drainage

The polythene DPM for my wet room will sit beneath layers of insulation and a concrete slab. If the floor gets regularly wet, where will the water go? Presumably it wouldn't be ideal for the concrete and insulation to be waterlogged all the time. Therefore should I leave a few deliberate drain...

Block paving laid Feb of last year. After a few months, noticed water pooling against house. Took 6 months of daily chasing (and changing Google review to negative) for company to come out and fit short drain going to down pipe. The blue circle area has a more noticeable dip (metre stick...

Hello, I bought a new build (yes I know I know, we are both physically disabled and did not have choices) Bungalow that down the side has a steep incline toward the side of the property. As usual asking the developer for help is a non-starter. There is no option to grade away from the...

Not sure if this should be in guttering or gardens but looking for some advice! I have a small front garden - 2m from house to boundary wall. I've been doing some landscaping work involving digging up the old broken concrete paths round the house and discovered that the rainwater downpipe was...

I have a concern about a drain at the front right of our house. This drain was blocked up beyond the U-Bend so I had a guy come and unblock it. I watched the entire process whereby he jetted it to remove the blockage, nothing unusual there. But what he revealed was that the drain is not holding...

Hi DIY not community, I’ve recently installed this Floplast plastic debris gully, which will eventually be connected to the down pipe and was unsure how best to finish it at ground level. The debris gully has been concreted in but I took the surface of the concrete up to ground level and...

When the macerator flushes it causes the water in the traps for the sink and washing machine to spyhon out. I was think of installing something like a anti-syphon p trap for the washing machine and sink. The macerator which I have on the 1st floor. I saw mentions of an AAV, but not sure if I...

I'm planning to put a patio in a small area of our garden that was a dumping ground for the previous owners. I've cleared it up and dug down a fair bit: The wall on the left is a retaining wall holding our sloped lawn up the hill and to the right is the back of our garage. In digging out the...

Hello! I have a second floor terrace with big gaps between the slabs for drainage. Weeds grow there non stop. Last year I bought a compound to grout them but my father in law advise me to leave the gaps to allow drainage so I never ended up using it. The other day I just thought I would sow...

Hi all, questions from a DIY beginner about rainwater drainage. My house is mid terrace, both neighbours either side have rainwater/roof water drainage to a pipe running parallel to the rear of the house. Foul water is all out the front of house. At some point, prior to me buying the house...

I've got these two broken rodding eye points in our garden that I ought to get fixed. I was hoping to just buy new covers for both but it doesn't appear that you can just buy the covers and end up with the whole assembly... I broke the middle of this one above taking down a brick wall. I need...

Hi everyone, Well the weather is looking to be better next week and I'm on leave so planning on doing a bit more landscaping in the garden. I'm going to excavate the bottom part of the garden (bounded by the yellow line in the model). There is a clay paver path to be laid on top of sharp sand...

Hi, Our conservatory is leaking and its proving a challenge to figure out where its coming from. Where the external wall meets the conservatory there is an aluminum drainage channel. It seems to have a join there which I believe is where the leak is happening so I want to fix this first. I'm...
