Why do pools crack?
The most common cause of pool cracks is ground movement. Certain construction issues and freezing conditions, while not common, can also cause pools to crack.
Soil shifting, flooding, and freezing temperatures are all conditions that negatively affect the structural integrity of your pool. Is your pool leaking water? Let us help you determine when leaks are serious enough to require repair. Superior Pool Service will consult with you on how to determine exactly where and how severe your leak is. Once this area is located, our Service Personnel will take the appropriate actions to fix the problem. One phone call is all it takes to get your pool back in proper working order. Our goal is to help you enjoy your pool without distraction.
Cracks in your pool surface are concerning but common. The most common cause of pool cracking is ground movement. Not all cracks need to be addressed as emergencies however, so let Superior Pool Service perform a dye test to see if they are indeed cause for immediate concern. We will pinpoint and repair leaking cracks before they become unmanageable.
Severe cracking can be the source of water loss in your pool. If your pool is leaking water, an epoxy injection followed by a topcoat of a flexible waterproof membrane and a plaster patch sealant is Superior Pool Service's typical protocol. In extreme circumstances, the structural integrity of your pool may be compromised and therefore also deserves immediate attention. Superior Pool Service is qualified to address these issues as well.
Will the fix be permanent?
Since all crack situations are different, there is no guarantee that the fix will be permanent. Unless the cause of the crack is identified and addressed, the pool may continue to crack.
What is done?
The first step is to sawcut any cracks and chip out the plaster to expose the gunite. At this point the crack is evaluated for repair. Any cracks smaller than 20 mil will not accept injection of epoxy and will be topcoated only. The topcoat provides a flexible waterproof membrane to prevent water leakage through the crack.
In cases where the pool has cracked in excess of 20 mils but not greater than ¼", the crack will be pressure injected with epoxy, or in essence "glued" back together. The epoxy will be allowed to set for several days, and then the epoxied crack will also be topcoated with a flexible waterproof membrane. In each case, after the topcoat is complete the materials will be allowed to cure, at which point a plaster patch can be applied.
In severe cases where there is damage to the gunite or to the rebar in the gunite, areas may need to be jackhammered out and rebar replaced/added to solve the problem. In cases where this work is required, additional charges will apply.
