"Overall I am happy with the Paving except for one very important detail: Six of the slabs have depressions in the middle of the slab, i.e. when it rains water collects in the centre and cannot drain away. As recommended I have laid the slabs on a slight slope but it would need much much more than a slight slope to overcome the puddling problem. I really cannot understand why any slab should be produced with this major defect."
