I address spillway leaks with clay/polymer layers compacted by hand and with the few projects completed they were successful. If you prefer using bentonite I suggest the same method, high plasticity clay layers and bentonite compacted to achieve a seal. Anti seep collars are always strongly recommended. If you want to reach out to discuss I’m happy to chat anytime.
