Benefits and Features

BENEFITS AND FEATURES

1	Unlike monolithic concrete retaining walls, those constructed using the TERRA FORCE system are easily formed into complex curved shapes (either convex or concave) or into walls in which the upper and lower profiles are continuously changing. The walls have a flexible structure which is aesthetically pleasing, and produces a natural, environmentally friendly look.
2	Terraforce retaining blocks are designed to allow you a choice between round face, (plant supportive) or flush face (smooth or split version) to suit your specific requirements, and they present a closed vertical surface structure that provides maximum amount of soil mass within the wall and prevents backfill spillage, while at the same time offering uninhibited permeability.
3	Superior bearing capacity is provided by double wall thickness of adjoining elements which also means a broad base for substantial block-on-block friction resistance. Flush fitting, horizontal interlock over full width of the structure effectively avoids point loads and performs even when forming relatively sharp convex or concave curves.
4	Vertical interlock in the form of close fitting, insitu, concrete keys provides positive shear resistance at all wall inclinations. Continuous soil core and root systems within the elements provide additional strength. Where further strength is required the engineer may resort to reinforcing the backfill with geogrids or partially/fully filling the units with reinforced concrete. Double row thickness presents another possibility.
5	When the units are filled with soil the constructed mass of the wall is approximately 800 kg/sq.m (S) - 750 kg/sq.m (L13) - 600 kg/sq.m (L18) - 350 kg/sq.m (4x4) which provides a substantial factor of safety with respect to overturning compared to most modular retaining systems.
6	Open horizontal surface structure ensures uninhibited penetration of water and root systems for maximum growth. Optimal rooting conditions prevent plants from becoming pot bound. Vegetation rapidly transforms the block wall into a growing investment.
7	TERRA FORCE walls are not built in a checkerboard fashion and contain no air voids. Evaporation is thus reduced to a minimum. They offer minimal visual impact due to the choice of colours and natural boulder appearance.
