Why Use Epoxy and Polyurethane Injections?
Epoxies and polyurethanes are designed to seal cracks and eliminate water and air leaks from basement walls. The crack injection repair process allows for cracks to be completely filled, keeping water and soil gases out permanently.
Epoxy is injected at low pressure, while polyurethane can be injected at either low or high pressure. Epoxy and polyurethane are known as resins. Both are made of two components.
In epoxy, one component is the epoxy resin and the second is a hardener. Both are blended just before a crack injection. It is similar to glue in that it has a strong bond and a hard, plastic-like texture. Epoxies restore the structural integrity of the wall by welding cracked concrete back together. It permanently repairs cracks and creates a bond stronger than that of the original wall.
Polyurethane is made up of the polyurethane resin and an activator, or accelerator. Polyurethane is the more flexible of the two types of resins. When a repaired foundation shifts due to expansion and contraction, it maintains contact with the concrete and moves with the wall to ensure repaired cracks will not re-open.
Our professional team uses high pressure polyurethane foam injection for wider cracks in poured concrete applications involving thick-walled structures (such as dams) or for long cracks in bridges and highways.
Polyurethane injections fill voids and seal pipes. It is the best way to stop a foundation wall leak. The expanding foam completely fills the crack and prevents future water leaks. The water remains outside and cannot penetrate inside.
At Ideal Basement Waterproofing, we use Emecole Metro 102 Premium Polyurethane for repairing wet and leaking cracks. It expands up to 20 times its original volume to fully fill cracks. It is specifically formulated for poured foundation wall crack repair, and it remains flexible.
What Is A Stair Step Crack?
Stair-step cracks are diagonal cracks that occur in concrete block or brick foundations. The cracks begin along a joint or near the end of the wall and moves up or down from there. Most foundations have been engineered to handle the pressure of water and soil, but if they fail, StablWall is a great way to repair the step cracks.
What Causes Stair-Step Cracks?
Stair-step cracks are most commonly caused by excessive moisture issues, or heavy pressure on a specific section of the wall. These problems can be initiated by gutter issues, or a fault in your drainage system. This means that potentially harmful moisture is not traveling away from your home’s foundation as it should. Before installing StablWall, it is important our team identifies and corrects the source of the issue.
What Is StablWall?
StablWall is an effective and economical crack repair solution that utilizes the high strength of carbon fiber to resist any potential future movement. Carbon fiber is light weight, easy-to-install, strong (10x stronger than steel) and non-corrosive, which eliminates the need for maintenance. Carbon fiber can also be easily painted over or covered with a finishing product for aesthetic appeal StablWall is an industry leader in concrete crack repair and structural strengthening, providing strong, efficient and dependable products.
Carbon Fiber Grid Stitch with ERT Crack Repair System has dramatically altered concrete crack repair by integrating carbon fiber stitching with a structural epoxy adhesive. A true structural repair that can be used for vertical or horizontal crack repair. The first commercially available concrete crack control stitching system, Carbon Fiber Grid Stitch with ERT Crack Repair is built to transfer the load away from repair materials, distributing the load to solid concrete and preventing cracking fatigue.
The reinforcement system is a pre-impregnated, bidirectional carbon fiber grid strap. When used with Epoxy injection the grid stitch has more surface area than staples helping make this system successful. The bigger surface are causes a stronger and more efficient bond and ensures better stability for your home.
