G'day forumisers Got a little problem, well not mine but I have to hear about it so its more of a PITA! The neighbours next door each time I see them always ask me if im using the sprinkler or got a tap running as they have a water running down the retaining wall and a channel they have dug (ill get a photo soon) Basically, im renting a new place, the owner built a retaining wall for the new houses - 2 on a battleaxe block. The below neighbours, also battleaxe block have concerns about the water coming through wall on occasions plus have dug a channel to divert the water to a storm water pipe at the front. Without the channel both driveways goes to sh!te as its just dirt. first question, do WA commonly use ag drains in retaing walls? 1.2m to 1.8m approx wall height. I told the dude to call the shire blah blah blah. they have and gotten no where repeatedly. It look like the new house hasnt put in any drainage, but no one has confirmed so we can assume they havent. The owner did the earthworks themselves apparently Other thing that the neightbours like telling is there was an old well on the property. They think that has to do with it, I tried to explain the "water table" to them and Old Timmys Well isnt really causing the problem, but the ground water. any well experts here?
