Modern Earth Contracting designs and builds retaining walls across Adelaide metro, Adelaide Hills, Fleurieu Peninsula, and Murray Lands. Functional, properly engineered walls that manage level changes, protect embankments, and stand up to the conditions of the Adelaide region.
A retaining wall does exactly what the name suggests it retains earth, preventing a slope or embankment from moving to where you do not want it. Done well, a retaining wall creates usable level space from an otherwise awkward slope, protects a building pad or driveway from erosion, and manages the level transitions across a site safely and permanently. Done poorly, it fails, and the consequences can range from a collapsed garden bed to serious structural damage.
Modern Earth Contracting constructs retaining walls for residential and commercial clients across Adelaide metro, Adelaide Hills, Fleurieu Peninsula, and Murray Lands. As a civil and earthworks contractor, retaining wall work is a natural part of our scope particularly on sites where cut and fill has created level changes that need to be managed permanently.
Modern Earth Contracting builds retaining walls suited to the specific application, site conditions, and retained height involved. Common retaining wall types we construct include:
In South Australia, retaining walls over a certain height may require engineering design and council approval depending on the location and what is above or below the wall. Modern Earth Contracting can advise on the requirements that apply to your specific situation and, where engineering is required, work from a structural engineer’s design to construct the wall to specification.
Retaining walls that fail are often walls that were built without adequate drainage behind them. Hydrostatic pressure from water building up in saturated fill is one of the most common causes of retaining wall failure. Every retaining wall Modern Earth Contracting constructs includes appropriate drainage provision agricultural pipe, drainage aggregate, and weep holes as required for the wall type and retained height.
The Adelaide Hills and Fleurieu Peninsula present some of the most challenging terrain for retaining work in the region. Steep grades, rocky ground, expansive clay soils, and high rainfall in winter all affect how retaining walls need to be designed and built in these areas. Modern Earth Contracting understands the local conditions and approaches retaining work in these areas accordingly.
For rural and semi-rural properties, retaining walls are often part of a broader site development scope that also includes cut and fill, drainage, and driveway and access track construction. We are experienced at coordinating these scopes as part of a single project.
