Listed below are contributing to the growing popularity of Terraforce among architects, engineers, developers, contractors and home owners. Terraforce blocks are manufactured under controlled conditions in factories on five continents and may be employed to solve from light erosion control applications to heavy composite earth retaining requirements. Our consultants will gladly share their experience of many years with you to maximise the environmental and aesthetic opportunities that exist on your site.
Hollow core reversible units.
Chose between round face,
(plant supportive) or flush face (smooth or split version) to suit your requirements. Units are light weight for easy delivery, handling and installation, yet heavy in mass when filled with soil, gravel, or concrete. Set fence and handrail posts within blocks.
Unique Horizontal Interlock
With optional vertical interlock allowing for seamless variations of wall inclination (90-35 degrees). Eliminate the use of geogrids in many cases. Convex and concave corners and curves of unrestricted radius allow complex designs to suit site conditions.
DESIGN CHARTS for the smaller units are provided to suit most sites where relatively light retaining walls are required. Where medium to heavy retaining walls are necessary, other Terraforce products are available to provide lasting solutions. Extended applications must be individually designed by a qualified engineer. These will include composite structures with geogrid or cement stabilised backfill, or when double / single row designs are to be combined with reinforced concrete infill. The comprehensive guide to the design of Terraforce L13 retaining walls and the Terraforce design and installation manual for geosynthetic reinforced soil applications will provide the necessary information. (Design Options).
CONSTRUCTION must be carried out in accordance with practical installation guidelines and details as contained in our construction manuals. The units are light and easy to handle before filling. No special construction skills are required.(Installation Guides).
COST EFFECTIVE Terraforce walls may now be turned into a growing investment by your creative choice of plants.
