    Socket connected to lighting ring - get rid or OK to label as 5A?

    Our porch has a cable dangling out through the ceiling straight into a twin socket four inches down, and then a cable from this down the wall through UPVC conduit to a switch which supplies the outside light through the exterior wall. This comes off the the whole-house lighting ring which is fed...

    Rosemary tiles 5mm difference in length - cut or match?

    I'm installing a plain clay Rosemary tile roof & the tiles are remarkably different in length - 265 to 270mm approx. I note that this is about the stated tolerance of the tiles, but what approaches do folk take to compensate? Do you take the time to match the tiles (which I'm finding necessary...

    Poly drainage channel in concrete slab - before or after pour

    Thanks for the responses & I'm glad it's led to discussion as it suggests it's not as simple/daft a question as I thought it might be! Not at all surprised that people have their preferred methods all leading to the same eventual outcome. As per Bernard's suggestion, it makes sense to create a...

    Poly drainage channel in concrete slab - before or after pour

    Now, I see your point, but that's interesting, because I'd wondered that leaving it until later when the plan of the workshop had been fully marked out on the slab might be the preferred approach. I guess there's probably opinions out there, hopefully the voice of experience will appear! Oh...

Is it ever customary to try and incorporate a channel for this prior to pouring the slab, or is it better to retrofit once the concrete has...

    Outdoor concrete slab - expansion/contraction slots or side insulation recommended?

    I'm about to pour a 4m x 8m x 150mm slab between a C-shape plan reinforced block wall. I'll be using a DPM on top of the hardcore and reinforcement fabric within the slab. Should I be considering expansion or contraction slots for a slab this size, or would anything else at the side of the slab...

    DPM under concrete when shed will have bearers sat on their own DPM

    I'm about to pour a slab for a 6m x 3m shed. Planning on at least a 4-6" slab (3.5m^3 - I'm buying the beers for a few mates!) as the shed will have a tiled roof & a few hefty machines, but the ground underneath is very, very solid. The shed will have a base sat upon 3" treated bearers, which I...
