1. 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.

From the inside of the flexible Figure 2 Rubber Gasket basin, insert the threaded end of Friction Bulkhead the bulkhead into the pre-punched Washer hole in the flexible basin. This will sandwich the rubber gasket between the flange of the bulkhead and the inside wall of the flexible basin (Figure 2).

As you are filling the basin with water, continue smoothing out the wrinkles from basin as you go, making sure to tuck the basin corners tightly into place. During this process, the basin can be filled to the bottom of the bulkhead opening.

To secure the basin, place a solid bead of masonry adhesive along the top course of the basin surround, with a generous dab also placed in the pre-punched glue points in the basin flaps (Figure 5). Then carefully place the next course of stone, ensuring that the flaps are pulled tight and there is no slack in the basin.

Flexible basins can be plumbed using submersible or external pumps. The number of pumps, their size and their location will be dictated by the water features being installed. See Figure 7 below for a typical submersible pump installation using an Atlantic TidalWave pump. Figure 7 1½” Street 1½”...

When plumbing multiple fixtures, run a main feed line along the back of the wall, teeing up to the individual fixtures (Figure 8). If plumbing multiple fixtures, it is best to install a ball valve in each line feeding the fixtures to provide more control over water flow.
