Penetration Sealants

Sealants for flat roof penetrations

PocketPro is used for sealing flat roof penetrations that are particularly challenging. 

PocketPro is manufactured from polyurethane elastomer, which absorbs stress and remains flexible. The PocketPro can be assembled on site and should be filled with a solvent-free multi-use sealer, making it watertight within minutes. 

PocketPro is available as a pre-formed product, kit form or as individual components. It's quick and easy to install, saving time and money.



PocketPro Complete Sections

The PocketPro is available as pre-formed elements for simple site assembly prior to being filled with the PocketPro liquid.
