    We have a detached garage which we are looking to convert to living accommodation. Whilst trenching for utilities we noticed that the damp proof course has been bridged by the concrete slab. This is inside the garage, the external levels are below. Construction is single skin lightweight blocks...

    Help with garden wall bond

    Hi everyone, I'm trying to build a retaining wall for our garden. We have a slope (back to front) of 447mm and I was planning on using hollow concrete blocks (440mm x 215mm x 140mm) so I can use rebar to tie them into the concrete foundation. I'm a wall virgin but I'm keen! My first question...

    Alternating blocks used to intersect external wall. Replace them?

    Hi people, I have started to remove an internal, non-load bearing wall, on the first floor (only the loft above it). Where the internal wall meets the external wall there are staggered blocks that were part of the internal wall. Makes sense; so you couldn't just push the internal wall down, I...

    Load bearing internal wall - Correct construction?

    Hi all, I’ll try to explain the situation. I have a rectangular ground floor room which currently has the joists above it for the first floor removed. I need to add in an internal staircase and so I am in the process of working out how best to construct a wall to section off the stairs and...

    Rebuilding a wall | Blocks on top of bricks

    Hi I need to rebuild an area of rear wall on the rear of our Victorian house due to it bowing at the top. The wall is brick built and I need to take it down by c. 15 brick courses. As the wall will be hidden internally by a rear bedroom and hallway it doesn’t necessarily need to be rebuilt...
