Under-deck patio lighting


Hi All,

I currently have a raised deck above a stamped concrete patio. In the near future I am going to waterproof the underside of the deck using EPDM as shown in the attached diagram .

I would like to add some lights (low-profile would be best) to the ceiling once it is dried in, but because of the membrane there is very little room for wiring, cans etc. Does anyone have any suggestions as the best way to approach this? This is already an exterior light wired to an interior switch by the door that leads out to the patio if that is going to help.

Regards
Chris

I would do something with low voltage and surface mounted fixtures. The low voltage wire could be run above the ceiling and below the membrane and no electrical boxes would be needed.

Take a look at some marine catalogs. They will have some nice lighting alternatives for boat decking, docks and so forth that should be adaptable.

A belated thanks for the replies. I think I will probably look at regular outdoor lighting, purely due to the costs involved with the LV.

Cheers
Chris

I'm curious as to how you drain the water that goes through the top deck boards and will eventually rest on top of the EDPM membrane?

Hi Bob,

At the ledger board the EPDM membrane will be flat, the droop shown in the image will gradually increase as you get further from the house. Each panel between the joists is kinda fan-shaped to create this gradual droopiness.

This should give me a gradient of about 1/8" per foot of distance from the ledger board, but this could be increased by increasing the height of the compression strips (trading-off headroom, but I'm no basketball player so it wouldn't be distastrous), if anyone thinks that this is insufficient gradient.

Cheers
Chris

I assume the floor joists run perpendicular to the house?

Actually LV lighting is pretty cheap.
