iTe Products works closely with world-leading manufacturers to develop products perfectly suited for the local industry.
Focused on developing products specifically for African and third-world conditions, iTe Products works closely with world-leading manufacturers of high tech polymers and adapts the technology provided by these companies to address specific challenges in the local construction industry.
“When it comes to waterproofing, we have identified certain problem areas that contractors encounter when it comes to cement work and have aimed to solve these through the development of our unique cement-based waterproofing compound called SEALiTe,” says Alistair Mac Dougall from iTe Products.
“While there are quite a few cement-based waterproofing products in the South African market, they are all based on older technology, while the technology that accompanies SEALiTe is current European technology that puts it at the forefront of the industry.
“Just being able to apply SEALiTe to damp concrete instead of having to wait for it to dry completely, makes a significant difference,” he explains.
This was illustrated at Kiaat Private Hospital in Nelspruit, where iTe Products together with Combined Flooring installed a moisture barrier system with a self-levelling compound over 3 000m² of flooring. Since the contractor could not waterproof the roof and other parts of the building before the concrete was completely dry, the floors were flooded several times because of rain.
“If we had used a conventional moisture barrier system on the floors, we would have had to redo the entire area, but thankfully it was only necessary to replace about 12m². Both the main contractor and the flooring contractor were very pleased about this,” notes Mac Dougall. “Should they have opted for the SEALiTe system for the waterproofing of the rest of the building, the flooding could even have been prevented.”
He explains that this feature is a result of the company’s experience with waterproofing and refurbishing canals. Since these are the lifelines of farmers, they can’t be shut down for long periods of time and the waterproofing compound needs to be applied as quickly as possible without waiting for the concrete to dry out.
Another challenge often encountered with waterproofing compounds is in the application behind stone cladding on walls. Normally, bitumen is used to coat the brickwork, but this has some limitations, according to Mac Dougall.
One of these is that because bitumen is an oil/solvent-based system, over time, the solvent leaches out of the bitumen and the system becomes brittle, resulting in cracks and allowing rainwater to penetrate the walls of the building, especially on south or west elevations. In addition, the adhesion of bitumen to cement is quite poor.
“The SEALiTe system, in comparison, has got bonding capabilities three to four times better than bitumen, which means that there is almost no chance of delamination where cladding is applied to walls. The obvious advantage is that it is a permanent solution with no risk involved,” he says.
SEALiTe is also totally UV-resistant, which is a great benefit particularly in Africa, and it technically doesn’t need any maintenance, except when experiencing significant structural building movement, which will require an intervention. Owing to its flexibility, SEALiTe can be applied to a membrane that can be applied directly over the system to address such challenges.
“Over the last few years, we have built a reputation for developing high-quality, consistent products and we work very hard to service our customers,” Mac Dougall concludes.
