What you need beneath the paving

Think about what you might need to run under your drive, paving or foot path. You might need to run electrical for out door lighting, gas for outdoor BBQ, water for an automated watering system. So think about running industrial strength tubing under your paving. If you don't, it's too late once the paving is done and trying to get the services under the paving will be a hell of a job and cost much, much more (Cath Proud).
