Hi all,
Just laid some ACO channel and a short concrete path in a difficult spot behind my garage.
Because the concrete had "nowhere to go" I installed a 10mm foam expansion all the way around the edge. This isn't a massive area just 2.5m x 0.9m.
Anyway, about the foam expansion gap, will rainwater get in there and freeze, potentially giving the brick wall issues? Should I perhaps cover it with a pvc bead or maybe some sikaflex or similar?
By the way, there is DPC at the top of those bricks underneath the timber, but I also put a DPM under the concrete and up the back of the ACO/expansion 10mm foam to keep water away from the bricks. It has a fall to a drain.
Grateful for your advice
