OK, this is my first post and I really need some help/advice. After several months of planning, picking the pool builder, etc., we finally started our pool build this week. The hole was dug earlier in the week and gunite was scheduled for today.

Unfortunately the gunite crew didn't start until 3:00 or so and it got dark before they finished. As such they are now scheduled to come back tomorrow to finish the pool.

Is this going to be a problem for me? I always thought you should pour concrete in one application and while I realize there is a difference between gunite and concrete, I would think the same rule would apply.

Am I worrying needlessly or is this an issue?

Thanks in advance

concrete/gunnite all the same animal.Diff is in size of aggregate. cement content, admixtures and how it is applied.Starting and stopping application will result in a cold joint, which may or may not be a problem depending on where it is. It is very difficult to beleive gunnite contractor isnt aware of this.
Good Luck-Joe

It is best if the concrete is done in one monolithic application.

The cold joint is at risk for cracking. You should thoroughly document this, including pictures and measurements.

You should ask the contractor to give you a written guarantee that specifically covers any adverse effects of the cold joint.

What is the diameter and spacing of the rebar?
What is the thickness of the concrete?
What is the rated strength of the concrete?

A pool can be done in multiple applications. However, there should be extra precautions taken by a contractor if they plan to shoot the concrete in more than one application.

The rebar diameter should be upgraded.
The rebar spacing should be reduced.
The soil should be tested and certified for stability.
Additional support should be engineered into the design, which can include things like piers or piles to give additional support.
The rated strength of the concrete should be upgraded.
The thickness of the concrete should be upgraded.

make sure that the rebar is clean and all rebound is removed. if they stopped on a wall it should be at a 45 degree angle. use a bonding agent to wet the area before re-shooting. good idea taking pics and putting something in writing.
