Cementitious Waterproofers & Additives for Concrete Protection

Enhance the durability and water resistance of concrete structures with Clever Shield’s cementitious waterproofers and additives. Designed for long-term protection, our products safeguard foundations, basements, retaining walls, and moisture-prone areas.

Cementitious Waterproofers:

Flexible Cementitious Waterproofing Slurries – Seamless, crack-bridging coatings that prevent water ingress.
Crystalline Waterproofing Systems – React with moisture to form insoluble crystals, sealing pores and micro-cracks from within.
Brush or Spray-Applied Coatings – Easy-to-apply layers for positive and negative side waterproofing in pools, tanks, and tunnels.

Additives for Enhanced Protection:

Waterproofing Admixtures – Reduce permeability, shrinkage, and improve workability.
Plasticisers & Superplasticisers – Increase fluidity, strength, and ease of compaction.
Hydrophobic Pore-Blocking Additives – Repel water by sealing concrete pores for extra moisture protection.

Clever Shield’s high-performance waterproofing solutions ensure long-lasting resilience for concrete structures in demanding environments.
