I'm installing a new paver walkway, and I have questions about the edge restraint. I expect to use the plastic edge restraint that one nails with spikes.
So far, I have dug out the walkway, installed 4 inches of RCA (recycled concrete aggregate), and compacted the RCA. The finished walkway will be 46" wide, and the RCA is 58" to allow 6" on each side. I put landscape fabric under the RCA, with enough hanging out to continue around under the sod that will be on the outer 6" sections beyond the walkway. The walkway is a total of 503 square feet, i.e. over 100 feet long. It is curvey, with no straight sections.
Next I'm ready to buy and install the edge restraint. But I haven't found a product that I like!
I expected to be able to place the edge restraint directly on top of the RCA, nail it in place, then add 1" of bedding sand ONLY ON THE INSIDE, BETWEEN THE EDGE RESTRAINTS, then place the pavers on top. (Then compact and then add polymeric sand.) This arrangement appears here.
However, the edge restraints that I have found for sale are only 1.65 inches high. Now, with 1" of sand, this means that only 0.65 inches of the plastic will catch on the sides of the pavers. This doesn't seem sufficient to me.
Any ideas?
Thanks. Andy
