Sovereign Hey’di System is an internationally renowned water proof tanking system for the protection of structures from moisture. Sovereign Hey’di System is used to waterproof basements and cellars so that they can be turned into dry, habitable rooms. The Sovereign Hey’di System can also be used to keep water from leaking out of structures so can be used to waterproof swimming pools and drinking water tanks. Within the Hey’di System is Antisluphate a salt neutraliser for masonry that is contaminated with ground salts. Barriermortar is a non shrink grout used for filling holes and to provide a concave fillet at internal angles. Sovereign Hey’di K11 powder is mixed with Sovereign SBR Bonding Agent to form a slurry that is applied to prepared masonry. Once cured the Sovereign Hey’di System will resist up to 15 bar (150m head) of water pressure from the negative side. Where active water is penetrating through masonry Sovereign Hey’di Powder X will plug leaks in seconds. Sovereign Hey’di Rapid Mortar is a rapid setting powder that can be used for grouting anchor points and machinery into masonry and concrete and for making fixing though the K11 system. If a basement is in a radon affected area then after waterproofing with Sovereign Hey’di K11 Sovereign Radon Barriercoat can be applied. Radon Barriercoat is a radon proof membrane that also prevents ingress of hydrocarbons, carbon dioxide and is also a moisture vapour barrier. Both the Sovereign Hey’di K11 System and Radon Barriercoat are independently tested and hold current BBA Certificate. Free of charge specifications for the application of K11 and Radon Barriercoat can be provided for each individual contract. Where a vapour barrier is required on floors then Sovereign Epoxy DPM is ideal. This can be used directly on to concrete above ground or on top of Sovereign K11 below ground.
