The horizontal waterproofing of the foundation

horizontal waterproofing of the foundation is done to prevent capillary suction of moisture from the soil.Even with high-quality waterproofing the basement walls is the likelihood of moisture through the base or damaged areas of the seal section.At the same time the foundation porous material absorbs water like a piece of sugar.It wets not only the foundation, but the walls of the ground floor.Freezing wet structures leading to their damage and cracks, and subsequent temperature changes the situation is aggravated.In addition, moisturizing foundation is responsible for the deterioration of the microclimate in the house, raising the humidity and the appearance of mold, mildew, swelling of wooden structures.All this can be avoided if timely perform a horizontal waterproofing of the foundation.

Forms horizontal waterproofing

Horizontal isolation can be performed:

• roll materials from a prepared base;
• impregnating and injecting.

waterproofing roll materials, kraftliner or pontoon method performed during the construction of the building, before the erection of walls.

impregnating waterproofing and injection can be performed both in the construction and during the operation of the building.

Okleechnaya horizontal waterproofing of the foundation

to perform a horizontal waterproofing of the foundation must be the device leveling screed.Most often it is made of cement-sand mortar with the addition of filler improves the water resistance of concrete.As the base material for a waterproofing material webs protrude on bitumen or a polymer-based high mechanical strength.

technology waterproofing:

1. foundation surface level using cement-sand screed with addition of additives that increase the resistance of concrete water penetration.
2. After drying screed foundation primer surface primed with an aqueous or bitumen base with a roller or brush.After that, give the primer to dry for a few hours and put a layer of mastic asphalt or polymer onto a horizontal surface of the foundation, paying particular attention to corners, joints and other design elements, where possible condensate stagnation.
3. for waterproofing roofing material and other roll materials, requiring the application of an adhesive layer paste to dry is not necessary - the first layer of roofing material is laid directly on mastic.If a lining hydraulic seals with the adhesive layer, the web material is adhered to the dried mastic, thoroughly proglazhivaya roller to remove air bubbles.
4. To apply a floating isolation needed propane burner: the roll is heated and slowly rolled over the surface, pressing it to the base.

5. some roll insulation is laid in two or three layers, thus it is necessary to make sure that the seams overlap the upper band.The width of the waterproofing should be such that it covers any contact with the foundation walls of the building, including the finishes and interior plaster.
6. for buildings with basement waterproofing horizontal operate under the sole foundation, slightly above the blind area, and in the place of the end cap.For buildings without a basement sufficiently seal the foundation of the walls.
   

   process of applying horizontal waterproofing on the foundation

Penetrating horizontal waterproofing of the foundation

penetrating surface waterproofing is carried out with the use of mortars with modifiers - active chemical compounds.When interacting with concrete, they crystallize and form a solid surface layer waterproof, resistant to aggressive chemicals and erosion.The process is relatively inexpensive and very effective, but requires preparation.

technology implementation penetrating surface waterproofing:

1. concrete surface is cleaned to a solid layer, remove dust, dirt, rust and paint, sealing residues.fat remnants are cleaned with a solution of hydrochloric acid.The prepared surface should be solid, have open pores, valves should be cleaned to bright metal.Joints, cracks and seams embroidered and trimmed.Slurry
2. mixed with a filler, water, and modifiers for instructions and allowed to mature.
3. concrete surface is moistened with water to saturation, but not waterlogged - it will improve the grip and allow the solution to penetrate more deeply into the material.Apply
4. mortar with a spatula and allowed to equalize to dry for several days, in this time, it is impossible to load.Made in this way significantly improves the waterproofing of concrete structures watertight, so it can be used both in the construction of new buildings as well as in the repair and renovation of existing buildings.
   

   process of applying penetrating (lubricative) waterproofing

Penetrating Sprayable waterproofing is done using special solutions on the basis of two-component polymer solutions.They have a low viscosity, thereby able to penetrate deeply into the concrete, the capillaries filling it, and after contact with the hardener to form a waterproof layer.The penetration waterproofing sprayed on the newly constructed structures is usually combined with the vertical waterproofing.

injectable basement waterproofing

for repairs of foundations used as an injection method based on the saturation of the porous concrete through a specially drilled hole.The penetration depth of up to half a meter, and on contact with moisture in the basement, injectable solutions swell, completely closing the pores and preventing the rising moisture from the ground.

technology implementation injection waterproofing:

1. basement walls from the outside or the inside is cleaned of contaminants and residues roll waterproofing.Calculate the required number of holes - holes, placing them at a distance, to form a continuous waterproof layer in the foundation.
2. drilled holes to a depth of a little more than the width of the foundation, placing them at a slight angle.The nozzle insert hole - Parker, serving for the supply and uniform distribution of the composite solution.
3. used for supplying low-pressure pumps (not more than 0.4 MPa), allowing low viscosity polymer gel mixed with a hardener immediately prior to its introduction into the body of concrete structures, thereby achieving a deep absorption prior to curing.
4. impregnation to produce a complete filling of holes, then Parkers removed and the openings sealed cement-sand mixture.

After curing the polymer composition of the swelling and interaction with the moisture content of the concrete, a waterproof layer is formed completely.

All types of horizontal waterproofing effective enough, but for maximum protection against the ingress of moisture into the structure of the building must be provided as a vertical hydraulic protection foundation.Thus basement waterproofing with their hands - it's not a difficult process.
