Have you got a saturated wall and damp issues ? Have you been told to install a French drain? Do you have a French drain that you don’t exactly know where it is, and even if it is actually working?How to install a French drain?
I have seen many of these installed over the years which have cause serious damp issues where water actually ends up ponding around the building, just like a damaged drain.
Watch my video to see my options of French drains.
If you wish to have a sympathetic damp repair in the first instance you need the correct damp diagnosis. This is something I can help especially when it come s to finding the root cause of damp issues. This might involve CCTV drain surveys, leak detection, carbide testing, gravimetric sampling (BRE DIGEST 245) https://www.completepreservation.co.uk/2020/08/30/what-is-bre-digest-245/
This wasn’t pointed out on our building survey, and the damp and drain specialist never mentioned this either. When I put the hose in, it doesn’t come out of the man hole drain either. What do you think is the cause? The wall opposite has been chemical injected 3 times and still wet.
Hi John, it’s probably blocked with silt etc. As discussed in the video I often see issues with installation.
