Installation – Threshold Drain

1.Create a solid level base for the channel with either dry concrete or mortar, allowing approximately 127mm for the overall height from the top of the assembly down.

2.Optional drain connection.Install a 100mm diameter surface water drainage run to the desired location at a suitable depth. 370mm approximately accommodates the channel, the outlet adaptor and a 32mm/40mm drainage adaptor. Safely make a hole in the channel then slide the Outlet Adaptor along with channel to the outlet position and fit both end caps. Position and align the top edge of the channel slightly lower than the nosing on the front of the threshold. Insert the outlet adaptor into the 32mm/40mm drainage adaptor.

3.Fold the flexible side of the thresholddrain onto the Damp Proof Course to collect any water from the drip rebate directing it into the channel. The door threshold can now be fitted. If the door is to be fitted at a later stage, then care must be taken to protect the channel from damage.

4.Form the approach to the entrance by laying the required sub-base up to the channel, leaving sufficient space for the surface finish. Any final adjustments should be made at this time.

5.Either: Lay the paving to finish flush with the top edge of channel; ORAlternatively, the top edge of the channel provides a guide to cast a wet concrete pathway against.

6.Completed installation.

7.Alternative installation. Threshold drain can be positioned after the door is installed. In this situation the flexible strip will need trimming to fit under the threshold supported by a cement mortar fillet forming a smooth curve falling back to the channel. All other aspects of installation, as previously illustrated.

Threshold Drain Product FeaturesJointing SystemThreshold drain simply clips togetherwith the aid of a jointing piece.

MaintenanceThe threshold grid can be detachedfrom the Threshold Drain by carefullylevering out and lifting the grid clear toremove debris. To replace, simplysqueeze the grid and rotate the topbackwards towards the threshold, andslide it down the profiles’ internal angleinto place. Replacement grids areavailable in the event of loss or damageand can be easily cut to size.
