One-Part Crystalline Cementitious Slurry – HydroSeal / HydroTank 104
HydroSeal / HydroTank 104 is a high-performance crystalline cementitious slurry designed to provide in-depth moisture protection for concrete structures. When applied to concrete surfaces, its active chemical components react with free lime and moisture within the capillaries to form insoluble crystalline complexes, blocking moisture movement through fine cracks and pores.
Unlike traditional physical membranes, HydroSeal / HydroTank 104 penetrates deep into the concrete, maintaining its structural integrity while allowing vapour permeability. Its ease of application—either sprinkled on fresh concrete or applied as a slurry to cured concrete—makes it a cost-effective and efficient waterproofing solution for large areas.
Key Benefits:
✅ Easy application – Sprinkle on fresh concrete or apply as a slurry to vertical/cured surfaces
✅ Deep penetration – Forms a moisture barrier that cannot be punctured or damaged
✅ Unlimited load capacity – Strength is only limited by the concrete itself
✅ No physical membrane required – Allows seamless ‘concrete to concrete’ placement
✅ Breathable – Maintains vapour permeability while ensuring a dry concrete surface
✅ Cost-effective – Lower material application rate (1 kg/m²) reduces overall costs
✅ Seals cracks up to 0.3mm – Reduces reinforcement steel requirements
Typical Applications:
✔ Pile caps & ring beams
✔ Support plinths
✔ Sealing of concrete surfaces
✔ Moisture isolation in kicker joints
✔ Moisture isolation at internal wall abutments with earth-retained walls
