HydroTank 308 Stopaq is a highly flexible, single-component sealing compound designed for sealing conduits and pipes through service duct sleeves. This permanently flexible, re-usable pipe sealant effectively stops water and gas ingress, even under active leaks and high water pressure conditions.
Unlike traditional sealants, HydroTank 308 Stopaq never cures, allowing new services to be pushed through the existing seal and re-sealed effortlessly. It swells up to 10% upon contact with water, forming a high-performance seal against water pressures up to 3m.
For a complete installation, HydroTank 308 Stopaq Mortar is used to cap the seal, ensuring a secure, non-shrinking, and fibre-reinforced finish that allows for future conduit modifications without power tools.
