Thornlie is the largest suburb in the City of Gosnells, and the Canning River runs through its northern side — which means drainage is a real consideration for retaining walls built on that side of the suburb.
We install modular block, limestone, and concrete post and panel retaining walls designed around the grade and water flow specific to your block. Every wall is checked for lateral soil pressure before we recommend a type.
Garden terracing, driveway retaining, and boundary walls are all part of what we build across Thornlie's established family streets.

Concrete Post & Panel
Structural retaining for driveways and sections near the river's northern side.
Limestone Walls
A natural finish for garden edging on established family blocks.
Modular Block
An affordable option for garden terracing on flatter sections.
Drainage-Aware Retaining on Thornlie's Riverside Streets
Blocks on the northern side of Thornlie, closer to the Canning River, see more water movement through the soil than the rest of the suburb. We assess site drainage before recommending a wall type, so it holds through Perth's wetter months rather than shifting over time.

How much does a retaining wall cost in Thornlie?
Retaining wall costs in Thornlie typically range from $250–$550 per square metre, depending on wall height, material, and site access. These figures are indicative — book a free on-site inspection for an accurate quote.
Do I need council approval for a retaining wall in Thornlie?
In the City of Gosnells, retaining walls over 500mm high, or built on or near a boundary, generally need council approval and may require an engineer-certified design.
Does living near the Canning River affect retaining wall design?
Yes — blocks closer to the river see more water movement through the soil, so proper drainage design behind the wall matters more than on a typical flat block.
What's the best retaining wall material for Thornlie's blocks?
Concrete post and panel is generally best for structural, load-bearing sections, with limestone or modular block used for garden terracing.
