Footprints on bottom of inground pool liner?

I had an inground pool installed. We just turned on the lights at night and noticed footprints on the bottom. Can this be fixed? Call the pool company back. The bottom is normally sand mixed with cement. The liner will probably have to be removed and bottom smoothed. They should have checked that before installing the liner. Those printswi catch sediment and debris for the life of the liner.

What is under the vinyl liner of an inground swimming pool?

There are two parts to a vinyl liner pool: the bottom and the walls. The walls are the first 3 1/2' down from the top, all the way around the pool. There are many different types of walls including galvanized steel, aluminum, fiberglass, polymer and concrete. The bottom, everything below the first 3 1/2' down, can be made from cement, a cement/vermiculite mix, a sand/vermiculite mix, a cement/sand/vermiculite mix, or just plain sand. What is used under the pool liner depends upon the preference of the pool builder and the specifications of the homeowner or contractor.

Where can you purchase vermiculite to repair your pool and how is it applied?

Vermiculite is available at Garden Centers. They use it in for plants and trees. Also, Home Depot and Lowes. Vinyl liner pools are built on the cheap. Rather than pour an 8" concrete bottom, or even shoot on gunite, by first building a cage of wire and Rebar, they mix cement with vermiculite and trowel on a 4" bottom. Without the vermiculite, the bottom couldn't withstand the hydrostatic pressure underground, and would lift up like a volcanic eruption. The vermiculite permits water to come up thru the bottom because the cement is now porous. Installation is accomplished by mixing the vermiculite into the cement prior to troweling it onto the entire bottom, which includes the vertical surface up to the bottom of the 3 1/2' wall (steel, fiberglass, wood, or whatever). Experience mixing and troweling cement is advised. Good luck

How do you drain inground pool without causing damage to it?

It depends on if you mean damage to the liner, the bottom or the walls. The liners go bad and shrink if not kept wet and evidentally this can happen very quickly. The walls should be held in place with braces and a concrete footer if it was installed properly and the weight of the concrete apron (sidewalk around pool should keep walls in place so these should normally be safe. The pool bottom if it is not too old is probably a mix of vermiculite adn cement from 2-4inches thick and this can be damaged if your water table is high in your area. If this is true them hopefully who ever installed pool should have put in a sump or french drains help keep water from coming up under pool and pushing the bottom up. You have to remember that at some point your pool didnt have water in it. ie during construction.

How do you remove excess rain water in inground pool?

To remove excess rain water in an inground pool, you likely want to get a filter. You can also install a drain at the very bottom of the pool, but this will need to be closed if there were water in the pool for swimming.
