Frequently asked questions

Clear, honest answers for builders, strata, and property owners.

GEOTECHNICAL & STRUCTURAL SPECIFICATION

Retaining Walls, Fencing & Ground Control (10 Key Answers)

Everything you need to ask before signing a contract. Direct, friendly advice built on years of hands-on experience.

Swipe left / right
01 SOIL & FOUNDATIONS

How do you check soil stability before building a retaining wall?

We review geotechnical reports, test soil load-bearing capacity, and design concrete footings tailored to your site's ground conditions.

02 DRAINAGE CONTROL

How do you stop water pressure from damaging the retaining wall?

We install agricultural subsoil drainage pipes, aggregate backfill, and weep holes to relieve hydrostatic water pressure behind the wall.

03 ENGINEERING & APPROVALS

Do retaining walls and boundary fences require engineering specs or council approval?

Walls over 1 meter or near boundary lines require structural engineering certifications and council DA or CDC approvals, which we fully coordinate.

04 MATERIAL SELECTION

Which material is best: concrete sleepers, masonry blocks, or timber?

Concrete sleepers and core-filled masonry offer 50+ year structural lifespans, while treated timber is cost-effective for lower, non-critical garden tiers.

05 BOUNDARY FENCING

Can boundary fencing be built directly on top of a retaining wall?

Yes. We integrate heavy-duty steel posts or core-drilled sleeves directly into concrete sleeper footings for long-term wind resistance.

06 SLOPE EROSION

How do you handle severe land movement and bank erosion?

We use deep pier bored footings, rock anchoring, and heavy-duty soil reinforcement systems to permanently lock down shifting banks.

07 NEIGHBOUR BOUNDARIES

How do you manage excavation and access near neighbouring properties?

We perform pre-commencement dilapidation reports, establish clear boundary surveys, and protect adjoining structures during excavation.

08 PROJECT TIMELINE

How long does ground excavation and structural wall construction take?

Most residential ground control and wall builds take 1 to 3 weeks depending on site access, rock excavation, and concrete curing stages.

09 STRUCTURAL WARRANTY

What warranty covers ground control and retaining structures?

All structural retaining works are backed by a full statutory 6-year structural warranty and engineered design sign-offs.
