlet funnel, two layers of underlying rolled waterproofing material are additionally glued.

Requirements for quality and acceptance of work

When installing a roof made of fused rolled material, production quality control is carried out, which includes: incoming control of materials and products; operational control of roofing work, as well as acceptance control of completed work. At all stages of work, inspection control is carried out by representatives of the customer’s technical supervision.

The manufacturer must accompany each batch of products with a quality document, which must indicate: - name and address of the manufacturer; number and date of issue of the document; batch number; name and brands of structures; date of manufacture of structures; designation of technical conditions.

A document on the quality of products supplied to the consumer must be signed by an employee responsible for technical control of the manufacturer.

Incoming quality control of materials consists of checking by external inspection their compliance with GOSTs, technical specifications, project requirements, passports, certificates confirming the quality of their manufacture, completeness and compliance with their working drawings. Incoming inspection is performed by line personnel upon receipt of materials and products at the construction site. The shape and main dimensions of the products must correspond to those specified in the project.

All products are subject to external inspection in order to detect obvious deviations in geometric dimensions from the design. Dimensions and geometric shape are checked selectively by single-stage inspection.

The construction of a roof made of fused rolled materials is permitted only after acceptance of the base elements. The operational quality control scheme is shown in the table.
