Waterproof material: the strong backing to protect buildings

In rainy season, humid air and groundwater may threaten the safety of buildings. At this point, waterproof materials come in handy. They are the strong backing to protect buildings and prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, moisture and steam in the air from invading buildings. This paper will introduce the types and main raw materials of waterproof materials in the market to help readers choose suitable waterproof materials and ensure the safety of buildings.

Waterproof parts

The parts of the building that need waterproof treatment are mainly roof, wall, ground and basement. These parts are the places where buildings are most vulnerable to rain and groundwater erosion.

Asphalt waterproof material

The main raw materials of asphalt waterproof materials are natural asphalt, petroleum asphalt and coal asphalt, and the asphalt felt and paper tire asphalt felt made of them have good cohesiveness, plasticity, water resistance, corrosion resistance and durability.

Rubber and plastic waterproof material

The main raw materials of rubber and plastic waterproof materials are chloroprene rubber, butyl rubber and ethylene propylene diene monomer rubber. The prepare elastic tire-free waterproof coiled material and waterproof membrane have that characteristic of high tensile strength, high elasticity and high elongation.

Cement waterproof material

Cement waterproof material mainly enhances the hydrophobicity and impermeability of cement mortar and concrete by adding additives such as waterproof agent, air entraining agent and expansion agent into cement.

Metal waterproof material

Metal waterproof materials mainly include thin steel plate and galvanized steel plate. , which can be directly used as waterproof roof panels. Thin copper plate, thin aluminum plate and stainless steel plate can be made into water stop for deformation joints of buildings.
