Water collecting on the top of my artificial grass

The key to effective drainage lies in the surface the artificial grass is laid on. After all if there is nowhere for the water to go to it will just sit ontop of the artificial lawn.
If the surface that the grass is laid on is not adequately prepared with a suitable substrate that wil allow drainage (such as a compacted 15mm sand base) or is laid on a smooth hard surface such as concrete slabs or timber decking it is probable that excess water will stand on the surface of the grass. So there needs to be a small slope on the area the grass is to be laid on or the base needs to be well drained. Artificial grass will not make water disappear by itself!
Most grass ranges have drainage holes incorporated in the backing at time of manufacturer however it may be found they are not in the best places or become blocked. This issue is alleviated by putting a small slit in the backing of the product in the appropriate place, care must be taken to cut the backing and not the pile and ideally can be done from the back of the product.
If the drainage is poor excess water can easily be swept away but the key to successful drainage is always a good base!
