35 ML Katlehong reservoir

Our precast concrete roof system was used on a 35 ML reservoir construction project in Katlehong on behalf of Ekhurleni Metropolitan Municipality.

It was installed in only 13 days – far exceeding civil contractors, CivCon and QC4 Civils’, initial expectation of allowing 26 weeks for the construction of the columns and roof deck.

The roof structure comprises 3 500m2 of hollow-core slabs, each up to 250mm deep, and they are supported by 16 columns and 18 beams.

A total of 2 000m2 of precast items were installed in as little as eight working days, with the company achieving tolerances of about 20mm at heights of 15m.
