Waterproofing Services for Commercial Buildings

Over the years, buildings with porous exterior masonry substrates become susceptible to contaminates in our air and build up on the masonry substrate as it’s often porous and easy to adhere to.

Some common contaminant examples are carbon, mildew, atmospheric dirt, and rust. These contaminates are removed to achieve a more aesthetically pleasing appearance of the building as well as increased safety of its inhabitants.

Cleaning the substrate is a mandatory first step when it comes to properly sealing or waterproofing the building. There are a number of hard surface cleaners on the market which can easily cause confusion. Please contact Major Painting to schedule a site visit to advise regarding which masonry surface cleaners and methods are best for your building situation.

Exterior vertical masonry substrates can be sealed or waterproofed by using clear water repellants or coatings. These sealers and coatings offer different benefits, and, as a result, it’s very important to express and review the performance you’re expecting from these products for your building.

Clear sealers are often used when trying to preserve the brick aesthetics of the building while keeping light to medium water out. Whereas coatings may be used when trying to change the appearance of the building and keep light water out. Both products have specific pros and cons, and our team at Major Painting will make sure we consult and understand what the end users’ performance expectations are to determine the best strategy.

Expansion joints are an essential part of your building as they allow your building to expand and contract without damaging the concrete slabs on either side of them. To learn more, please visit the caulking page on our website.

Looking to prolong the life of your concrete parking lots, dock areas, or sidewalks, as well as defer the expensive concrete replacement costs? Let us help you get the most out of your concrete by applying breathable sealers that penetrate your horizontal concrete surfaces, sealing it from the inside out. These sealers are great when it comes to pro-longing the life of the concrete because they minimize the ability of harmful elements, such as salt and water, that lay on your concrete and break it down over time. If these harmful elements penetrate your concrete, it leads to rusting of your interior rebar, eventually leading to cracking and spalling that allow more penetration of these elements, inevitably leading to a total replacement of the concrete.

Similar to vertical expansion joints, horizontal expansion joints are designed to allow for the concrete slabs to move without damaging each other. We have a number of products that are great for theses horizontal expansion joints. Please reach out to the team and Major Painting to review your project and find the best product solution for your scenario.
