Gunite Pools We Install
Rebar Cage Assembly
Steel handles the tension loads concrete simply cannot. Bars are bent to the excavated profile, tied on the grid the plan specifies, lapped correctly at every splice and lifted off the subgrade on chairs so concrete surrounds each bar completely.
Shell Shooting
Dry material and water meet at the nozzle and strike the steel at high velocity, compacting as they land. Working upward from the deep end, the crew builds thickness in passes and keeps consistency across floor, cove and vertical walls.
Steps and Benches
Entry steps, swim-outs, spa dams and sun benches get carved from the same monolithic placement as the shell around them. Forming these in place leaves no cold seams for water to find and no bolted-on structure to crack away later.
Plumbing Tie-Ins
Skimmer throats, returns, main drains, light niches and feature lines all pass through the structure. Each penetration is blocked out, sealed and fully encased as material goes on, with every line held under pressure so an accidental strike shows immediately.
Shaping and Screeding
Hand work decides the finished geometry once material is down. Crews cut, rod and float the surface to true the floor slope, sharpen the radius at the cove, level the bond beam and leave a profile ready for interior finish.
Curing and Cure Watering
Concrete gains strength through hydration rather than drying out. A watering schedule across the first week keeps the surface damp, holds shrinkage cracking down and lets the shell reach the strength the design assumes before any load is applied.

Structure First, Because Everything Else Sits On It
What is the difference between gunite and shotcrete?
Both are sprayed concrete, and the difference is where the water enters. Gunite arrives dry and gets hydrated at the nozzle, giving the operator control over the mix, while shotcrete comes wet-mixed from the truck and must be placed quickly.
How long does gunite need to cure before plaster?
Most builders wait 28 days for full design strength, although tile, coping and decking usually proceed after roughly a week. Interior finish applied too early tends to bond poorly and telegraph shrinkage cracking straight through the new surface.
Do I need to water a new gunite shell?
Yes, and it matters far more than most owners expect. KC Pool and Spa leaves a written watering schedule with every shell we shoot in Kansas City, MO, because hydration over that first week is what actually builds strength.
Are cracks in a gunite pool normal?
Hairline crazing in the plaster layer is common and almost always cosmetic. Structural cracks that leak, run through the shell itself or widen over time indicate soil movement or missing steel, and those need investigation rather than patching.
How thick is a gunite pool shell?
Walls and floor are typically shot 6 to 12 inches thick depending on depth, soil conditions and design loads, with the bond beam and deep end heaviest. Thickness gets verified during shooting rather than assumed once the crew leaves.
What goes on top of a gunite shell?
Gunite is structure, never the swimming surface itself. Plaster, quartz or pebble finish is applied over it, with waterline tile and coping around the perimeter, and that layer is what the water and swimmers actually make contact with.
Can an existing gunite pool be reshaped or made larger?
Reshaping is realistic, which is one genuine advantage of concrete. KC Pool and Spa cuts into existing shells across Kansas City, MO to add tanning ledges, extend depth or change an outline, tying fresh steel into the old structure first.
Is rebar really necessary in a gunite pool?
Absolutely, without exception. Concrete resists compression well and tension poorly, so a properly tied steel cage is what keeps a shell from cracking apart as the ground moves, and bar spacing and lap length matter as much as the presence of steel.
