Sika MTC for BMW Midrand

Sika’s high performance products were specified for the completion of BMW’s new office building in Johannesburg contracted to Barrow Construction. Situated on New Road, Midrand, near the N1 National Road, this completely circular structure has become an iconic landmark.

Three products from Sika’s Moisture Triggered Chemistry (MTC) range were specified for the completion of the structure. With their proven technology spanning a track record of over 20 years, Sikalastic-601 BC (Base Coat) and Sikalastic-621 TC (Top Coat) were applied to the exposed concrete flat roof (approximately 900 m2), while Sikafloor-405 was used on all floors in the air-conditioning plant rooms (approximately 300 m2).

Working to a restrictive time schedule, sub-contractors Quake Seal were responsible for the application of the Sika products. After applying Sikalastic-601 BC as a base coat on all the plant room floors, Sikafloor-405 was then applied as a topcoat.

Sikafloor-405 is a one component, pigmented, polyurethane resin coating with moisture-triggered curing. It is highly elastic, with excellent adhesion and its crack-bridging and UV-resistant properties, makes it an ideal waterproofing product for numerous interior and exterior applications. It is abrasion resistant and slip resistant and suitable for coating concrete, cementitious screed substrates as well as tiles.

Challenges experienced during this project included heavy rains for almost an entire month. However, due to the efficacy of Sika’s world-renowned products and a unique timing schedule, the project was completed well within the stipulated time frame.
