Coping is required if an in-ground swimming pool is made of Steel. The coping conceals the exposed shell shoulder and raises the completed pool elevation to the level of the intended decking. Furthermore, it keeps water from getting under the pool, which is crucial. Coping, in addition to being a requirement, may provide a beautiful touch to the border of your pool or spa. Aside from being naturally gorgeous, coping can keep your pool or spa cool to the touch and safe for anyone entering and exiting the water.
