 Wall and Bracing System: PBPools Polymer Pool Walls and braces are molded to exacting specifications based on through research and engineering. Each of the straight length and radius panels have uniform rigidity, flatness and strength, derived from the strategic placement of ribs. These polymer panels are the most resistant to all types of underground deterioration. Polymer walls and braces cannot rust, erode, rot, crack, or splinter. In addition, they offer a higher strength-to-weight ratio than steel, and are surprisingly light weight for ease of installation. There is no stronger, more functional brace in the industry. Fastened at the five stud-and-socket locations, the brace features a wide rear stabilizing pad that uses backfill pressure to keep walls plumb and straight. A polymer stake provides added support in most conditions, but in very rocky soil, a heavy steel drive stake is available. The 5 inch wide by 28 inch top surface of the deck-support brace is designed at an angle to align with proper drainage slope of decks. 

Joining system: PBPools Polymer Pool Walls systems are engineered for long-term structural integrity over the lifetime of the pool.

Pool Base


 inground swimming poolThe purpose of the pool base is to provide a smooth surface for the pool liner. A smooth surface is less abrasive on the liner and makes it easier to keep the pool clean. There are four choices to use for the pool base. 1) Sand, 2) Sand and portland cement, 3) Sand, portland cement and vermiculite or 4) vermiculite and portland cement.Inground swimming pool install









1 Sand is the most economical and works well in play pools that do not have a steep slope. The amount needed will vary by pool size. The sand should be mason's quality and spread about 1"- 2" thick.
2 The most common used pool base throughout the years has been a mixture of sand and portland cement. Portland cement is available from your local hardware store.
3 The best pool base for most homeowners is the sand, portland and Vermiculite mixture. It is economical and provides a smooth soft surface. This is also a way for pools in high water table and hard freeze areas to minimize the amount of sand used in the base.
4 The vermiculite and portland cement mixture can be purchased in two forms. The pre-mix also known as pool-crete is mixed with water. The pre-mix can be difficult to work with and more prone to problems than the more economical to ship, Vermiculite that is mixed with portland cement and water.


Additional mixing and application information is provided in the Inground Swimming Pool Installation Manual.


The actual amount of material needed will vary depending on the dig and thickness of the base used. This table can be used as a guide. It is based on a 2" thick pool base. The sand/portland mix or the sand/portland/vermiculite mix is generally the best choice for most homeowners. The Portland/vermiculite mix should be used for high water table areas and hard freeze areas.
