About AguaSeal

AguaSeal Waterproofing Systems

AguaSeal Waterproofing Systems was born out of necessity. In much the same way that “mom & pop” shops have become a thing of the past in favor of big-box stores, smaller contracting companies tend to get lost in the wash when compared to the major players in the roofing and waterproofing industry.

AguaSeal is here to service and support all of those smaller contractors, and the big boys too. The amount of time we spend with you before even completing a sale does not matter. We will build a relationship through which you will know who we are, what we do, what we can do for you, and where to find us.
We have deliberately formulated a portfolio of products that we believe will help you maximize your potential revenue stream. The products are custom designed to accelerate your rate of progress on the roof without compromising the quality of your workmanship and jeopardizing warranty requirements.

AguaSeal’s team has decades of experience in the fluid applied industry and is set up to help you in any way possible, including steering you to another product entirely should it be a better fix for the roofing problem.

If you like us, all we ask is that you check out the full range of what we are offering. You never know what’s around the next corner and, perhaps, we could help our businesses grow together.

Meet Our Team

The founding owners of AguaSeal Waterproofing Systems are true veterans of the fluid approved waterproofing systems
revolution that started in the USA in the late 1980’s. Find out more about us below!

Launching an entirely new style of product into a truly well established industry is a bold and major under-taking. Ultimately, it was the infamous Hurricane Hugo of 1989 – with it’s sustained winds of 159mph – that established the concept. While roofs all around Charleston Naval Base were torn off and dumped hundreds of yards away, the one building allocated to the fluid applied system by the Naval Facilities Department stood firm. After the storm had passed, an inspection of the roof revealed not one millimeter of the product had been compromised.

Carl Evans was one of the original founders of Hydro Stop in 1994.

Carl spent many years convincing Facility Managers at US military bases all across the Sunbelt states to give him an audience. He then convinced them to give him a roof, then another… and thus the seed was planted. As those Facility Managers were moved from Base to Base, all across the USA and into the western Pacific, so Carl followed and the roofs continued to be fluid applied.

In 1999 Carl set up operations in Changsha, Hunan Province, China. Since that time Carl has developed new products, always predicated on USA resins and other raw materials, and has stayed true to all of the original Rohm & Haas formulas.

His operation in China flourishes today, importing US raw materials, blending them into the finished product and delivering them all over the vast country for hundreds of applicators. In addition, Carl has developed an international business by providing product to clients from Australia, to the Middle East, to Europe, southern Asia, and has even established another manufacturing plant in Seoul, South Korea.

Carl is a native of Charleston, South Carolina.
