drop wears away the stone - heard the refrain?Folk wisdom also applies to the question of the expediency of such a thing as a waterproofing of the floor under the screed.Protection of structures from the ravages of moisture and the relevance and importance for the lucky owners of their own homes and for residents of high-rise buildings: for the life of flooring, good-neighborly relations, but what's there - the health of relatives and friends is at stake!Let us consider in detail how it can be made waterproofing the floor in front of the screed.


Proper arrangement of waterproofing will help to avoid the unpleasant prospect of floodingneighbors below.Imagine that you have made an unfortunate misstep flow of water in the bathroom over the edge.If the moisture will go to overlap, it would soon tread on the ceiling

of the neighbors (similar trouble can happen without your direct participation: breaking liner on the toilet tank, the failure of the crane, the sudden failure of the hose washing machine can occur at any time when no one is home).Only the observance of the rules, you can protect the waterproofing screed floor home from the damaging effects of moisture: in moist warm environment perfectly spreads mold that not palatable and safe for the health of the household, in addition, wet screed, transferring moisture floor covering is able to destroy it from within.

Among the options arrangement waterproofing screed waterproofing stand out with natural and synthetic bitumen, various derivatives of compounds based on bitumen, as well as various materials based on polymeric resins and reactive components.

The main types of waterproofing materials

  1. lubricative.
  2. Powder.
  3. roll.
  4. Film.
  5. mastics.

use okleechnoy waterproofing ↑

is a multilayer coating of Fiber-glass, roofing, steklovoyloka, gidrobutila, waterproofing, etc.The process of waterproofing of this type is very time consuming: Careful surface finish, alignment (bumps should not exceed 2 mm), the primer emulsion of bitumen and pasting directly.What is important is monitoring compliance with the technology, in order to avoid mechanical damage to the coating.

technology capillary waterproofing ↑

technology capillary (or penetration) insulation involves the use of the composition of a mixture of Portland cement, silica or silica sand with a variety of chemically active elements.The composition is applied to a wet surface active ingredients react with the cement concrete to form a stable crystalline complex, dense fill any crack at the material surface.The strength index is increased by 20%.An important feature - in the case of cracking occurs spontaneous development of reagents and cover "heals."Crystal tumors tend to trap moisture, without impeding traffic.

coating film materials ↑

various thicknesses (from 0.2 to 2 mm) and content, film materials are made of PVC, synthetic rubber, polypropylene, cellulose acetate, with the use of various additives, prolonging the service life of materials, durable, flexible and durable.

additional reinforcement fiberglass and synthetic fibers can achieve a much greater strength waterproofing.
tightly with plastic film of appropriate size lay around the perimeter of the room.

Continuity of waterproofing material is required as required approach covering the walls.In such a case, a kind of "cup", which prevents the penetration of moisture.

waterproofing mastic floor in front of the screed ↑

mastic called adhesive composition not only interconnecting a variety of materials, but still able to cover the surface structuresto protect against damage.First

often used: a method of coating plates mastic asphalt in two layers, or using a waterproofing of roofing material, which is a construction paper, soaked in bitumen.The joints of roofing material sizing in the same molten bitumen.Created in such a way waterproofing layer is able to isolate the water.But bitumen coating has serious flaws - over time, cracks, coating loses tightness and waterproofing becomes ineffective.

Processing lubricative slabs different compositions (Mastic, multicomponent sealants, etc.) is simple in execution, but has poor resistance to mechanical damage and hydrostatic pressure.

Waterproofing floor under the screed is needed is a barrier to moisture, because the screed is laid flooring and humidity ties will lead to its gradualdestruction.

simplest known since Soviet times waterproofing method - impregnation of the base bitumen or bitumen-containing materials in most cases is not justified because of the relatively low lifetime.When choosing the best method of waterproofing the foundation of everything you remember about the effectiveness of a comprehensive approach.Examination of the object, the preparation of the technical solutions, selection of materials and execution of works shall be carried out only by competent professionals.
