Waterproofing in Chelmer

Chelmer sits on the river and floods, so the brief often reaches below the floor: damp subfloors, retaining walls and the odd basement that has to hold back ground water, not just shed it.

Above-ground balconies and decks waterproofed to AS 4654, with the fall to drain and the upturns detailed right so water leaves instead of pooling.

Exposed and buried membranes on roofs, podium decks, planters and trafficable terraces to AS 4654, in the system that suits the exposure and the traffic.

Basement & Retaining Wall Tanking

Below-ground tanking for basements and retaining walls, built to hold back negative water pressure instead of just painting over the damp.

Remedial Leak Repair

Leak diagnosed first, then a shower re-seal or membrane make-good, so we fix the cause once rather than seal over it and watch it leak again.

Planter Box & Water Feature Waterproofing

Planter boxes, ponds and water features tanked and detailed so constant standing water and root pressure do not find their way into the structure.

Reviews

What Chelmer owners say.

★★★★★

“Our basement was damp every wet season and the last mob just painted it. Sealline assessed where the water was coming from and tanked it from the inside with a proper negative-pressure system. First wet season since and it is dry.”

Local questions

Waterproofing in Chelmer, answered.

Do you charge extra to come to Chelmer?

No. Chelmer is within 30km of our Murarrie base, so there is no travel surcharge. The site inspection and the by-the-m² quote are the same whether you are around the corner or at the edge of the radius.

How soon can you look at my leak in Chelmer?

We aim to be on site for an inspection within 48 hours, faster for an active leak, and to have the written quote back to you within one business day of inspecting. The job itself depends on the membrane system, the drying and curing times, and any strip-out, and we give you a realistic window on the quote. A wet area is usually a one to three day job once we start, and curing between coats sets the pace, not us.

Will the membrane actually hold around Chelmer?

Only if it is built to the Standard, which is exactly what we do. We check the substrate and the falls on the inspection, prep and prime, detail the bond breakers and the upturns, apply the coats AS 3740 or AS 4654 asks for, then flood-test before anything goes on top. A single-coat surface seal leaks again within a couple of summers, so the membrane workmanship is the part our 10-year warranty covers.

Can you work with our body corporate or strata in Chelmer?

Yes. We do a lot of podium decks, planters and balcony remediation on body-corporate and strata buildings, where a committee or a building manager has to sign off the system, the staging and the cost. We give you a clear itemised quote you can put in front of the committee, name the work to AS 4654, coordinate access around residents, and hand over the compliance certificate, so the approval and the sign-off are the easy part.
