Spray Applied Waterproofing Systems

Protect your commercial and industrial properties with Nusite Group’s advanced spray applied waterproofing systems throughout Toronto and the Greater Toronto Area (GTA). As a leading commercial waterproofing contractor, we deliver seamless, high-performance waterproof membranes using state-of-the-art spray application technology for complex waterproofing projects across commercial and industrial properties.

What Are Spray Applied Waterproofing Systems?

A spray applied waterproofing system is an advanced method of applying liquid waterproofing materials onto surfaces using specialized spray equipment. This cutting-edge technique creates seamless and continuous waterproof membranes on a variety of substrates, including concrete, masonry, metal, and wood surfaces commonly found in Toronto’s diverse commercial architecture.

Spray applied waterproofing systems offer significant advantages over traditional application methods, including faster installation, seamless coverage, superior adhesion, and the unique ability to reach complex or hard-to-access areas that are common in commercial and industrial properties throughout the GTA.

Key Advantages of Spray Applied Waterproofing

Seamless Protection

Unlike traditional sheet membranes, spray applied systems create a monolithic, seamless barrier with no joints or seams that could become potential failure points. This is particularly valuable for waterproofing projects involving complex geometries or irregular surfaces common in Toronto’s commercial buildings.

Superior Coverage

Spray application technology ensures complete coverage of substrate surfaces, including corners, penetrations, and detail areas that are challenging to waterproof using conventional methods. This comprehensive coverage is essential for protecting commercial and industrial properties from water infiltration.

Rapid Installation

Professional spray application significantly reduces installation time compared to traditional waterproofing methods, minimizing disruption to your operations while maintaining the highest quality standards expected from an experienced commercial waterproofing contractor.

Versatile Substrate Compatibility

Spray applied waterproofing systems can be applied to various substrates including concrete, masonry, metal, and wood, making them ideal for diverse waterproofing projects across different types of commercial and industrial properties in the GTA.

Professional Spray Applied Waterproofing Process

1. Comprehensive Surface Preparation

Before applying any waterproofing material, our experienced technicians thoroughly clean and prepare the surface to ensure optimal adhesion. This critical step involves removing dirt, debris, grease, oil, and any loose particles from the substrate surface.

For commercial and industrial properties in Toronto, we often encounter challenging surface conditions that require specialized preparation techniques. In cases where improved adhesion is necessary, we perform surface profiling or controlled roughening to create the ideal bonding surface for long-lasting waterproofing performance.

2. Professional Priming Applications

Depending on the substrate type and specific project requirements, our team applies high-quality primers designed to enhance adhesion between the waterproofing material and the substrate. This ensures a strong, durable bond that can withstand Toronto’s harsh climate conditions and the demanding performance requirements of commercial and industrial properties.

The primer selection process considers factors such as substrate porosity, environmental conditions, and the specific waterproofing system being installed, ensuring optimal performance for each unique project.

3. Precision Spray Application

Using state-of-the-art spray equipment including high-pressure spray guns and specialized airless sprayers, our certified technicians apply the waterproofing material in precise, even layers. This professional application ensures complete coverage and uniform thickness across the entire waterproofed surface.

The spray application process is carefully controlled to achieve the specified thickness requirements while maintaining consistent quality throughout the installation. Our equipment and techniques are specifically selected for the demands of commercial waterproofing projects in the GTA.

4. Multi-Coat System Installation

For enhanced protection and durability, many waterproofing projects require multiple coats of spray applied materials. Each coat is applied according to strict manufacturer specifications and timing requirements, ensuring proper inter-coat adhesion and optimal system performance.

Our experienced technicians monitor environmental conditions and curing progress to determine the appropriate timing for subsequent coat applications, guaranteeing the integrity of the complete waterproofing system.

5. Controlled Curing Process

After application, the waterproofing material undergoes a controlled curing process to form a durable, flexible waterproof membrane. Curing time varies based on environmental factors such as temperature, humidity, and the specific materials used in the system.

Our team carefully monitors the curing process and protects newly applied systems from premature water exposure or mechanical damage, ensuring optimal performance for the life of the installation.

6. Comprehensive Quality Control

Following complete curing, our quality control specialists conduct thorough inspections to verify that the installation meets all project specifications and quality standards. Any areas requiring additional attention are promptly addressed to ensure complete waterproofing integrity.

This rigorous quality control process ensures that every spray applied waterproofing project meets Nusite Group’s exacting standards and provides reliable, long-term protection for your commercial or industrial property.
