Waterproofing Flat Roof Buildings

Flat Membrane Roofing is a popular choice for many commercial, industrial, and warehouse structures due to its sleek design and functionality. However, these roofs, while aesthetically pleasing, can sometimes become leaky if not properly maintained. Nusite Group offers specialized waterproofing services tailored for flat roofs, ensuring they remain watertight and durable.

Our waterproofing also extends to green roofs, where the combination of vegetation and roofing requires a delicate balance of waterproofing to prevent any potential damage. Whether you’re dealing with a leaky commercial building or looking to enhance the longevity of your industrial structure’s roof, our team is equipped to provide the best waterproofing solutions for flat roof buildings.

Warehouse & Industrial Building Waterproofing

Warehouses and industrial buildings are critical assets for many businesses, and their structural integrity is paramount. Nusite Group specializes in foundation waterproofing for these commercial properties, ensuring that both the building walls and the foundation remain impervious to water damage. Whether it’s a garage roof in need of sealing, a parking structure requiring an efficient drainage system, or an expansive warehouse floor that demands a robust waterproofing system, our team has the expertise to deliver.

With a focus on longevity and durability, our solutions are designed to protect warehouses, industrial buildings, and parking structures from the challenges posed by water infiltration, giving property owners peace of mind.

Interior Waterproofing

While exterior waterproofing is crucial for preventing water infiltration, interior waterproofing plays an equally vital role in managing and redirecting any water that finds its way inside. Nusite Waterproofing offers comprehensive solutions, including sump pump installation, to effectively manage and expel water from building interiors. Our expertise in weeping tile systems ensures that any accumulated water is efficiently redirected away from the foundation.

We also specialize in weeping tile installation, a proven method to prevent water buildup around the foundation. Foundation cracks, often a sign of water damage, are expertly addressed by our team, ensuring the structural integrity of the building remains uncompromised. With Nusite Waterproofing, you can be assured of a holistic approach to interior waterproofing.

Basement & Foundation Waterproofing

For our commercial clients, we offer a comprehensive suite of services, from foundational repairs to specialized basement waterproofing in Toronto. Here’s a glimpse of the commercial basement waterproofing solutions we provide:

ICF Waterproofing – Collaborating with custom home builders and other partners, we specialize in waterproofing properties still in the construction phase, particularly those with insulated concrete foam (ICF) installations.

Blindside Waterproofing – Recognized as pre-applied basement waterproofing, this method is ideal for commercial properties in the early construction stages, especially those with zero-lot-line foundations or other situations that make post-excavation challenging.

General Basement Waterproofing – This service is highly sought after by custom home builders and architects working on individual or dual properties, ensuring the basement walls remain impervious to water infiltration.

Wall & Floor Crack Repair – Our team of experts adeptly handles crack repairs, regardless of complexity. We assess the extent of foundation damage and suggest the best remedy, from sealing basement cracks with epoxy injection to advanced techniques like crack stitching.

Additional Waterproofing Services – We cater to a range of other needs for our commercial clients, encompassing drainage system setups, catch basin installation & upkeep, sump pump installation & maintenance, and addressing basement leaks.

Exterior Waterproofing

Exterior waterproofing is the first line of defense against water infiltration, and Nusite Waterproofing offers a range of solutions to ensure buildings remain dry and damage-free. One of our effective methods includes the installation of french drains, designed to divert water away from the foundation, preventing potential seepage. For structures with intricate designs or unique challenges, our Bathtub Waterproofing Systems provide a robust barrier against water, ensuring the building’s exterior remains impervious to moisture.

Additionally, in situations where traditional waterproofing methods may not be feasible, our Blind Side Waterproofing technique offers a reliable solution, ensuring protection even in the most challenging scenarios. With Nusite Waterproofing, exterior waterproofing is handled with precision and expertise.
