Innovative solutions for retaining walls

We are not tied to one system but can provide the most suitable system for a particular scheme

1. Concept Design

Who's involved —

  • Asset owners and developers
  • Consultant engineers and architects

Retain's involvement —

  • Analysis of topographical survey providing details of heights and lengths to be retained. Peculiarly this is a real strength as our experience means that we can quickly and accurately read a contour map and decide on retained height, suitable slope on top of the wall, and implications for loading on the wall from wheel loads etc.
  • Selection of most appropriate system from modular block to Gabions
  • Suggestions on how the overall concept can be modified to reduce need for retention by e.g. moving the houses, sloping gardens, changing orientation of houses
  • Provision of concept drawings
  • Provision of feasibility costs for the Quantity Surveyors

2. Planning

Who's involved —

  • Consultant engineers and architects

Retain's involvement —

4. Detailed Design

Who's involved —

  • Design and Build contractors
  • Consultant engineers and architects

Retain's involvement —
