Solid floors are a lot more substantial and require the ground to be made up in layers of ground sub base, sand, compacted hard core, damp proof membrane, insulation and concrete. Gunite is superior to alternative pool construction techniques such as vinyl liner or fiberglass pools in terms of structural strength and design options. The advantage of a solid ground floor is the elimination of dry rot and other problems normally associated with hollow joisted floors. This process is being used in retail stores, large box stores, warehouses, industrial manufacturing, healthcare facilities, restaurants, and commercial garages.
