Secondary waterproofing is to better ensure the durability and waterproof effect of buildings in stormy weather. This work is generally treated with specific materials. The following are several common secondary waterproofing methods:

Brush waterproof

Brush waterproofing is the application of liquid waterproof materials to building surfaces, also known as coating waterproofing. Waterproof coating is easy to operate and has high strength and tensile strength. According to different needs, different types of waterproof materials such as organic and inorganic coatings can be used.

Coil waterproofing

The coiled material is usually made of polymer material, which is laid on the wall or roof, which can effectively interfere with water seepage and provide overall compression resistance. This method is suitable for different types of grass roots and weather conditions, and can resist the influence of sunlight radiation, acid and alkali erosion, infrared rays and ultraviolet rays.

Spray waterproofing

Waterproof by spraying is to spray waterproof materials evenly on the surface of buildings with special spraying equipment to form a firm and seamless waterproof film. This method can not only complete large-scale construction work quickly, but also have very good sound absorption effect.

The above are several common secondary waterproofing methods. Choose a waterproof method suitable for your own building structure and use the scene to ensure good results. However, the construction process requires professional skills, and it is strongly recommended that you choose an experienced regular waterproof company or studio for service.
