Well the weather just hasn't cooperated. Pebble was delayed each week first due to the very cold nights and then all the rain and storms. Then something came up... After some particularly heavy rains, we began noticing some weeping from the shell. A couple spots showed a little more than weeping. Our water table is high and there is a natural spring somewhere behind my property so this has raised concerns.
Frankly, the gunite/shotcrete shell was not the most aesthetically pleasing. There are some very rough spots where it seemed they forgot to trowel and there are lots of little surface holes and gaps. I know the roughness is better for the pebble to adhere but I was a little concerned from the get go. I was told they were using a hybrid version where the water is pumped in further back from the nozzle and gives a more wet version. My builder has come out a few times and agrees the shell has some imperfections. He brought out the owner of the gunite subcontractor and the pebble tech rep to look things over. Of course the owner of the gunite company said everything is fine, but our builder is not happy and has decided to have them apply Membrane C to the entire shell in addition to chipping out and injecting the weep areas as well as grind smooth some very rough spots. Plan is for that to happen next week barring any further weather delays. We are getting this big storm tomorrow but we should be in the clear by later Monday.
Has anyone had experience with the Membrane C? Curious other peoples thoughts on this.
Another separate issue- our well has a very high iron content. We have an iron remover and softener system for the whole house but I had my water treatment folks out here to make sure the spigot for the autofill was part of the post treated plumbing. It is luckily but the water still has 1ppm iron using a color change kit. (I used to do saltwater reef systems so I have a more accurate Hanna Checker but need to get some reagent to run the test). This water would only be used for the autofill (we are trucking in water for the initial fill), the question is how much Iron in the autofill water is too much? I know staining can start when the pool water reaches 0.3ppm, but I would expect it to be quite some time before the concentration reached that level simply using 1ppm top off water.
We checked the well's raw water while he was here.....yuk! pure orange. 10ppm iron! He thinks the liner of the well may be leaking or compromised....we are going to do a camera inspection of the well next week. Always something!!
Anyway, would appreciate if anyone can provide some opinions or thoughts on the above. Thanks!!
Here are some photos of the shell weeps-
