Cobute has worked on Heriot Rei's latest development in the Foreshore, Cape Town, where a an existing structure was converted from commercial into residential, to home 200 new apartments on the dynamic Adderley Street.

The project, which will be completed in May 2019, creates an attractive investment opportunity with the rental opportunities created by the range of Studio, 1 and 2 bedroom units in the building.
The Cobute precast slab was used to create a mezzanine floor on the first floor of the existing structure; moreover, the duct in-fill slab was installed and cast by GD Construction in the remaining 9 floors of the existing structure. The Cobute slab lightness (97kg/smq) and monolithic connections the system favours became a critical factor so not to overload the existing structure.
The Cobute Precast ribs in position
An unconventional but tested system
Unlike conventional rib and block systems, the Cobute precast slab is an interlocking system that consists of three elements: precast lattice ribs, precast panels and polystyrene blocks. Only minimal shuttering is required when installing it.
Cobute manufactures R.C. precast slabs in thicknesses varying from 150 to 350 mm, in increments of 25 mm for intermediate thickness. When designing different slab heights, only the height of the lattice rib and the thickness and length of the polystyrene blocks will change, without increasing the total amount of concrete needed. The Cobute precast slab ensures its contribution to the thermal insulation of the overall structure; the R Value of the Cobute slab ranges according to the height of the slab, from 0.45 for H220mm to 0.49 for a H250mm slab. The slab holds a Fire Certificate rating of 150 minutes for a 230 mm thick slab.
