Everything I would need to do this project was in this box other than a caulk gun. I was immediately impressed. I would definitely recommend this and would buy again if needed. Maybe not the neatest job that has ever been done, but it is going to work great!

Instruction booklet only marginal. Photos hard to see. Print is tiny etc. etc. Included two part epoxy is not quite enough to cover a 10 foot crack to the specifications they recommend.

It is holding so far, only one heavy rain. The need to explain the application of the mixture of A and B needs to be more about the importance of no holes.

Ran very low on epoxy for an 8 foot crack that was 1/4 inch at the widest. Used 99% of the urethane injection. Hope it stops the leak.
