Warehouse roof waterproofing proves its worthBack

Roof Recon MD Kevin Clark says the company was delighted to find that the performance of its installed waterproofing system surpassed even the company's expectation. "Three years ago, the company repaired 10 000 m2 of warehouse roofing at Consol Glass with its newly developed waterproof roof fixing washers. When the company returned for maintenance repairs three years later, it found that the waterproofing system had provided full protection against leaks and corrosion," states Clark.
He adds that the company can now safely state that the maintenance of its waterproofing system adds up to 30% of the initial installation cost, which offers the customer a 70% saving on all maintenance services every three years.
Clark says the waterproofing system consists of a 36-mm waterproof washer and a polyurethane seal. The seal of the washer is a 20-mm thick polyurethane, bitumen-infused sponge, with improved adhesion, and self-healing properties. In addition, the seal is 100% waterproof when compressed. The seal is indented at the bolt hole of the washer, ensuring a perfect seal over a larger area.
The system is then fastened to the roof using standard ‘top-speed' roof fixing bolts. A waterproof sealing strip is placed between the lap joints of the roof sheets to separate the roof sheets and prevent dust and water entering. Bitumen enclosures are placed on all sides of the polycarb sheets, as the expansion coefficient of the polycarb sheet is four times that of a galvanised roof sheet, which means that polycarb roof sheets need special attention, says Clark.
Clark says he created the Roof Recon system to replace existing methods of waterproofing metal roof sheets. He adds that the Roof Recon system is a more cost-effective and efficient method of waterproofing roof sheeting than the traditional method. The system does not restrict water flow from the roof, is aesthetically more pleasing, and the product has a longer life than other traditional systems in the market.
Nevertheless, Clark notes that it is a long and time-consuming process to launch a new product, such as the Roof Recon system, regardless of the added value the product is able to offer to the industry. However, the company offers the customer a long term solution for the waterproofing of roofs, sourcing the problem prior to repair, and explaining to the customer the method used to resolve the leak, he adds.
Further, Clark says, as the product is new, the installation of the system is critical and full-time supervision is always available, as well as ongoing and on-site training.
Lastly, Clark says the company is able to provide customers with a ten-year guarantee when installing the Roof Recon system.
