(54) METHOD OF WATERPROOFING DEVICE

one

The invention relates to construction and can be used in the construction of residential, industrial buildings and underground structures.

Methods are known for a non-static waterproofing coating device by heating with burners of various types of the bottom coating layer of the web material 1 or the insulated base 2.

However, due to the difficulty of achieving uniform heating of the bonded surfaces, which is caused by the lack of heat flow stability, the presence of mineral dressing, exposure to atmospheric conditions, such methods of the device lead to local burns, non-gluing and leakage of the coating mass from the waterproofing coating. mechanical properties of bituminous materials.

The closest in technical essence to the present invention is a method for arranging a waterproofing coating comprising applying a primer and a bituminous roll material plasticized with a solvent followed by rolling. 3

A significant disadvantage of this method is the necessity of applying a volatile solvent to the plasticizable surface and using a solvent metering device. The uneven supply of the solvent, as well as its evaporation from the plasticized surface, reduce the quality of adhesion.

The purpose of the invention is to increase the adhesion of the substrate to the base in time.

This is achieved by the fact that in the method of a waterproofing coating device, including applying a primer layer of mastic to the base and placing a bituminous coiled material followed by rolling, after applying the primer layer of the mastic, hydrophilic material is applied to it in an amount of 30-80 g / m and incubated before rolling for 5-20 minutes, and on the primer layer .mastiki stack

cardboard or fiberglass, or polyurethane foam, or polystyrene foam.

Claims (3)

The drawing shows the sequence of the device for waterproofing the coating by the proposed method. A primer layer 2 of mastic is applied on the base 1, onto which the underlying layer 3 of hydrophilic roll material is placed, impregnated with a solvent in the amount of 30-80 g / m. Then the bituminous rolled waterproofing layer 4 is laid, kept for 5-20 minutes and rolled by roller or roller. When laying a hydrophilic roll material, it is pre-passed through a solvent impregnation bath. As the underlying hydrophilic material, foamed porous materials can be used, for example, polystyrene foam or polyurethane foam, glass materials, for example fiberglass or fiberglass, and cardboard, for example, asphamine. The use of hydrophilic materials of various porosities makes it possible to regulate the amount of solvent from 30 g to 80 g. The arrival rate is 1 m of plasticizable surface. White spirit, kerosene, gasoline, toluene, xylene, etc. can be used as a solvent. The type of solvent is selected depending on the network of applied bituminous materials and the design of the waterproofing coating. The exposure time (from 5 min to 20 min) is governed by the type of solvent and the properties of the roll waterproofing material. The use of a hydrophilic base layer eliminates the need for pre-application of the solvent on the plasticized surface, reduces labor costs, and allows the waterproofing layer to be laid immediately. The proposed method of waterproofing the coating improves the quality of gluing, since the plasticization of the coating layer of the rolled material pro3 2 proceeds in the finished coating both at the time of rolling and at a subsequent time, which significantly increases the durability of the coating. The proposed method makes it possible to arrange multi-layer coatings by repeating these operations with the difference that the hydrophilic material is laid between individual waterproofing layers. This method is also more economical in terms of solvent consumption, since it reduces its losses due to spreading and evaporation. Claims 1. A method of arranging a waterproofing coating, comprising applying a primer layer to a substrate and laying a bituminous web material followed by rolling, characterized in that hydrophilic material, impregnated with solvent in the amount of 30-80 g / m and incubated before rolling for 5-20 minutes. 2. A method according to claim 1, characterized in that a cardboard or fiberglass or polyurethane foam or polystyrene foam is placed on the primer layer of the mastic.
