Introduction
Thank you for purchasing the Atlantic Flexible Hardscape Basin. Before using this basin
please take a moment to review this manual. Flexible Hardscape Basins create a
wrinkle-free, easily plumbed reservoir for use with engineered stone basins.
Installation
Preparing the Surround
Begin by constructing the garden wall surround for the basin as per manufacturer
instructions. Atlantic's flexible basins are designed to work with 12" x 8" x 4" wall stones,
minimizing the amount of cuts needed. However, they can be used with any variety
of stone.
The opening should be 24" deep (from front to back) and 15 ¾" – 16" tall. The width will vary
depending on the size of the basin (48", 72", or 96"). The center of the bulkhead outlet will
be 10" high and 9" in from the side of the basin (Figure 1). Ensure that a space is left in the
wall for bulkhead installation. The hole should be 4" – 6" wide, depending on how you set
the bulkhead. Backing plates are provided to bridge gap(s) in the stone around the
plumbing, providing structural support to the basin.
When preparing the base under the basin, the ground must be compacted and level. Sand
or limestone screenings can be added to raise or level the base. Ensure that there are no
sharp objects that could puncture the basin.
Underlayment fabric can be installed below the basin for added protection.

Installing the Bulkhead
The Flexible Basin is equipped with one or two 1½" bulkhead fittings, depending on the
basin size. Install the bulkhead fitting(s) before setting the basin. Remove the retaining nut
and plastic friction washer, leaving the rubber gasket on the body of the bulkhead fitting(s).
The retaining nut has reverse threads. Turn clockwise to loosen.
