EARTHMOVING

INTRODUCING STATE-OF-THE-ART COMPACTORS TO SOUTH AFRICA I CON Group has introduced a series of new exclusive machinery to the South African construction industry, including state of the art new impact compactors, which not only provide superior compaction capability, but also assists in cutting compaction costs and contract programme time. “Our new three- and five-sided impact compactors have impressive capabilities, all being developed to the highest specifications and quality, ensuring reliability and maximum availability on site,” says Wayne Neary, MD at ICON Group. He explains that the three-sided impact compactor is generally used for the compaction of in-situ material on sites where deep compaction is required. Because the depth of influence of an impact compactor is significantly greater than that of conventional equipment, use of this compactor usually makes it possible to satisfactorily compact soil from the surface instead of having to remove the soil and replace it in layers as would be the case with vibro rollers. Depending on the material type, in-situ material can be improved to an impressive depth of 3 m and more. On many construction sites globally, the three-sided impact compactor has been the only technology of its kind that

could achieve the required densities by compacting the site surface without having to remove and replace the material in layers, which has assisted in ensuring considerable cost savings. The three-sided compactor is also used on fill where there is an advantage in placing very thick layers. According to Neary, the five-sided impact compactor is a more general-purpose compactor and is mainly used on earthworks where use of this technology makes it possible to place material in thick layers. Depending on the material type, fill can be placed in layers 500 mm to 700 mm thick and more. This gives the 5-sided compactor an output of about 2 000 m³ per hour compared to the output of a vibro roller of about 300 m³ per hour. The 5-sided compactor is also used on in situ material on sites where only moderately deep compaction is required. Icon Group is a trusted provider of bulk earthworks, demolitions and civil engineering construction services that are needed to get a commercial, industrial or mining site into an ideal state of build readiness. Subject to requirements, we can provide a complete, end-to-end solution, or render each of our services independently. 
