Selecting a Polyurethane Chemical Grout to Seal Leaking Structures

摘要

Unlike contractors of years gone by who only had one or two products to use for every application, today's grouter has the benefit of many chemistries to meet the various site conditions. As the situation requires, he can: choose a high expansion hydrophobic to stop fast and high water flows or fill voids; a moderate expansion hydrophilic to seal flexible joints; a flexible hydrophobic for freeze/thaw or wet/dry cycling areas; a polyurethane gel for curtain grouting into soils, or a low viscosity hydrophobic for curtain grouting in freeze/thaw or wet/dry cycling areas or a multi-component grout to overcome special problems. As the range of products grows, so does the need for a strong partnership between the specifier, chemical manufacturer and contractor to support this ever expanding and improving industry.
