There are a wide range of floor waste designs on the market, each with features to suit different applications and installation methods. When selecting floor wastes in projects that require passive fire rating, some consideration should be given to the system’s compatibility and the Passive Fire Protection (PFP) product selected.

The penetration/core hole through the flooring structure should be kept as minimal as possible for fire rating. Easy clean wastes that use a bucket and funnel design are often supplied with shower trays. They provide an excellent solution for squat flooring cavities; however, they do require larger core hole sizes to be cut and have minimal testing for passive fire protection.

In accordance with AS 4072.1-2005, an install scenario that hasn’t been tested can only be used if it is:

approved by the regulatory authority;
permitted in accordance with AS 1530.4; or
formally assessed by a registered testing authority.

As mentioned above, large core holes for easy clean wastes may not have the testing needed for the installation scenario; this would likely result in the slab being reinstated to suit a tested system. Utilising plumbing systems that cater directly to a tested solution streamlines the process by not needing to reinstate oversized core holes.

Trayrite

Selecting products such as Allproof’s Trayrite allows the tray waste system to be converted to a traditional floor waste gully, providing a fully tested passive fire solution for shower trays that can be core holed in one cut and have a drop-in collar or retrofit collar applied to it. An added benefit to a traditional floor waste gully is the reduced maintenance as they are considered self-cleaning – water pressure from modern systems washes away any debris.

When testing PFP products in accordance with AS 1530.4:2014 on floor wastes, a temperature sensor is positioned directly in the centre of the open metallic or plastic grate, or the area with the highest exposure to heat, as the water trap below combusts/melts.

Allproof’s advanced intumescent is able to activate and close the opening before exceeding the temperature allowance on the thermocouple, giving a full FRL result for insulation and integrity that cannot be achieved by most competitors globally.

Allproof cast-in floor waste kits

Allproof has floor waste results for the following flooring systems with a range of PFP products:

Concrete slab
Composite steel tray floors
Rib & timber infill
CLT
Plasterboard ceiling

Designers and installers have taken advantage of Allproof’s fully tested plumbing and PFP systems with projects such as 17/31 Franklyn ST Huntingdale by Halder Plumbing and GCD Plumbing at Caroline Springs Christian College. Both these projects benefitted from the Allproof cast-in floor waste kits providing an excellent drainage solution that’s fully PFP tested with an FRR of up to -/240/240.

Selecting PFP manufacturers that specialise in the systems passing through fire cell penetrations means designers and installers can benefit from fully compatible and innovatively designed solutions. These integrated systems improve the selection, design and installation aspects of both the plumbing and passive fire protection.
