Waterproofers are responsible for applying sealants, coatings, and other waterproofing materials to surfaces in order to prevent water from penetrating and causing damage. They may also be tasked with inspecting these surfaces after the waterproofing process is complete to ensure that it was done properly.

Cleaning and preparing surfaces for application of sealants, coatings, or other waterproofing materials; inspecting roofs and other structures to identify leaks or damage that may require repair before applying a waterproofing product; applying waterproofing materials to structures such as roofs, concrete slabs, foundations, balconies, or decks; inspecting the material after installation to ensure that it was applied correctly; cleaning up spills/splashes that may occur during the application process; coordinating with architects on design decisions related to waterproofing materials; inspecting the condition of existing waterproofing materials as needed to determine when they need to be reapplied; applying liners to walls or floors, e.g. in wet areas such as bathrooms, to prevent water from seeping into areas where it is not desired such as inside wall cavities or underneath floors.
