Very small puncture holes

Is this something to be concerned about? :confused:


The floor under my liner is some type of coarse sand/cement mixture; my pool was installed last year. The other day while swimming with my goggles on I noticed that there are some high spots like tiny little pebbles under my liner only noticeable if you get up real close. However I have found two spots that appear to have a tiny, very small puncture holes in the deep end. I am not aware of losing any water, should I be concerned about this, or is this just a normal thing with liners?

Anyone?:confused:

If I had small puncture holes in my new liner after only a year that were obviously from improper surface preparation, I'd certainly be very concerned and would be talking to someone.
