Hello Can anybody identify what type of damp proof course this would be. It just looks like a thicker layer of mortar from the outside.

Hi All, I'm planning to build a summer house at the end of my garden up to the boundary, with rough dimensions of 7.5m x 3.5m, flat warm roof. Plan to use the space all year round as an office though will also house gym equipment and therefore am looking to maximise the head height for over...

Hi there, Just moved into a new house which is an old terraced house built around late 1800s. There is plenty of work to get done on it not least the front rendering. The previous owners provided an invoice for work carried out in 2015 for damp proofing, pointing rendering the front of the...

We have a detached garage which we are looking to convert to living accommodation. Whilst trenching for utilities we noticed that the damp proof course has been bridged by the concrete slab. This is inside the garage, the external levels are below. Construction is single skin lightweight blocks...

Hello, First time forum user, I'm looking for some advice on whether a chemical DPC is necessary. It's a circa 1900 mid terrace house. The survey showed high damp readings on the front external wall and the recommendation is the standard chemical DPC and replastering with a waterproof sand...

Will try to keep this as concise as possible... I'm buying a small victorian terrace (it's Grade II listed). It hasn't been particularly well cared for and has what appears to be significant damp problems in the ground floor front room. It is solid floor construction with no cellar so there...

Hi All! First time post but have been a long time reader of the forum. I bought my first property in 2020 which is a 1970's maisonette which includes a single garage which is one of the middle garages in a row of 4. Last winter and whenever there is heavy rainfall the garage becomes damp as...

Hello all, I need some help and advice: A building control officer has recommended a builder to use 6" high timber frame joists to be used with 100mm insulation inside the frame as the proposed suspended timber frame joist of 4" high isn't strong enough for the underfloor heating, because of...

I am currently renovating my kitchen and am looking for some advice in how to screed over a cavity. A section of the old screed layer has broken up around the edge of the patio door threshold. At the moment, there is a dpm under the patio door overlapping the cavity and meeting the main dpc...

We have just had an extension built and have noticed that our next door neighbours have quite bad damp (albeit under their dpc) however our corner that touches theirs is now becoming damp. Looking at the images our dpc is visible and then disappears closer to their wall. Should this be exposed...

I've lived in my current house for over 20 years now- 1940s semi. I must admit, I never pay close attention to brick work etc, but I know there are no cracks or obvious signs of subsidence. I'm planning on resurfacing my driveway and as part of this, I've had a really good look at the DPC. I...

We’re having our bungalow cladded with Cedral cladding. The cladding can’t go below the DPC and for aesthetic reasons we’d like to paint DPC white - the reddish brick against light grey cladding doesn’t look right to us. Before shelling out for the painting to be done professionally, I’d like...

Does anybody have a diagram or drawing showing how the lower corner of a window sill is constructed, and how the DPC and cavity closers join/overlap to form a waterproof joint? I have recessed windows (i.e. they sit in the middle of the wall), and will be making a sub-sill from creasing tiles...

The building regs say a DPM should be 1200 gauge - but what about DPC? The DPC's you buy in Toolstation and the like seem to be thicker than 1200 gauge, but what is the actual requirement? Could you use a sheet of DPM cut into strips as a DPC? - for example, as a cavity tray above a lintel...

Hi, I'm getting to the end of a renovation and the concrete floor screed has been laid. This is in a rear extension to the kitchen and also a new extension at the front. There is a gap of about 3 inches between the top of the floor and the DPC level, both at the front door and at the back...

Hi all, I hope you are well. I'll try to keep this short. I am building an outbuilding (hopefully to use as an office / gym). The size is approx. 7m by 4m. It is being built on the boundary so within 1m. I plan to build it all of the light breeze blocks (except two rows of bricks at the...

Evening All. This seems to be one of the few topics that the Internet does not contain endless chapter and verse on... and that information that is available is less than clear. I'm talking here about the vertical DPC at the join of a new cavity wall for a house extension to the existing cavity...

Hi there I recently bought my.house which is now showing a lot wrong with, I know I need to get the pointing done and the roof verge but have now discovered the drive drains into the side of the house, the bricks below dpc in one particular spot are saturated but not above, I am worried about...

Does the patio in this picture look ok? There's a strip of gravel between the slabs and the wall, but I think this is above the DPC; anything to be concerned about? I'm not sure where the DPC is tbh, or if having gravel above it is ok.
