Our Company

Sealco Ltd head office and warehouse is based in Christchurch, with outlets nationwide through our network of qualified installers. We have an experienced director of the company based in our Christchurch branch who has practical experience on the intstallation, manufacturing, specifications and sales of all of our waterproofing products and systems. Our staff are also trained to provide you with the best solutions available to your waterproofing needs.


At Sealco Ltd, we understand that one of the major challenges for designers, engineers and construction companies alike is to protect buildings from the damaging effects of water. Our philosophy recognises that while waterproofing protection can be a relatively minor component of overall construction costs, it is a vital ingredient to successful project completion and determines the building's longevity. We also understand that our stakeholders are looking for "tried & true" systems, and that one of the critical ingredient of any system is the installation.


Our Service

Our staff are keen to work with you at all stages of your project. We will work with you from the design, including the development of the specification and installation details, right through to system installation. Our aim is to work toward achieving the most durable solution for your application.


We also work extensively with the applicator and main contractors on site, to ensure that our installation standards have been met. We have a comprehensive on site quality management system for each and every application we market. This ensures the highest quality at all stages of your project.


E-mail your specific requirements to us direct: admin@sealco.co.nz. We would also value your comments and feedback.


Our Vision

"To be recognised as being superior in protection"



Protecting our customer's buildings from the damaging effects of water is our primary focus. Our aim 
is to provide competitive, value for money solutions without cutting corners, or compromising the technical integrity of the system. We offer a complete range of waterproofing membrane systems, backed up by professional service and sensible warranties.



Our Warranties

Our systems are fully warranted and comply with the NZ Building Code and the new E2/AS1 requirements. Our applicators, together with the main contractor, work though the installation process using our on site quality control process, and Waterproofing Systems staff are available for final sign-off, checking to ensure that the system has been laid strictly in accordance with the specification. On completion of the project, we issue a comprehensive warranty.
