Product Description
The Polyurethane Foam Foundation Crack Repair Kit 30 ft. w/ Peel Off  Surface Sealer is intended for repairing typical, non-structural wall cracks in poured foundations. The kit includes our CR301 Injection Foam, CR303 Polyurea Paste, and all necessary components to repair up to approximately 30 feet of cracks.

The CR301 Injection Foam is a hydrophobic polyurethane liquid which is designed to stop water infiltration or exfiltration. When the Injection Foam meets water, it reacts with it and then repels any excess water forming a closed cell foam barrier which will not allow water to pass through it. It adheres tenaciously to practically all substrates, wet or dry. Its low viscosity makes it ideal even for repairing hairline cracks. It sets rapidly and expands up to 20 times its original volume to ensure even large cracks or voids are repaired. When cured, it maintains its cured volume with minimal shrinkage and its flexible nature allows it to expand and contract with foundation movement. The CR301 Injection Foam is designed to be used when greater than 20% movement (expansion and contraction) of the substrate is anticipated or where an epoxy repair product is not considered necessary.

The CR303 is a solvent free, polyurea paste adhesive designed to temporarily seal cracks and adhere surface ports prior to the injection of our CR301 Injection Foam crack repair product. CR303 will not cure in the presence of moisture and should not be applied to damp or wet surfaces. It is ideal for do-it-yourselfers and inexperienced applicators or contractors because it is easily removable after
application. It is also relatively fast curing in 3-5 minutes and allows for injection within 30-45 minutes.

Recommended Uses
The CR301 Injection Foam is typically used to stop water leaks coming through cracked or honeycombed concrete, voids between walls and floors, walls and ceilings, expansion joints, cold joints and pipe intrusions. It is used to repair concrete walls, ceilings and floors that are leaking. It is not intended for repairing structural cracks in foundations. The CR303 is recommended for use in temporarily sealing foundation wall cracks and adhering surface ports prior to the injection our CR301 Injection Foam crack repair product.

Surface Preparation & Application
Surface must be dry and free of any dirt, dust, or debris prior to application to insure a superior bond. For some surfaces, it may be necessary to give the surface a profile prior to applying. This can be done by lightly sanding the surface or by profiling with a wire brush. CR303 is not a permanent adhesive and can be easily removed from a surface after application. No need for chiseling, sanding, or grinding off.
