Balcony Waterproofing System

Simplify balcony and breezeway installation with Tamko's lineup of waterproofing products.


Tamko’s waterproofing products – which include primers, membranes, flashings, and mastic – are well-suited for waterproofing balconies, breezeways, and other wood-framed structures. The company says that their TWP-1 and TWP-2 primers can be used to prep OSB sheathing prior to installation of their TW-60 sheet waterproofing membrane and TW-105 flashing in above-grade applications, and can eliminate the need for corner metal flashings when used in combination with each other. Their TWM-1 is a trowel-grade rubberized bitumin mastic that can be used to patch seams, overlaps, and membane terminations. Tamko.com.
