Durable masonry repair using flexible PU injection resin.

Old or damaged masonry often has reduced load-bearing capacity – caused by missing binders, cavities, washouts, or dissolved joints. Targeted injection can contribute to structural improvement and lasting consolidation.

WILLPUR^® WX is a two-component polyurethane-based injection resin with a variable reaction time. Depending on the environmental conditions, the material either hardens slowly into a tough, elastic, force-fitting resin or reacts on contact with water to form a volume-stable foam.

This allows the load-bearing properties of weakened masonry areas to be restored while reliably sealing potential water pathways.
