Beyond standard retaining

Some sites need more than sleepers.

Tall retaining heights, heavy surcharge loads, poor soil conditions, tight boundaries, water tables, adjacent structures, these are the situations where standard retaining wall systems reach their limits. Complex sites need engineered solutions designed from first principles.

METCON builds engineered retaining structures across Sydney, working with structural and geotechnical engineers to deliver retaining systems matched to the specific conditions of your site. Reinforced concrete, cantilever walls, soil nails, ground anchors, mechanically stabilised earth, whatever the site demands.

Whether it's a basement retaining wall on a harbourside development or a 6-metre cut-and-retain on a steep hillside, we bring the engineering capability and construction experience to solve it properly.

Is this you?

Six situations that need engineered retaining

If any of these sound familiar, it is worth a free site visit. We will tell you straight what your site needs.

Retaining heights over 3 metres

Standard sleeper and timber walls have practical height limits. Tall retaining needs reinforced concrete or anchored systems.

Heavy loads behind the wall

Buildings, driveways, or plant equipment placing surcharge loads on the retained earth require engineered design.

Poor or variable soil conditions

Sandy soils, fill, high water tables, or reactive clays need retaining systems designed for the specific geotechnical conditions.

Tight boundary with no room for batter

When you can't step or batter the wall, you need a vertical retaining system, cantilever, anchored, or propped.

Basement or below-ground construction

Basement walls that retain earth and support structure above need full structural engineering and waterproofing.

Council or certifier requiring structural design

Major retaining works require structural engineering, geotechnical investigation, and certified documentation.

What we build

Engineered solutions for complex sites.

From reinforced concrete cantilevers to ground-anchored systems, we handle the retaining challenges others avoid.

01

Reinforced Concrete Walls

Cast-in-place reinforced concrete retaining walls. L-shaped, T-shaped, and counterfort profiles designed to structural specifications with full waterproofing.

02

Cantilever Walls

Reinforced concrete cantilever walls for significant retaining heights. Engineered base slab and stem with proper reinforcement, drainage, and movement joints.

03

Anchored & Tied-Back Walls

Ground anchors, soil nails, and tie-back systems for deep retaining cuts where conventional gravity walls aren't feasible. Tested and certified anchor loads.

04

Mechanically Stabilised Earth

Geogrid-reinforced earth walls with precast panel or block facing. Cost-effective for tall walls on sites where conventional concrete would be prohibitive.

05

Shotcrete & Soil Nail Walls

Sprayed concrete over soil nails for temporary and permanent retaining in excavations. Rapid installation with progressive engineering verification.

06

Basement Retaining

Below-ground retaining walls for basements, car parks, and underground structures. Integrated waterproofing, structural design, and construction sequencing.

Our process

Designed from first principles.

Every engineered retaining project follows our structured five-step process. No off-the-shelf solutions, every system is designed for your specific site.

Site Investigation

We assess the site conditions, coordinate geotechnical investigation where needed, and gather the data the engineer needs to design the right retaining system.

Structural Design

A structural engineer (with geotechnical input) designs the retaining system, wall type, dimensions, reinforcement, drainage, and construction methodology.

Construction Planning

We develop the detailed construction methodology, staging, temporary works, propping, dewatering, and traffic management. Quoted and scheduled clearly.

Build & Monitor

Our team constructs the retaining system per the engineer's specification. Critical stages are inspected, anchor loads are tested, and everything is documented.

Certification & Handover

Engineer inspects and certifies the completed structure. You receive full documentation, design, test results, photos, and certificates for council and project records.

An engineered solution, not an oversized garden wall.

Structural design, geotechnical coordination, documented construction, and engineer certification. Everything the site demands, properly delivered.

Why choose METCON

Sydney's engineered retaining specialists.

Complex retaining needs a builder who can work at the engineering level. That's what we do. We coordinate engineers, manage construction methodology, and deliver certified retaining structures for the most demanding sites.

Engineering-Led

What our clients say

Rated 5.0 by Sydney clients.

5.0

Real reviews from homeowners, strata and builders.

They handled the DA, the engineer, and the build. We didn't have to chase council once. Massive wall, done in under two weeks.
MSMichael Stavros Vaucluse
Two-tier sleeper wall on a steep slope. Other builders said it was too hard. METCON got it done, engineered and council-approved.
GPGeorge Papadopoulos Epping
Council approval sorted, engineering sorted, wall done in a week. Could not fault the process.

Engineered Walls FAQ

Common questions.

Straight answers from the builder. Anything else, just ask.

How much does a engineered concrete retaining wall cost?

As a rough 2026 guide, engineered concrete walls in Sydney cost around $800 to $1,500+ per square metre. Height, loads and footing depth drive the price. Excavation, drainage, engineering and council fees may be additional. We give you a free, itemised quote after a site visit.

Do I need council approval for this wall?

It depends on the height and location. As a general guide in NSW:

Under 600mmUsually exempt, no approval required.
600mm to 900mmMay need a CDC or DA, depending on your council.
Over 900mmAlmost always a DA, engineering drawings and possibly a geotechnical report.

We check your council's rules and handle the application for you.

When does a wall need to be engineered?

Generally any wall over 600mm, any wall near a boundary or building, and any wall holding up a driveway, pool or structure. We coordinate the structural engineer and certification for you.

How long does it take to build?

A standard residential wall typically takes 3 to 10 working days, depending on length, height, access and whether excavation or engineering is involved. Walls that need council approval can add 4 to 8 weeks for the approval process.
