CarboStop U

CarboStop U is a water-reactive single-component resin with integral catalyst, free of CFC and phthalate plasticisers. The product is ready for use without mixing.

CarboStop U consists of modified isocyanates with softeners and additives. It cures by reaction with ambient water yielding a polyurethane / polyurea foam.

CarboStop U stops water inflows and provides a temporary seal, which often is satisfactory for the sealing of excavation sites during the construction work.
