block

Hi all, Embarking on a small extension on the back of the house. No knocking through required, just using existing window and door openings. I've spoken to BC for some of the technical info, and am intending on doing a chunk of the work myself as much as possible. My questions are as follows...

I’m building a rear extension on my bungalow. The block and beam floor has been designed so that the beams run parallel with the rear facing wall. So i understand that usually if they were running perpendicular, the beams would key into the existing wall and be supported by the load bearing...

Easydrive seem to be a bit shy of providing hole spec.. The 6x100 have 6mm thread diameter, slightly unsurprisingly (with 4.8mm shank). They're going in to a concrete blockwork wall. Is there a general rule for hole sizes? Thank you Dain

After being let down by several structural engineers wondering if anyone on here will be able to help me. I purchased a new house 4 months ago and the garage is my next project. Water has been getting in for several years and it has rotted the existing suspended floor rendering it useless...

Can anyone help with a solution to a partially blocked toilet? This has never happened before and has only just started. Basically the toilet flushes fine, and maybe the fresh water after a flush takes a little longer to settle at the correct height. But after a few hours left alone, brown...

Hi I am doing the block work on my extension and I'm wondering the best way to continue around the ground floor windows. I can run a full course of 75mm blocks on top of my wall now which leaves me at the correct height for the window and then the coursing is also correct for the lintel, or I...

Hi I am doing an extension and had a trial hole dug for the foundations which was to 1.4m (deep due to trying to find good ground - point 1 below). The water table was oily/contaminated and ground is obviously made up ground. My council building inspector came out and inspected the hole and...

another of my silly ideas. can i build fence posts using concrete blocks? the blocks would go vertically. their size is 440x215x100mm so if stacked as on the drawing i made, there would be a suitable gap for mortar. the desired height of the post is 2m so 5 layers to stack. please comment...

Early eighties build, inner leaf and inner wall blocks a sort of blue/grey slate colour, not aerated thermalite type (a similar size though). Whilst they're not as hard as modern concrete blocks, they're still quite dense, and they have inclusions, sometimes white, other colours too. What are...

Hi all, is this a ridiculous idea??.... I have a 3.5m x 9m block paved patio in the garden. Its structurally good and hasn't dipped or moved in the 4 years we have lived in our house. My question is: could I directly concrete slab on top of the block paving? I know this sounds a bit odd but it...

Hi all, My ground floor is of beam and block construction with a 150mm or so void underneath. I initially thought it had no airbricks whatsoever although I found out they had simply been covered / blocked by garden soil, patio slabs, etc. I've read that the void needs to be ventilated and my...

Hi all, New to the forum, but I have joined as I have no idea what is going on here. I'm looking to open up a hope between my kitchen and living room, we live in a 1940's council block, the kind with the sash windows and walkway. Obviously want to get permission from the council, and today I...
