Can you use masonry sand under your above ground pool liner?
yes just remember the softer the better on the liner and on your feet
What type of heat transfer does adding insulation slow down?
Generally speaking, insulation slows the movement of thermal energy by convection. The dead air spaces in fiberglass insulation make it a good bet to put in walls and under roof spaces. Styrofoam coolers work because the many, many tiny air spaces in the styrofoam are places where air is trapped, and those are dead air spaces.
Do you have to put sand under a pool?
Yes by putting an even layer of sand down you will protect the liner from the irregularity's in the ground and absorb impact from above.
Is there a special sand for under liner for above ground pools?
That is most commonly referred to as " washed sand " also float sand , or mortar sand ,it has no stone or stone chips that will damage or stain the liner.
How long does it take styrofoam to digest?
Styrofoam is not digestible. The body will eliminate it before it would be digestible. Styrofoam should not be consumed under any circumstances.
Why do underground water remain warmer in winter morning?
I think it is because of the good insulation of earth surface to the under ground water
How do you know if ground water is coming in under pool liner?
One way would be to install drain tile in the yard around the pool deck to carry excess ground water away from the pool.
What causes wrinkles in a pool liner?
I'm assuming that you have an inground vinyl lined pool. This is a chronic problem with inground vinyl lined pools, and is due to ground water being higher than the level of the water in your pool. The pressure of the ground water is greater than the pressure exerted by your pool water, and the liner floats. A half baked solution, is to wait until the ground is no longer saturated before removing water. The real solution is to provide a way for the ground water underneath your liner to be removed. This can be a passive system with a small pipe going under your liner and allowing the ground water to drain off (but this only works if you can keep all parts of that pipe below the level of the water in the pool-which depends completely on the pitch of the ground in your yard), or an active pumping system which pumps the ground water out to a drain.
Do you need anything under the pool liner?
Sand is normally put under the pool liner to create a smoother surface.
When using Styrofoam board insulation inside the house is there a fire safety concern?
Yes. Many of the foam insulations (including expanded polystyrene) are highly combustible, and may not be used except when installed under a fire resistive covering, such as drywall.
What is burial wire?
It is a wire with special insulation that protects it under ground. On the wire there will be a stamp "UF" or underground feeder. That means that it can be buried directly in the earth.
Is there a way to replace the sand that has been washed out from under my above ground pool after repairing the leak which caused the problem I'd rather not drain it and remove liner to fix it.?
No the amount of weight exerted on the liner of even a litle water makes this imposible to do.
