I need some advice from you - The Experts. Please HELP!!! Thank you.
My house is finishing soon and will have PCI in a week time. Me and my wife is very exciting with our new home.
When I visit the site on the weekend, I find few issues with the house and one of them is with the gutter drain pipe at the back of the house. Photo below.
All the other gutter drain pipes went straight into the ground. However, this one at the back go horizontal along the wall for 40cm then bend around the wall corner and go down in to the ground. The issue with that is I am planning to pave a footpath alone the wall and this pipe is so close to the ground so I cannot go above or under it.
Here is another photos I took earlier to show why it have to bend around. The extra concrete piece left from the slab is blocking the pathway. Photo below.
The concrete piece is left there since the slab is done and it is cause by the bad form work from the slab. I thought the builder is going to cut the extra piece out before laying the pipe.
My questions are
1, Is the current pipe work build according to the building standard, is there any regulation regarding the depth of the drain pipe need to bury underground, it is just 1 brick height under ground level now?
2, Can I demand the builder to cut the extra concrete off as it is from bad slab work, even it is buried underground and cannot be seen. I will have to paid to remove it in the future when I try to pave that area as the ground may sink differently.
As I know nothing about building myself. It is hard for me to judge the finished work. Is the builder doing the best he can for the problem or it is just some lazy builder who try to hide the wrong doing? I need advice from some experience builder in this forum, will you do as what his builder did or what you will do to fix the issue? How much it will cost me to fix that in the future.
Thank you for reading and really appropriate anyone can give me some advice.
Have a nice day ^_^
