TamPur 138
Overview
TamPur 138 is a single-pack, MDI based, low viscosity polyurethane grouting system. The resin reacts vigorously when it comes into contact with water, producing a semi-flexible polyurethane foam.
Saline and sea water tolerant
Key specification
- High expansion hydrophobic water stop injection foam
