If your garage is partially underground and you’re noticing water pooling in the corner during heavy rain — especially leaking through brickwork — this is a clear sign of hydrostatic pressure and failed waterproofing.
Even a minor leak is a warning that groundwater is building up behind the wall and forcing its way through porous brick or mortar joints.
We specialise in diagnosing and permanently repairing underground and split-level garage leaks in both commercial and residential properties.
In split-level homes, part of the garage often sits below ground level. When it rains heavily:
Bricks are not waterproof. Without proper external membrane protection and drainage, water will eventually find its way through.
Even if the leak seems minor, ongoing moisture exposure can lead to:
We focus on stopping the water at its source — not just sealing the inside.
Depending on the cause, we may recommend:
Every solution is customised to the structure and severity of the issue.
A “minor leak” during heavy rain can quickly escalate during prolonged wet periods. Hydrostatic pressure increases over time, and repeated saturation weakens materials. Addressing the issue early prevents:
Yes — underground brick garage leaks are absolutely something we assist with.
If you’re seeing water coming through bricks in multiple spots during heavy rain, it’s time for a professional assessment.
We’ll identify the cause and provide a clear, practical solution to permanently stop the leak.
