Trough repair suggestions

[Dave95602]

Not sure if this is the correct forum for this question.

Our pool spills into a tile lined trough. The trough leaks about 125 gallons a day.

It appears the tile in the bottom of the trough is the culprit as we have tested all the other connections going to/from the trough. Poking around I found some loose/cracked tiles, and the substrate below is soft. When the trough is isolated/drained, water is coming back up in this spot.

Wondering if the best way to fix this would be to raise the drains, pour a new concrete layer over the existing bottom and plaster? Other suggestions?

thx, Dave

With the substrate being soft, adding concrete on top of it would not make that new base any more stable.
Removing the substrate until a solid base material is found and then rebuilding the trough would be another way to accomplish this. This may end up completely removing the trough and replacing it with all new material.
The fact that water is being pushed back into the trough is concerning and this water would need to be completely removed and dried before any reconstruction can occur.

Be careful, water seeping back up like that indicates soil saturated with water. Bad stuff can happen to the pool with a condition like that.

Thanks for the comments. Yes, I agree that the compromised substrate will need to be removed, hoping that is only in one or two spots and not too deep, but we'll see. Once it stops raining here I will do some more checking and dewatering. This leak has been ongoing for some time, so I imagine it will take a while to dry out.

Looks like we are getting more rain later next week also.
