First consider why you have got dry rot in the bathroom and the most logical answer to this is long term undetected plumbing leaks. I would even question whether it is dry rot given the location, are you sure it's not wet rot? Have you seen any signs whatsoever that dry rot is active? Wet and...

The penny drops.

I'm your worst nightmare, a suit who also gets his hands dirty! Where on earth did you learn to treat dry rot because not having a pop m8 but you don't know what you're talking about. You're obviously in the business of charging customers for high priced chemicals that they don't need. Treating...

No, I've been very clear on the point. The CT is a third line of defence in dealing with water ingress at the parapet head but let's not forget that moisture can get into the parapet cavity by penetrating through the masonry or by interstitial condensation and on those occasions the CT is the...

Don't agree with this at all; the problem is that we've lost the knowledge to adequately construct a parapet wall. The vast majority of builders just don't know how to build them anymore. 100 years ago when they were common place everyone knew how to build them. So it's not a matter of designing...

Which regulations were you referring to then Pinenot, I'll wait with baited breath or your answer? I'm very clear in my post that the building regs requirement for resistance to moisture has got nothing to do with rising damp and in fact rising damp is not mentioned anywhere in the building...

You're disagreeing with one of my points on the basis that maybe the OP meant something else. Maybe he meant skip the render or plaster... Genius, don't know about you but I always like to keep the old plaster and render that I hack off, it looks lovely scattered over the flower beds. Or maybe...

I've read two of his posts Woody and the blokes dangerous. More worrying is that people on here are taking his advice! :shock:

Hack out brickwork? Ridiculous idea! Run dehumidifier until moisture content is 10%. What moisture content? 10% is high for brickwork and very low for sub floor timbers. Skip what DPC? No mention of DPC and the idea that you can sterilise for dry rot by throwing everything into a skip is...

There are a couple of obvious questions to ask, the first and most obvious being, is it a ground floor bathroom? If not then I don't really understand all the talk of chemical DPC's. that being said I don't understand why you would use it anyway. Lets discuss the dry rot first. There have...

Err, sorry but he isn't. I've never read such a lot of tosh in my life and you'd be very unwise to follow his recommendations.

Hi, yes, the pics are much better. Ok, the first and very obvious construction detail fault is that the DPC is not supported across the cavity so it is sagging into the cavity and will therefore shed water into the cavity if it bypasses the copings. Ideally you need to bridge the cavity with...

Oh, and I challenge you to find a link online for British rising damp regulations (assuming you mean building regulations). British building regulations make no reference to rising damp. Approved document C, section 5.2, states that walls should: resist the passage of moisture from the ground to...

Seriously, if I understood what you were actually saying then I'd comment but most of what you have written is incoherent and you appear to be conveniently changing your stance of certain factors. The height of the water table is of course a factor when considering the causes of rising damp, it...

Noseall is right!

Thanks very much for the advice everyone. I have seen the lift when I paid for it but its not been delivered yet so I can't have a look in the terminal box. If I struggle I may post a picture when it gets delivers in a couple of weeks.

Thanks Adrian. That was not a problem I even knew I had, the motor is 3 phase, 380v 50hz. I wasn't really enquiring about the inverter but it sounds like a good job you mentioned it. I've no idea what converting the motor to 230v delta is or how to do it. Can you elaborate please? That may...

Construction detailing is everything when it comes to dealing with Parapet walls. I'm a building surveyor and I have very rarely seen them done right. It's difficult to understand what's gone wrong because I can't see the detail but one thing that immediately strikes me is that you made no...

Hi all, I'd appreciate some general advice around installing a three phase car lift into my garage at home. My house was fully rewired to 17th Edition about 3 years ago. The garage wasn't wired up because I knew I'd be building a much bigger garage. Anyway this is nearing completion bar...
