    Disaster levelling

    Hi all, looking for advice on how to get around a disaster of a levelling job. Basically we have cracked and slightly hollow sounding levelling compound in a low profile underfloor heating floor. It’s mostly solid as it’s bonded to the castellated panels, but areas sound hollow in places...

    Fine cracks in new plaster - Resilliant Bars

    Hi, I’m just painting a newly plastered ceiling which is 12mm plasterboard on resilliant bars. The bars were installed at 400mm centres and every joint had a bar installed to ensure all edges had support. The joints were all taped up with skrim. It looks like theres a small amount of movement...

    i now have 150mm of well compacted hardcore down in the extension and around 50mm of sand for blinding. Does the sand need to be wackered as well, at the moment I've just levelled it down with a float? Thanks in advance Sam

    Filling cavity below DPC

    Whats the purpose of this exactly? I see that you should slope it away to allow water to run away from the internal wall, but surely it would be better if it just dropped further and soaked away well below the DPC? Thanks in advance Sam

    Wall Starters

    The outside of the existing house is a very corse spar dash (council style) but it's very well bonded and not chance of it coming away. It is painted though. Do I need to remove this where the wall starters will be fixed or can I leave it on, screwing the wall starters to the face of it? I...

    Lintels in foundation for building over

    I've got to build over the set of drains for the rear single story extension I'm building. Been a really tough job getting to good ground (2 metre deep) and the build over paperwork took ages too. So I've got concrete poured and now need to bridge where the drains are. They are about 1000mm...

    Insulating cavity walls advice

    So, the garden currently looks like the Somme. Managed to get a 3/4 tonne digger in over the weekend and if it wasn't for the massive lump of concrete found underground, everything would have gone fairly smoothly! Anyway, I need to shutter off the crater that's left and I've seen some people...

    How close can 2 lintels go together?

    So another question, sorry. The rear extension I am doing was originally going to have a full width knock through, but this is proving to be a bit of a pain in terms of cost etc As it is, we already have two openings in the wall, two lintels. They start at either side of the wall, which is...

The current cavity wall is 6 metres long, with 2 upvc Windows and a door already in place (the door and one window are joined and share the same lintel) Both lintels are...

    cement taking ages to go off!

    As per another thread I started, I have been rendering a wall after damp in my brothers house. Yesterday I put up the first scratch coat, SBR'd the wall first with 2 diluted coats approx 10 - 1 , then proceeded to apply the render. The wall was obviously still very porous as I had to work...
