Bitumen materials are road, roofing and building. Due to the simplicity of use and low cost of bitumen, it is widely used in waterproofing work. This makes him attractive for private construction. Bitumen consists of three main components. Resins (18 — 48%) and mineral oils (40 — 65%) give it plasticity, and asphalons (13 — 30%) — hardness. To create a waterproofing layer, the most suitable brand 70/30 is the most suitable. Its softening temperature is 70 — 72 degrees. Such bitumen can be distinguished by the fact that, with mechanical exposure (impact), it beats on pieces, without forming fragments. One of the advantages of this bitumen — it sticks well to the surfaces of any material (high adhesion).
