G235 Steel
The type of galvanized steel typically used for inground pool walls. G235 steel has a 14-gauge thickness (about 1.9mm) and coated with 2-3/4 ounces of zinc per square foot. The zinc acts as a rust inhibitor mainly for ground water that may get near your
inground pool.
Gasket
A gasket is a mechanical seal that fills the space between two objects, generally to prevent leakage between the two objects while under compression. Gaskets are commonly produced by cutting from sheet materials, such as gasket paper, rubber, silicone, metal, or a plastic polymer.
Gate Valve
The type of valve that spins "lefty-loosey; righty-tighty, like a hose spigot. Commonly found to be leaking air or water.
Grout
A construction material used to embed rebars in masonry walls, connect sections of pre-cast concrete, fill voids, and seal joints (like those between tiles). Grout is generally composed of a mixture of water, cement, sand and sometimes color tint which is applied as a thick liquid and hardens over time, much like mortar.
Gunite
Gunite is a brand-name of a concrete application process that pumps and sprays a concrete mixture through a hose and gun. Pressure sprayed Gunite is easy to use to create curves and special shapes, making it ideal for forming walls, steps and the floor of custom
inground pools, along with bridges, dams, canals, locks, tunnels and pipelines. Gunite is pumped wet through the hose, while an alternative option ‘Shotcrete’, is mixed with water at the gun nozzle.
