i'm thinking of having my 20 x 40 sand school topped up with some rubber. its been down 4 years now, with padstow sea sand. anyone in the south west will know its a good type of sand! it drains amazingly but just think it needs a bit of rubber to stop it freezing in the winter and making it less deep in the summer. any ideas about how much i need to put on???
