With Soudal Soudaproof HB, you reliably waterproof basements, lift pits, and masonry against moisture and water ingress. This grey cementitious mortar adheres firmly to mineral surfaces, providing a long-lasting repair for damaged concrete. Simply mix the powder with clean water and apply it with a trowel to a pre-dampened substrate. The heavy-duty formula creates a durable barrier designed to resist both positive and negative water pressure from outside. Once the work is done, you can clean your tools quickly with clean water before the mortar sets, ensuring a dependable, moisture-resistant finish for underground structures.
