Liner adhesive

[Whozurdadi]

Hi everyone! I'm excited to have joined the forum and looking forward to learning from you all, which brings me here in the first place. I have a smaller pond approx. 6'x7'x1.5' with a waterfall. I'm putting in a rubber liner but I need to adhere the liner on the back half to prevent water from getting under the liner. I only have to worry about the back half because the other side will be under cap stone. I tried a landscape adhesive but after 12hrs it didn't hold. It had a 1 hour cure time. I need assistance finding a good adhesive that is waterproof and will adhere to both cinder block and natural stone. Any assistance would be great! Thank you in advance!
