Retaining Wall FAQs

Why does Secura Grand have two voids in the block?

The voids make the block lighter and easier to lift and construct on site. The voids are also filled with 10mm single size drainage aggregate to provide extra stability and improve drainage.

For more information on our retaining wall support from planning to on-site construction, visit our dedicated Secura retaining wall page for details on how we can assist you at every stage of your Secura project.

What is the degree of set back for Secura Grand?

Secura Grand has a 7 degree set back which is automatically created by the nib as the blocks are stacked.

What is geogrid reinforcement?

Geogrid is a high strength geosynthetic mesh material used to reinforce soils. Geogrids are available in various strengths and come in rolls. For all Secura Retaining walls designed and built to BBA requirements Huesker Fortrac geogrids must be used.

Read our ‘everything you need to know about retaining walls’ blog for more detailed information.

Are there different construction methods for Secura retaining wall blocks?

Secura Lite can only be constructed as a gravity wall. Secura Grand can be constructed as a gravity wall, a reinforced wall or a concrete backfilled wall. See Tobermore’s Secura product page for full details. Construction is made easier thanks to our wide range of retaining wall tools such as Secura Fastfind, Secura Create and Secura Portal.

Contact retainingwalls@tobermore.co.uk if you require more support.

Can I install a fence above above my Secura Grand retaining wall?

Yes. Secura Grand walls can have tall fences – including acoustic fences – installed above them. A consulting engineer should be consulted to detail specific requirements.
