Anyone have any verb ages in their contract about polysand? Here is what I use on my hardscaping contracts to cover polysand: A 1-year warranty against defects in materials and workmanship on any Polymeric sand work is included. The contractor will remediate the issue, replace or repair damaged items, or provide a similar replacement, to the satisfaction of both parties at no cost to the homeowner during the 1 year period. The period of 1 years will start upon the day of completion. Major natural events and acts of God will not be covered. Weeds, sand loss due to insects, and improper drainage of pavement will not be covered.
