Water pooling around houses
Flooding lawns and sections
Driveways washing out or staying wet
Water seeping through blockwall or foundation wall to interior of house
Downpipes or soak holes not draining properly
Poor ground levels causing runoff issues
Surface drainage systems
Soak pits
Channel drains
Trenching and pipe installation
Connecting downpipes to proper drainage
Ground reshaping to direct water flow
If water is coming through your block wall into your house, or retaining wall is failing, it's usually a drainage issue.
Water builds up behind the wall if drainage systems are blocked or failing.
We fix it by:
Excavating along the outside of the wall
Installing drainage coil (Novaflo)
Adding scoria backfill for free drainage
Using filter cloth to prevent blockages
Creating proper outlets for water
This removes the pressure behind the wall and stops water getting inside.
Small drainage issues turn into bigger problems fast:
Damage to foundations
Driveway failure
Ongoing water damage inside the home
Expensive repairs later
Fixing it early is always cheaper and more effective.
