Waterproofing of new Polokwane reservoir

The 5 080m² concrete roof of the reservoir was waterproofed using the abedex plastomeric polymer-bitumen torch-on membrane which is supplied by a.b.e Construction Chemicals

Roland Chonowitz, technical sales consultant for a.b.e. in Boksburg, says the concrete roof – which is built of hollow-core concrete slabs – was covered with 600 rolls of abedex, 4mm thick.

“abedex is a dual-reinforced torch-on waterproofing membrane. It is manufactured from polymer modified bitumen which has been reinforced with a rot-proof, non-woven polyester fabric and strengthened with a fibreglass mat. On application, the bitumen is dispersed into a continuous polymeric phase.

“The membrane, which is heat welded, provides excellent dimensional stability,” Chonowitz says. “And to make application easier, abedex membranes are covered with evenly distributed fine talc so they are easy to unroll.”

The waterproofing of the Polokwane reservoir was undertaken by a.b.e’s approved specialist waterproofing contractor and flooring applicator, Fibreseal. Fibreseal specialises in torch-on waterproofing on concrete roofs, torch-on boarded systems on low pitched sheet metal roofs, industrial fibreglass applications, and epoxy flooring.

The main contractor for the construction of the Polokwane reservoir was Yarena Civils.

abedex can be used for challenging waterproofing projects such as flat concrete slabs, basement tanking, and metal or timber decks. The product is paintable and provides excellent ageing resistance. It is supplied with a 10-year warranty.
