how wall anchors work


Bowing foundation walls are a minor problem that can very quickly turn into one that is much more serious. The foundations purpose is to both keep the soil out and hold up the home above. When the foundation walls are bowing into the basement, this is an indicator that they may not be able to do their job for much longer. If the bowing keeps happening, it is possible for the walls to fail and result in you to rebuild or replace the foundation wall in that area. The worst case scenario is the house could collapse. To correct buckling basement walls, CLS uses a system of wall anchors to bring the bowing wall back into place and prevent it from buckling any longer. The anchors can be professionally installed in a day and can straighten the bowing foundation wall the same day. After the wall has been repaired, the chances of it becoming a problem again are very low.


If you have a a crawl space, it is most likely a location that you only visit when there is a problem. This is probably because they are usually improperly closed off and are frequently messy, dirty, and can even have critters holed up in them. Crawl spaces are notorious for having excess humidity problems that could cause problems with the floor joists and even enable mold to grow. Our team knows one of the best ways to control issues in crawl spaces is to encapsulate them and seal them off from the exterior. This will control unnecessary moisture and humidity in addition to controlling the entry of unwanted pests. If your floors above the crawl space are sagging, we will install a system of jacks to lift and stabilize the floor joists and restore the sinking floor. To further prevent extra moisture, we will install a specialized dehumidifier to remove the excess humidity and prevent the growth of mold.

If you've noticed cracking in the foundation or if you're noticing them at the corners of your window or door frames, this is an indicator that there is a problem with the foundation and you may require foundation repair. An additional sign could be the doors or windows are difficult to open or close or even getting stuck when opening them. Settling foundations are commonplace in the North Sioux City area as the moisture levels of the soil fluctuates throughout the year. These issues are occasionally caused by poor compaction when your home was being built. Our experts can install a system of piers under your foundation which will shift the load of your home to the piers and keep the foundation from sinking or settling in the future.
