TL;DR
Pool coping is the cap of natural stone, precast concrete, brick, or paver units that finishes the top of a pool's wall, bridging the shell and the surrounding deck while shedding splash water away from the structure. Profiles include bullnose, square-cut, and rolled edges, and the joint behind it doubles as the expansion joint that isolates deck movement from the shell.
