thank you very much!

Can any help with this? Is it a problem if I just leave it and put the sand and bricks on? thanks

Thanks a lot, I believe you are right. I thought it is big and it shows in B&Q website but it came with same very fine stuff. However the water is not caused by it since if I dig I can see water is just not drain away below the sub base. The below clay is probably the problem. I believe the water it above the bricks of the crawl space of my sun room. Just do know if I just keep it and put the bricks on, can it cause an issue to the room in long term. It will be no water on the top or the pavement since the water can go away somewhere lower from the pavement, but underneath, it is just blocked I believe.

Hi everyone, I’m currently working on hardening a small area right next to my conservatory wall. It was covered by soil and plants. The total area is about 3–4 m². I dug down roughly 25 cm and found the bottom to be quite firm — it seems mostly compacted sand when it was built. To prepare the base, I first added a layer of larger pebbles (about 3-5 cm thick), then covered that with Type 1 MOT sub-base and compacted it. Now it is still 15cm lower than the pavement. However, after a day of heavy rain, I noticed standing water in several spots — still raining. It looks like the water isn’t draining down through the base, possibly because the ground underneath is already saturated or contains clay. Is this a problem? if I just add more sub-base and sharp sand and pave the bricks at the same level as the existing one, will it cause any problem to the room? GPT is suggesting me install a short French drain by using a perforated pipe and clean gravel) to direct the water away from the house wall. But how far and deep should this be? I don't want to make the project too big. thanks

Can I ask how to add the membrane? Are you talking about the one lying under the stones used for stopping the weeds (Option B in my pic) or the one against the wall (Option A) to protect it from the rainwater? thank you.

Thanks for confirming again, I don't see any drainage close to the wall, but the bottom of the trench (which is around 20cm) is sand, which should be good for the water go away. The trench can be deeper if i dig the sand away i believe. it seems the sand layer is quite deep and shoould be good for water draining, is it necessary to add a membrane or pipe?

indeed it is floor timber, there is a crawl space below the ground floor and the air brick is for venting the crawl space. If no concrete slope, will the water drain to somewhere close to the foundation and the well?

Thank you so much both. Can I ask where the DPC is? Is it just above the air brick? To be honest, i really can't see anything different from other layers of bricks. But i do see a row of small holes on another side of the wall just above the air brick -- about the solution, are we talking about making a concrete slope aginst the wall? or adding a DPM against the wall? the upper of the concrete should be 1 brick lower the air block then?

There are some issues with my phone, please omit this one and see the next, which has a picture.

Hello, the plants and soil around my house outside wall are removed and you can see the brick pavement is around 35cm away from the wall and the trench is ready. After checking online and talk with GPT, I plan to use concrete to make a low slope against the wall to protect it from potential rain water, then add type 1 MOT stone as the base, the white decoration stones are on the top. Can anyone tell is this a good idea? There are two types: pebbles and chippings, which is better for this case? thank you

Yes, plan to add this weekend, actually I only removed half of the water from the system since the group floor water was locked inside the radiator, do I still need the to be added? Since before the leaking has probably have all water replaced by the fresh water

sorry to hear that. All are fine now. thanks

Now everything goes back to normal, no leakage, and one radiator used to not warm now also works perfectly! This is the first time for me and I always worry about the situation can go beyond control and water is everywhere. It gives me confidence and I am sure I can change a radiator next time! Your guys suggestions are so valuable and exact - chatGPT talks a lot if you ask, but many rubbish. When you are up to the north, happy to buy a pint for you! Seriously, if I call someone professional to fix for me, how much I have to pay? Just want to show off to my wife today I saved £xxx for the family!

Just read the manual again, seems this is a standard procedure, it says "When the symbol appears alternately with the flow temperature, the siphon filling program is active. The condensate siphon in the appliance is filled"
