About Us

One of the largest retaining wall projects ever undertaken in South Africa was completed in November 2013 on the site of Cradlestone Mall, a new shopping centre which was constructed for the Sasol Pension Fund by Aveng Grinaker – LTA. Designed as gravity retaining walls by Silvio Ferraris, CEO of concrete retaining block (CRB) manufacturer and CMA member, ReMaCon Products, the walls were built on the site which is situated between the N14 highway and Hendrik Potgieter Drive in Muldersdrift. Just under 2 000m of walls were built including a perimeter wall around the entire site and several walls within the site itself.

The walls were built by CMA contractor member, Friction Retaining Structures in a joint venture with Powergate Construction, working as the sub-contractor for earthworks contractor, Diesel Power and Jodan Construction.

Company Profile

Attention to detail has enabled Powergate to expand its operations by gaining the majority of contracts through referrals. These contracts have ranged from block gravity retaining walls in both the domestic and commercial sectors of the construction industry, in the civils sector of the mining industry and in wetlands rehabilitation in the open cast coal mining industry.

All walls are designed to the strictest standards and during construction are inspected by a competent engineer to ensure that the integrity of the design is not compromised by poor workmanship or materials. Experienced supervision is provided on all contracts both at site management level and hands on team leaders who work in a culture of continuous improvement.

It is this culture of continuous improvement in respect of the key performance indicators of time, cost and quality, which the founding members of the company believe will ensure competitive advantage and lead to a sustainable relationship with its present and future clients.
