CarboStop UPlus

CarboStop U Plus is a water-reactive single- component resin with integral catalyst.

CarboStop U Plus is free of CFC and phthalate plasticisers. CarboStop U Plus consists of modified polyisocyanates with additives.
CarboStop U-Plus cures by reaction with ambient water yielding a polyurethane/polyurea foam.

The expansion rate of the foam depends in the first place on the back pressure effected by the propagation of the resin into the structure to be sealed, i.e., wide cracks/gravel result in a high foaming factor, narrow cracks/ sand in a low expansion rate and high strength.

CarboStop 402

CarboStop 402 resin consists of modified isocyanates with additives. CarboStop 402 ACC is a catalyst mixture designed to adapt the reaction speed to the situation.

To adapt the reaction speed, the accelerator CarboStop 402 ACC is added to the resin and mixed before pumping.

The reaction begins when the mix comes in contact with water. The reacted material has a high amount of closed cells under compressed as well as free rise conditions.
