Would you think if might be OK to use acro props with scaffold board above to suport ceiling joists of a bungalow during external wall knockthrough, without removing the ceiling plasterboard or will the plasterboard compress under the weight of the roof load? Thinking it be safer to rip ceiling plasterboard down and run the scaff board directly under the joists, then do knock through and fit new rsj under the existing wallplate..
This is a good video. What is the plan if you are doing a 12" think wall ? I'm planning on putting two doorways into one ? Max opening would be 5 ft so was going to use 2 strongboys or steel bars and acrow both sides .
Hi Leighton, sorry for the late response. Same setup but your steel needs to be an adequate size to support the 12" brick work. Acow prop and support from both sides, making sure you can negotiate the steel between the acrow props. Hope this information is helpful, regards Rob pilkington Dream Home Renovations.
Hello Stephen. The acrow props should be 900ml apart. The amount of props you use purely depends on the size of the area. Minimum of 2. Thankyou for your message and interest 😊
Hi fella Got a fireplace no lintel.About 115cm wide opening. Should i use a strong boy. The whole thing has sat on a piece of formica since i bought house 25 years ago. Iv proped it with timber at moment.intend putting in lintel. Cheers
Hi Paul, sorry for the late reply. Put the steal in the approximate position before putting acrow props in then insert the strong boys and acrow props, take down wall and lift steal into position. Sometimes if you have the room, you can weave the steal in-between the acrow props. Thank you Rob pilkington Dream home renovations.
namaste, main inglaind mein stok on trent se hoon. veediyo dekhane ke lie dhanyavaad. Hello, I am from Stoke on trent in England. Thankyou for watching the video.
Dont think it's necessary to tighten up that much, more likely to get a hairline crack up the wall above when dropping the acrow if you lift it too much on an extension knock through so you'll end up owing the customer a pointing job
Hi mate, yes so the full knock through including building regulations and structural calculations along with the steals and labour for this particular job with cross steals would cost in the region of £3,800. Thankyou
