How DS Projects Stops Basement Leaks Using Concrete Leak Injection – With 25-Year Warranty & Free Inspection
The Frustration of Persistent Leaks
If you’ve tried waterproof coatings, sealants, or patch repairs and the leak keeps coming back — you’re not alone. Many Sydney homeowners and builders face recurring basement leaks because traditional waterproofing only treats the surface. Once cracks form and water finds a path, coatings can no longer hold back the pressure.
At DS Projects, we take a different approach. Our concrete leak injection Sydney service repairs the problem from the inside out — sealing active leaks directly at their source within the concrete. Backed by a 25-year warranty and a free on-site inspection, we provide long-lasting protection against water ingress repair issues across Sydney’s toughest environments.
The DS Projects Leak Repair Injection Process
We don’t just cover the problem — we eliminate it. Here’s how our proven four-step process works:
1. Leak Assessment and Diagnosis
Our licensed technicians inspect your structure to identify every point of water ingress. Using moisture meters and crack mapping, we trace the leak path and determine the best injection material and method.
2. Preparation and Port Installation
Small entry ports are drilled along the crack line. These allow precise control of resin flow and pressure during injection. The surrounding surface is sealed to prevent resin escape.
3. Resin Injection and Sealing
Using high-pressure pumps, our team injects expanding polyurethane or epoxy resin deep into the crack. The resin reacts with water, expands, and permanently seals the void — even stopping active leaks instantly.
4. Quality Testing and Surface Restoration
After curing, we perform a water test to confirm full watertightness. Once verified, ports are removed and the area is refinished cleanly.
This leak repair injection process delivers a permanent internal barrier — without excavation, demolition, or disruption to the property.
