Why the Underlay is Critical

The included geotextile underlay provides essential protection:

• ✓ Cushions against sharp stones that could puncture the liner
• ✓ Protects from root growth pushing up from below
• ✓ Prevents ground movement damage from soil settling
• ✓ Extends liner life by eliminating abrasion
• ✓ Makes installation easier by creating a smooth base

Without underlay, even the best liner can fail. We include it FREE because it's essential for long-term success.
