This customer’s decking felt more like a trampoline to walk on. Investigation proved that much of the supporting timber had rotted away, partly because a rainwater pipe was discharging under the decking. It all had to come out and new framing and decking laid including making sure that water could drain away from the space under the decking. The rainwater pipe was relocated and connected to a drain. Notice that there are two manhole covers that needed to remain accessible.
