The locations and extent of the damage or severity of the crack in your foundation determine the type of materials and which methods are best in solving the affected crack vantage. For instance, if you have cracks that is not more than a quarter inches wide, the easy approach is to use gray tinted concrete caulk. This method is great if the severity is absolutely at the minimal stage and it’s at a surface-level.
If you want to fix the cracks permanently, you would need to give your approach a bit of a nudge using a pourable crack filler or fortified patching cements. These patching cements are made up of polymer compounds which inherently enhance the adhesiveness and the bonding properties of the material. If you have a larger cracks on horizontal or vertical surfaces, your sure bet is to let the professional or foundation repair specialists get on this, and fix it permanently to avoid imminent threat that might be posed whenever it rains heavily.
