Landscape drainage in Brisbane needs to suit the way your outdoor spaces collect and shed water during intense summer storms. Sloping blocks, lawns, garden beds, paved areas and downpipe outlets can all contribute to the same wet patch.
Start with the flow path and the surfaces you want to protect. Surface collection, changes to levels or below-ground drainage may be considered after the source, ground conditions and receiving arrangement have been assessed.
We effectively drain waterlogged garden beds with subsoil pipes and gravel, helping plants establish healthy roots and preventing the soggy soil that causes dieback, fungus, root rot and poor growth.
Lawn Drainage
Soggy, spongy lawns are fixed by installing French drains, regrading low spots and connecting to suitable outlets, helping your grass dry out faster after rain and stay green and healthy.
Retaining Wall Drainage
We install drainage behind retaining walls using quality slotted pipe, gravel and filter fabric, relieving water pressure and helping your wall stay straight, stable and free from cracking and bulging.
Terrace and Slope Drainage
On sloping blocks, water can erode soil and flood lower areas. We install swales, drains and pits that control runoff across terraces, paths and steps, protecting your garden and home.
Courtyard and Pool Area Drainage
We drain courtyards, entertaining areas and pool surrounds with discreet channels, grates and pits, keeping surfaces safe, clean and dry while blending seamlessly into your existing paving and landscape design.
Connection to Stormwater
We connect all landscape drainage to approved stormwater outlets, kerb connections or soakwells, ensuring water leaves your garden legally and safely without affecting neighbours or damaging your home or garden.
Questions worth asking
Frequently Asked Question
Can drainage be added to an established garden?
Access, roots and finishes need to be considered. Share photographs and identify planting or paving you want to retain so the route and restoration can be discussed.
Will a gravel trench fix a wet lawn?
Clay soils often drain slowly, so a trench with no outlet may simply hold water. It depends on the water source and outlet arrangement. The collection method should follow an assessment rather than be assumed from the symptom alone.
Garden grading
Shaping garden beds so water leaves the house
Beds that slope toward a wall invite damp, mould and slab trouble. Subtle changes to garden levels can send rain away from the house without changing how the yard looks.
Gentle levels steer water away from the house.
Stand outside during rain and watch where water travels. Garden beds, mulch and raised edges can dam flow and push it back against footings. A gentle fall away from the building, with clear paths to a grate, swale or approved discharge point, helps. Keep mulch below weep holes and slab edges, and check levels again after settling.
01
Fall away from walls
Aim for ground that drops gently away from the building rather than pooling against slab edges or stumps.
02
Mulch depth
Heavy mulch piled against walls can block weep holes and hold moisture. Keep it clear of brickwork and cladding.
03
Watch a storm
Observing a real downpour shows paths water takes and low spots that a dry-weather walk-through easily misses.
04
Clear outlets
Make sure every garden grate or pit stays free of leaves and mulch so water has somewhere to go.
Terraced gardens depend on water escaping behind walls.
Sloping blocks
Drainage behind retaining walls on hillside blocks
Retaining walls hold back soil, and soil holds water. Without a path for that water to escape, pressure builds behind the wall, especially during intense subtropical summer storms.
Terraced gardens on hills-edge Brisbane blocks often rely on retaining walls to create flat areas. Ask whether walls have drainage behind them, such as agricultural pipe, gravel and outlets, and where that water is meant to go. Look for weeping stains, bulging or leaning sections, and soil washing through joints. Raise concerns with a qualified professional early.
Drainage behind walls
Ask whether gravel and slotted pipe sit behind the wall and where that water discharges, not just whether the wall looks sound.
Weep points
Weep holes and outlets should stay clear. Blocked ones can let water build pressure behind the structure.
Warning signs
Leaning, cracking, bulging or soil washing out at joints are reasons to seek professional advice.
Uphill runoff
Water arriving from uphill driveways or neighbouring land can overload a wall. Note where it comes from.
On-site disposal
Garden soakaway pits for lawns and planted areas
A soakaway pit lets collected rainwater infiltrate the ground slowly instead of racing across the yard. In reactive clay it needs careful thought, and sometimes a different approach altogether.
Slow-draining ground can limit what a soakaway pit achieves, and positioning matters. Keep pits well away from house footings, boundaries and neighbouring structures, and make sure overflow has a safe route. Ask your plumber or drainer how the design suits your soil and whether Council requirements apply. Inspect lids after storms and clear silt, since sediment steadily reduces how well they work.
Pooled water after rain shows how well a pit performs.Inspection lids allow silt checks and cleaning.Positioning matters, particularly in slow-draining clay.
Soil mattersClay holds water. Ask how your ground drains and whether a pit alone will cope in a heavy storm.
Keep distancePlace pits away from footings, slabs and boundaries, and follow advice on setbacks from a qualified professional.
Plan the overflowWhen a pit fills, water must still go somewhere safe. Confirm the overflow path before installation.
Inspect and cleanCheck lids after big rain and remove silt or leaves. Sediment slowly clogs the surrounding ground.
