Pool Renovation has Cracks in Gunite

[Walton80]

We are doing a renovation to our pool that was built in the 90’s that involves adding a spa, new beam, and a gunite step. We noticed that ground water is leaking into the pool through the new gunite in certain areas. The contractor says that this is not a problem and we should proceed to installing the PebbleTec.

I am concerned that the PebbleTec will not hold up correctly in those areas due to water coming in from the outside and I may have a problem after the contractor has been paid.

Any thoughts on my situation based on the posted pictures? Do I move forward with plaster or is this an issue that needs to be immediately addressed?

Welcome to TFP.

Cracks should be sealed with hydraulic cement.

I cannot assess the severity of the cracks based on the pictures and without knowing the rebar structure in the gunite. Do you have pictures of the rebar before gunite?

Plaster should not be done while water is weeping from the gunite. If you do there is a good chance it will stain the plaster. Plastering needs to wait until there is a dry spell and no water weeping from the gunite.

I would not plan to plaster in Northern NJ until June when things are drier and you have warmer air temperatures.
