Our versatile waterproof roofing contractors on Oahu can perform above- and below-grade waterproofing for commercial, industrial, and residential clients. Because every project presents a set of unique challenges, our team knows how to apply the waterproofing and protective applications that are the perfect fit for your property.
Every job we perform is different, but we perform our work in a number of stages to ensure the best end-result that lasts for years to come.
Assessing the Scope of the Work
Before we start work, we send out one of our experienced waterproofing contractors to assess the damage and determine the source of leaks. After this assessment, we’ll inform you of what needs to be done, potential problems, and which available waterproofing options are best for the job.
Cleaning the Surface and Substrate
The first step in the waterproofing process is to thoroughly clean the surface and the substrate to enable the liquid applied membrane to adhere adequately. Depending on the scope of the damage, we may pressure wash the substrate to clean it and remove any debris, dust or other elements that may compromise the adhesion.
Once the surface and substrate are cleaned, we apply a primer to the surface to enhance the adhesion of the membrane. The purpose of this is to prevent bituminous oils from bleeding through to the membrane. Because this step requires a dry environment for the primer to adequately dry, our technicians may use torches or an air blower to speed up the drying process.
Addressing the Roof’s Details and Components
Before applying the liquid membrane, our technicians address the details and components of your roof using spot treatments, caulking, and installation of waterproofing elements. Some of the most common areas we address include:
Application of the Liquid Membrane
Many liquid membranes need fabric reinforcing mats installed underneath before installation, so we install this before applying the liquid membrane. This ensures a cohesive finished product that creates an impenetrable barrier against moisture while also preserving energy-efficiency throughout the building. After the liquid membrane is set, we install the other roofing elements on top of the waterproofing materials.
Final Inspection & Cleanup
Once the membrane is applied and the roofing materials are installed/re-installed, our technicians inspect the finished product to ensure that every leak is eliminated. We will also begin cleanup so that there are no leftover materials at the jobsite.
