Introduction of adjacent housing settlement, adjacent house gap.

Surely a lot of families have encountered cases where the gap between two houses was infiltrated, also known as adjacent settlement. In this article, Hung Thinh waterproofing will share with readers a plan that can thoroughly waterproof for the joint between two houses and some mistakes in handling the joint waterproofing between 2 home.

1. Causes of the leak:

The adjoining rift is usually infiltrated by rainwater that seeps into and penetrates the walls. And because this gap is made up of 2 wall sections on 2 different foundation systems, the settlement and elasticity will be different. Therefore, the materials used to treat adjacent openings must have good elasticity, good long-term rain and rain.

2. Plan for waterproofing of adjacent slits, waterproofing adjacent slits:

There are many alternatives to waterproofing adjacent houses to ensure long-term stability. In European countries, the Sikadur Combiflex® SG option is a very reliable and reliable option, but the price is quite high, so it is rarely used in our country. And this option is preferred for waterproofing of tunnel expansion joints, settlement of settlement problems caused by more groundwater.

Now, the preferred plan in the treatment of openings in adjacent houses, adjacent houses is to insert slots or corrugated roofing with waterproofing membrane materials, specialized waterproofing glue. A common mistake is to use cement + sand mortar to fill the gap, tole, or pour the mortar into this gap, these options have no effect because the mortar has no elasticity, so after only 1 time. When the gap is open and slack, the mortar will expand.

The image above is the part of the mortar that has come apart.
Hung Thin waterproofing please share with readers of the plan of corrugated iron roofing or inserting slits to waterproof the gap of adjacent houses, adjacent slits as follows:

2.1. Cut the groove 2-3cm deep, 1-2cm wide to attach the sheet and use a hand-held grinding machine to clean and roughen the surface of the slit, so that the adhesive adheres to the surface of the wall and corrugated iron. Then, insert the corrugated iron into the groove. If the gap of your house is very small, glue to fill the gap of the adjacent house. The glue you can easily find outside the specialized market for waterproofing is Sika Flexconstruction AP.

2.2. After the glue has been pumped, you fill the surface with glue and apply an open polyurethane waterproof membrane, apply a layer of Poliester or glass mesh to reinforce. Do not use bitumen waterproofing bitumen (Bitumen) for the construction of this gap because the asphalt with poor sun resistance is prone to melting and aging.

In some cases, you can use stainless steel trough to catch water flowing to the drainage area. However, note that the link position of stainless steel troughs must be tight.

In the case of houses that are too close, you do the same but do not need to use corrugated iron, so instead of cutting grooves to make corrugated sheets, cut the gap between the two houses to carry out the glue and the next steps.
