With asphalt paving around excavated hole, the crew used a pallet jack for transport of materials from storage to the excavator. First a layer of filter fabric was laid down, then the pre-made waterproof liner by Webtech.

Be very careful to avoid puncturing the waterproof liner. The roll was lifted with straps secured to a pole that ran through the center. First day they placed about 23 cells along with the upper fabric layer on the floor.

Sand bags placed at the top perimeter keep the liner in place. A plywood sheet provides a staging area for stacks.

Contractor designed a lifting jig with straps suspended from an excavator. Ask for a drawing to build one for your project. This technique will prevent tall stacks from tipping when lowered into the hole, and also protects the top cells from getting broken.

This hand cart is a little too small. Use one with high support bars and handles for better bracing when tilted.
