Advantages of Our Waterproofing Materials

Tunnels can experience leakage due to several factors that compromise their tunnel waterproofing. Understanding the underlying causes can help prevent further damage and improve the longevity of tunnel infrastructure.

Engineered for Durability

Each waterproofing material is formulated to withstand harsh environmental conditions, including hydrostatic pressure, chemical exposure, and thermal movement.

Application Flexibility

Our systems cater to both new builds and retrofitting works, suitable for above- and below-grade structures with varying levels of water ingress.

Superior Crack Sealing and Adhesion

Whether it’s ultra-fine hairline cracks or high-flow joints, our resins and gels provide exceptional sealing performance and strong substrate bonding.

Rapid and Reliable Installation

Most of our waterproofing and injection products offer fast reaction times and long pot life, optimising site productivity and reducing downtime.

Sustainable and Non-Toxic Options

Many of our products are phthalate-, solvent-, and acrylamide-free—ideal for sensitive applications including potable water environments and green-certified projects.

How to Choose the Right Waterproofing Material for Your Project

Selecting the right waterproofing material is critical to ensuring long-term protection and performance for your structure. The choice depends on factors such as the application area, environmental conditions, and the nature of the water ingress. At Tekinject Asia, we guide you through this process, helping you match the right product to your project’s requirements for durability, efficiency, and cost-effectiveness.

Assess the Application Environment

Determine whether your project involves above-grade or below-grade conditions, exposure to constant hydrostatic pressure, or fluctuating groundwater levels. Each waterproofing material in our range is engineered for specific environmental demands, ensuring optimal performance.

Identify the Type of Water Ingress

The severity and type of water ingress—whether minor seepage, active leaks, or high-volume water flow—play a key role in product selection. For example, hydrophilic resins are ideal for dynamic cracks, while hydrophobic foams are suited for rapid sealing.

Consider Substrate Compatibility

Not all waterproofing materials bond equally to every substrate. Concrete, masonry, and soil each require tailored systems for effective adhesion and sealing. Our range includes solutions formulated to achieve strong, lasting bonds with a variety of materials.

Match Performance Properties to Project Needs

Evaluate factors such as flexibility, tensile strength, elongation, and chemical resistance. Selecting a waterproofing material with the right balance of these properties ensures it can handle movement, pressure, and environmental exposure over the long term.

Evaluate Installation Requirements

Some projects require fast-reacting systems for rapid leak control, while others benefit from longer pot life for complex applications. Choosing a waterproofing material with installation properties that align with your site conditions maximises efficiency and results.
