Slab Drains & Core Holes
Precision Sealing for Slab Drains and Core Holes
Why are slab drains and core holes common sources of water leaks, and how can DRYWAY help?
Slab drains and core holes are essential elements in your building’s drainage system, crucial for effective water management. These points, where waterproofing membranes typically end, are particularly vulnerable to water leaks.
Traditional repair methods in these areas are often costly, disruptive to occupants due to the need for removing floors and finishes, or inadequate solutions that merely hide the issue with drip shields. Persistent leaks can cause not only aesthetic damage but also foster mold growth and produce unpleasant odors, significantly compromising the comfort and health of residents.

The Breakthrough 4-Pillar System

Truly Customised
Methods Statement
A dedicated engineering team meticulously analyses and defines the most appropriate methodologies for every new project. This involves careful considerations of drilling locations and techniques, packer choice, estimated material volume, pressure limits, and reaction time. All these crucial aspects are thoroughly discussed and precisely instructed before commencing any work, ensuring a comprehensive understanding and seamless execution.

The Most Advanced Equipment
The new “DWG JetFlow e-Twin 23” electronic pump, a remarkable solution designed to deliver precise injection of low-viscosity materials. With its advanced control system and custom-designed digital panel, this pump offers unparalleled reliability and versatility. Whether in clean penthouse applications or in a rough underground construction sites, the “DWG JetFlow Ev-Twin23” excels in diverse conditions.

Signature Materials
Our signature material “DWG Nano-Polymer Eco V”, an ultra-low viscosity flexible liquid designed to permanently eliminate water leaks. It’s injected electronically and travels in the opposite direction of water until it reaches the source of the leaks. Once in place, our technology triggers a non-expansion chemical reaction that transforms the nano-polymer into a rubber base hydrophilic substances impregnated in the porosity of the elements, sealing all water paths.

High Experienced Application Team
Every service is as good as who is implementing it. Our team’s success is driven by their high level of expertise and extensive experience. Composed of certified professionals in waterproofing and engineering, they ensure excellence in every project, no matter the complexity.

What our clients say
“At Metro Trains Sydney we face a number of challenging situations as we have station boxes built into the rock walls and sub-formations to connect the Tunnels running underneath Sydney to the surface. The ground and rainwater likes to run off where it can and find its way into LV rooms, Lift Shafts, Ventilation ducts to name a few with Dryway being the company MTS relies upon to manage the water leaks. What strike me with Dryway is the ability to address the issue first time around, no rework, no additional shifts………working with Bruno and Team is a pleasure as they know what is required to make long term repairs.”
Calvin Klinkenberg
Maintenance Delivery Manager - Track
“Over the years, I have had the pleasure of engaging Bruno and his team at Dryway. Their extensive experience and deep technical knowledge have proven invaluable in addressing the complex challenges within our tunnel environments. Bruno consistently delivers innovative and practical solutions, applying a scientific and cost-effective approach to water infiltration issues. His ability to assess problems thoroughly and implement effective strategies has significantly contributed to the long-term integrity of our infrastructure. I highly recommend Dryway for any organization seeking reliable and expert support in managing water infiltration challenges.
Jason Quarta
