Cracks in concrete can occur for various reasons, such as setting or shrinking, or because of a faulty design or problems in the construction process. Water bearing cracks are cause for particular concern because they can lead to corrosion of reinforcements, and jeopardize the building’s safety. Methacrylate crack injection systems offer a simple and effective solution for filling and sealing the cracks. This prevents water from entering and provides durable protection. These systems also display a strong bonding capacity to concrete, thus providing outstanding structural integrity. The material’s viscosity is very low, which enables a high degree of penetration.
Compared to conventional sealers, methacrylate reactive resins are solvent-free, fast-curing, and enable rapid turnaround. Furthermore, they are compatible with methacrylate coatings and they improve weather and aging resistance. The monomer system is composed of 95 wt% of VISIOMER® MMA or any other high molecular weight methacrylate, and 5 wt% of VISIOMER® TMPTMA.
