> Water-Stopping Injection Systems
There are several easons why cracks appear in masonry or concrete walls. Many of them may be caused by settlement or shrinkage but sometimes the cracks will be indicative of a more serious underlying problem such as excessive pressure or because of poor construction.
It is essential to establish the cause of foundation cracks before attempting to repair them with water stopping injection systems. Concrete wall cracks that are in excess of 0.63 centimetres or ¼” that are becoming longer or wider, are usually due to movement in foundations and should be inspected by a professional, qualified surveyor.
Minor settlement cracks, although not damaging structurally, can still lead to the ingression of water and Hardisty specialists have a number of water stopping injection systems to repair these efficiently and effectively.
When concrete cures and dries out, it naturally shrinks and the stress of this shrinking process often produces cracks. These types of cracks are easily identifiable by the irregular lines they form in the concrete. They can also travel just a few centimetres or may extend up or across the entire wall. In almost every case, cracks like this will be evident all the way through the wall and will allow water to pass through them.
Before irreversible damage occurs the quickest way to alleviate major problems is to have the wall injected using water stopping injection systems including the injection of polyurethane foam, after finding and fixing the source of the problem.
Particularly effective for basement walls, foam in liquid form can be injected into the largest of cracks and when it comes into contact with water, the polyurethane turns into foam expanding throughout the crack and forming a barrier. Just filling cracks with more concrete will only achieve a temporary repair so you are well advised to consider water stopping injection systems as they are far superior and will last for years.
