The DPC is approx 35mm below the top face of the existing screed. It is my intention to tuck the new DPM into the DPC before the insulation and concrete go in.

Thanks Joe. Now pretty much made my mind up to bite the bullet and dig the lot up, and replace with proper concrete solid floor, comprising hardcore, DPM, 100mm Jabfloor insulation and 100mm concrete. Have now also confirmed that the inner walls are on a foundation and not the slab, so I...

Currently refurbishing my sitting room in a 60's built bungalow. I knew the concrete floors in all the rooms were in a poor state, being unlevel and sounding 'hollow' in places. The plan was to strip off the original Marley tiles and lay down self levelling latex. However, after eventually...

Excellent stuff, and very inspirational! Keep the pics coming!

Shytalkz – have e-mailed you the details. Spoke to SE today, and he explained the 'odd' equation... He has used a figure of 5mm as a maximum permissible horizontal deflection at the top of the walls as a result of a vertical loading to the roof structure. Therefore when resolved into this...

Thanks Shytalkz! Just noticed you're local, I'm in the Norwich area.... UDL is 1.7kN/m W1 is 18.1kN, W2 is 46.3kN (equi spaced at 2.1m) The beam in question has been sized at 457x152x52 UB!!! Yeah, as you say for it be a tangent it looks to be a horizontal component... but how's that...

Thanks guys! OK, some more info plus I’ve been thinking a bit more! It’s a bungalow, the extension incorporates an attached garage space and lounge, with an upstairs loft style bedroom. Example: the beam spans the garage space (6.3m), and supports the edge of the 1st floor (2...

Had structural calcs professionally prepared by SE for my extension, but I am concerned that they are extremely OTT. Being an engineer by profession I am in the process of working through them, but am struggling to understand a constraint for beam deflection. I am aware of max deflection for...

One of a few I found from a Google search:- http://www.u-fit.co.uk I have in the past run through the pricing page and they do seem to be very competitive, but I have yet to find any opinions from people that have used them about quality.

Sorry if this is an obvious question, but I get different opinions from people, and I did wonder if it was local authority dependant... Question is, can I connect rain water drainage from gutters into underground soil pipe which is connected to mains sewer? And what ever the answer, is it...

Many thanks, got it now.

I am going to need to re-route my mains water supply from entering into the bathroom at the rear of my 60's built bungalow, into the kitchen at the side. I seem to remember that building regs dictate the main has to be a minimum of 750mm below ground for frost protection reasons. Now as the...

Thanks for the reply, not sure if you have understood me or not... I'm refering to the flat horizontal part at the top of my 'vaulted' ceiling that runs down the length of the room. Either way, your answer suggests it won't be a problem :)

Quick simple question.... I'm preparing drawings for a loft type bedroom, which will have a window in the end gable wall. The pitch of the roof is approx 32 deg, and I will be having a 'feature' window made to follow the pitch of the roof, i.e. a kinda triangle shaped top. However, because I...

Or if you don't want to pay over the odds, by the BernzOmatic one from B&Q or ScrewFix for £39, it's exactly the same torch for about half the price! Oh, and use the blue propane cylinders, plenty hot enough for plumbing.

Once mine was running it also ran fine, it was only once it sat over night that the pump could not generate the head to flow oil into the pump.

Had similar problems a couple of years ago, read this:- http://www.diynot.com/forums/viewtopic.php?t=47722 I'd put money on it being the pump, this was the last thing I tried after checking / changing just about everything else! The drive key in the pump rotors had worn to an extent that...

Many thanks noseall.

Forgive me for asking what is probably a basic question.... As part of a soon to be started extension and alterations to my existing bungalow (built in '62), there will be two new window openings into the existing cavity walls. I would appreciate some insight into the procedure for making the...
