We are building a small bunkie (8' x 12') at our cottage and are debating the merits of sinking sono tubes as a foundation vs using gravel, patio slabs and concrete blocks. We are water access only so are looking at carrying all materials in by boat and have come to town to rent an auger to dig holes for the sono tubes but are now finding we need a HEAP of concrete to pour into 8" tubes. Any suggestions?
