Retaining wall questions, answered properly.

A1 Retaining primarily constructs concrete sleeper retaining walls and gabion retaining walls.

The appropriate system depends on wall height, slope, soil, access, drainage requirements, nearby structures and the finish wanted for the property.

Concrete sleepers do not rot or attract termites like timber. However, the performance of the complete wall also depends on suitable posts, footings, drainage and backfill.

Water around the property still needs to be managed after the wall is completed.

A gabion wall uses wire cages filled with rock. It creates a strong, textured appearance and may suit properties where a natural-looking retaining system works with the landscape.

There is no single wall system that is best for every property. The decision should consider height, loads, soil, drainage, access, appearance and surrounding structures.

Send several clear photographs, the property suburb, approximate wall length and height, access information and your preferred wall style.

Also mention drainage problems, an existing wall, boundaries, nearby structures or plans already prepared.

Good photographs and measurements can help with an initial assessment. A site inspection or further information may still be needed to confirm levels, soil, machinery access, excavation, disposal and drainage.

Old-wall removal can be included. The approach depends on the existing material, wall condition, access, disposal and whether nearby soil or structures need protection.

Access affects machinery size, excavation methods, material movement and project time. Include gate width, fences, stairs, sheds and obstacles when sending your enquiry.

Water building up behind a wall can increase pressure on the structure.

Depending on the site, drainage may involve suitable aggregate, geofabric, agricultural pipe and an appropriate discharge location.

Warning signs may include leaning, bulging, widening cracks, moving soil, sinking paving, rotting timber, displaced sleepers or persistent water around the wall.

Avoid standing near a wall that appears unstable and arrange an appropriate assessment.

Sometimes drainage can be improved separately, depending on access, wall condition and what is already behind it.

If the wall has moved or structurally deteriorated, replacement may be more appropriate than drainage-only work.

Requirements can depend on wall height, boundary position, soil, drainage, nearby buildings and loads above the wall.

Requirements should be confirmed with the relevant engineer, council or building authority before construction.

Important factors include wall length and height, material, excavation, access, soil or rock, disposal, drainage, engineering, approvals and finished ground levels.

This is why accurate site information is more useful than a simple price per metre.

Boundary position can affect access, drainage, engineering and approval requirements. The property boundary and relevant responsibilities should be confirmed before construction.

Yes. Excavation, site shaping, access preparation, backfilling and surrounding earthworks can be included in the project scope.

Ground levels, drainage and watering areas can be considered when preparing the property for lawn, irrigation and landscaping.
