The pool needs a stable, correctly prepared support system that matches the actual site and final installation level. Foundation design is a local project responsibility and should be based on the final project configuration, not a generic web rule.

Record soil and ground conditions, slope, fill, retaining, groundwater, existing slabs and nearby structures before local foundation design begins.
Pool size, installation level, equipment arrangement, surrounding deck and local loads all affect the site solution. Transport weight should not be treated as the foundation design load.
Surface water, groundwater, deck drainage and equipment discharge need routes that do not undermine the support system or trap water around the pool structure.
ORDRAN is supply-only. Foundation design, soil assessment, retaining and local structural verification remain with the purchaser's local project team unless expressly included elsewhere in writing.
