Retaining panels

TerraFirm retaining panels can be used for either a stand-alone retaining wall or a fully integrated modular wall, enabling developers and homeowners to incorporate noise prevention and earth retaining functions into a single, seamless wall structure.

Our heavy duty commercial grade TerraFirm XL panel is capable of retaining up to 3.0 metres, whilst bearing a surcharge live load of up to 10kPa.

Because these same modular wall systems accommodate a wide range of acoustic panels, incorporating TerraFirm retaining panels gives the option to create walls that serve as noise barriers and earth retaining structures.

This saves a significant amount of time, money and space by avoiding the need to build a separate retaining wall which occupies a sizeable amount of land. There is no need to enlist a separate team of contractors for a separate building project, while the creation of a single wall that fulfils two purposes maximises usable land space.

Compared to the heavy concrete sleepers that are traditionally used for the creation of retaining walls, the lightweight reinforced composite panel is easy to install, requires far less machinery or labour and occupies much less space.
