Q-Set™ 250-750 is a hydrophobic two-part polyurethane Composite Backfill that expands to fill the peripheral void between a post and the hole. It forms a low-density, high-strength composite that can structurally support the post and maintain its upright positioning. It expands immediately after mixing and reaches 50% of full strength in approximately 3 minutes and is fully cured in approximately 2 hours.
Q-Set™ 250-750 significantly reduces labor requirements as no additional backfilling is required. Note: Q-Set™ 250-750 users must conduct their own testing to determine the support time required in their application conditions.
Q-Set™ 250-750 can be used to install new posts or provide a new solid foundation to straighten and stabilize a pole.
