Category: PU Grouting

The use of polyurethane grouts can stabilize soils, fill voids, and seal leaking infrastructure. A common but poorly understood method of repair uses polyurethane chemical grouts that react with water. They either bond with the concrete to create a permanent seal or become rigid to fill voids, stabilize soil and protect against water damage. Since...

Molds that grow in moisture can cause health disorders, and the musty smell emanating from a basement is unpleasant. Leaky foundation walls in commercial structures can cause a similar type of damage. Seepage or flowing water may occur through cracks or penetrations in concrete walls. The cause of this issue is often a failure of...

A common method for applying grout is to drill a hole next to the leak, inject the material through the hole with water pressure, and then use a trowel, sponge, or other tools to work it into the crack. The oldest method of repairing concrete structures often requires the use of polyurethane chemical grouts. These...

When repairing a foundation wall with an epoxy or polyurethane foam polymer, it’s best to inject the material at low pressure. To ensure that a crack injection is effective, the liquid polymer must be gradually introduced into the crack at low pressures (20 to 40 psi). This method may take longer than other filling techniques,...

You’ve spotted the signs, cracked walls and floors, leaky plumbing, and sticky doors. You know your foundation is in trouble and in need of repairs but what options do you have? The type of repair you need will depend on the soil type, climate, foundation build, and any additional outstanding problems. Non-structural cracks in foundations...

The Pressure Injection System The Pressure Injection System can be used for injecting cracks, cold joints, expansion joints and for soil stabilization. The system can be used to stop gushing water, to seal minorseepage, to regain structural integrity and to waterproof and strengthen almost any concrete ormasonry structure from the positive or negative side, below grade,...

How to seal cracks in concrete floors, foundations, walls, or other masonry: this article how to seal and repair of cracks in poured concrete slabs, floors, or walls. We list all of the current methods used to seal control joints or cracks that occur in those building surfaces, giving the properties, general procedure, and pros...

Filling cracks with injection grout is a useful procedure that helps provide waterproofing and corrosion protection for structural purposes. A variety of grouts are available on the market with different characteristics, properties and uses. Generally, grouts used for crack repair should have low viscosity, high bond strength, low shrinkage and high stability at the repair...
