I am installing a 26 foot Intex Ultra and have prepared the ground. 80 percent was level and I built up the rest of the 20 percent. I know I should dig down but the ground is hard and I am using hand tools so that is why I did that. I tamped the whole area using a vibratory compactor. I plan on using pavers under the legs where the ground was hard but I want to pour concrete footing for the area I built up. Has anyone tried this and does anyone think it would hold up. Thanks in advance.
