Wanting to make their dream home a reality, homeowners from Secunda, Gauteng, knew that the foundation of their new roof needed to be seamlessly waterproofed first before achieving their desired look.

Sikalastic®-560 for expansion joints

Fastner & Fluid contacted Raj Naidoo, Sika’s distribution sales representative, to assist their client, GSA Development Contractors, on site with specifying the correct waterproofing solution for the newly built concrete flat roof to guarantee a long-term, watertight seal.

The expansion joints of the flat roof needed attention before the roof could be waterproofed. A total of 20 10mm expansion joints had to be sealed before the elastomeric waterproofing system could be applied. All joints were sealed with Sikaflex®-11 FC+.

Fantastic properties

The Sikalastic®-560 waterproofing system is a one-component, premium rubber-like elastomeric waterproofing liquid membrane for both new construction and refurbishment projects. It is ultraviolet (UV) resistant, UV stable and creates a seamless, durable waterproofing membrane with its fantastic crack-bridging properties.

For preparation, the newly sealed joints were sanded down and smoothed. On-site training was done for the contractor’s team to ensure precise application of the waterproofing system.

Glass-fibre-matt reinforcement membrane

After the first coat of Sikalastic®-560, Sika® Reemat Premium – (a glass-fibre-matt reinforcement membrane) was applied on the 300m² roof, along with Sikalastic® liquid-applied membrane systems. Once the reinforcement membrane was completely dry, the roof was sealed with a second coat of Sikalastic®-560.
