Can anyone recommend some decent companies to put in an arena for us? Planning permission is in place. We are looking for quotes for either someone doing the whole job, or quotes for someone to do the groundworks supplying stone/drainage/membrane, quotes without supplying the stone/drainage/membrane and we'll source those ourselves. Quotes for surfaces also required for silica sand and fibre mix. The surface must be good as one of my horses has a previous tendon issue and we need a surface that won't ride too deep. Once we have quotes we can decide on the best way forward. The arena will be 20 x 40m.
