The rapid growth of construction in the last 10 years (including an individual, with high demands for product quality) gave an unprecedented impetus to the production of building materials. Fierce competition and diversity the proposed solutions require the manufacturer to the ongoing transformation in an attempt to create an ideal waterproofing material. Great was the role of the notorious "know-how, which at one time was the waterproofing penetrating. Waterproofing the market today offers a wide range of materials – different species, subspecies, modifications, and brands. All modern materials can be divided by type or krovlifundamenty can be made on and a myriad of ways to classify this or that kind, but such a classification – too abstract an aid man standing before a particular choice. Identify several basic and most commonly used types of waterproofing: roller and bituminous materials are sent, bitumen-polymer and polyurethane mastic material in the sand-cement-based penetrating action. Each of these species distinguish its pluses and minuses. In each case the same material can be the best or the most irrational decision.
Comparative characteristics of waterproofing Materials (general) Features Roll and bituminous materials sent bitumen-polymer and polyurethane mastic material in the sand-cement-based penetrating. Manufacturability of difficulty process corners, ledges of walls, pipes and I / O, etc. Excellent Excellent elasticity of material (sediment, movement, cracks, expansion joints) Low elasticity (as roofs and foundations) high elasticity (as a roof, so and foundations) Hard (foundations) Average life of waterproofing material data 7-25 years, 7-25 years of life is the same "life" of concrete waterproof Average 4 MPa, 4 MPa 12 MPa Work at positive pressure (outer waterproofing) Yes Yes Yes Work under negative pressure (internal waterproofing) No No Yes If the damage is an area of waterproofing Water "detaches" all linen, if not promptly remove the damaged area Corrected locally – the damaged area.
