Just spent a very entertaining 1/2 hour on the prom at Rhos, below the Caley prom. As we returned to the car after walking the dog, we noticed a white van parked between us and the railings bordering the sea. Two men, sitting inside it...one napping and the other doing something with a mobile phone. They eventually got out, got various tools from the back and began mixing cement in a bucket. One chipped a small piece of concrete from the edge of the sea wall thus creating a hollow about 6" across. It then took the two of them 1/2 an hour to pour, level and pat down the resulting mess, much of which ran down towards the beach. The tools and bucket were then loaded back into the van which moved about 20 yards and the whole process began again. Not the council by the way, but a drilling firm.
If I hadn't seen it, I wouldn't have believed it !
