Why below-ground tanking design is Important?

Below-ground tanking design is critical for the long-term performance, durability, and safety of underground structures. More than just a protective layer, a tanking system must respond to a range of challenges, including soil conditions, groundwater pressure, and potential contaminants. The importance of below-ground tanking designs lies in its ability to integrate structural, geotechnical, and drainage requirements into a cohesive, high-performing waterproofing solution that safeguards the building and ensures lasting reliability.

Structural Integrity and Water Resistance

A properly designed tanking system must withstand hydrostatic pressure, soil loads, and potential ground movement. Our below-ground tanking designs ensure that the structure is fully protected and integrated with the building’s foundation, minimizing the risk of water ingress and structural damage.

Moisture and Groundwater Protection

Below-ground tanking systems are critical for preventing water penetration into basements, underground car parks, and other structures. We design solutions that provide robust resistance against water ingress, high water tables, and soil moisture, safeguarding the building’s integrity over time.

Durability in Challenging Conditions

Our below-ground designs consider a range of ground conditions, including complex soils, contaminated sites, and fluctuating water tables. By selecting appropriate materials and construction methods, we ensure long-term reliability and reduce maintenance costs.

Integration with Drainage Systems

Below-ground tanking designs are carefully coordinated with structural, geotechnical, and drainage designs to ensure seamless integration and optimal performance. This reduces the likelihood of leaks and supports the overall safety and stability of the building.

Our Approach To Below-Ground Tanking Design

At Symetrix, our approach to below-ground tanking design is rooted in precision, collaboration, and practical expertise. Every site and structure is unique, so every tanking solution we deliver is custom-tailored. We combine technical knowledge with strategic planning to create waterproofing systems that are reliable, durable, and compliant with all New Zealand standards.

Collaborative Design Integration
We work closely with structural engineers, geotechnical consultants, and contractors from the earliest design stages. This collaborative approach ensures that tanking systems are fully coordinated with foundation, drainage, and structural designs for seamless integration.
Performance-Driven Solutions
Our below-ground tanking design process focuses on real-world site conditions, including soil types, groundwater pressures, and potential contamination. We assess system performance under hydrostatic pressure, soil movement, and long-term environmental conditions to ensure durability and effectiveness.
Material and System Selection
With extensive knowledge of below-ground tanking designs and systems (including Type A, B, C, and hybrid solutions) we help clients choose the most appropriate materials and installation methods based on site conditions, design goals, budget, and lifecycle requirements.
Compliance and Risk Mitigation
Our team ensures all below-ground tanking designs meet New Zealand Building Code standards and relevant industry regulations. We perform thorough reviews and risk assessments to identify and address potential issues before construction begins.
Digital Modeling and Simulation
We utilize advanced modeling and simulation tools to visualize system performance, refine designs, and coordinate with structural and drainage systems. This reduces errors, enhances constructability, and improves overall project outcomes.
Quality Assurance and Site Support
Our involvement in below-ground tanking extends beyond design. We provide detailed construction documentation, shop drawing reviews, and on-site inspections to ensure the below-ground tanking design is installed precisely as intended, delivering reliable, long-term waterproofing performance.
