AkwaSeal LV is a hydrophobic polyurethane chemical injection grout designed to stop water infiltration through concrete cracks, joints, fractures, and unproperly consolidated areas. AkwaSeal LV is injected as a liquid directly into a leaking crack, fracture, hole or joint. After injection, the grout reacts with water and forms into an expanding foam that fills the void. The cured foam adheres to the concrete within the crack to form an impermeable, elastomeric Seal.
