Dan, Red Truck, Ron, and everyone else who has used any type of sealants for water. PLEASE, let me know your thoughts on this.
I have a double wall 48" diameter culvert pipe that I have finally sealed off successfully on one end, only to now find that there is a small slash in it with water coming out. This pipe used to be part of the overflow basin that allowed the water to exit our 6.5 acre pond. Regardless, how do I seal it? DAM-IT seams to be an answer, hydraulic cements, epoxy's specifically for use with water all seam good solutions as well, but the pipe is plastic, so what works best with a plastic double wall pipe configuration with a 1/2"-1" vertical slash in it with water coming out? The biggest challenge seems to be how to get the product injected into the small, not flexible slash where the water is coming out of. It is so small that sticking the stem of a cauck tube is very challenging. Ok, I'll shut up now and await your response. Thanks everyone!
