    Drainage installation - advise on layout & components

    Hi guys, Firstly, Hugh I'm not ignoring your previous response, just keen to know more before ordering my hunter drainage. When is it best to use a p-trap gully and when a bottle gully? I would have thought a p-trap would be better to stop any potential sediment ever making its way down...

    3 Final questions about trenches before pouring concrete

    Thanks all. Quick update: After reading a few reviews I bought the Bosch quigo laser level. Hate to sound like the people on the review sites, who prob work for Bosch, but it was perfect for the job. I can really recommend it for any similar job. Comes with a handy bracket that can be...

    3 Final questions about trenches before pouring concrete

    Thanks for all the advise guys, I was reading some reviews about the Bosch Quigo self leveling laser. Def a diy piece of kit and not intended for the professional, but I think it would be a useful affordable piece of equipment in the tool box and is likely to do the what I need. Can get one for...

    3 Final questions about trenches before pouring concrete

    Thanks no seal. R896neo. I see your point, but was just going to buy a 30 pound job, which is simply a traditional level with a laser pointing out. No good? Would my 2 metre level not work by marking each end and moving it along? Trying to save where i can. 180 squid to hire one from hss...

    3 Final questions about trenches before pouring concrete

    Hi guys, Had great advice already from this forum about my trenches, but last few before the concrete gets poured on Friday. 1. The building inspector passed the trenches, but advised I remove all the wet slush before pouring. Did this for a few hrs today, real clay muck that ended up...

    Plastic pipes and copper/brass connectors

    Hi Guys, I need to put a temporary tap outside on my building site. It's my house, so can do what I want. I have used an isolating valve that caps the existing 15mm copper pipe. As the tap may need to move and is in an awkward position, I have bought a length of plastic pipe. Can I simply...

    Drainage installation - advise on layout & components

    Hi Guys, Hoping someone can advise on drainage. Apologies if this should be in the plumbing forum, but seemed more building related. I need to install the new foul and surface drains for my rear extension next week and have been researching and planning for a while now. I also have the...

    Sides of foundation walls collapsing

    Very useful to read that, as this was my task for tomorrow. Big relief this afternoon when the inspector passed my trenches. Also had the 400 bags of clay removed phew.. I did ask him what depth below ground level he would recomend the top of the foundations be. He suggested not going more...

    Digging into semi set concrete

    Wasn't planning to have to break out set concrete, just thought it might have been easy whe still wet, but hard enough not to collapse. Polystyrene? Tell me more. Would I need a large cube the dimensions of the void I'm trying to create? Wouldn't know where to get something like that. I guess...

    Digging into semi set concrete

    I will be having foundations poured this week. Although a will need to shutter ina drain on one side, I also want to have a gully pot and another drain pipe. We are head of run, so these will be nearish to the top of the foundations. Rather than shuttering these in, is it feasible to simply...

    Sides of foundation walls collapsing

    Great idea. Out of interest when you mentioned the pegging and having to dig around them, what do you mean. Assume you're not talking about the pegs and string fro marking out the foundations to be dug?

    Sides of foundation walls collapsing

    Thanks for the response noseal. Feel better having read it, but I did go the whole hog today and spent the best part of 10 hrs removing the collapsed spoil and shuttering and pumping. At leat I know what I have already removed, won't return over the coming days. The shuttering should hold the...

    Sides of foundation walls collapsing

    In addition to e above question, are supporting boards and cross timber supports ever left on the side or foundations when they are poured?

    Sides of foundation walls collapsing

    I finished digging 1m by 0.5m trenches yesterday. Woke up this morning and there is significant collapse on the inside walls. By inside I mean the square we have left against the house for this single storey rear extension. Is this usual? The soil is heavy clay, so seemed stable. There is a lot...

    Top of foundation - depth below ground level

    Thanks. The outside ground is a good 30cm below inside floor level and the house is rendered. The extension will have a few courses of engineered bricks to dpc, but the rest will be blocks and rendered, so there is not much to tie in with visually. The floor will be suspended timber...
