So far there exist a great number of ways and materials for waterproofing roof coatings and any other structural units. According to the constitution method the following water proofing is distinguished:

  • rigid;
  • membrane;
  • painting;
  • surface;
  • mastic;
  • treating;
  • injectable;
  • superdiffusive and diffusive membranes;
  • polymer films (membranes).

Besides there exist a lot of many other waterproofing methods as well as materials. But we will consider only roof waterproofing materials.

Roof waterproofing materials types

Rigid roof waterproofing is a profiled metal or polymer material coating in the form of sheets that are attached to the bottom in rigid attachment with screws, nails, anchors, sealing and other fastenings.

Membrane water proofing is conducted with bitum and other materials based on it. In general such water proofing is conducted in several layers each of which is several centimeters thick, depending of the bottom condition.

Painting roof waterproofing assumes liquid solution brushing, roller, or other tool coating to an insulated surface of different mastics.

Mastics can be produced on the base of synthetic polymer materials with salamander wool, talcum powder addition. The mastic is applied in several layers, total number is about 4 layers, 3-5 mm thick each.

Surface water proofing is conducted by sticking waterproofing roll materials with prepared roof base. Roof waterproofing materials can be:

  • Bitum roll materials;
  • bitum polymer;
  • polymer;
  • bitum-rubber coatings.

The surface roof waterproofing is conducted on several layers. The number of layers is introduced on the blueprint stage. In general 2-3 layer roll material coatings sticking to waterproof glues or mastics are used for roof waterproofing.

Mastic or liquid roof waterproofing is a polymer membrane without joints and cuts. This is an undivided coating that provides the most reliable waterproofing of all the roof elements that are under it. The membrane consists of a glass fabric or glass cloth reinforcing layer, bedded with mastic on bitum, bitum-polymer, thiocol base and other components.

Treating roof waterproofing is conducted on roofs, covered with expanded material, such as asbestos-cement boards, concrete slabs and others.

They also use membranes and films for roof waterproofing that are subdivided into diffusive and superdiffusive ones. They are distinguished by the fact that the first ones can show themselves off really well only with an upper or lower ventilated split. They are produced on the polyvinyl base. These are polyethylene films, synthetic gum (artificial rubber), polypropylene film and so on.
