Hi, i have a customer that wants a 10 x 10 ft. paver patio, with small retaining wall, probably about 20 linear ft. for wall. Approx. how much stone if digging the 7 or 8 inches down? and then how much sand? sorry for noob questions, but im just learning. Just wondering how you guys price a job like this. Also i do not have a Bobcat to dig out the area. Is there another tool besides shoveling to make job easier? Also as far as edging, i have previously used plastic edging for a sidewalk, which i think sucks., what do you guys use for edging, i mean what is best to use for edging so the perimeter pavers do not shift out. I have done a couple sidewalks , retaining walls, but this will be my first patio, so any suggestions i am open to.
