Feasibility Study (abr.) into the Hydraulic Applications of Terraforce "G" 150 & "HD" blocks. (cont.)

GENERAL CHARACTERISTICS OF TERRAFORCE BLOCKS

Two types of Terraforce hollow blocks, the Terraforce "G" 150 and the Terraforce "HD", have been investigated for suitability as bank protection of canals, spillways and estuaries. The two blocks are of similar geometric shape (see Figure 1), the "G" type having a mass of 19 kg and the "HD" a mass of 48 kg. The blocks interlock laterally due to their shape, but there is no mechanical interlocking either laterally or vertically. They can be laid in an interlocking flat layer or can be stacked on top of each other to form a steep slope.

Block infill volume = 0.006m³      Block infill volume = 0.022m³

Dimensions and specifications subject to change without notice and TERRAFORCE "HD" is only available in the Cape Province. TERRAFORCE "G" is now known as TERRAFIX 150. Compiled by the Division of Earth, Marine & Atmospheric Science & Technology of CSIR. *
