Crystalline, in-depth penetration waterproofing system

MaxProof 440 is a cement-based, crystalline, in-depth penetration waterproofing system for concrete and cement-based substrates. It forms insoluble crystalline complexes into capillaries which ensures permeant waterproofing solution to water leakage in concrete structures and cement-based substrates. MaxProof 440 is equally effective against positive and negative water pressure and prevents further passage of water.

Features and benefits

• Does not rely on film formation. Forms an integral waterproofing system and will not delaminate, peel off or wear away.
• Permanently active. Crystalline formation will be re-activated by contact with water.
• Non-toxic. Suitable for use in contact with potable water.
• Can be applied to damp substrates.

Coverage:
Brush application: 0.75 kg/m²/coat (two coats are required).
Dry Sprinkling application: 1 kg/m².

• Water retaining structures such as: water tanks, swimming pools, potable water and waste water treatment plants and sea water channels.
• Water excluding structures such as: basements, tunnels, bridge decks and sea defense walls.
• Foundations, retaining walls and backfilled elements.
• Horizontal construction joints.
