Expansion joint assembly and repair

In addition to traditional methods, seal expansion joints can be sealed by applying waterproofing strips or joint profiles that can be moulded in situ, thus avoiding potential damage from structure expansion or contraction.
 

An alternative solution is to inject polyurethane-based hydroactive organic compounds. We normally use mixtures that solidify as a flexible foam (neutral, tasteless, and non-toxic), approved for use with drinking water.
