    foundation trench

    Thanks, polystyrene sounds good and simple. Not sure about digging deeper for the foundation depth though, we are talking about a 1.5 m trench then possibly a bit more but I havnt dug down much yet to confirm the depth, any other sugguestions.

    foundation trench

    Hi I am digging a trench for a single storey rear extension. Next door has already got a similiar extension and my foundation will go to within 50mm of theirs, brickwork 150mm. How do I prevent my concrete joining onto their foundations, I have been told to put a board between them, what type of...

    Hard Core

    Yes sorry I mean under the concrete slab floor. I didnt think I would have to smash them up maybe just lie them next to each other. If I have to smash them up I will save the broken half bricks etc as well then.

    Hard Core

    No not porn spam !! I have a question on what can be used as hardcore on a concrete slab floor. I have knocked down some outbuildings to make way for an extension and wondering if I can use the old bricks that are in good condition as hard core. Lay them down side by side ? Does anyone know if...

    Extension party wall

    The architect has not drawn up buildling reg plans yet which is why I am querying it beforehand. Surely I cannot demolish the party wall though ? only the buildings coming off it.

    No hot water pressure

    Problem solved. it did appear like an air block but I had pumped mains pressure through the drain valve so doubted this was the problem. However I went through every compression nut loosening off and testing for flow, a bit messy but so what. I got to one elbow and there was good flow one side...

    No hot water pressure

    Hi everyone. I have just added a larger hot water cylinder, about twice the size of the old one. It is a vented system, does not contain any air blockages but there is practically no flow coming out of the top, it is just a trickle (0.25 litres/minute). Have tested flow up to cylinder feed and...
