Hi all, long time lurker and previously active long long long ago during my first go around with putting in a pool. We relocated from Massachusetts to North Carolina a couple years back, and first priority was finding a pool builder and transforming our swampy backyard into our area of respite- similar to our previous pool and home in MA.

Back in 2008-ish, we went through this process in the Boston suburbs. The build was long and painful. I learned a lot from the experience but in the end the result was spectacular. For anyone interested, our build was documented in the old Garden Web site...a fragment of it still exists on that site: https://www.houzz.com/discussions/2546615/david-pool-build-almost-done-used-to-be-our-pool-build

Fast Forward to 2023 and our move to North Carolina. We found a beautiful home, nestled in a very wooded neighborhood with large lots. Privacy and space! :) We are on a 4 acre lot but much of it is wooded and the trees are protected. The previous owner had designed the backyard poorly. Drainage and standing water were a big problem, and to add insult, he erected a strange rock wall (more concrete than rock) that enclosed a moss covered dirty stone patio. I was seriously concerned a pool might not be possible, but we found an excellent full service builder that assure us, the problems were not insurmountable. We signed up in October of 2023 and waited a few months for the design presentation. We were absolutely stunned with the beautiful transformation plan....$$$$!! Slight budgetary modifications were made and we embarked (we were familiar with their work given my work colleague had completed a massive project with them...truly outstanding workmanship, communication, and goal to make it perfect).

We went with a free form pool, spillover spa, rock water feature, paver patio, and a fire pit. This is stage I, later we will do plantings and landscaping per their original plan which encompasses both front and backyard. We chose a roman travertine coping, Eva techno Blok pavers, and a stone fascia for the spa and fire pit that matches our home's chimneys.

The hole was dug in mid September but significant rains delayed progress until late October when the shell was shot. While it cured, the demolition of the old patio and wall proceeded. November and December saw rapid progress with drainage, grading and the patio. The January brought things to a grinding halt due to the rare severe cold and snow. Things picked up again in February and we are about done. We added a dry creek along the back of our cleared property to divert water away from the pool area and dry up the surroundings. It turned out quite nice to our eyes.

Our equipment and electrical were done this past week and now the rains have come back. The remaining things to complete are the fence and plaster.....AND YES we are struggling with the final choice of YOU guessed it.....Blue Granite, Blue Surf, Prism Blue pebble sheen lol!

The one thing we were always disappointed with in our previous build, was the water color. We had hoped for a rich darker blue. Our builder in Massachusetts used RiverRok and he recommended using a mixture of two blues. It turned out very green..yuk! It wasn't a pretty teal green but rather a darker green with blue hints. The photos in the previous build thread do not truly capture the green. It looks lighter and blue-er than it appeared in person. So obviously we are struggling with this choice and hope to avoid the same result.

Here are some pictures of the original plans, choices, and build to date. We have tentatively decided on Blue Granite and keeping our fingers crossed. Comments and suggestions welcomed!
Cheers

PS Ignore the telescope in the picture....only one I had of the previous patio area. More to come....

Here is our thread to help pick out plaster colors:

Showing this will also say you cannot go wrong with Blue smurf surf LOL It as blue as blue can be! The plaster part really does look like Smurf!

The blue Smurf is really nice but after seeing it in person and given our wooded setting we decided that something more subdued would be better. We are going with Blue Granite.

They came out today and cleaned out the shell. Lots of scraping dropped mortar from the stone and tile application, powerwash and vacuum, followed by an acid wash. They also trimmed the return outlets and light locations then filled in and smoothed those spots. All looks good and ready for the pebble. Unfortunately, temps will be below freezing for large parts of next week so they are holding off on the pebble for another week or so. Slowly getting there....

Thanks again.

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- IMG_6808.jpegIMG_6793.jpegIMG_6794.jpeg
 
Well I guess this forum is not very active or my questions weren’t seen.

Today they came and chipped out some weep spots. Then they applied a base layer followed by the membrane-c.

Interesting look to this stuff. Went on blue then turns dark gray.

Next week they plan on applying an adhesion layer then finally pebble.

Sorry you fell through the cracks last week and went unanswered. :confused:

For the iron, if the 0.1 is true, it would never reach staining level IMO. You get about 4 ft of rain per year, and will rarely have to fill. Dry spells do happen, so you will fill at times, but not 1 to 2 pool volumes a year like the hot climates.

But you'll consistantly drain more than you fill so theoretically the pool won't ever be 0.1 for long.

Plenty of things could change with the fill source, or the home plumbing, but for now I wouldn't be concerned at all.

Thanks for the reply! Appreciate your thoughts.
I was able to test with my Hanna hand held spect …so the iron level is at about 0.53 ppm so it still not likely to be an issue for quite some time. I’m going to add a Culater filter to the spigot for the auto topoff just to deal with that small amount of iron.

Contractor came out to see the final membrane - c. Plan is to apply bondcoat on Monday or Tuesday and if weather holds pebble on Thursday followed by acid wash and fill on Friday. Finally the home stretch.

Here’s how the membrane-c looks-

Some may have seen my build thread. We are at the final stages awaiting pebblesheen and after some pretty heavy rains there was weeping and concern due to our high water table. Our builder decided to apply a waterproofing layer to the entire pool called Membrane-C. Yesterday they came to apply the Bond Kote layer prior to plaster later this week. It was raining during the morning and they waited for it to pass. They thoroughly dried the shell and used some propane flame guns to warm the shell I believe. They applied three coats of the Bond Kote, waiting for a while and drying it with the heat guns after each coat.
About 2 hours after they finished and left we had rain come through. Later at night more rain.

Today most of the rain has dried but there appears to be areas of white residue where things are still a little wet. Does anyone know if this is a concern?
Thanks!

Thanks, Turns out it was just efflorescence. At first it looked like it had washed off the bond cote and exposed the underlying membrane-c but it turns out all was already set. They applied 3 coats and waited in between each coat so we are good. They are going to gently acid wash the efflorescence before doing the pebble which is scheduled for tomorrow.
 
Well we are done! Pebble applied on Thursday after a light power wash of the Efflorescence. Interesting change in my previous application. After applying and smoothing, they sprayed with with this pinkish red stuff, then kept working it and washed it off. Looked really good when they were done.

The next morning, they did the acid wash, neutralized, and rinsed. Then followed it up with a power wash of the entire application. That really got the pebble well exposed. After the fill, we added basic chemicals and fired it up. Very little dust, that power wash was very helpful. Water had a teal green at first as expected, by the next morning, gorgeous blue. We are very happy. Here's some photos of the last stage.
