Happy 4th everyone!
It's been a long time since posting last, but we are finally started with the pool. Had some excavating work done to get things going. Have the area rough in and have my ring of crushed limestone in and packed one time. I have a questions for those that have used this method of constructing the base. Is the sand layer enough to guard the line from the stones around the outside? Should some type of liner shield between the crushed stone and sand? I have a lot of leveling to still to fine tune and set the patio stones, but any other suggestions based on the pictures would be great! Thanks a lot!
