Retaining Walls with Terra-Lock

Our Terra-Lock range is a ground anchoring system ideal for fast and cost-effective retaining wall reinforcement.

Terra-Lock Ground Anchors offer a fast, efficient way to stabilise and reinforce retaining walls.

Retaining walls play a vital role in stabilising sloped ground to create flat, usable spaces whilst also protecting infrastructure like highways, rail lines or other structures from landslides and subsidence. To improve performance and load capacity, ground anchors are often installed to support these walls.

Our Terra-Lock® Ground Anchors provide a smarter approach to building and remediating Retaining Walls. Driven into drilled points and secured with a surface plate, they use soil mechanics to create a strong, stable bond by anchoring the soil beyond the failure plane. For new structures, our ground anchors streamline the required materials, and for existing walls, the method delivers immediate retaining walls strengthening, without the high costs of a full rebuild.

Use Terra-Lock® for versatility within Retaining Wall projects:

  • New retaining wall construction, enabling lighter wall builds
  • Retrofitting projects, bolstering capacity and preventing failure
  • Sheet piling reinforcement, where traditional access is limited

Our innovative ground anchors and retaining wall tie backs have unique benefits such as, eliminating the need for costly rebuilds and heavy groundworks, an increased load capacity and avoiding collateral damage on site.

All our anchoring products such as Terra-Lock are manufactured in the UK with corrosion resistant materials, ensuring the highest standards for your project. They offer speed, safety, and flexibility, all backed by our robust in-house quality and testing processes.

Frequently Asked Questions

Retaining wall anchors transfer wall loads into stable soil. Our Terra-Lock anchors are driven in and locked with a surface plate, this grips soil beyond the failure plane for immediate support.

Yes. It retrofits failing walls without needing a full rebuild, instantly restoring strength whilst cutting costs and downtime.

Traditional tie‑backs need heavy excavation and machinery. Terra Lock installs with simple hand tools, no pre‑groundworks, and delivers faster, low‑impact reinforcement.

Yes. Its slim drive‑in anchors fit tight spaces and strengthen sheet piles with minimal disruption.

Up to 32 kN pull‑out force (soil‑dependent), which is enough for a variety of sites such as; gabion, concrete, timber and sheet‑pile walls.

Our anchors can be installed within minutes using hand tools, so entire wall sections are reinforced far faster than traditional methods.

We are happy to provide, in‑house geotechnical advice, on‑site training, anchor testing and installation guidance from our expert engineers.
