About concrete cracking
SA HB 84:2018 guidelines
Understanding the complexities behind concrete cracking is imperative; even in well-constructed structures, cracks may emerge. Factors like excess water in the mix, rapid drying, inadequate concrete strength, and the absence of control joints can lead to diverse crack types—ranging from hairline cracks to more concerning settlement or structural cracks—each with its own distinct characteristics and implications.
Moreover, concrete slab cracks, especially prevalent in high-exposure areas like balconies or penthouses, often pave the way for leaks when the waterproofing layer is compromised. These vulnerabilities might stem from natural wear and tear, installation flaws, or errors in construction methodologies.
At DRYWAY, we combine science, experience, and precision to deliver long-term solutions in waterproofing and concrete leaks.
The DRYWAY System
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.

FAQ
Frequently asked questions
Everything you need to know about our services.
Yes. DRYWAY utilises advanced nano-polymer injection technology, specifically designed to provide a permanent solution to concrete leaks, backed by a design life of over 100 years.
The duration of the process varies depending on the size and complexity of the issue; however, most residential projects are typically completed within two days.
Yes. The DRYWAY system permanently eliminates leaks directly at their source, removing the need for external water diversion solutions like drip shields and strip drains.
No. Our minimally invasive process involves precise injection points, significantly reducing the risk of damage compared to traditional methods.
Slab cracks typically develop from concrete shrinkage, thermal movement, ground settlement, and hydrostatic pressure. Once a crack forms, it can become a pathway for water infiltration into the structure below.
DRYWAY injects specialised DWG Nano-Polymer Eco V directly into the crack, where it reacts to create a flexible, permanent seal. This stops water infiltration at its source without requiring floor removal or demolition.
Yes. DRYWAY's DWG Nano-Polymer Eco V injection system is designed to work effectively in wet or dry conditions, including situations where water is actively flowing through the crack at the time of repair.
DRYWAY's flexible injection material is designed to accommodate normal structural movement, which helps prevent re-leaking that can occur with rigid repair materials over time.
You will notice immediate improvements after the injection. In some cases, particularly where the structure is heavily saturated, the full effectiveness becomes clearly visible within 2–3 days, once any residual moisture has dried.
No. Our injection system effectively seals leaks without the need to remove existing waterproofing membranes. Additionally, our product repairs defects within the existing membrane, directly addressing and sealing the true source of the leak.
Yes. Our technology is specifically designed to stop active leaks, allowing us to effectively treat even running water issues during the injection process.
Compared to traditional methods that involve removing tiles, replacing the entire waterproofing membrane, and reinstalling flooring, the DRYWAY system provides a much more affordable and efficient solution. By permanently addressing leaks directly at the source, our process saves you both significant time and money.
The DRYWAY injection system offers a sustainable alternative to traditional waterproofing methods by eliminating the need for extensive demolition and reconstruction. This approach significantly reduces construction and demolition (C&D) waste, which accounts for approximately 30–40% of global solid waste. By addressing leaks directly at their source without removing existing structures, our method conserves natural resources, minimizes landfill contributions, and supports a more sustainable construction industry.
Slab cracks vary in severity. Some are minor surface cracks with limited structural impact, while others extend through the slab and create ongoing water leaks. Professional assessment helps determine the appropriate response for each crack.
Common leak locations include basement floors, underground car parks, balconies, and ceiling slabs in multi level buildings, particularly where water pressure or ground moisture affects the structure.
