Want to waterproof the old house? Look here!

Waterproofing is a very important part of building construction, which can prevent water from infiltrating and protect the building structure from being damaged. This paper will introduce the methods and materials of waterproof construction to help you better understand the necessity of waterproof.

Laying flexible waterproof layer

Laying flexible waterproof layer is a common waterproof method. You can choose paint or coil to ensure that the moisture content of the base surface is less than 9%. Five days of intense heat and continuous sunny days are the best construction opportunities. Be sure to do a water storage experiment after completion!

An example of "one cloth and two clothes"

"One cloth and two coats" is a common waterproof method. You need to clean the base, paint it and dry it. Then spread glass fiber cloth and brush a layer of paint to fix it. The total thickness of waterproof coating should be at least 3 mm!

Waterproof film structure

Waterproof coiled material is a common waterproof method. After the base needs to be cleaned, brush glue on the back of the coil and base, stick it according to the baseline and roll it up. Finally, check the seam end.

Waterproof material recommendation

The choice of waterproof material is very important. Flexible mortar is suitable for wall and bottom surface, not for top surface; It is convenient to stick bricks directly after hard mortar coating! Polyurethane can be used indoors and outdoors, with super waterproof effect!

Understand the necessity of waterproofing

Waterproofing is a very important part of building construction, which can prevent water from infiltrating and protect the building structure from being damaged. Structural waterproofing uses special structural forms to block water channels, such as water stop and cavity structure. Mainly used in roof, underground, external wall and indoor of building construction. In addition, it is also used in municipal engineering, traffic engineering and water conservancy engineering. With the progress of building technology, the application field of waterproof materials will continue to expand!
