Aquaseal Basement Waterproofing :
30 Years of Excellence serving Southern Ontario

Established in 1988, Aquaseal Basement Waterproofing is a family owned business that has been a trusted name in the industry. This company has been providing exceptional basement waterproofing services to the residents of Southern Ontario for over three decades. As a company that takes immense pride in its expertise and dedication, Aquaseal has consistently delivered top-notch solutions to protect homes from the perils of water damage and foundation issues.

Exterior Basement Waterproofing:

One of the primary services offered by Aquaseal is Exterior Basement Waterproofing. This essential process involves the application of protective coatings and sealants to the external walls of a basement foundation. By doing so, the company effectively safeguards the foundation from water infiltration and moisture-related damages. Utilizing advanced waterproofing materials and techniques, Aquaseal ensures that the basement remains dry and secure, preventing potential issues such as mold growth and structural deterioration

Interior Basement Waterproofing:

Interior basement waterproofing systems are essential solutions designed to prevent water infiltration and moisture issues in below-grade spaces. These systems are installed on the inside of basement walls and floors, providing a barrier against water penetration from the surrounding soil and groundwater. One common method involves applying waterproof coatings or sealants to the interior surfaces, creating a waterproof membrane that stops water from seeping through cracks and pores. Another approach is the installation of interior drainage systems, such as French drains or sump pump systems, to collect and redirect water away from the foundation. Interior basement waterproofing is an effective way to protect basements from water damage, mold growth, and structural deterioration, ensuring a dry and healthy living environment while preserving the integrity of the property.

Epoxy Resin Injections and Polyurethane Injections:

Foundation crack repair is a crucial aspect of basement waterproofing, and Aquaseal specializes in it. Through the use of advanced techniques like Epoxy Resin Injections and Polyurethane Injections, the company effectively seals cracks and voids in the foundation walls. These injections create a strong, impermeable barrier, preventing water from seeping through and ensuring the structural integrity of the foundation.

Window Well and Drain Services:

A common entry point for water is through basement windows and window wells. Aquaseal Basement Waterproofing offers comprehensive solutions to address this concern. By installing well-designed window wells and efficient drainage systems, the company prevents water from pooling around the windows, thus keeping the basement dry and habitable.

Sump Pump Installation:

A reliable sump pump is an essential component of any comprehensive basement waterproofing system. Aquaseal offers professional Sump Pump Installation services, ensuring that the pump is strategically placed to efficiently remove accumulated water from the basement. This proactive approach significantly reduces the risk of flooding and water-related damages.

Weeping Tile Installation and Cleaning:

Weeping tiles are an integral part of basement drainage systems. Aquaseal Basement Waterproofing installs high-quality weeping tiles around the perimeter of the foundation to redirect water away from the basement. Additionally, they offer weeping tile cleaning services, as these tiles can become clogged with debris over time, hindering their proper functioning. Regular cleaning ensures optimal performance and helps maintain a dry and secure basement environment.

High-Pressure Water Jetting:

Aquaseal's high-pressure water jetting service is an effective method for clearing stubborn blockages in drainage systems and weeping tiles. By using powerful jets of water, the company can dislodge debris and sediment, enhancing the overall efficiency of the basement waterproofing system.

Excavation Work with Mini Excavators and Bobcat Service:

In situations where exterior waterproofing is required, Aquaseal Basement Waterproofing offers professional excavation services. Equipped with mini excavators and bobcats, the company can efficiently excavate the area around the foundation, providing access to the external walls for waterproofing applications. Their experienced team ensures that the excavation process is carried out with precision and minimal disruption to the property.

Dump Trailers:

Aquaseal provides dump trailers for the removal of excavated soil and debris from the site. This ensures a tidy and organized worksite throughout the basement waterproofing process.

Brick Sealing:

Brick sealing is another vital service offered by Aquaseal. As bricks are porous materials, they can absorb water and lead to water damage if left unprotected. Aquaseal applies premium-grade sealants to protect the bricks from water infiltration, thus preserving the structural integrity and aesthetics of the property.

Tie Rods and Snap Tie Repairs:

Over time, tie rods and snap ties used in concrete construction can deteriorate and create vulnerabilities in the foundation. Aquaseal Basement Waterproofing specializes in repairing and reinforcing these elements, ensuring the foundation's stability and water resistance.


Aquaseal is committed to delivering personalized solutions to its clients. They offer professional consultations, where experienced technicians assess the specific needs and challenges of each property. Based on this evaluation, Aquaseal recommends tailored waterproofing solutions that address the individual requirements of their customers.
