The slab under our house is evidently not level or even (as I thought it would have) away from the centre of the slab to allow water to run off.
Nope our Alfresco area slopes towards the centre of the house, thus meaning when it rains any water that comes in and lands on the concrete flows towards the external walls of our house, pooling in the corner of our alfresco.
Is there anything we can do to turn this slope inwards into a slope outwards?
