The striking dome of the Nizamiye Masjid mosque in Midrand was waterproofed with Sika’s Sikalastic MTC 12 paint-on roofing system.
The Nizamiye Masjid in Midrand, Gauteng, is the largest mosque complex in the Southern Hemisphere. Its beautifully ornate dome not only stands out in the city’s skyline, but also required a high-performance waterproofing solution, which saw Sika supplying a range of its products.
Because conventional waterproofing was not a viable option for the complex detailing of the dome, Muhammad Mayet Architects & Urban Designers specified Sika’s Sikalastic MTC (Moisture Triggered Chemistry) 12 paint-on roofing system, which meets the stringent international standards.
TDS Waterproofing was contracted to apply the system, comprising Sikalastic-601 BC as the base coat, Sika Reemat Standard and Sikalastic-621 TC as the topcoat.
Sika Reemat Standard is a glass-fibre mat reinforcement for use with Sikalastic-601 BC, and is easy and quick to apply. Adapting to the different shapes and profiles on the substrate surface, it not only ensures the correct thickness, but also enhances the crack-bridging properties of the base coat.
Both Sikalastic products are cold-applied, highly elastic, crack-bridging polyurethane designed to provide easy and quick application. These seamless, waterproofing membranes with their moisture-triggered chemistry have the ability to rapidly become water-resistant. With a strong resistance to atmospheric chemicals, both Sikalastic-601 BC and Sikalastic-621 TC are vapour-permeable and emit minimal odour during application. Sikalastic-621 TC is also ultraviolet (UV) stable.
Despite heavy rains during the application to the dome that caused severe time constraints for the contractor, the total surface area of 150m2 was successfully waterproofed.
The extensive service life provided by the Sikalastic MTC System has given the Islamic Institute a cost-efficient and durable solution for the dome of their majestic mosque.
