1800 18 20 20Driveway Re-Levelling
Restore levels, remove trip hazards, and preserve your driveway’s appearance—cleanly and with minimal disruption.
Slab driveways can settle or heave when soils change volume, lose bearing or are mobilised through water ingress. Our targeted ground improvement and controlled re-levelling re-supports the slab and lifts it back toward design level—often without removing the driveway or shutting down access for long periods. We inject engineered resin beneath the slab to fill voids, densify weak soils, and apply measured lift, with outcomes verified in real time.
Why Driveways Move
- Reactive soil cycles (wet/dry) causing shrink/swell and differential movement.
- Uncontrolled fill / poor compaction leading to long-term consolidation.
- Erosion or washout around downpipes, irrigation lines or unsealed panel joints.
- Traffic and point loads (cars, boats, trailers) that overload weak spots.
How Driveway Re-Levelling Works
Assess & Map
We survey levels, locate voids/soft zones, and define injection points away from edges and services.
Targeted Resin Injection
Small holes are drilled and a high-strength expanding resin is injected at appropriate depths depending upon the contributing factors and desired outcome. The resin fills voids, binds loose material, increases bearing capacity, and can gently lift the slab back toward level.
Controlled Lift & Checks
Lift is applied in micro-increments and monitored continuously (levels, joints, falls to drains).
Finish & Verify
Holes are plugged, joints can be sealed, and before/after levels recorded. Where needed, we’ll advise on drainage improvements to prevent reocurrence.
Benefits
Non-destructive
Keep the existing slab—no bulk demolition.
Fast return to service
Resin cures quickly; typical areas useable the same day
Precise
Millimetre-scale control to restore falls and remove trip steps.
Clean workface
Small injection points; minimal mess and waste.
Limitations & Suitability
The slab may be too broken to act monolithically and lift together (multiple full-depth crack fragments, shattered corners, delamination).
Treatment width may be too narrow to correct gradient adequately (insufficient slab size prohibits differential recovery).
Treatment width may be too narrow to correct gradient adequately (insufficient slab size prohibits differential recovery).
Severe root heave is the primary cause—resin won’t counter ongoing tree growth forces.
We’ll perform a level survey to confirm the polarity of movement (heave vs settlement) and the extent of vertical change so you’ll know if ground remediation can realistically restore alignment.
Cost & Decision Factors
Small, isolated sections are often cheaper to replace than to remediate because resin works have a fixed entry cost and mobilisation. Larger areas or multiple panels tend to favour re-levelling, especially where demolition/reinstatement would be disruptive or expensive.
Finish Matters
Exposed aggregate / stencilled concrete are difficult to match on a partial replacement—re-levelling preserves the original look.
Tiled/paved overlays may not be replaceable or available—re-levelling can retain these finishes intact.
Functionality considerations
If settlement has upset drainage, re-levelling can restore falls without a full rebuild.
Typical Issues We Fix
- Sunken panels creating trip steps at garage entries, thresholds, or path interfaces.
- Loss of falls to drains causing ponding.
- Void pumping and slab drumming over soft spots.
- Settled edges at crossovers and vehicle pads.
