The below grade aspects of construction can sometimes go overlooked, especially when considering the region you’re building in. For instance, when you think of Doha, Qatar, you don’t think concrete waterproofing is as important as it is. However, the fact is, many projects that are built below grade are deteriorating faster than anticipated because of the hydrostatic water pressure experienced underground.
Diwan Al Emara design house anticipated this reality when designing the B+M+1 Showroom & Office Building in Doha. The design team understood the impact the hydrostatic pressure would have on the below grade concrete, which was designed with isolated footing with a cover slab to be used as a basement parking having a water table above the footing slab. An innovative concrete waterproofing solution was required.
Diwan Al Emara called Kryton Distributor, Al Jaber Structural Protection Co., the experts in concrete waterproofing for Qatar. Using a traditional torch applied bituminous membrane would have made for a complicated and time-consuming application because of the size of the footing. Further, the risk of leaks would increase because of the various joints in the application of the membrane needed to provide a watertight structure. Al Jaber recommended and used 2,500 m3 (88,000 ft3) of Krystol Internal Membrane (KIM) treated concrete as the alternative solution for the isolated footings, grade beam, column neck, base slab, and retaining wall. KIM is not only simple to apply, but eliminates the need to use a costly externally applied membrane.
This solution allowed the project to save time, labor, and final costs. Krystol Waterstop System was used in conjunction with KIM, and Krystol Baricote was used to close the tie-holes of the retaining wall and water retaining structures for as the complete tanking system.
Krystol Bari-Cote is a high-strength crystalline concrete waterproofing top coat used to resurface and repair concrete or masonry.
Krystol Internal Membrane (KIM) is a hydrophilic crystalline admixture used to create permanently waterproof concrete.
The Krystol Waterstop System is used to permanently waterproof concrete construction joints, pipe penetrations, tie holes and control joints. The Krystol Waterstop System works where other waterstops routinely fail. Kryton is the only integral waterproofing company that offers fully integrated concrete waterproofing solutions.
