The Emseal SJS System is a trafficable high performance, horizontal, watertight, wide and/ or high movement, structural expansion joint sealing system with an integral protective cover plate.
Emseal SJS System is most commonly used for securely sealing the exposed structural expansion/ movement joints in trafficked areas of multi-story car park decks, including the difficult ramp joints. This includes the top deck joints that are most exposed to the elements and have the highest potential for movement due to the temperature fluctuations with simultaneous dynamic movement from vehicular traffic.
The Emseal SJS system is also particularly suitable for sealing the wide and/ or high movement, structural expansion joints in podium decks and the wide joints in and around stadium bowls etc.
The Emseal SJS System is a trafficable high performance, horizontal, watertight, wide and/ or high movement, structural expansion joint sealing system with an integral protective cover plate.
The Emseal SJS System requires no potentially damaging mechanical fixings into the structure, as it is bonded in position with structural epoxy adhesive. It is installed from one side only e.g. above, which means there is no access required below, as well as no disruption of other trades that may be working below. This makes it the ideal solution for sealing wide and/ or high movement joints in multi-storey car parks and trafficked decks over other areas, such as those over residential and commercial units and storage facilities etc., with access for parking or deliveries, including by HGV's.
The Emseal SJS System will accommodate up to 100% (+/- 50%) joint width movement, and is normally used for joints from 100 to 400 mm wide, though bespoke systems for joints from 50 mm to more than 450 mm have been produced. The Emseal SJS system has often been called the best parking deck movement joint sealing solution for new build car park decks, and the best parking deck movement joint sealing solution for car park deck joint refurbishment works. This is a very unusual accolade as frequently the requirements of new construction and refurbishment projects can seem to be almost diametrically opposed. However, as the end performance and durability requirements are similar, in that the installed joint systems must accommodate the anticipated movement and traffic, whilst maintaining a continuous watertight seal, and meeting any other specific demands on the joints for that project, such as fire resistance for example:
This is just one of the key reasons that the Emseal SJS Systems are increasingly selected for these demanding car park deck expansion joint sealing applications. The Emseal SJS systems provide unique solutions that are fast and cost effective to install on both new and refurbishment projects, because there are absolutely no expensive box-outs or rebated areas to be formed and no mechanical fixings are required. As a result, during new construction the adjacent reinforced concrete deck slabs can be cast, and both sides made square and level far more easily. In refurbishment situations there are no rebates to be cut into existing and otherwise sound concrete, steel or resin mortar nosings, the joint edges/ arisses, simply need to be made good, all saving very significant time and cost over any other deck expansion joint sealing systems on the market, worldwide.
The Emseal SJS Systems require no potentially damaging mechanical fixings, because they are securely bonded into position with structural epoxy adhesive, then the integral cover plate is mounted in the central spline of the system itself. This innovative design also eliminates any stress transmission to the structure right throughout the long service life of the systems. No mechanical fixings also removes the risk of stress cracking in the concrete substrates, as well as the potential for concrete damage and spalling from the early onset of corrosion.
