We’re going to talk about ways how we can repair cracks in the basement wall.

But before we go into that, it is important to first understand the causes of crack formation.

How do cracks form in the basement wall?

Cracks can occur due to shrinkage of the building materials, thermal influences on the structure, changing loads on the structure as well as movements in the soil on which the structure is built. Minimal expansion cracks are basically harmless. But it is important to keep a close eye on these so that they do not become large cracks. Because water problems often arise as soon as (large) cracks are present in the wall of the basement.

This water causes leaks, which affect the quality of the basement, resulting in moisture problems and mold. Cracks can also affect the structure and has structural integrity. Cracks under a construction beam are very dangerous because they indicate that the beam cannot support the construction sufficiently. That will give a structural problem.

Expansion cracks in concrete walls should be repaired before they become major cracks. In addition, it is of great importance to repair constructive cracks. But what ways are there to repair cracks in the basement wall?

How to repair a crack in the basement wall

Cracks in the basement wall can be repaired in several ways. There are various products and methods on the market.

Small expansion cracks are often closed with silicone or mortar. This is a temporary solution, as silicone and mortar is flexible to accommodate expansion movements, but for a short period of time. This eventually creates cracks in the wall of the basement again.

There are also epoxy injection methods in which a liquid, such as a gel or a resin, is injected into the crack wall of the cellar. These fluids are repairing cracks that are visible to the eye. But cracks are often also present deep in the material. These cracks are not always achieved with these methods.

So what is a good method to repair cracks in the basement wall?

When repairing expansion cracks as well as larger cracks, it is important to use a flexible product that can accommodate expansion and natural movements in the concrete walls. In addition it is important when repairing cracks with a liquid, that the liquid can reach deep into the pores of the material, so that the most minimal cracks that are present in the wall are also closed.

When we are looking for a flexible product that also closes the most minimal cracks in the wall, we quickly come to the Logic UH mortar and the Logic UW Flex injection resin. Below I will explain these products:

  • Logic UH mortar

This is an innovative and durable mortar that is suitable for repairing cracks in the basement wall. The distinctive character of this mortar is its ability to conform to the crack while simultaneously absorbing expansion and natural movements. Logic UH mortar is an resin that is mixed with sand to be stronger than concrete and can provide effective repair for 20 years.

Logic UW Flex
This is a high-quality epoxy injection method that uses a resin. This method is used to repair the most minimal cracks in the wall. When mentioning minimal cracks, we refer to cracks that are not easily visible to the eye but are present in the wall. Thanks to its technical composition, the Logic UW Flex makes it possible to reach all the pores in the wall and then fill them.

Both the Logic UH mortar and the Logic UW Flex are composed by a special technology that is smaller than NANO. This technology makes it possible for the products to have a high creep capacity, reaching pores in the wall to a deep point.

After these pores have been reached, they are filled with the product and the cracks are therefore closed for a long time. In addition, both the Logic UH and Logic UW Flex can be used on wet surfaces. So if there is already a leakage, these products can offer a solution. In this way structural problems, cracks in concrete walls are prevented or repaired.

In this way the cracks in your cellar wall are repaired and protected against the formation of new cracks for a duration of 20 years!
