Hi Guys, I have attached an image of the current iteration for one of the garage walls. The wall length is 5.8 metres. As you can see, there are 2 piers on the left, both are 220mm; they will support the door. The distance from the second pier to the end of the wall is 4270mm. There is a 3rd...

What is the recommended end bearing for a 900mm door and a 2085mm garage door that is only single-story and will have 2 courses of block above it, and a flat roof (8x3 joists, 18mm OSB3, and EPDM). I have read that I will need a min bearing of 150mm but I am not sure how to apply that since I...

We built up to DPC with 100mm blocks, laid down the DPM, and had the concrete slab poured. I am now going to lay 100mm blocks on top of the DPM and need some guidance on how I should proceed. 1. Should I mortar underneath the DPM, or just above it ? 2. How thick does the mortar bed need to be...

Hi Guys What's the best way to limit dust produced from cutting dense concrete blocks ? I've got to cut about 32 pieces and will be using a 9 inch angle grinder. I am thinking of wetting the blocks before cutting them but not sure if that'll help much.

Hi Guys, For dense block work, below and above DPC, what would be the optimal mortar mix for a single skin out-building ? I am contemplating a 1:4 or 1:5 builders sand:cement, but not entirely sure which to pick or why.

Hey Guys Anyone used the 17th edition Wylex NM CUs ? Thinking of grabbing a NM1906 w/ some RCBOs but not sure about vertical space. I like my Hagers, but they can be a little cramped

Hi guys I had my trench pour a few weeks ago, and it went to plan, for the most part. I was checking how level the footing was with an optical level and there is an average variation of the footing by around ~4cm - but there is one section that dips by around 10cm. I did level it on the day...

Hi guys, Anyone know where I can get a decent anti-evaporation/curing membrane to use once the concrete for my slab has been finished ? I won't be screeding, so I need a good strong finish on the slab, but for whatever reason I cannot find many curing membrane products out there. There is...

Hi guys I am in the midst of a garage build, and I know that for hard core one should use rubble that is around >= 20mm. What about concrete paving slabs? I've got quite a lot intact ones (350mm x 350mm x 10mm) sitting around, and it'll be a bit of a waste if I have to dispose of them. I was...

Hey guys I am planning on investing into my first multi-tester. I am thinking of getting a Kewtech KT65 MFT, but I would like to consider other options before finalising. Any other "better" brands out there?

Is it necessary to use sand when laying down/whacking hardcore?
