Spancrete holds down ‘Criblock’

Spancrete’s “Criblock” retaining walls have been placed on the slopes of the 200-unit government housing project at North Tarouba in South Trinidad. The project, which is nearing completion, was done to ensure that there was no sliding or slippage in the undulating site, between properties. The criblocks are visible from the Solomon Hochoy Highway. As the undulating land is terraced for the individual houses, Criblock walls, about 9ft high, retain the earth from the higher level, and separate each property. 

The walls require no tools, cement mortar or other accessories for construction, and will quickly sprout colourful foliage to beautify the houses and the environment. Contractors NH International chose Criblock with the approval of NHA engineers, because it needed no foundation, was readily available, and workmen picked up the construction technique very quickly, the company said. Spancrete has built walls in Grenada and St Lucia using the criblock technology.
