Had a search on the forum but couldn't find the answer to this.
We're about to lay a gravelled area along the edge of the house, where I know there are quite a few buried PVC pipes (both for foul water and rainwater). I'm pretty sure the pipes are not buried hugely deeply and are not encased in concrete. Besides being a bit worried that they are not protected enough from heavy loads on the surface, I also don't want to squash the pipes when I compact the sub-base. Am I worrying too much, or should I be trying to put a concrete layer around them? If so, what's the best order to tackle things? Dig out the whole sub-base first, or try to find and just dig around all the pipes first so that I've got trenches to pour concrete into.
