Furthermore the cut joists are only attached to a single piece of perpendicular timber, not a double header. They are also just screwed together, no joist hangers have been used. It seems a miracle that this floor is still in place :shock:

Hi guys, We own a terraced house where the staircase from the ground floor to the basement has been historically moved from the centre to the front of the house. The central wall in the basement has been knocked thru to create an open plan environment and RSJs installed. The joists of the...

No there is definitely not a French drain as you describe, only the presence of ballast and gravel against the back wall instead of soil. I'll try and post some photos later. To categorise the dampness problem we have - This problem is nothing like cellars that have serious damp problems and...

Thanks. The floor is damp proofed concrete using a membrane, so no damp issues with the floor. Some of these tanking system seem very over engineered and more of benefit to people who have basements that flood. Behind the back wall the soil has been dug out and replaced with blast and gravel...

Our Victorian mid terrace house is built into a hill such that the back wall of our kitchen is below ground level, sort of a "part basement" This back wall and perpendicular party walls have been previously dry lined using a "dot and dab" method of adhering plasterboard directly to the brick...

I managed to peel back more of the EPDM membrane really easily. I can't tell what type of adhesive has been used to bond it but it is certainly only one type for sure. There is no border of contact adhesive with a central area of water based. Is there a way to tell the difference between EPDM...

Good idea. The roof is 6m x 3m. I fear it is too big to jack up but I'll certainly consider it if I can get hold of the the acro props.

Thanks. The membrane is fairly new and was laid in the last two years. I've managed to detach a small corner without damaging it. Is it the case that the adhesives only work on unused membranes?

Hey guys, My garage/shed has a flat roof with a EPDM rubber membrane bonded to OSB boards. Unfortunately the dimwit who built the garage built the roof literally flat with no relief whatsoever. As a result water pools for days on the roof and runs off uncontrollably down the sides creating...

Cheers for the debate guys. I'm not an electrician but take a hobbyist interest in understanding the regs. As I suspected things are open to interpretation.

Fair enough. But 2.5mm radial circuits need protection using a 20A MCB?

Just a quick question that I had in my mind I hope someone can answer - The regs permit the connection of one double socket to a 2.5mm ring by means of an unfused single 2.5mm cable. The maximum rating for 2.5mm t+e is 20A. However a double socket is capable of drawing 2x13A=26A if fully...

Sorry to reignite this old thread. Has anyone considered using threadlock/Loctite on the threads of the grub screw in traditional JBs?

Cheers for all your responses guys :-) Despite the lack of long term reliability knowledge I will go for the option of replacing with Hager/Ashley MF boxes. They're not very expensive. I'd definitely kick myself if one of those old traditional boxes develops a dodgy connection after laying the...

I am in the process of laying laminate floor across the whole of one floor in my house. I have lifted several floorboards in order to inspect the services before laying the laminate. I have noted that much of the lighting circuit and 2.5mm ring main is jointed by screw terminal junction boxes...

Thanks. After opening the control panel I can provide an update on the issue. The hot water demand pin moves in and out with ease and activates the microswitch. No probems are apparent there. The annoying wining sound starts when the hot water demand pin retracts and the pump is still running...

We recently moved into a 1890's Victorian terrace with a loft conversion. The loft conversion is very old since the walls and ceiling are lath and plaster. I was drilling some inspection holes through the sloped lath and plaster ceiling only to reveal that the gap between the roofing felt and...

We've recently moved into a house that has a rather old Halstead 'Finest' Gold boiler. After what our plumber told us about the boiler I suspect the 'Finest' part is a bit of an overstatement :D Anyhow, the boiler has two problems - Firstly the boiler makes a high pitch wining sound the...
