    Hi people

    My mate has a problem with his driveway lights keep filling up with water and tripping the RCD

    Anyway we have tried the Raytech gel it worked for a while but he thinks they are filling up from the bottom and the water eventually pushes the raytech gel up and it seeps into the housing.

    I said maybe we can try something else? Does any one have any recommendations?

    He want me to do the job for him so I would like it done right

    Disconnect the supply and cut a new block in the hole. :) problem solved.

    On a more serious note. Pull the lights out. Drill a big hole down into the sub base and fill with pea shingle.
    Give the water somewhere to go. No idea if it will work but worth considering. It shouldn't be holding water anyway if it was excavated to depth and installed correctly.

    Got a pic of the drive.

    i dont have a pic of the drive but it was a pukka job truck loads of type one then re inforcing mesh then concrete then the blocks
    I did think about pulling the lights out and drilling down but the bases are bonded in! and the cable glands are in the bottom decent glands too but you know water

    And what provision was put in to drain the water passing through the blocks to the concrete base.

    Can't understand the trend of laying blocks on concrete.
    @spencer 427 ever seen it done.

    Have done it over drylene. They use to do that on site years ago.

    Also laying blocks over concrete is not a good idea as they will eventually rock loose

    Aye. Still allows some movement and acts like sand screed when it does break down. Should still let water pass too I suppose.

    We used to use granite sand. Wet it up while compacting for similar results.
    Polish lads I worked with on jersey laid on granite chippings and seemed to work well.

    @123hotchef do you know what if any drainage they put in to remove surface water from under the blocks.

    the blocks are sealed after the water runs off to the drain

    RTV silicon? The lights will be a ball ache to remove as they are bonded into the core drilled pavers and the cables look pretty tight too

    With lights installed in a drive there is normally a French drain that takes the water away to a soak away . If no drainage was installed it's going to be a problem

    What IP rating are the lights?

    Ideally, you need IP69K.

    can you open them up and fill them with something else?

    some kind of acrylic/resin?

    I made myself a back light of my electric bike years ago, solcered a load of LEDs onto a circuit board then put it in an old chinese food tub and poured clear resin on top... let is set and job done

    only thing is.... I have no idea what that stuff was called (forgot some things when I fell on my head).... mixed main stuff with a hardener, stirred then poured it on... it set rock hard (and transparent)
