Marithan - Waterproofing Products - Waterproof Junction

MARITHAN is a liquid-applied, highly permanent elastic, cold-applied and cold-curing, water-based, one-component, modified polyurethane membrane used for long-lasting waterproofing.

When MARITHAN is applied, it forms a hydrophobic, 100% waterproofing, permanent elastic, seamless membrane without joints or leak possibilities to protect old and new structures efficiently on a long-term basis.

MARITHAN is based on the innovative PUD-Technology™ of MARIS POLYMERS SA.
