Below Grade Tanking

Empowering agribusinesses with cutting-edge consulting in precision farming, automation, and sustainable solutions.

Below-ground waterproofing, also called below-grade tanking, is a waterproofing system for residential, commercial and civil projects. The purpose is to protect structures from water ingress, ensuring long-term durability and structural integrity. Our expertise covers both pre-applied and post-applied solutions, regardless of scale or location.

Ideal for challenging below-ground environments

We work with proven, industry-leading systems, including bentonite waterproofing (e.g. Voltex, Swelltite), torch-on membranes, HDPE systems (e.g. Proofex Engage) and bitumen-based products (e.g. Bituthene, WPM3000x).
With a comprehensive range of technologies and decades of application experience, we deliver below-ground waterproofing solutions that protect buildings and infrastructure from the ground up with a focus on compliance, reliability and performance in challenging below-ground environments.
