I built a paver patio and used silica sand for in between the pavers. Its washing out...help.?

Question

The sand just washes out of the cracks when it rains or gets wet...silica sand was recommended by a lot of people. Does it normally wash out? Does that change over time? Other recommendations?

Answer 1

add more sand-its settling-plus at ends is it washing out like a stream-add something to stop it from washing out there-good luck

Answer 2

The best thing to do is wash/vaccuum it all out, then replace it with UniLock Polymeric Sand.   You sweep it into the seams, remove excess, moisten it, and it hardens in place.

You can make your own with sand and mortar, or a grout mixture, but they're too hard to remove from the blocks prior to wetting.
