Robust Floor Expansion Joints by Unison Joints

Unison Joints offers a wide range of robust floor expansion joints for a broad range of building-traffic applications. The Australian-owned and operated company continues to establish itself as industry leader in providing innovative and long-lasting building movement joint systems.

Flexible Choices: Robust Floor Expansion Joints

Robust Floor Expansion Joint Systems are either heavy-duty, extra heavy-duty, or designed for use in some type of harsh or high-movement environment. Robust Floor Expansion Joint Systems include FxCH, DzH, ByC, ByD, ByN and SiBy type coverplate systems

Flexo-CH
FxCH is an aluminium-expansion-joint-cover-system with extruded aluminium coverplates. The whole system, is very neat (see photo), with wide extruded/ramped edges for use in concourse areas such as airport terminals, stadium, convention-centre and other concourses. FxCH has a higher profile than other 'robust' Unison systems as it is designed to be integrated with a range of floor finishes including: ceramic tiles, carpet, carpet-tiles, vinyl, painted concrete and other finishes. Standard coverplate widths are 130mm, 165mm, 220mm and 300mm. The coverplates have anti-slip grooves and conform to a P3 (X) rating when tested according to AS4586. This system can be used is seismic applications.

Designer H
Designer-H is a heavy duty floor cover plate system, specially designed to accommodate heavy rolling traffic whilst presenting an aesthetic finish for use in retail and similar environments. Originally designed (and specified) for use in Masters 'bulky-goods' stores, it can facilitate pallet trolleys, forklifts, scissor-lifts and other large slow-moving equipment. Designer H is a low-profile system for integration with polished concrete, exposed aggregate, and sealed concrete. It can also be used with other floor finishes.

Designer-HX is an aluminium-expansion-joint-cover-system. Similarly to the FxCH system, DzHX has ramped edges on its high-span anodised-aluminium coverplates and its base-sections. It is ideal for use in large concourse areas of sealed/polished/painted concrete such as stadiums and is employed for use at the, recently opened, Optus Stadium; DzHX coverplates also have a P3 (X) slip-resistance rating.

Brawny-C
Brawny-C is an extra heavy duty floor to floor EJ system. ByC's square edge provides a smooth transition for heavy-duty, Back-Of-House applications such as stock-rooms. Originally designed to minimize the 'bump' factor for retractable seating on the main-arena floor, at Gold Coast Convention Centre, ByC has been in service, without issue, as a hard-wearing coverplate system, for many years.

Brawny-D
Brawny-D is an extra heavy duty floor-to-floor EJ system with wide span, and the capacity to house (flush) coverplates ranging from 6mm to 15mm thick. These coverplates are manufactured from 5083 marine-grade alloy; and designed to carry heavy loads over wide spans. This system is ideal for back-of-house, seismic applications; and can be treated, by bead-blasting, for a P5 (V) rated slip-resistance.

Brawny-N
Brawny-N/Aquo-P: Brawny-N can be supplied with either of 2 Unison watersealing Expansion Joint systems. Aquo-P or Aquo-H. The combination of Brawny-N/Aquo-P is the most advanced roof-top carpark expansion joint system currently in the Australian building products market. Other carpark systems have antiquated thermoplastic seals which have adhesion, and other issues, making for poor intersections and upturns; or have cover-systems, which are too high, and eventually come loose, and clang and bang when cars travers. Unison's Brawny-N/Aquo-P system is 100% watertight even at upturns and crossovers. It is very low-profile (11mm), and can be mounted flush. which is recommended on ramps. The ByN anodised coverplate extrusions have knurled surfaces which rate at P4 when tested to AS4586.

Brawny-N/Aquo-H: For refurbishment of roof-top carparks where surface preparation inside the movement gap is limited or impossible, the combination of Brawny-N/Aquo/H is a proven success. Using Unison's Aquo-H hypalon gland, watersealing is full-proof. Alternative 'hypalon' glands are heat-welded or adhered using substrate-bonding adhesive. These methods can be less than satisfactory. The Unison AquoH has simple solvent-welding methods which provide a, seamless, watertight weld.

Seimax/Brawny
SiBy is a seismic coverplate system designed for use in carparks. SiBy has no centrebars holding the coverplate central. Parking cars often involves 'screwing' the steering wheel, and hence tyres, in different directions at low speed. This screwing effect transfers horizontal loads through the traction in a vehicle tyres. Since seismic coverplates are often larger than a tyres' 'footprint', the total load is often transferred. This can have a detrimental effect on centre-bars. Unison's SiBy system overcomes this issue by designing-out the cbars. The coverplate is fixed on one side, and floating the other. The SiBy also allows plenty of space under, for Unison's waterseals or fireseals.
