Holding the ground
where the land won't.
An earth retaining wall holds back the ground where the land will not hold itself — along embankments, cut faces and approach roads. Our modular L-type units are cast in the yard and stacked on site into a wall that carries load from the day it goes up.
Each unit interlocks with the next, so a wall rises quickly and to a clean, fair-face finish that needs no rendering or cladding. The same M50 standard that goes into our drains goes into the wall that keeps them in place.
A cast-in-place retaining wall ties up formwork and curing time on ground that is often already moving. Precast units arrive finished and stack into a wall that takes load immediately — stabilising the slope far sooner.
A wall that stacks in days and holds the slope from the first unit up.

It retains embankments, road approaches, cut sections and boundaries — anywhere a slope has to be held back cleanly and permanently.
Stacks fast, holds for good.
Interlocking units that carry load from day one and leave a clean face that needs no finishing.
Holds the slope
Keeps embankments and cut faces stable where the ground will not hold itself.
Stacks fast
Interlocking units stack quickly and carry load from the first course up.
Fair-face finish
A clean precast face that needs no rendering or cladding once it is up.
Engineering specifications.
Standard L-type sections for heights of 600–2500 mm — for the prevention of soil erosion, to retain soil near culverts, underpasses and bridges, and to stabilise sloped ground. Customized sizes available for mass quantity.

About the retaining wall.
Common questions on height, design and foundation. For anything project-specific, send us your drawing.
Standard L-type units cover retained heights from 600 mm to 2500 mm. Beyond that we cast to a project-specific design — send us the height and ground conditions and we'll size the section.
The standard range assumes soil at γ = 19 kN/m³, an angle of internal friction of 30°, and a 10 kN/m² overburden, with sliding safety ≥ 1.5 and eccentricity within B/6. If your site differs, we re-check the design.
M50 concrete, RCC reinforced, with a fair-face finish that needs no rendering or cladding once it's up — the same standard that goes into our heavy-duty drains.
Units arrive cured and finished, so they carry load from the first course up. A wall stacks in days and stabilises the slope far sooner than a cast-in-place wall waiting on formwork and curing.
Units include a draining hole, and the detail behind the wall uses a soil-particle stop filter and draft-prevention material so water relieves through the wall instead of building pressure behind it.
Yes — customized sizes are available for mass quantity. Send a drawing with the height, load and base and we'll cast to your exact spec.
Other precast lines.
Every line is cast to the same factory standard.
