Semi-inground swimming pools are sometimes called on-ground pools or deck pools. Smaller than inground pools, they're buried halfway underground and halfway exposed above ground, usually surrounded by decking. These types of pools appeal to those who like the lower cost of above-ground pools but prefer the aesthetics of inground pools.
Aluminum is the preferred material for these pools because of its resistance to rust or tarnishing. It also has an optimal strength-to-weight ratio, even during cold weather. Steel is sometimes used instead, but it only has half the strength of aluminum per weight. Thus, more steel is needed for construction of a semi-inground pool.
The prices of semi-inground pools increase with the size of the pool, but the cost of a small one runs $4,000 to 5,000 while a larger one can run to $14,000 or more. On top of that would be added the expense of decking, the cost of which depends on the material used in its construction.
Decking makes getting in and out of the pool easier and it makes the pool look better. Homeowners can surround semi-inground pools with concrete, wood, pavers (clay or brick material) or stone.
Semi-inground pools require less work and are easier to install than standard inground pools. They are adaptable to yards of any shape or size, because they can be built on flat land or even on the side of a hill.
