Waterproofing. Waterproofing solutions and materials

There are the following, the types of waterproofing: obmazochnuyu (painting), asphalt, covered with, or hard. Obmazochnaya Obmazochnaya waterproofing waterproofing - a continuous waterproof layer deposited on the surface of bitumen mastic thickness of about 0,5 cm Paint insulation - a thin layer of coloring composition (no more than 1 mm). The prepared surface layer of waterproofing applied by brush or spray. Such isolation is used to protect against capillary moisture bottoms of foundations. Composition of isolation: etinolevye paints, mixed with raspushennym asbestos and pigments, dyes, causing it to three layers: the first - with a brush, then spray. At obmazochnuyu (painting) Waterproofing deposited on the underground parts of buildings or structures, put clay castles of a thickness not exceeding 0,5 m from ground clay mixed with 2-3% (by volume) of oil or Degteva residues. Cast asphalt insulation Cast asphalt insulation - a continuous waterproof layer of asphalt masses about 1 cm thick is applied in hot form at a temperature of 160-180 ° C (cold in the form of emulsion pastes and pastes with admixture of 3-4% cement). Hot mastic waterproofing properties acquired after cooling, cold - after drying. Pasted laminated waterproofing waterproofing - a complete covering of the roll material, glued in several layers on insulated surfaces with special cements (Fig. 35). For Labels glassine, roofing, brizola apply bituminous mastics, which are selected depending on the temperature conditions during the stickers. Softening point of bitumen in order to avoid slipping rug should be higher than air temperature. Fig. 35. Okleechnaya waterproofing (dimensions in cm): a - multilayer insulation, b - a device for rolls of labels, and in - the groove for attaching an insulating mat, d, e, f, g, h, - Tools and Accessories: 1 - protective and leveling screeds; 2 - the cover layer 3 - nakryvka 4 - roll material, 5 - polkleyka 6 - Primer: 7 - insulated design, 8 - cell cup with mastic; 9 - elastic roller; 10 - waterproofing carpet, 11 - single, 12 - spatula-blade 13 - stroke: 14 - ladle spatula, 15 - Brush, 16 - the first, 17 - a second layer of label produced after drying primer. The first layer of mastic is applied about 1 cm thick, then rolled coil and fixed by attaching one end of the cloth. Waterproofing material adhesively bonded to the overlap of 10 cm, and the seams between the layers with sheets of regular shift with respect to each other by 1 / 3 the width of the cloth. Vertical surfaces, paste over the following way: rolls stick plots height 1,2-1,5 m, stickers are a bottom-up, smoothing and prikatyvaya rolls in the direction from the middle to the edges, edge rolls proshpaklevyvayut and smooth. The free ends of the horizontal rolls of carpet lead outside insulated surface, prevent injuries temporary protective structures, to label the vertical carpet is a protective device is removed. Freed ends of rolls clean of dirt and wrap them on the wall, adding mastic and compacting. Glued the carpet, arrange a protective wall of brick or concrete, as for insulation of the inner surfaces carefully paste rolls in the corners. Foundation waterproofing roll of carpet is a monolithic screed of cement-sand mortar (DM 50-100), or asphalt. Screed should have a thickness of laying the concrete for about two centimeters. Cement screeds primed viscous paste consistency, priming operates in the summer during solidification of the solution, it penetrates the cement layer, firmly grappling with it and protecting it from moisture needed for hydration. Waterproofing coating finish protective screed of cement-sand mortar (3 cm) or asphalt thickness of up to 5 cm bituminous mastics for gluing insulating materials are given in Table. 11. In conclusion - a few words about the used roll of waterproofing materials. Commonly used bitumen (asphalt, roofing felt) and Degteva (roofing only) materials. In recent years, a host of other waterproofing materials: waterproofing (biological stability of the material from asbestos paper impregnated with oil oxidized bitumen) Steklobit (the material of glass fiber base with the application of bitumen, rezinobitumnyh or bitumen-polymer substances; much more durable roofing or roofing material), folgoizol (aluminum foil, covered on both sides of bitumen-rubber stuff), rolled isolate and brizol (these materials have no basis and are made from a mixture of bitumen, rubber, asbestos, plasticizer and antiseptic), etc. The choice of waterproofing material is dictated by specific decisions, the presence of materials for sale and financial capabilities.
