Crommelin Cemproof Flex Grey 35kg 2 Part Cement Based Membrane

Cemproof Flex

Cemproof Flex is a two-component, flexible cementitious waterproofing product ideal for use in both positive and negative side waterproofing applications and for use direct onto damp surfaces. Once applied and cured, CEMPROOF FLEX provides a non-toxic, flexible and waterproof coating with very high adhesion on those common substrates in construction such as concrete, natural and artificial stone, renders, bricks, concrete blocks, etc
Component A is a water based acrylic resin and Component B is a mortar, based on a mixture of cements, additives and well-graded aggregates.

Features & Benefits

• Provides a fully-flexible coating which ensures waterproofing even in the most severe conditions, resisting high negative water pressure.
• Excellent adhesion and easy to use. Does not require bonding agents and can be applied on wet surfaces.
• Resists hydrostatic negative pressure from ground water when used for underground interior application
• Acts as an anti-fracture membrane between the substrate and other finishing coats applied.
• Excellent protection for concrete, being both a CO2 and Chlorine barrier and thereby preventing carbonation and electrochemical corrosion.
• Permeable to water vapour, allows the substrate to breathe.
• Resistant to abrasion and UV absorption.
• Withstands atmospheric pollution, corrosive effects of salt water and freeze/thaw cycles.
• Non-toxic and chloride-free. Suitable for contact with potable water.
• Covers shrinkage and hairline cracks of the concrete.
• Longer lasting that other coatings, avoiding maintenance costs.
• Environmentally friendly.

Areas of Use

• Waterproofing and protection of water retaining structures, such as drinking water tanks, reservoirs, water mains and swimming pools.
• Waterproofing of below-grade structures like basements, retaining walls, foundations, tunnels subjected to both positive or negative high water pressure.
• Waterproofing and protection of concrete against carbonation, and chlorine penetration in public works.
•  Waterproofing balconies, podium decks and where a UV stable abrasion resistant coating is required.
•  Internal and external waterproofing and protection of new and old buildings.
