how wall anchors work


Bowing basement walls are a issue that can rapidly turn into one that is much more serious. The purpose of your basement walls is to both keep the soil out and hold up the home above. When the foundation walls are buckling into the basement, this is a sign that they may be in danger of collapsing. If the problem continues to get worse, it is possible the walls could collapse and result in a very expensive replacement or rebuilding of the basement wall in that area. The worst case scenario is the home above could collapse. To repair bowed basement walls, CLS uses a system of specially engineered wall anchors to pull the bowing wall back into place and prevent it from buckling any more. The anchors can be expertly installed in a day and can correct the bowed foundation wall the same day. After the wall has been straightened, the chances of it bucking are very low.


If you have a a crawl space, it is most likely a location that you only go to when there is a problem. This is due to the fact that they are normally improperly closed off and are frequently unkempt, dangerous, and can have critters inhabiting them. They are notorious for having excess moisture issues that could cause problems with the floor joists and even cause mold to grow. Our team knows an ideal way to control problems in crawl spaces is to encapsulate them and seal them off from the exterior. This will control unnecessary moisture and humidity in addition to preventing unwanted pests from getting in. If your floors above the crawl space are sagging, we can install a series of jacks to lift and stabilize the floor joists and correct the sinking floor. To further control extra moisture, we can install a specialized dehumidifier to remove the extra humidity and prevent mold growth.
