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 oneblock system.

Terraforce retaining blocks can beused 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 theirself-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 thestacked units prevent the constructed

wall from sliding on its base or at an

intermediate height, toppling over, or

rotating out of position.

Geosynthetic reinforced soil segmental retainingwalls 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.

1) EROSION CONTROL MEASURES

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 ahard 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.

Segmented concrete products are rapidly gaining in popularity over other methods and incombination 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.
