My back yard is concrete slab. when it rains shallow pools of water are left behind. i've noticed in town both concrete slabs and large areas of paving often have a groove or grooves(approx 7mm)cut in them. Is this something to overcome the pooling?

Any sugestions as to what the grooves are for and how can I stop the pooling

thanks
