Emseal SJS System
Emseal® SJS System - The Emseal SJS System (Seismic Joint Sealing) is a high performance, horizontal, watertight, wide and / or high movement, expansion joint sealing system with an integral protective cover plate. It is the ideal solution for sealing wide and / or high movement joints in parking areas for vehicular traffic, with the range including systems for all types of traffic from pedestrians to HGV’s, in traffic, parking and hard standing areas. The Emseal SJS System can also accommodate up to 100% (+/- 50%) movement and is normally used for joints from 100 to 400mm wide, though bespoke systems for joints from 50mm to more than 450mm have been produced. The Emseal SJS system, has recently been called the best parking deck movement joint solution for new build car park decks, and the best parking deck movement joint solution for car park 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, as well as meeting any other specific demands, such as fire resistance for example: Then:
- In new parking deck construction works, the need to create concrete edge rebates or box-outs around the joints for embedded flanges, as well as the forms or drilling for mechanical fixings, is very time-consuming and expensive, as well as a clear point of potential weakness and for the onset of corrosion in the future.
- Equally dealing with these aspects of embedded frames or cover plate supports in rebates and fixings, can be very expensive and time consuming on refurbishment projects, with the need to break out and remove whatever remains of the joint system bedding mortar, then to structurally repair, make good and reform these rebated areas.
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 nosing’s, 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.
As with almost all Emseal systems, the Emseal SJS Systems require no mechanical fixings to be used, because they are securely bonded into the structure and their integral cover plate is mounted in the central spline of the system itself. This innovative design also reduces stress transmission to the structure during the whole of the long system service life, as well as eliminating the potential for damage and the early onset of corrosion.
