The Invisible Shield in Every Pour

When it comes to safeguarding below-ground structures, the best defence is integrated from the start. MasterLife WP 799 Hydrophobic Admixture works within the concrete itself, creating a permanent barrier against water penetration — helping your project meet the latest BS 8102:2022 requirements for below-ground WaterProofing.

Why Choose Hydrophobic Admixtures?

Permanent, Integral WaterProofing

Mixed directly into the concrete, our admixtures repel water throughout the entire structure — no membranes or coatings required.

Resists Capillary Action

Hydrophobic molecules line the pores of the concrete, blocking water pathways while maintaining breathability.

Designed for Type B WaterProofing

Ideal for reinforced concrete basements, foundations, lift pits, and retaining walls, adding extra resilience where it matters most.

BS 8102:2022 Support

Meets British Standard recommendations for the design and construction of WaterProof structures below ground, ensuring robust and reliable performance.

Low Maintenance

Because the protection is built-in, there’s nothing to replace, repair, or reapply over the life of the structure.

Applications

• Basements & underground car parks

• Lift pits & plant rooms

• Retaining walls & podium decks

• Water-retaining structures (pools, tanks, reservoirs)

How it Works

When added to the concrete mix, the hydrophobic agents coat the capillaries and micro-pores within the hardened concrete. This treatment repels water at a molecular level, reducing permeability without affecting the workability or strength of the concrete.

BS 8102:2022 – Built-In Compliance

The latest British Standard highlights the importance of integrated WaterProofing for long-term protection. Hydrophobic admixtures help you:

• Achieve a continuous, watertight structure

• Minimise risk of water ingress at construction joints

• Reduce reliance on external membranes or secondary systems

The Invisible Shield in Every Pour - Choose MasterLife WP 799 Hydrophobic Admixture for a simple, permanent way to protect against water ingress and achieve compliance with BS 8102:2022
