Whoever decided those chipboard flooring was a good idea should be shot.... I have found if you drill very carefully through the chip board with about a 10mm with a hss drill bit, you can then stick a small camera that you can get pretty cheap down it to see if there are any cables or pipes in the area you want to cut...
Its used because its cheap to buy, fast to lay demensionally stable when glued and nailed creates a very strong structural bracing on engineered flooring joists often made of 8mm hardboard and 2x1
@@steverobinson8170 I get that but its just horrible to try and take up, at least with floorboards its a bit easier, I think fast a cheap is basically the answer just like everything with new houses.

It's complete shite. I have a house built in the late 70s and every single board is loose and squeaking because of 40 years of plumbing and electrical work, tongues have been cut and boards are cut in random places no where near joists. Battens will help but you'll still end up with movement and squeaking. Extremely difficult to replace the boards without having to basically remove everything from the upstairs of the property because all of the walls are built on top of the floorboards. Should be illegal quite honestly...
Personally I would have bored a small hole in a corner outside the foot traffic area and used an endoscope like the Ferret. That way, when I had finished, there wouldn't be a weak spot in high traffic area.
Yep been there, set the depth gauge on the cheap circular saw- gauge moved out came black water nipped through central heating pipes guess I'm not the first or last. Curious as to why you thought there was a joint box under a section of untouched chipboard flooring.
Yep, nicked a CH pipe that's pressed against underside of a board myself ... ruins your day! Debating whether to invest in one of those Bosch D-Tect things that 'can' find pipes and cable - and (supposedly) measure depth.
i live in a studio flat ( quite small) And, the shocking thing is… that, every time i walk on the chipboard floor; in the bed sitting room… the floor creaks & cracks, more or less all over. It’s enough to drive you crazy. I’ve already replaced my tiny hallway with 18mm plywood; which is stronger than chipboard, anyway. But i think, now… the bed sitting room needs to be replaced too; before i can put laminate flooring on top. A lot of work; and an expensive project. Sunday evening 1st October 2023. Southampton England 🏴
My original trade was a joiner the way the hole was cut out and repaired is totally incorrect , never use a multitool you risk hitting cables and pipes beneath , patching the hole in chipboard in that manner is not structurally sound, eventually the patch will give way (chipboard is not a structural material) . Any supporting timbers needs to be fastened to the joists , really need to be 45mmx45mm not lath
Was just thinking the same. It’s a massive problem I see every day that other trades don’t have any appreciation for the other trades they’re messing around with. Should be cut to the next joist. Those battens are no where near strong enough and although matt mentioned 10 screws. It’s only 4 that are doing all the work. By finding the joists and and then adding nogs in at least 3x2 across the gaps you’d get support on all 4 sides. ideally fixed with PU glue as well as structural screws not just 1 1/2” no 8s for fixing backboxes
@@richardbradley7988 I notice this a lot and unfortunately sparks are the worst offenders closely followed by plumbers who think butchering 50mm slots out of joists is acceptable. I also lay a lot of the blame at the designers doors they never have any input from trades until the project starts, often don't follow sensible protocols of construction , all rush rush rush , simple things like lifting floor heights and cross battening (common in other countries) would alleviate many of these issues as would designated access points
I am a retired electrician and I found cutting a circular hole with a router and gently tapping round the cut with a old screwdriver worked well. The screwdriver would clink on pipes and router depth could be set to a safe depth. Also one can cut nice large hole.
@@steverobinson8170 lol ,speak to your structural engineer , you can safely cut a 3rd out of a joist in height in patches without loss of strength. I use this repair method but i always gluw the batten and the flooring (PATCH AND SURROUNDING FLOOR TO THEM) never ever had a failure .
"Safely and carefully" with no PPE for himself, far less the property owner/tenant. I hate to be negative, but I'm astonished at the number of electricians (and tradesmen generally), who still think it's ok to work in a domestic customer environment without dust extraction for their tools. It's not expensive, it makes you more efficient with almost zero sweep up time, creates a great impression with the customer (referrals anyone?), and protects your own health. It's a no brainer imho.
Older Weyroc is 18mm newer flooring sheet goes 22mm so the first cut depth should be around 16-17mm max then you can use a bit of batten to limit the depth of the multi cutter blade to 18mm, not freehand, and as has been said at least 2x2 par from joist to joist or screwed to parallel to the joist.
@@steverobinson8170I know little about these types of jobs but I'm surprised it's not fixed to the joists. Surely with traffic that will eventually begin to give and sag.
Because they started at 20mm to make sure they didn't make contact. It will likely be 18 or 22, so I imagine they knew it was 22 and did 20 just to be sure.

Nice clean job, I've worked with a few sparks and plumbers who should watch this video
Thanks for taking the time to comment 🦾
You can say that again👍
Nice bit of making good. Definitely will add this to the memory bank

Its cheap crap and they could atleast use screws so you can remove it easier, have to chisel around the nails to pull them out 😡

Yeah, if a person weighing 300lb steps on that hole 8 times a day, very soon he will fall into that trip.
Quality video 👍 as usual guys. Thanks Matt

@@dominicdodd9759 Just cut board through at 17mm then run a craft knife around
If anyone has found a good detector for pipes please let me know 😒
Drill a hole in the center of where the patch will be and shove a bent piece of wire down and turn it to feel for snags?

Great comment Duncan and thanks for your input and for watching 👍
as a customer, i agree
Prior to adjusting a circular saw depth alway remove batter or turn off mains

Thanks for commenting
Great video 👍, always bloody plumbers with shady pipe work.😂
🤣👍
Chipboard is either 18 or 22mm. Fein multitool has a depth stop attachment. No guessing depth or feeling that you have not cut a pipe!
I have chipboard in my flat that is 20mm
Nice work, A little over kill on the patch 4 screws would be more than enough..
IMHO depends where. Done that in a bedroom where there's a chance the bed leg could be re-positioned so used four pieces of batten for extra strength.
Not in chipboard over time that patch will fail its in a high traffic area, the chipboard needs to be supported by45mmx45mm fixed to the joists
@@steverobinson8170I know little about these types of jobs but I'm surprised it's not fixed to the joists. Surely with traffic that will eventually begin to give and sag.
Also probably best not to use a multi tool to "see" if there's any pipes. By the time you've found out you've pierced the pipe...
I’ve always wondered how to lift a chipboard floor 👍
Thanks for watching and commenting 👍
So when you don’t know if there might be pipes and cables under the floor how can you risk cutting with power tools
Because they started at 20mm to make sure they didn't make contact. It will likely be 18 or 22, so I imagine they knew it was 22 and did 20 just to be sure.
If you ever lay something over a pipe. Mark out the board ffs, it takes no time to do ane is generally good practice
I always hate drilling or cutting into the unknown
👍🏻
Surely that won’t take the weight of someone treading on it??? Not better to take section out from joist to joist??
You're not lifting a floor, you're just knocking a small service hole
I would not like to step on the square that been popped back in
Typical plumbers notching the top of the joist. 😁 just drill a hole like us electricians do.
How do you slide lengths of copper pipe through joists that are 450mm apart? 😂
@@affy675 Mark the floorboard 'beware pipes below' or something to that nature.
10.6v drill and drive x 2 all day long. 18v for pre drill 🙄
Noice
"Think it's 20mm" is as stupid as saying "it looks like it might be dead"
I've only ever seen 18mm and 22mm
I have 20 mm in my flat ?
I thought it,qas only 18 and 22?
