3 Gabion wall built with Terra Gabions during 1980
Initially an importer and distributor of wiremesh gabions from Spain, Terraforce became involved in the construction of gabion retaining walls and erosion control measures in 1981. This led to the realisation that in many instances gabions are not cost effective or practical. After considering various alternative methods that were known at that time, it was decided to design a more versatile one block system. Gabion wall built with Terra Gabions during 1980

6 Terraforce retaining blocks can be used as part of either a gravity system or as the fascia of a geosynthetic reinforced segmental retaining wall structure or as a fascia for a cement stabilized backfill. Mass Gravity Retaining Walls Gravity retaining walls rely on their self-weight to resist lateral earth pressure, and such walls have been in use for centuries. In a gravity system the Terraforce masonry units can be stacked several courses deep to provide support to the forces imposed by the retained soil; the weight and geometry of the stacked units prevent the constructed wall from sliding on its base or at an intermediate height, toppling over, or rotating out of position.

8 Geosynthetic reinforced soil segmental retaining walls utilize reinforcing sheets of geogrid or suitable woven geotextile which are attached to the fascia and are embedded in a body of engineered fill. The integrated nature of the fascia and the abutting large body of reinforced soil thereby supports the applied earth forces. In this case the 'gravity' component of the retaining wall is provided by the reinforced soil mass acting as a monolithic unit. By virtue of their inherent flexibility, such walls are able to accommodate movement and some settlement without suffering distress. This makes the system particularly suitable for construction on (engineered) filled ground or in areas which may be prone to settlement effects. Also, the cost and difficulty of construction of such retaining walls is minimized as the need to provide full frost wall foundations can be waived in many circumstances.

9 Bi-Annual CMA Awards Terraforce has secured the Premier Bi-annual Award in the retaining category from the Concrete Manufacturers Association in the years 1998, 2000, 2002, 2006 and 2008 as well as winning several National and Regional Awards at each event. Mixed pattern

Since 1986 Terrafix erosion control blocks have proved themselves as a most versatile and environmentally sound product. They were designed to provide a cost effective, flexible lining to protect against wind and water erosion. Recently the new Terracrete Exec. block was added to our range of products. Terracrete is even more cost effective, and can be specified as a hard lawn - drive over for light vehicles, when provided with a well designed subbase. Terracrete has been designed specifically so that it can be installed with ground anchors for application with high water velocities. Both these durable concrete units, in combination with the original shape retaining blocks, may be used in most saline or polluted conditions, interlock laterally and offer a secure yet flexible lining. The products have been specified in applications, designed to charge our dwindling ground water reservoir and to provide a perfect regime for establishing vegetation.

14 Culverts large and small
Segmented concrete products are rapidly gaining in popularity over other methods and in combination with vegetation cover are more durable, versatile and cost effective. From the environmental point of view this combination stands out head and shoulders above other earth retaining methods, such as wood, metal-based materials and rock rip rap.

Smooth round or flat face

28 2) FEATURES AND DETAILS A living wall:
The unique design allows you to make plants a part of your wall. Durability: Concrete will not rot and weaken over time, and no chemical preservatives are required. Mortarless interlocking systems: The units are simply stacked up without mortar to provide a cost effective, do-it-yourself system. Layout flexibility: The half moon interlock easily handles convex and concave curves, and the wall angle can vary from vertical to shallow slopes. You can create steps by reversing the block. Colours and textures: Use the blocks round or flat face for the wall front. Consult your local supplier about available colours.
