2018 ICRI Paper: Leak Mitigation of Dynamic Cracks

Published Year: 2018

  • Concrete will crack – that is a fact.However, since concrete constantly shrinks, expands, and often leaks, the use of a flexible polyurethane resin to permanently seal active water leaks is the optimum choice to create a water-free environment.
