If drainage, waterproofing, or stormwater systems have already been
installed and you’re still dealing with water issues, the problem isn’t
bad luck — it’s failed design or poor installation.
Unfortunately, this is one of the most common issues we fix across Sydney.
At Aqua Flood Solutions, we specialise in fixing failed drainage and flood prevention work
— whether it’s from rushed installs, poor planning, or cost-cutting.
Depending on what we uncover, solutions may include:
Redesigning drainage layouts to suit the site
Correcting pipe gradients and depths
Replacing undersized or incorrectly installed pipes
Fixing pit levels to eliminate backflow
Rebuilding retaining wall drainage systems
Integrating surface and subsoil drainage properly
Correcting waterproofing failures caused by pressure
We don’t just add more drains — we fix what’s wrong with the system as a whole.
If It Was Done Once
and Still Fails — It Needs
Fixing Properly
If you’ve already paid for drainage work and still have water problems, it’s time for a proper diagnosis.
Fixing the design now prevents repeated damage and escalating repair costs.
