What do we do?
What exactly is it that we do at Arrow Injections? We repair leaky concrete walls from basements to cisterns and anything in between. We use a low-viscosity polyurethane resin designed for single-component injection. It penetrates fine cracks and reacts with water to form a flexible foam barrier that stops flowing leaks and seepages. Once cured, the hydrophobic seal repels water, will not shrink or expand, and serves as a long-term solution to water infiltration.
