Vetogrout UR710 is a fast and highly reactive polyurethane foam producing resin that is specially used to temporarily stop water. It reacts when in contact with water to form a flexible closed cell foam barrier inside concrete cracks. Vetogrout UR710 is a two-component urethane injection system consisting of foam resin and an accelerator. The product is re-injectable with Vetogrout UR711 to form a permanent elastic seal in structural elements.
