dpc

Hi I will be using periscope vents to air under a block and beam floor and wondered about the below ground cavity fill. All the regs say to fill the cavity to 225mm below DPC although this will partly encase the vents in said concrete; is that okay? Also when I am at DPC the building inspector...

Hi It seems i'm trying for the record of the longest time taken to do an extension! I am hitting so many problems! After much advice & discussion with several structural engineers and the recommendation of the building officer, I am having the foundations for my two storey extension piled...

To the left is the extension, on the right at 90deg to this is the original house wall. To the right of the patio door is next doors garden wall, running parallel with the extension. I have removed the existing concrete slab, which was less than 150mm below dcp level. We had no issues stepping...

Hi All, I have just bought an old 2 story singleskin (no cavity) mid-terraced house that has suspended wooden floors throughout. Ive been hacking away at the ungodly amount of renovations that need doing and come across one that has me stumped... A more recent extension has been built running...

Ramp to next door above my DPC.

Hi Folks, My bathroom floor has had problems with damp and thinking that it was just condensation I pulled the Lino back to reveal pipes in the floor had been leaking. What is worse is whoever installed these pipes had also cut a hole in the DPC for the waste for the bath and never sealed...

Hi, I had a minor disaster yesterday when I hired a power float. I was using the power float on a single garage slab which was surrounded by a double three course wall on three sides. On one of the walls the power float must have hit the wall too many times and shifted the wall out by 1cm...

There are gaps in the concrete floor just inside the front door of my house - and a pale blue sheet of plastic (which is, I suppose, a damp-proof course) is by no means intact. Here is an overview: The size of the gaps is shown by the two pound coin that can (just) be seen in the next three...

Hi, hope you can advise... i purchase my c1900 flat and during bathroom renovation i discovered low down damp which i presume if rising damp. I'm looking at DPC'ing this with DryZone, any good? Also from the pics, i've taken the plaster off down to the red bricks, they are quite brittle so is...

Hi, My son has just bought a new build home and moved-in in December. Since that time the bricks at the back of the house, only, have been permanently wet up to DPC level. The DPC appears to be holding the line and doing its job, though the bricks below are already looking very salty. My...

My late father had a conservatory built in may last year, I'm now the owner of the house my dpc level on the back of the conservatory goes well below 150mm I've been in contact with the company that built it and they said it's because of the flags and I need an aco drain. BUT they put the flags...

Hi all, I have lived in my a 1950's semi for 20 years and finally decided to investigate the cause of the small patches on walls and raised carpet. No mould, just shading of a few places on walls that haven't really changed in the years but as I decorated at the beginning of the year with a...

Hi all, I’m currently self-building an extension to my property. I’m adding an 8m x 6m single storey extension with steel work to possibly take a second storey in the future (when I win the lotto!) I’m wondering can I put the concrete floor slab, insulation and screed in once the roof is on...

Hello. I am hoping someone can advise me. I am fitting a [Wickes] uPVC window into my garage wall. It is a single skin red brick wall and I have opened up the wall and fitted a lintel. All ok. Question: Do I need to add a Damp Proof Course and, if so, where and how? The DPC at the foot of...

I want to convert an attached garage into a utility room, having done quite abit of research on the forum and else where online. I wanted a few peoples opinions/thoughts on it if possible. Being a new build I can only presume that it will have been built with cavity trays in place, so am I...

Hi everyone First time buyer here who is keen to listen and learn from the experienced people. About 8 months ago we bought a 1930's end of terrace property. Since then we have noticed a significant issue with 'rising damp' and as such we have some dry-rot in the floor joists and floor boards...

Hi there, Help please, I am building a one metre wide gravel path alongside my house. Does it all need to be 2 bricks below the DPC? I have hit really tough ground and am struggling to dig it down any further. Hoping I can get away without but still want to do the right thing! Many thanks...

I have a 1880 Terraced House and around the fireplace in the back room (it's closed off) I've noticed a very slight dark line appearing about 30-50cms above the floor. I think this could be the start of rising damp so I've removed the skirting board and the plaster is in good condition (i.e...
