1. Dz H - Dz H incorporates a revolutionary design that combines low profile, slim visual width and hidden fixings. This allows for minimal substrate rebating, leaving no visual grout line when applied to polished or trowel-finished concrete. Dz H is compatible with a wide variety of floor finishes, including tiles, polished or trowel-finished concrete, roll-coat epoxy and vinyl. DzH incorporates Unison's unique composite, impellor centrebar. Which results in zero corrosion factor.

2. DzHX - This coverplate system can be employed in a range of applications including carparks. It is a bigger, wider version of the DzH, with a choice of 220mm or 300mm wide coverplates. To take care of corrosion it also employs the composite impellor centrebar. DzHX is supplied in anodised alloy. The coverplate has a P3 (X) slip resistance rating when tested in accordance with AS4586. It has high degrees of movement and is classed as seismic.

3. Dz FTAq - Dz FTAq is specially designed to provide a 100% waterproof seal. The high-movement polyethylene (AqP) foam waterseal is integrated with a flexible rubber tread-piece, negating the use of surface-mount plates. Dz FTAq can be easily installed in stadium-plats and carparks. It is a cost-effective surface cover for AqP waterseal which provides a pedestrian-friendly transition across the flexible seal. The DzFtAq is ideal for lower level carparks.

Aquo Range. The Aquo (Aq) range features watertight expansion joints for both indoor and outdoor applications. Here is a brief overview of Aquo Systems:

1. Aq P - Aq P is made of specially formulated polyethylene foam that uses simple, high-quality welding technology for 100% water tightness. Aq P has UV inhibitors to promote longevity. It is suitable for most types of construction, such as internal and external expansion joint waterproofing in multi-storey and rooftop car parks. AqP is especially suitable for joint sealing in seating plats of Grandstands, and has been employed as such at the Sydney Cricket Ground and WESTADIUM. AqP is compatible with most Unison coverplate and firerating systems depending on the type of application.

2. Aq H - Aq H is a hypalon rubber gland system for waterproofing high-movement expansion joint gaps. The system is designed with holes on each side to assist in anchoring to the surface and transferring load support through to grouted in coverplate systems. AqH is compatible with a number of Unison coverplate and firerating systems which now includes ByN. Check with Unison technical department for details.

Brawny Range. Brawny (By) expansion joints provide support and facility to the heaviest loads of rolling traffic. Here is a brief overview of the Brawny range:

1. By C - By C is designed to accommodate trafficability across movement joints for forklifts, scissor-lifts, pallet trolleys and other bulky service equipment. The extra heavy duty expansion joint system includes a mill-finish alloy cover plate and a coupling system of composite impellor-type centre bars that holds the alloy components together. This coverplate system can also be employed over gaps in carparks.

2. By N - By N harnesses the Aq P design to result in a low-profile cover plate system that is totally waterproof and protected from other harsh conditions. The tapered edges of By N achieve a smooth transition for shopping and pallet trolleys, passenger-vehicles and pedestrians over the movement gap. The cover system is made from 6061 T6 structural grade alloy, and the rubber pad has a 3rd-party engineered minimum compressive strength to support the cantilever alloy profile. ByN can also be integrated with AqH for use in carpark expansion joint refurbishment.
