How to Install Linear Grates

Drainage is governed by Australian Standards, and the drainage in an outdoor situation is a function of the landscape drainage plumbing, the water-proofing, the drain apparatus, and the fall to the drain opening.  Each of these contributors to the drainage in your outdoor area may have a different tradesperson responsible so it is sometimes important that they are all aware of the planned installation technique.

Importantly, your ground should be properly water-proofed with a water-proof membrane in accordance with Australian Standard AS3740 before installing the linear grate channel.  This essentially means any water/moisture under your tiles or bricks will find its way to the drainage plumbing installed by the plumber.  Innovative drainage flanges are now best practice to ensure this sub-floor moisture can exit the drain. They also protect the pipework from debris entering during construction (see the video).  

Stainless steel linear drain grates are designed to sit above the waterproofing of your flooring and simply provide a surface channel for surface water to the drainage plumbing, and they should not be allowed to interrupt the flow and escape of any sub-tile moisture which your water-proofing and drainage system has allowed for.

The diagram below provides an illustration of the typical installation in an indoor setting (bathroom) with a concrete sub-floor - it shows the situation where the water-proof membrane (green) has been laid on top of the screed (left-hand side) and where the membrane has been laid under the screed (right-hand side). This linear grate is suitable for both types of water-proof membrane applications.  Download the installation guide below for installation steps and further installation illustrations for timber floors and various grate positions (against walls, hobs, etc).

How to install a shower grate

It is recommended that the steel tray and outlet do not contact the water-proof membrane, seal the drainage plumbing, or be sealed to the drainage plumbing, so any moisture in the tile bedding/screed can escape.  A build-up of moisture in the screed can ultimately cause dampness/mildew and tiles can dislodge.  See diagram above. 

It is also recommended that the membrane be completed before installing the linear grate.  If the membrane is integrated with the stainless steel linear grate, differences in the expansion and contraction rates of hardened stainless steel vs surrounding building materials can result in the membrane weakening or splitting where it joins the steel.   Your licensed water-proofer can advise you on the best methods for water-proofing your drainage area.
