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.

Gas-Resilient Concrete Starts with MasterLife WP 799

Reduced Air Permeability:

Unlike other technologies, MasterLife WP 799 significantly decreases concrete’s porosity, improving its resistance to the movement of gases—making it suitable for applications where radon and methane barriers are critical.

Ideal for Ground-Gas Risk Areas:

Use in combination with physical gas membranes or as part of an integrated strategy for protecting basements, car parks, lift pits, and other below-ground structures from hazardous gas ingress.

Certified Durability:

Backed by third-party testing and BBA Certification (21/5887), MasterLife WP 799 gives specifiers confidence in both WaterProofing and gas-resilience performance.

Applications

• Basements & underground car parks

• Lift pits & plant rooms

• Retaining walls & podium decks

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

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
