a.b.e. Construction Chemicals recently supplied some of its wide range of liquid and torch-on waterproofing membranes for several new projects in various parts of South Africa.
a.b.e., with head office in Boksburg, was formerly part of Chryso Southern Africa which has recently become part of the Saint-Gobain Group.
Among recent structures waterproofed with a.b.e. products were:
* A Clippa warehouse in Pomona, Gauteng;
* An upmarket private residence in Secunda, Mpumalanga;
* Cape Peninsula University of Technology (CPUT) campus in Bellville, Western Cape;
* Nedbank offices in Plattekloof, Cape Town; and
* The Labiance Center apartment block, also in Bellville.
The Clippa warehouse project involved a 1 300m2 roof area which was sealed with a 3mm double-layer torch-on application of a.b.e.’s Index VIS P reinforced plastomeric bitumen polymer waterproofing membrane. The distilled bitumen product was used with Index Fidia MS (mineral slate) 4.5kg/m2 to provide double-layered waterproofing. Index Fidia MS membrane is manufactured from a compound of distilled bitumen and polymers and features excellent stability and durability at extreme temperatures.
a.b.e.’s bituprime was also applied as primer to the Clippa warehouse roof by applicators, Megapascal Contech. The primer is a bituminous solution with petroleum solvents for sealing and priming porous and non-porous surfaces.
The 1 900m2 mineral slate roof of the “designer residence” at Secunda was waterproofed with the same double-layer torch-on membranes by Hydraproof Waterproofing. The company also used a.be.’s bituprime, duraflex and Dowsil 888 and 8123C for additional sealing.
At the CPUT campus in Plattekloof, applicators Masiqkane Construction had to provide waterproofing over an existing torch-on membrane on 1 800m of roofing, using abeproof liquid membrane system with silvakote eco as top coat. abeproof is a rubberised, liquid applied waterproofing membrane that is highly elastic and durable and requires low maintenance. It can be applied on most building substrates and to refurbish existing, new and old bitumen membranes. silvakote eco is a high-performance UV-reflective aluminium coating, ideal as a “green” replacement for liquid applied systems. This reflective top coat eliminates cracking or crazing problems associated with traditional aluminium paints. abeproof primer was also used for this project.
abeproof liquid membrane system with abeproof PU eco as the top coat were applied to waterproof 550m2 of box gutters at Nedbank offices in Plattekloof Office Park. abeproof PU eco is a flexible liquid applied water based polyurethane waterproofing membrane which is fast drying with exceptional chemical resistance. It has high elongation, and is non-blistering as well as UV resistant. The product is also ideal for roofs, balconies, decks, as well as waterproofing parapet walls and flashings. The application at Nedbank was handled by Deco Systems and IB Inspections.
Finally, an a.b.e. double-layered torch-on system was also used to waterproof the 700m2 roof of the Labiance Center apartment block in Bellville. A 3mm layer of a.b.e.’s Index Vis P was used with a 4mm overlay of the same product. These reinforced plastomeric bitumen polymer waterproofing membranes are made of distilled bitumen and plastomers. a.b.e.’s bituprime, abeproof liquid membrane, silvakote and silvakote eco were also used to seal the roof by Triangle Consulting.
