Anyone please?

Hi. I've made an opening for gas meter. I've installed lintel. Do I need cavity tray or damp proofing? Will be in extension that's currently being built from blocks and finish will be K render. Also I would like to go for black hockey stick that goes inside cavity. I know it needs to be...

Do you have a diagram of how that is installed? Will need it for extension window. Cheers

I use 2 buckets of sand and half bucket of cement at a time. I add this to water in flexitub. Quick mix with shovel. Then mix with paddle on drill. Comes out perfect everytime. ;)

You guys are lucky. I don't have a mixer.

Weather has not favored me either. I've had to cover up many times also. Use plasterciser in the mix. Below dpc is 3:1 mix. Above 5:1 is fine but I'm using 4:1 (easier to work out) Don't think you will need wall ties for 1st two courses if you are filling up with concrete but best double check...

I'm 8 blocks above dpc. Are you using trench blocks? As any cavity 225mm below (1 block) needs to be filled with concrete. I used foundation blocks. Normal block one before dpc. Don't forget wall ties. Start at edges to allow insulation to sit. Also air bricks and wall starter kit to tie wall...

Hi. I've used aquapanel in shower area. Cheers

@^woody^ Awesome. Will take on board (y)

@Charlie George Cheers. 15 minutes wow.

Hi. I'm taking too long with my corner work. Filling the blocks in between are easy. I'm cobalt checking that the block is level from all sides then using a small level to check the block itself. Then I'm checking that it's 9 inches in height. I don't have a builders profile. But there must...

What's the reason for pvc on the plasterboard

Hi. I plasterboarded bedroom with ensuite 8 months ago. Didn't get it skimmed right away. The room is heated. My question is how long can a room be boarded before skimming? Would there be need for further measures like pva? Ensuite will be tiled would that require anything additional? Cheers

Thanks. Finally do the calculations apply to internal leaf or external as both would produce different outcomes.

Is it 17mm or 27mm as I mentioned 450mm pillar initially but blocks are 440mm.

What is this 2/3 & 1/3 rule? door opening is 135cm and window will be 150cm wide. Internally the width is 4.27m. 66.7% opening. Does that mean I'm within or out of the rule according to the strict Bco? Outer skin I'm with in. (y)

The pillar is equivalent to single block length. So will stack one block on another. Will use wall ties on each one. How would I achieve extra 17mm. Blocks are 440mm wide. Cheers

Thank you (y)

Hi. I've decided to keep pillar between door and window at 450mm on rear extension. The door is 1300mm. Window is going to be 1500mm wide. My question can the pillar be made of single blocks on one another. Or is it best to cut them in 1/3 and 3/4 and then build like brickwork?. Cheers

I see. I'll just pour 3 to 4 inches of concrete with out dpm. Ive levelled it out with 8 inches of hardcore.
