Hydrophobic, Non-Shrinking Mortar for Waterproofing & Tanking Junctions
A high-performance, cementitious repair mortar formulated to prevent water ingress at critical junctions. Designed for use as part of the Sovereign Hey’Di Tanking System, it creates a durable fillet at wall/wall and wall/floor joints and can also be used for patch repairs. Its hydrophobic properties and high compressive strength ensure long-term waterproofing without shrinkage or cracking.
Key Benefits
- Forms watertight fillets at construction joints in tanking systems
- Hydrophobic & non-shrinking—resists cracking and water penetration
- High compressive strength over 40 N/mm²—suitable for structural repairs
- Extended working time up to 5 hours—ideal for complex prep work
- Excellent adhesion to concrete, stone, brick, and blockwork
