how wall anchors work


Buckling basement or foundation walls are a issue that can quickly become very serious. The foundations purpose is to both keep the soil out and hold up the home above. When the foundation walls are bowing inward, this is an indicator that they may not be able to support the building much more. If the problem keeps happening, it is possible the walls could collapse and result in a very expensive replacement or rebuilding of the foundation wall in that area. The worst case scenario is the building could collapse. To fix buckling foundation walls, CLS uses a system of wall anchors to bring the wall back into place and permanently prevent it from bowing again. These anchors can be installed in a day and can straighten the bowed foundation wall the same day. Once the wall has been straightened, the chances of it bowing more are almost none.


If your homes got a crawl space, it is likely an area that you only worry about when there is an obvious problem. This is due to the fact that they are usually poorly sealed and are frequently unkempt, grimy, and can even have critters holed up in them. Crawl spaces are known for having excess humidity issues that can cause problems with the floor joists and even cause mold to grow. Our experts know one of the best ways to prevent problems in this area is to install an encapsulation system and seal them off from the weather. This will control excess moisture and humidity as well as preventing unwanted pests from getting in. If you have sloping floors above the crawl space, we can install a system of jacks to lift and stabilize them and level the sagging floor. To further prevent extra moisture, we can install a specialized crawl space dehumidifier to remove the excess humidity and prevent mold growth.

If you're seeing cracking in the foundation or if you've noticed them at the corners of windows or doorways, this is an indicator that there are problems with the foundation and you are in need of foundation repair. Another sign could be the doors or windows being difficult to open or close or even not moving when moving them. Sinking foundations are commonplace in the Yankton area due to the moisture levels of the soil fluctuates during the year. These issues are also caused by poor soil compaction when your home was being built. Our experts can install a piering system under your house that will shift the weight of the home to the piers and keep the house from sinking or settling in the future.
