Water has always been the most persistent adversary of engineers and contractors. Structures move due to settling, thermal changes, and aging. These forces cause cracks and other voids allowing unwanted ground water to enter. Chemical Grouts began solving construction problems with flexible resins many years ago. Grouts offer the variety of choices professionals need, to ensure they have the right product for their project. Polyurethanes, acrylics, and acrylates grouts are commonly used to stop running water through cracks and joints in concrete and masonry structures as well as sealing voids.
