Our Foundation Wall Waterproofing Method
We follow a meticulous concrete foundation waterproofing process to guarantee a flawless and durable result.
Initial Assessment & Diagnosis: We conduct a thorough inspection of your foundation to identify the source and extent of water intrusion, assess structural conditions, and determine the optimal waterproofing strategy.
Excavation & Surface Preparation: Our team carefully excavates the soil around the affected foundation walls. The concrete surface is then expertly cleaned via high-pressure washing to remove all dirt, debris, and loose material, ensuring a perfect bond for the membrane.
Crack & Defect Repair: All cracks, voids, and honeycombing in the concrete are meticulously repaired and sealed with specialised epoxy resins and mortars to restore the foundation’s integrity.
Membrane Application: We apply multiple layers of a high-performance, flexible waterproofing membrane. This creates a seamless, impenetrable barrier that permanently prevents water from contacting the foundation walls.
Drainage & Protection: A dimpled drainage sheet and protection board are installed over the membrane to shield it during backfilling and to channel hydrostatic water pressure safely away into a new agricultural drainage system (ag-pipe).
Backfilling & Site Restoration: We carefully backfill the excavated area, ensuring proper compaction, and restore the site to its original condition, leaving your property clean and tidy.

Benefits of Commercial & Residential Foundation Waterproofing
Protecting your home or building starts from the ground up — and foundation waterproofing is one of the smartest long-term investments you can make. Here’s why:
1. Prevents Water Damage and Structural Issues
Waterproofing foundation walls outside or inside keeps groundwater, rain, and moisture from seeping into your structure. This prevents cracks, concrete deterioration, and structural weakening — saving you from expensive repairs down the track.
2. Stops Rising Damp and Mould Growth
Water under slab foundation can lead to moisture entering through the concrete, causing rising damp, musty smells, and mould growth inside walls and floors. A properly sealed foundation prevents water ingress and maintains a dry, healthy indoor environment that’s safe for your family.
3. Increases Building Longevity
By keeping moisture out, you protect concrete, steel reinforcement, and surrounding materials from corrosion. This extends the life of your entire structure — especially important for Gold Coast and Brisbane properties exposed to coastal humidity.
4. Saves on Costly Foundation Repairs
Foundation membrane waterproofing is far more affordable than fixing damage later. Preventing leaks, cracks, and dampness early can save thousands in structural, flooring, and interior repairs over time.
5. Improves Energy Efficiency
Water under slab foundation can lead to excess moisture and humidity inside your home. In contrast, a dry foundation reduces humidity levels, making it easier to regulate temperature. This helps your air conditioning run more efficiently — lowering energy bills and improving comfort.
6. Strengthens Property Value
Homes with professionally waterproofed foundations are more attractive to buyers and insurers. It shows proactive maintenance and long-term protection — a key selling point for Brisbane and Gold Coast homeowners.

Can resin injection for concrete foundations fix basement cracks effectively?
Resin injection for concrete foundations is a non-invasive repair method used to seal cracks, stabilize soil, and restore structural integrity. It involves injecting polyurethane or epoxy resins into foundation voids or fractures, where the material expands and bonds to the surrounding concrete.
This technique is ideal for:
- Waterproofing leaking foundations
- Repairing structural cracks
- Underpinning settled slabs or footings
- Preventing concrete cancer caused by moisture and rusting rebar
In Brisbane and surrounding areas, resin injection for concrete foundation is especially effective due to reactive clay soils and seasonal rainfall. It’s often preferred over traditional underpinning because it’s faster, cleaner, and less disruptive.
