Polyurethane 102 Injection Foam for Non-Structural Cracks

Polyurethane for leaking concrete foundation crack repair (walls)

Nextstar 102 is a hydrophobic polyurethane liquid that is designed to stop water infiltration or exfiltration. When 102 meets water, it reacts with it and then repels any excess water forming a closed-cell foam barrier that will not allow water to pass through it. It adheres tenaciously to practically all substrates, wet or dry.
Nextstar 102 is typically used to stop water leaks coming through cracked or honeycombed concrete, voids between wall and floor, wall and ceilings, expansion joints, cold joints, and pipe intrusions. NextStar102 is designed to be used when greater than 20% movement (expansion and contraction) of the substrate is anticipated or where epoxy is not considered as necessary.
