crumbling ledge over waterfall area
My landscape designer insisted that the ledge in my back yard which is now exposed, after blasting for construction of a new house, was the perfect spot for a waterfall. So, yesterday while his guys were washing the ledge w/a hose, a fairly large piece of ledge fell off. I'm worried about ice this winter getting into the crevices and expanding sending the rock falling when it thaws. Is there any product to squirt into the crevices, some kind of adhesive/mortar made for this purpose?
