covered by coping, which hides the liner.
Pool liners do have limitations. In particular, drains
cannot be installed at the bottom of the pool. Difficulties
To install a lined pool follow these instructions:
Mark the pool basin location (Figure 38–1A).
Excavate the pool basin to proper depth. Designs
Verify that the ledge is level along the entire
perimeter. Use a 2 × 4 with a level resting on
top to verify level across the pool. Adjust grade if
necessary (Figure 38–1C).
Irregularities in the bottom or sides of basin walls
can be corrected by filling holes with sand.
Install a spunbond geotextile protective barrier
(liner pad) over the entire basin, including the
sides and coping ledge. Trim the barrier at the
back of the coping ledge.
Lay out liner and trim to rough dimensions
length at the rim and D equals pool depth
Liner width in feet = W + 2D + 3, where W equals pool
width at the rim and D equals pool depth
