MAXSEAL FLEX -M

MAXSEAL FLEX -M is a one-component cement-based mortar, which when mixed only with water provides a high-performance flexible coating for waterproofing and protecting concrete and masonry against both positive and negative hydrostatic pressure.

Its advanced formulation forms a continuous, elastic and breathable barrier that prevents water ingress and aggressive agents while allowing the substrate to breathe. MAXSEAL FLEX -M integrates with concrete by sealing pores and microcracks, offering excellent durability and minimal maintenance. It provides reliable protection against CO₂ ingress, chloride and sulphate attack, freeze-thaw cycles, UV radiation and marine environments. With high crack-bridging capacity greater than 0.5 mm, resistance to root penetration and compatibility with ceramic or decorative finishes, MAXSEAL FLEX-M is a versatile and effective solution for civil works, hydraulic structures and building applications. Non-toxic and suitable for contact with potable water, it is also environmentally friendly.

Applications

• Waterproofing of tanks, reservoirs, dams, channels, swimming pools and fountains.
• Internal protection of basements, tunnels, galleries and elevator shafts against negative hydrostatic pressure.
• External waterproofing of foundations and retaining walls exposed to aggressive water or ground salts.
• Protection of concrete in water treatment and wastewater plants.
• Waterproofing of roofs, terraces, balconies, planters and garden areas subject to root penetration.
• Internal waterproofing of bathrooms, kitchens and other wet areas in residential buildings, hotels and hospitals.

Advantages

• Flexible coating with crack-bridging capability greater than 0.5 mm.
• Acts as an anti-fracture membrane between substrate and finishing coat.
• Excellent resistance to CO₂, chlorides, sulphates, freeze-thaw cycles and aggressive environments.
• Breathable, resistant to abrasion and UV radiation.
• Safe for potable water, non-toxic and solvent-free.
• Long service life with minimal maintenance, resistant to root penetration.
• Easy application by brush, roller, broom or spraying equipment.
