Cape Town-based concrete cutting, coring and drilling company Concrete Worm has successfully completed a number of high-profile projects by making use of Diamond Products’ range of solutions to achieve optimal results.
Concrete Worm successfully completed its highly-complex scope of work in extending the entrance at Simonstown Stillwater Harbour by 11 m in 2012, by cutting away sections of large concrete walls – known as caissons – using 135 m of Diamond Products Orange razor wire.
The 11 mm closed loop wire contains 40 diamond beads per metre, and is rotated at 28-m-per-second by a 37 kW 380 V machine. A 360-degree swivelling head allows for horizontal and vertical cutting through thick concrete structures with the wire.
Concrete Worm MD Peter Fink notes that the wire exceeded all expectations. “The razor wire proved to be far more efficient than we had anticipated, which enabled us to cut at an average rate of 3,3 m2-per-hour, as opposed to the industry-standard of approximately 2 m2-per-hour.”
Fink notes that the company recently completed another project in East London using the same diamond wire supplied by Diamond Products, in order to cut a 39-m-high concrete tower building. What’s more, Concrete Worm is currently involved in a project that aims to convert an historic, but uninhabitable building into a museum and shopping centre in Cape Town.
Fink indicates that the company is using the wall saw 800 mm blades by Diamond Products. “The building is not suitable for people to occupy, due to the lack of ventilation. As a result, we are cutting the inside walls to allow for windows and doors to be fitted. The work includes drilling 500 holes in the walls and 1 500 m of saw cutting. We started in early-2014 and expect to finish in late-2016.”
Concrete Worm was established in 1996, and today employs 25 staff members who specialise in all diamond cutting applications for large-scale projects nationwide. Fink adds that the company has relied on the Diamond Products range since its inception.
“Concrete cutting is a highly-specialised field that requires advanced and sophisticated equipment. Over the years, Diamond Products has supplied us with core barrels, diamond wire, and saw blades that assist us in successfully completing our projects to the highest standards of quality,” he says.
Diamond Products director Darryl Gray notes that the company prides itself on its value-added after-sales service offering. “Diamond Products is the only company in the local industry that offers free customer training as part of its after-sales service, thereby providing our customers with a comprehensive solutions package to meet all requirements.”
