Spillway repair question

[jolson311]

Over the winter we had some stone break away from the sides of the spillway from the spa to the pool. There were some micro cracks last year and it appears water got behind and popped a section loose during a freeze/thaw. See pictures below.

Wondering how something like this would be repaired? Can I scrape away the loose stone and seal the area? Does it need to be removed and replaced? If so any recommendations on folks to do this type of work in the DFW area?

The pool is about 20 years old and was completely remodeled 5 years ago. I believe the stone was a lueders stone. Starting to see some wear on the coping around the waterfall and was also wondering if that could/should be sealed with anything to prolong the useful life.

Appreciate any guidance or thoughts yall have.

Good morning! Repairing the side of the spillway shouldn't be a terribly difficult job with the proper materials. From the pics it would seem questionable as to whether the stone that popped off or the remaining ones are salvageable. Ideally you would want some clean edges to mate-up to each other. While I'm not familiar with contractors in the DFW area, I'm sure we can give you some tips to get prepared. I suspect a proper cleaning/prep of the base followed by a good thin-set material to get the stone to adhere in place. Lastly, grout to seal the edges.

Let me tag @AQUA~HOLICS who may be able to clarify some key things to watch for about the repair process. We can also ask @Jimrahbe if e knows of anyone in the DFW area who does such work.

I would suggest removing the old product until you can get to clean unexposed to water damage base material, often times when water damage occurs in spillways it’s more wide spread than expected. This is how it’s repaired and not temporary patched.

In pictures 3&4 the coping is weathering, possibly from material weakness. I’m not familiar with sealing coping as it’s not a common practice that I see done in my area.

The last picture shows movement of the deck work that is applying pressure to the coping, of all the pictures provided this one concerns me the most because it could be a early sign pressure on the bond beam, possibly from the two not being independent of each other.

Thanks for the replies! Is there anything that can be done to this type of precast coping to protect against weathering? Also, are there other signs that I should look for on the last issue you mentioned as more concerning? Happy to provide additional pictures as needed. Appreciate any insight yall can provide!

The copings I am familiar with do not get sealed, so I don’t have an answer for that.

What is concerning to me is picture #6
This crack is long, it follows the joint from one side to the other and goes straight through the coping, from the picture provided unable to determine if it follows the radius around completely on the face.
This is comm to see when there is a horizontal pressure being applied to the deck (typically from heat expansion) and the coping is cracking from the movement.
This typically only gets worse and the movement becomes larger as time goes on.
