Common Waterproofing Issues in Marion

Every area of Adelaide has unique waterproofing challenges. Here's what homeowners in Marion need to know.

Aging Waterproofing in Older Homes

Many homes built before modern waterproofing standards (AS 3740) have failing or absent waterproofing membranes. Common issues include leaking showers, damp bathrooms, and water damage to subfloors. Renovations are the ideal time to bring waterproofing up to current standards.

Salt Spray & Membrane Degradation

Coastal locations face accelerated membrane degradation from salt spray. Standard waterproofing membranes can fail prematurely without marine-grade products. Balcony, deck, and roof membranes are especially vulnerable and require UV-stable, salt-resistant systems.
