Polyurethane Chemical Grout
Avoid installing gels in expansion joints or cracks that are subject to movement. Gels form a solid material with little or no cellular structure to disperse tension under compression. This tension can split the gel and damage the seal.
Avoid installing hydrophobic chemical grouts for repairing minor leaks in cracks or joints. The repair will be temporary.
Don’t get in a hurry when repairing tight cracks and minor leaks. These can be the most difficult to repair long term.
As our infrastructure ages, chemical grouting will continue to maintain its value as one of the easiest, most cost-effective and longest-lasting repair solutions available.
“If the right polyurethane chemical grout is chosen for your repair project and the correct installation techniques are used, the repair will actually outlast the structure,”
