Masterseal 910 10mm x 10m Rolls ( 3 per box )

Benefits:

• Swells in contact with water by up to 200% - prevents water ingress even when the joint width varies.
• Water molecules held by molecular attraction – captured water does not get transported through capillaries.
• The volume expansion effect is equally effective in fresh water so as in high salt content water (sea water, brackish water).
• Resistant to chemicals, solvents, fuels and oils.
• Controlled swelling – minimise the risk of damage to concrete.
• Does not form foam or gas with water – durable seal as no air bubbles can breakdown and allow leaks.
• Outstanding chemical resistance.
• Reversible swelling process.
• Resistant to micro-organisms formation.
• Can seal joints with up to 5 bars water pressure.
