Engineering safe and solid gravity walls that keep soil at bay, and support sub-ground level enclosures.


It takes geology, physics, gravity and engineering to create a retaining structure.

It's not always the case that the plot of land for your project is perfectly flat and level, and that's where retaining structures come in. In instances where a development site slopes or is hilly retaining walls contain soil in its place. Making a site safe to build on and creating man-made elevations that give a project character.

No matter where or why you need a retaining wall, our operatives can help design and implement structures that defy gravity, and provide a solid grounding for soil to bear down on. Using complex mathematical equations to arrive at the exact surface area, trench depths, and height, required to make your retaining wall, strong, stable and safe for years to come.

Our retaining structures extend to all types of wall for underground basement or above ground elevation. Taking into account aesthetics and budget to help our clients achieve a result that doesn't just adhere to practical requirements but looks visually pleasing too. From gravity walls and gabions, to sheet piled, cantilever or crib designs. Our operatives provide tailored solutions that align with your vision and adhere to strict European building regulations.
