Nitofill PU140
Nitofill PU140
Nitofill PU140 is a multi-purpose, single-component polyurethane injection resin that reacts with water to expand and seal leaking cracks, joints and voids, forming a durable, impermeable elastomeric seal to stop water ingress.
Typical Applications
- Sealing active water ingress in concrete structures
- Sealing leaking cracks and joints
- Stopping water ingress in masonry and brickwork
- Void filling in concrete and masonry structures
- Back grouting in inaccessible or confined areas
Advantages
- Single-component polyurethane injection resin
- Reacts with available water to initiate expansion and seal leaks
- Rapid formation of a semi-flexible, closed-cell foam to stop water flow
- Forms a tight, impermeable elastomeric seal that accommodates movement
- Effective even when reacting with sea water or mineral water
- Suitable for injection into cracks, joints and voids in generally inaccessible locations
