Swimming Pool Rebar Repair:
Rebar Bleeds / Rebar Stains

A rebar stain in a swimming pool or spa is a serious issue.
Rusting rebar will continue to corrode within the pool structure until all corrosion is removed. Although the bleed through stain may be small in size, the corrosion beneath the plaster (in the gunite) is always larger in scale (see photos for examples).
Left untreated, rusted rebar will eventually rust the entire pool.

We have two methods to repair rebar stains:
1- Underwater (without draining the pool, using scuba gear and special tools), or
2- Dry (we drain the pool and expose the rust with chipping hammers)

 

 

 

 

 

 

 

 

 

 

 

 

 


Rebar stains occur in swimming pools and spas when the rebar is not properly encapsulated with Gunite (or Shotcrete). Lack of gunite coverage over rebar and/or poor workmanship work are common causes of rebar corrosion.
Click here for an excellent article by pool engineer Ron Lacher about gunite workmanship issues.


Customers frequently ask if resurfacing the pool will solve the problem. No, it will not.
If the pool is replastered without removing the corroding rebar, the stain will work its way through the new plaster causing a new stain on your new plaster. The corrosion must be removed!

Three stains next to our square. The rebar is rusting through in three areas. If all corroded rebar is not removed, this will occur throughout the pool
