Basement Waterproofing with Hydrepoxy

Hydrepoxy (ARDEX WPM 300) is a liquid-applied, two-part water-based epoxy membrane used as a powerful moisture barrier for basement floors and walls. Unlike traditional surface sealers, Hydrepoxy can be applied directly to damp or green concrete—essential in Auckland’s humid conditions where basements often never fully dry out. It chemically bonds to a wide variety of substrates, including concrete block, brick, and stone commonly found in New Zealand homes. Its water-based formula ensures low odour and safe application for families, while providing robust resistance to water under high pressure.

Key Benefits:

• Handles real NZ moisture challenges: From rising damp to heavy flooding, Hydrepoxy remains watertight, stopping leaks before they enter the living space.

• Long-term value: Case studies show North Shore families have used Hydrepoxy to transform once-damp basements into recreation areas, home offices, and workshops—maintaining dry, healthy air for kids and adults alike.

• Flexible and versatile: It is suitable for both positive-side (outside) and negative-side (inside) waterproofing, meaning you don’t need expensive excavation for many repairs.

• Code compliant and safe: Complies with drinking water standards; it is safe for areas where water tanking and backup supply might be involved.

Why Professional Application Matters:

• The surface must be cleaned and prepped (holes filled, contaminants removed) before application.

• Typically applied in two coats for maximum moisture resistance.

• Integration with drainage or other renovation work is possible—Auckland Waterproofing Experts develop tailored plans for your property.

• Backed by technical support and warranties for long-term peace of mind.

In Summary:
Choosing Hydrepoxy for basement waterproofing in Auckland is a smart investment in both your property and family’s well-being. It’s a proven, robust solution that addresses both immediate leaks and long-term moisture risks, ensuring healthy, usable basement spaces for years to come.
