Gunite Swimming Pool Repair Products

When Gunite Pools Need Repairs:    

Gunite swimming pools are constructed by spraying a mixture of sand, water and cement onto a rebar frame. Since gunite is porous, a layer of pool plaster or other finish then has to be applied on top to act as a water barrier.

If pool plaster isn’t applied properly water can seep through, causing damage. And as gunite pools age, even properly applied plaster will require repairs to address issues such as hollowing, egg-shelling or delamination. Gunite pools can also develop major structural cracks, usually due to shifting ground or the freezing and thawing of water that has managed to permeate the gunite.

The type and extent of the damage — as well as the type of repair products chosen — will determine whether or not the pool has to be drained in order to make the repairs.


Questions to Ask:

  • How extensive are the cracks?
  • How much water loss is occurring?

AquaBond® makes a range of products ideal for professional gunite pool and pool plaster repairs. There are no steadfast rules about which one to choose, but you may find the following recommendations helpful:
