Installed with a 55 tonne crane, Portland Hollowcore’s slabs are being supplied in several lengths, widths and depths. Once in place, the slabs are covered in screeds in various depths and then tiled.

According to Portland Hollowcore manager, Petrus Theart, the precast staircase were specifically designed and manufactured for the project.

“The slabs’ smooth soffit surfaces are being used as ceilings and downstand beams were eliminated in the design through the use of steel beams.

“In addition to being the proud supplier of hollow-core, we are supplying a substantial amount of readymix concrete to the De Aan Zicht project. The bulk of the concrete is being used for the raft foundations and is placed with a concrete boom pump. We are also supplying the balance of the projects’ concrete requirements for its other applications.”

De Aan Zicht is Balwin’s most iconic lifestyle centre in the Western Cape and its location gives it a cutting edge. Perched on top of a hill, it affords uninterrupted and panoramic views of Table Mountain, Robben Island Lions Head and the Atlantic Ocean.
