Often plots with a steep slope deter people from developing them because of the cost and challenges. However, with land becoming scarcer in many areas, there is more focus on using them to create housing and other amenities. Luckily, retaining walls can offer a solution for many sites. We want to have a closer look at them here, including the different types. Then, if you want help from some of the most highly rated architects in London, you can rely on us.

The idea

Interestingly, people have been using different techniques to reinforce soil structures and build on slopes for a long time. Significant developments in concrete blocks and reinforcements were crucial towards the tail end of the 20th century. As a result, the walls could be taller and more robust. They’d be able to effectively support high loads, allowing development of trickier sites. Plus, they could satisfy environmental demands.

One of the key things to remember with retaining walls is you have several different options. Therefore, you can choose the best type for each kind of project.

The best place to start here is to assess the cost and feasibility for projects. It is always a good idea to discuss options with an engineer and manufacturers. They will help you to think about methodology and other important details. Plus, always think about features you want like fences, curves, corners, and steps. If you need help from architects in London, you can trust us.

Types

The most basic type is gravity retaining walls. You design them so their mass can withstand the lateral pressure of the soil. Heavy materials like stone and concrete blocks are the common choice. Typically the design will feature a batter (a gentle lean) rather than being fully upright to provide more stability. This type is generally best for low height projects, around 3m max.

A second option is to take advantage of the soil’s strength to reinforce the retaining wall. You do this by designing the wall and then installing reinforcing elements into the backfill soil. You can achieve really impressive structural integrity, so it is a good option for taller structures. In fact, there are few limits on the heights as long as you design the walls effectively.

Thirdly, you could opt for cantilever walls. They are an interesting choice because they feature a base slab and stem. It works to redirect the load into the foundation. The big advantage is they can save a lot of space. They are also suitable for mid-height applications, up to 5m max.

Next, you could choose embedded retaining walls. They are notable because they save a great deal of space and work very well if you are dealing with soft soils. The key here is to drive steel or vinyl sheet pile or bored pile walls into the ground. Embedding them provides a great level of stability. As a result, they can work for projects up to 10m.
