Good afternoon all! Need some professional input. I’ve got a commercial space that has recently had new carpet installed. Building was originally built in 2001, slab on grade, high traffic, existing sheet carpet was still in place prior to recent remodel and was honestly in good shape considering age and use. New carpet is Shaw Ecoworx, and was installed using Lokdots. My issue is the tiles have the adhesion strength of a fresh post it note on each corner. Grab a corner with fingernails and it peels right up. Was this installed properly? Possibly not weight rolled? In my head I’d assume 4151 would’ve been a more appropriate choice. Or maybe I’m overestimating the adhesion strength it should have.

My wife bought some Shaw Ecoworx carpet tiles to cover some concrete in our basement. Based on what I'm seeing on Shaw's online installation guide, I need either their Lokdots system, or their Lokworx tabs.

However...both of these are rather expensive. If I absolutely have to buy the manufacturer's proprietary product to do it correctly, then I will. I can't help but think, though, that someone is making a product that would serve the same purpose, but would be more wallet-friendly. Is this the case? Or am I doomed to shell out the cash and buy the Shaw brand adhesive?
