Here is the honest part first: true HDPE and RPE liners are low-surface-energy plastics that resist glue, and the professional way to join them is heat welding, not adhesive. For a home repair or a seam you cannot weld, a double-sided butyl seam tape is the practical option, as long as you clean and prime the surface and treat the tape as the weak point rather than a permanent weld. Look for a genuine butyl tape that lists HDPE, real width for your seam, and honest expectations.

What are the best alternatives?

With roller

REKVEN Seam Tape Kit (30 ft x 3 in)

The same butyl chemistry in a narrower 3 inch width, bundled with a seam roller and a prep sponge, so you can clean and press correctly. A good pick for patches and tighter seams where the 6 inch tape is overkill.

Long seams

Pond Liner Seam Tape (60 ft x 3 in)

A 60 foot roll of double-sided butyl for joining longer runs in one go. Same caveats apply on HDPE (clean, prime, treat as the weak point), but the length is convenient for a full seam.

Bottom line: for a true HDPE seam, thermal welding wins; when you cannot weld, the wide REKVEN butyl tape is the most credible patch, with the roller kit and 60 foot roll for smaller and longer jobs.
