Problem with drainage on new patio
Hi I've recently laid my first patio (3x2 slabs)but when it rains there is a pool of water in the centre of the patio,is there any way of fixing this with some sort of drain rather than lifting half the patio and relaying?
You can fill threw hold on slab or relay it

Without relaying the patio with the correct fall, you have limited options.
You could drill a hole through the patio and the sub-base and get a bar or something to make a deep hole to act as a soakaway, but how effective this will be depends on your soil, if it's heavy clay the hole will fill quickly.
Or you could get an angle grinder with a mortar rake disc and cut a slot along a joint line (assuming you have left a sufficent joint). If you create a drop in the line you cut, starting high in the middle to low at the edge, the water should drain off to the edge.

hi, would be best to lift and relay the patio with the right fall. if its just the flags in the middle you might be able to just lift and relay the middle ones use more sand and cement as required to bring the height up.
