I had my gunite swimming pool remodeled within the last week - expansion joint was added, all new coping, all new tiles. Work was finished two days ago and I've noticed that there are hairline cracks in the grout below the tiles in a section of the pool - about 1/5 of the pool area. Is this a concern?
Hairline Cracks in Grout Below Pool Tiles - Newly Renovated

Very common when two different cement products meet. Keep an eye out for the size and any movement as in grout missing, that would be an area of concern.
Thank you! Pool company returned and owner told me the same thing and added that the hairline cracks were superficial. He used a special grit and buffed the surface where the hairline cracks were present and they disappeared.
