Sika helps Mimosa Mall to rise from the ashes

From Sika South Africa (Pty) Ltd.

 Mimosa-mall-SikaDue to a fire incident that occurred on the 8 December 2017 in Mimosa Mall, Bloemfontein, a restoration process was in order. After inspection, Sika  ensured that the best quality products were used for the structural strengthening of the damaged areas.

Restoration

As part of the restoration exercise, Sika CarboDur S512 (600 metres), Sika CarboDur S1014 (800 metres), and Sikadur-30 (79 kits), were specified for the external structural strengthening of the car parks and the roof slabs.  Sika CarboDur plates are pultruded carbon fibre reinforced polymer (CFRP) laminates designed for strengthening of concrete, masonry and steel structures.  The carbon fibre plates were bonded onto the soffit roof slab using Sikadur-30, a primerless structural epoxy adhesive ideal for structural strengthening projects. The application of Sika CarboDur S1014 allowed for the increased load capacity of the floor slabs in the sections where heavier equipment was subsequently installed. 

Sika’s high performance SikaGrout-212 was applied under all new precast concrete barriers. This fluid grout provides adjustable consistency, rapid strength development and high final strengths.

The building’s structural support columns were wrapped with SikaWrap-600 C, a unidirectional stitched, non-woven heavy carbon fibre fabric with mid-range strengths.

Time constraints

The time constraints of the construction program were challenging due to the urgency of getting the mall fully operational in a short space of time after the fire had caused such widespread damage. The contractors, WSP Engineers, managed to complete the project in January 2019.

The excellent strength and durability of the Sika CarboDur structural strengthening products made them an ideal choice for this application, confirming that Sika has the correct solution for even complex and challenging projects.
