Welcome, my name is XXXXX XXXXX I will do my best to help you with your issue
It sounds like you would benefit from a french drain around the perimeter of your house. To make a french drain you would dig a trench about 3' away from the house and about 2' deep then lay crushed stone in the bottom of the trench about 6" deep
next lay 4" perforated pipe (with the holes on both sides at the horizontal median) starting at the highest point slope this pipe at ~1/4" to 1/2" per foot towards the down slope
next cover the pipe with landscape fabric then 6" of crushed stone then another layer of fabric then dirt excavated from the trench on top. Throw some of the extra dirt in the space between the house and the trench so the ground is loped away from the house. You'll need to compact this soil so it doesn't settle with the next rain.
Thank you for this. it has been mentioned before. What do i do about the state of the walls after we have built the drain?
How do i repair them?
Once the source of the moisture is gone the walls should dry out on their own. Then you can scrape off the peeling paint and plaster, then re-paint and re-plaster
Will a general plumber be able to do this for me? can you recommend someone. I live in Centurion SA.
This is more a job for an excavating contractor even many landscapers would be able to handle this. I'm sorry I'm not allowed to make referrals.
Thanks for all your help. Much appreciated.
