How to improve drainage (simply)

Hi all, got a 1970s house in Western Australia. When it rains, water pools on bits of my concrete paths and car port (see pictures) There’s an exterior drain that water from sink flows out into - but there’s a deliberate “lip” around it to prevent storm water flowing into it. If this lip weren’t there that would solve my water pooling issues. I think the pooling is exacerbated because the concrete slabs outside have shifted over 5 decade (clay) and there’s a bit of heave - but I’m hoping this will stop or slow the heave. Any tips or advice on how to fix this myself (without paying thousands for a new outdoor drain) Secondly (the last photo) I have a storm water pipe from gutters that currently flows ONTO a concrete path - next to where two outdoor concrete path/slabs meet, and I think the moisture has caused them to shift slightly. What would be the best way to prevent this? Just an ugly elbow to flow the water into the astro turf next to it? submitted by /u/Seedy_Melon [link] [comments]
