How to fix drainage issues on pavement around house

bnw · Nov 28, 2018 4:10 pm

I recently installed a pavement/apron around the house. I noticed there are two large water puddles after a rain. I talked with the concreter and he agreed to fix them, but did not specify how he would fix them.

What would be a proper long term solution for these issues? I would like to have some idea before I discuss with him.

The second problem is one of the water puddles is on the same level as weeping holes of my neighbour's wall. I'm pretty sure any excess water would leak into the neighbour's wall. The concreter has kept proper gap for weeping holes of my walls but not for neighbour's walls. The neighbour's weeping holes are lower level than mine. What is the right solution here?

Cut out concrete rectangle from downpipes to exposed aggregate concrete, extend drain to the middle of the area (low spot) and re concrete making sure it drains into outlet.

Thanks a lot for the advise.
I have another question, what is the solution for neighbors' weep holes being on the same level as my concrete (Their floor level is lower than my floor level). What is the proper way to handle such cases?
Thanks again.

This is one of the increasing number of issues that people are now facing with zero boundary lots and the answer to your question comes back to the natural ground levels and the surveyed boundary as to which builder has (possibly) been negligent in their responsibility. Which house was built first?

The concretor has not sloped the path to set it below your neighbour's weep holes or had suitable drainage installed. Do you know the path's slope (the fall in mm away from the slab over 1 metre)?

Regulations vary between the States but you have not posted what State you are in. Without knowing this or the path's slope, it is not possible to say whether your neighbour's weep holes would have remained at a compliant height had the path been sloped differently and suitable drainage installed but the concretor hasn't done anyone any favours from what I can see. You can't move weep holes.

The links below relate to one member's dramas with weep holes, drainage and ground levels (and some other issues) at hand over. You may have a better understanding of your own situation after having read through these threads.

A couple of new members who are concretors have been giving good advice on other threads and hopefully they will also see your thread but again, you need to state where you have built. To have the best chance of concretors seeing this thread, it should have been posted in the Paving and Concreting sub forum but you can ask Homeone to have it moved.
