Hefei Shuangjin is happy to answer your question: You want to find a good waterproofing and leak-proofing company - Shuangjin's leak-proofing company here in Hefei is quite good.

To decide which waterproofing company is good, you must look at their construction methods for solving waterproofing problems and their previous project cases! It is normal for water leaks to occur in house buildings. Once a leak is discovered, you can reasonably analyze the cause of the leak.

You are raising the issue of water seepage on the wall. Because concrete porous brick materials are commonly used to build houses in China, this material is more prone to cracks and allows rainwater to seep into the home.

The reasons for leakage are analyzed as follows:

Cause (1) There are cracks on the outer facade of the wall. The wall is equivalent to a sponge that absorbs water. Without a protective layer, the wall will If your body is moist, excess moisture will flow into your home.

Reason (2) Water leakage occurs from the gaps between the exterior wall bricks, the exterior wall bricks are not constructed with fine craftsmanship, and sand-gray bricks and other reasons can cause water leakage. It is recommended to find a waterproofing company to waterproof the exterior walls and brick joints.

Reason (3) The quality of plastering during exterior wall construction was poor, the strength of cement mortar was low, and the bonding fastness was poor, resulting in a large number of cracks in the plastering area, which became a pathway for rainwater leakage.

Cause (4) Water seeps around the door and window frames of the exterior walls. The mortar in the masonry gaps under the window sill is not full, and water seeps into the room from the gaps.

Reason (5) Installation engineering problems cause water leakage. Since air conditioning, water pipes and other installations require holes in the wall, if the construction quality is not strictly controlled during the installation, the connection between the pipes and the wall will If the seams are not handled properly, it is easy to leave hidden dangers of water seepage.
