Gunite Question

[ashleilachelle]

This is my first time building a pool so I'm unfamiliar with gunite process. I don't know what it's suppose to look like within the first 24 hours, but this isn't what I envisioned so I thought I'd just get confirmation from all the veteran pool owners.

I live in Texas and it is like 100+ every day right now so I guess my concern would be that the parts of the surface dried/cured to fast and would cause issues/cracks later. I just need peace of mind.

Ash,

What are you seeing you don't like??

Gunite is just a base that they put the plaster. The plaster is what makes it smooth and water tight.

It looks pretty normal to me..

Thanks,

I guess I'm worried about the integrity of the gunite. I don't want it to crack later bc the surface level dried too fast. I live in Texas where the heat index yesterday was 115.

Looks normal to me. The holes in the bottom are important now as they prevent the ground water from pushing up on the gunite shell and popping it out of the ground. Right before they do the plaster they will fill these in and you will never remember they were there.

+1 on the recommendation to water your gunite several times a day to keep it wet and slow down the curing resulting in a stronger shell.

Setup a garden hoses with sprinklers to water the concrete. You don’t have to spend hours doing it. Just enough water to get the entire surface wet.

I’m watering my Gunite for my new pool shot Tuesday in Texas. 112 degrees. We started 10 hours after pouring.

A pool builder buddy helped me place soaker hoses around beam walls and there is a nice steady drip for 24hrs. I’m going to run it likely 10-14 days with this heat. It’s perfect how soaker hoses literally coat entire shell/walls.

If you look at ASA guidelines…they say 7 days of continuous water…not the talked about every few hours 3-5 times/day.

The data shows the concrete could end up 50% stronger with this slow cure method. The first few days are critical.

Can’t wait to finish.

I’m hoping you’d be willing to answer a couple of questions I have about gunite. I am having a swimming pool installed at my house in Florida. I was away when the gunite was shot a few weeks ago and didn’t know at the time that the gunite should be s

Gunite is the original tradename for what we now call dry-mix shotcrete. Shotcrete is a placement method for concrete, so recommendations for curing and protection follow general ACI guidelines for exposed concrete. ASA recommends a minimum of 7 days of continuous (not just a few times
