what sort of base should i build to stand a pool holding 2000 galloons? would a patio construction do?

Question

this is to put a summer childrens pool on - ist measures approx 12feet in diameter and is on a metal tubular frame and plastic pool

Answer 1

Some math:
Water = 8 lbs/gallon. 2,000 gallons = 16,000 lbs
Pool area: 12 x pi = 12 x 3.14 = 37.7 square feet

Weight of pool water per sq ft (not including children.)
16,000 lbs / 37.7 sq-ft = 424.4 PSI

You would need a massive (wood or steel) deck to support this load. I would not go that route.


A good solution, as mentioned previously, is solid dirt with a 2"-4" bed of compacted sand on top. Scrape the dirt to a level surface (or slight depression in center) - don't use loose dirt to fill low spots. Wet the dirt to aid compaction, then pour and level the sand. Mist it with water and then install the pool per instructions.

The side walls and supports will need attention to ensure a solid, level and accurate installation. Handle the vinyl liner carefully to avoid making any tears.

Answer 2

Whatever you put the pool on, if the soil/earth underneath is compacted and there are no voids either in the soil or under the patio material I can't see how much can shift. The weight will be spread over quite a large area evenly. Assuming the pool uses a liner I would just lay a couple of inches of soft sand on the leveled ground, underneath it.

Answer 3

2000 gallons (UK) is 9 tonnes.

Your patio would probably take it as the area of the base of the pool is quite large. it is also stationary. Vehicles would impart a higher spot loading, and they seem to park on patios with few ill effects.

I would fill the pool slowly tho!

Answer 4

Well, if you think a patio construction would hold 10 to 15 tons then go ahead. Don't underestimate how heavy that quantity of water will be!

Answer 5

Yeah, if it's a reasonably well built deck. you're looking at approximately 146 pounds per square foot
