103 Polyurethane cracked concrete foundation walls with cracks larger than 1/8in
Nextstar 103 is a custom polyurethane liquid that is designed to be used with wider cracks in concrete walls where other polyurethanes will shrink after application. Nextstar 103 will stop water infiltration. When 103 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. Nextstar 103 polyurethane does not require water to be injected first and It adheres tenaciously to practically all substrates, wet or dry.
Nextstar 103 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, void fill, and pipe intrusions. It is designed to be used when the crack size exceeds 1/4 in (6mm) or where epoxy is not considered necessary.
