CrawlSpace-DIY - Butyl Tape - 1.5" x 100' - Pack Butyl Sealant Home Repair Tape, Butyl Rubber for Boat Sealing RV Sealant Tape Vapor Barrier Window, Glass Roof Patching - Waterproof

Worked great for our crawl space encapsulation!

Product worked great for hanging crawlspace vapor barrier.

Tape allows for 2 objects to be fastened together with tape.

I've used this type of tape before however I bought this item by mistake it's not used for the intended purpose so I had to return it but I received it quick it was very thick it was well packaged so it seemed like it would not waste it stickiness or become dried out I thought about keeping it but how many uses is there for this stuff? I try not to be a pack rat

I had a constant leak every time my sump pump ran. I wrapped this tape around the sump pump outlet pipe and continuing across the flex pipe. It completely sealed the leak. This tape is great.

I used this tape to re-attach the vapor barrier that had fallen off the previous tape. This was easy to use and cut. the width was great for using the plastic anchors into the concrete.

Does what it is supposed to do.

This double sided tape worked great for encapsulation of my crawlspace. Adhered well to brick and cinder block. Been up 6 months now, will see how well it holds up.
