Who We Are

Trading since 2009


At Waterstop Solutions, we pride ourselves on providing excellent remedial waterproofing, industry-leading concrete crack, leak sealing injections and concrete repair solutions, with a solid reputation for integrity built upon years of reliable service in the building and construction industry.

The key to our quality workmanship is knowledge, experience, support from our partner suppliers, consultants and documentation. We work very closely with our suppliers and consultants to ensure we achieve the best results.

Our passion for delivering exceptional service and workmanship had led us to the forefront of our industry, becoming a highly respected and sought-after entity.

Driven to expand into Australia’s largest remedial market, we now have offices located in Brisbane and Sydney with further expansion planned for the future.



Our Mission


At Waterstop Solutions our goal is to provide innovative, flexible and practical solutions to ensure the best possible outcomes for our clients.

We aim to deliver exceptional service to build and maintain long-term relationships with our customers.


Executive summary


Waterstop Solutions is committed to providing a high standard of service. Together, our Directors Harold Du Toit, Chris Anderson and our NSW Manager Adrian Schokman share more than 60 years worth of industry-leading remedial waterproofing and concrete repair experience.

The best measure of our success is the “follow on” works from our existing clients.
Our commitment to safety and our impact on the environment always takes first priority.

Our approach to quality is to plan; control; monitor and grow from the outcomes. Quality assurance is a tool for us; the client and the supplier to micromanage the critical elements of their project that ultimately produces an optimal result. With limited training opportunities for our field of expertise in Australia, we have invested in sending our project manager to Singapore, the USA and Germany (recognised leaders in this field) to undergo extensive training. This provides us with the foundation for further development and up-skilling of our Australian workers.

We are a family-owned business established by Harold Du Toit in 2009 to service the construction of the Clem 7 tunnel. Since its inception, Waterstop Solutions and its team have helped grow the company into a well-respected entity. Our enthusiasm and passion help us achieve our goals and expand our horizons without losing focus on what got us where we are.

We strive for excellence in service and ensuring an outcome that will continue to keep our company at the forefront. In early 2011, due to positive growth from the Airport Link tunnel project, we have focused on improving policy and procedures, therefore, ensuring projects are well managed and exceed client expectations.

By law, waterproofing companies in Queensland require only 1 licenced tradesperson. Waterstop Solutions has 8 qualified staff members with a Certificate III in Waterproofing, along with 6 apprentice waterproofers – soon to make a total of 12 licenced Waterproof technicians working for us.

Other team members possess qualifications in Project Management and Business Management.
It is highly uncommon for a company in our field to have so many qualified staff, and this is something of which Waterstop Solutions is very proud.

Waterstop Solutions’ mission is to be the best at what we do, and this has spearheaded our own product development, to continually improve upon what already exists in the marketplace.


To honour our commitment to “Quality Service, Quality Solutions”, Waterstop Solutions developed, and now delivers, an in-house remedial repair training program to all Technicians.

A depth of technical knowledge and experience, along with a proud reputation for integrity and reliability, has made Waterstop Solutions the go-to company for many Defect Managers working for major construction companies across Queensland.

Knowing that the climate of the marketplace can change rapidly, Waterstop Solutions is determined to remain dynamic and perceptive of current trends.  Since the recent slow-down in civil construction across Southeast Queensland, Waterstop Solutions has restructured and refocused to apply its skills-set to a broader market, targeting specialised domestic solutions through to major civil projects.  In this way, Waterstop will provide quality service and solutions to homeowners, commercial operators, civil contractors and more, who wish to “benefit from major civil projects experience” for many years to come.




Waterstop Solutions has policies and procedures in place that are developed to meet industry standards. Constant review and development in the way we conduct our business benefits not only the company, but also our clients and employees. Guided by the health and safety of our employees, our impact and responsibilities to the environment and providing a quality service, we monitor and adapt to accommodate changes that impact us.


The Polyurethane resins we predominantly use (TamPur 130 and TamPur 150) for leak sealing and crack injections have been tested by AWQC for use in contact with drinking water. The Water Potability Certificates for TamPur 130/150  confirm they been product tested for and are compliant with the AS/NZA 4020 and compliant with the latest standard.
