Crack Seal Solutions

Why do cracks form in basement walls? 

After foundation walls are formed and poured, during the curing process the concrete shrinks as the walls harden. This often results in common, small hairline cracks. Other cracks may form due to slight settlement action in the foundation. And lastly, some cracks form when larger, more serious movement takes place in the soils beneath the structure, causing extreme settlement and noticeable shifting in the foundation or house walls. While we do fix all types of foundation issues, please note this section focuses on the crack sealing aspect of the project.

How do we seal foundation wall cracks?

Crack Seal Procedure

For most crack seal procedures, we use a low-pressure injection process with a polymer or epoxy used to seal the crack. Injection surface ports guide the polymer to the needed voids and effectively waterproof the crack. It's best to apply slowly to watch the effects of the liquid polymer, ensuring every inch is covered.

Fill Voids Through Entire Wall

Water trapped inside a foundation wall can cause damage and have a negative effect on the integrity of the concrete wall. The crack seal process should entirely penetrate the crack and reach all depths to effectively seal out the water and prevent any damage. When possible, also apply a seal on the outside of the foundation wall as well.

We Don't Leave a Mess!

The crack seal process can be messy. We pride ourselves in doing the job correctly and in cleaning up after ourselves. This includes the look on the wall, not just the surroundings. Nobody wants a messy looking substance sticking to or dripping down their wall.
