Okleechnaya basement waterproofing

Okleechnaya basement waterproofing applied to protect against groundwater pressure hydrostatic force of more than 0.1 MPa.From surface waterproofing it features high mechanical strength and water resistance.Okleechnaya waterproofing is performed in a continuous mat consisting of several layers of web material joined together by adhesives and mastics and fixed on the base.

Installation of roll materials can be carried out in several ways:

• gluing using mastics and adhesives;
• pasting on adhesive layer;
• weld by heating bitumen or polymer layer deposited on the roll waterproofing.

Choice web material for waterproofing

to select the back-lining insulation is necessary to know the conditions of operation of the foundation, the soil type and moisture content.Roll materials can be used for horizontal and vertical waterproofing, with the choice of material is caused waterproofing appointment.The range has a roll waterproofing on a different basis and with different types of coatings that are distinguished mechanical strength, resistance to chemically aggressive liquids, resistance to underground radioactive gases, as well as efforts to different hydrostatic pressure of groundwater.

For horizontal waterproofing of the foundation slab used roll materials with high base strength, polymer or glass fiber based - slab foundation also serves as the floor of the ground floor, so the use of floating bitumen materials less suitable because of the smell and low plasticity.

recessed vertical waterproofing the basement with high pressure water and rocky ground is performed using a roll materials with abrasive grit - they are highly resistant to damage.

in radon release areas use waterproofing with a protective layer of foil, it protects against radiation cellar space and a basement.In areas of active growth of plants used roll materials with biosecurity, resistant to root penetration.

technology performance lining hydraulic seals

1. Preparing foundation for lining hydraulic seals comprises a number of stages.It is necessary to align the base, remove the tabs and trowel grout potholes, broken shells and place.Expansion joints further treated with sealant.The surface must be dry, remove traces of grease, paint, rust, deteriorate the adhesion.The faces, sharp edges, protruding rebar cut.Before laying the roll material surface is primed and dried over the primer layer is applied surface waterproofing and held it up to complete solidification.After preparation of the foundation is ready for pasting roll materials.

2. Materials with self-adhesive layer of glue to the prepared surface, tightly clutching and laminating them with a solid wide roller.The horizontal plane layout is selected so as to obtain a minimum number of joints.The vertical waterproofing is made from strips cut height of the foundation.Overlap adjacent strips - 10-15 mm, each subsequent layer is placed on the center strip of the previous seam, in a checkerboard pattern.Places glued joints further polymeric adhesive or mastic.The top layer of coating is also coated with insulation.

3. Pontoon roll materials different from the adhesive so that they are coated with a layer of bitumen mastic or polyethylene, which must be pre-heated to melt by a gas burner.This work is more convenient to carry out together, especially on vertical surfaces.A roll of adhesive is laid the foundation side and gradually heating, and roll pressed to the substrate.The edges can be further waterproofed with bitumen.

4. materials that require gluing, put a similar way, only with the prior application of adhesive.The number of layers should be at least two to prevent seepage of moisture, and at least three hydrostatic head of 0.1 MPa.

5. Okleechnaya insulation on vertical surfaces, especially on sites with heaving soils, protect the structure of brick, concrete, insulation.Without the protection of lining hydraulic seals can deform during shrinkage of the foundation, as well as during seasonal movements of soil.If
6. perform horizontal and vertical lining hydraulic seals, is necessary to maintain an overlap on the corners at least 30 cm. When waterproofing drainage device should be performed below its level so that the moisture running down the drain pipe.Drainage at a high level of groundwater is performed on the perimeter below the depth of laying the foundation.
7. backfill produce coarse sand - water easily passes through it and is collected in the drainage, thereby thrusting pressure on the waterproof coating is reduced and decreases swelling soil under the foundation base that extends the life of the building.
8. For additional protection from atmospheric moisture carry waterproofed otmostku: make dumping gravel on the perimeter of the building, poured concrete formwork with a slope from the walls, and after drying concrete formwork lining hydraulic seals operate with subsequent finishing high-strength cement or tile.Roll waterproofing with a stack of lap on the wall previously having equipped fillet.

lining hydraulic seals is widespread, both in the private as well as in high-rise construction.With the right choice of material and high quality of work performed its service life is 20 years or more, and for the timely repair and basement space of the ground floor is not threatened wetting and high humidity.Thermal insulation on the outside of the foundation can further protect the basement from the condensation of moisture.

Modern kind of roll waterproofing membrane films can be called with a protective coating studded.They have a double function: do not absorb moisture from the soil to the foundation and contribute to the withdrawal of the water vapor from the inside of the foundation.Moisture condenses on the outside of the cover and is discharged to the drain, and profiled polymer coating evenly distributes the pressure and prevents soil foundation deformation.
