Pool Construction Terms
If you have never owned a swimming pool; builders may speak a language that you do not understand yet! Many of our clients are brand new pool owners and mention that they do not know all all of the terminology that pool contractors use to describe and calculate the swimming pool design. This article will help you learn exactly what we mean when referring to the technical specs.
The swimming pool “beam” is an important part of the structure. This part of the pool is located at the top and traces the perimeter shape and will help identify the perimeter measurement of the pool structure. Usually this is where the decorative stone edge is installed just above the tile inside the pool.
The material that sits on top of the pool “beam” and follows the shape above the waterline tiles is called “coping”. The edge of the pool before water starts. Concrete decking will butt up to the backside of this material with a “control joint”. You have your choice from brick, flagstone, or travertine included.
The measurement of the pool beam, as in tracing the shape of the pool. Also referred to as the “pool beam”. The image below is just a general guide to the terminology. The pool perimeter is especially important in free-form shape pools when calculating the interior surface area.
Specs for rebar are standard at 10″ “o/c” which stands for “on center” making a 10″ x 10″ square. We supersede this standard spec by using more steel at 8″ o/c. So, we install a tight rebar steel cage. The “boxed beam” supersedes standards by including 4 of the 5/8″ steel bars in a continuous loop inside the pool beam.
Is a form of concrete that can be “shot” through a high pressure hose, applied at a high velocity our gunite cures up to 4000psi over time after hardening. Gunite applicators MUST be certified to ensure our lifetime warranty. PSI refers to the curing strength of concrete, how much psi must be required before it cracks.
This term refers to the square footage of area of water only inside the pool. As a 2d top down representation this is the footprint of the pool which can be understood as the size of pool, or how much space in the yard the pool will take up.
The interior of a gunite pool must be sealed with a quality finish before it will hold any water or be visibly appealing. The pool interior, surface is a material that bonds to the gunite shell and keeps the pool water from leaking, but is also has a very nice appeal to the overall look and feel of the pool. There are all kinds of crazy additives and prices but we have you in 40% quartz blend, with optional blue flakes on a white base with a 7 yr warranty.
Pool decking can be done in many ways; concrete, textured concrete, pavers, wood/trex, or tile. The area surrounding the perimeter of the pool is considered decking which can be 4″ thick concrete, to include footing and piers as needed along the edges to keep from cracking or separation.
After all of the above mentioned Coping & Decking are installed and after some time the material known as “Mastic” will seal the pool perimeter control joint. An exposed flexible type sealant with a decorative finish will ensure that water from the pool or rain will not leak into the control joint gap.
This is where all of the pool plumbing pipes merge together varying between 9 – 14 total pipes. The main trench will go to the pool equipment and each pipe into it’s respective connection.
The filtration pump is the main pool (or spa) pump that pushes water through the system and pool equipment. For pool+spa combinations the equipment will be shared. We offer several solutions for the right pool filtration pump from single speed, 2-speed, and variable speed models. This is the pump that will come on each day and help keep the pool clear.
Your pool equipment devices must be controlled by some device capable of reoccurring timers/schedules/run-times. We have several solutions ranging from standard analog timers to full digital automation with WIFI capabilities. Each of our digital pool controllers include the ability to control devices, set schedules, control lighting, and some models come equipped with wireless remotes and other advanced features.
Our pools come complete with automatic poll cleaners. These are robotic type pressure-side cleaners that will catch leaves, dirt, pine needles/cones, gumballs and all the sorts of things that drop to the bottom of the pool. We install the Polaris 280/380 automatic pressure side pool cleaners into our pools. Better than any AquaBot or Dolphin brand cleaners period!
Filtration is one of the key components to having a crystal clear pool. Our cartridge filters can catch debris so small in the pool water that you cannot see with your eyes! On a pool+spa combination the filter is shared between the pool and spa depending on what mode it is in. Our pools are filtered with Hayward Swim Clear cartridge with 4 elements that should only require cleaning about every 6 months.
The means in which you will keep the pool water sanitary. Chlorine fights against bacteria in the pool water. We offer several options for keeping your pool sanitary and safe; Chlorine Tablets, Salt Chlorine Generators, UV & o3 chlorine generators to suite your preference. Some options like chlorine tablets might be irritating to some swimmers, so you know we will have the right chlorine solution for your pool.
