Why choose us
We are technical specialists with sector-specific knowledge of managing water quality in construction and other industries.
For over 10 years, we have worked with leading contractors and construction companies in the UK and Europe to reduce water pollution in a responsible way. Our innovative technology has been designed to help companies reduce operational costs without harming the environment.
With our award-winning range of silt control products, bubble curtains, water treatment solutions and training programmes, we’re helping industries to improve water quality for all the right reasons.
Increasing compliance
We work with companies to design and implement water pollution management strategies that increase compliance at all stages of a project. For best outcomes, this is done in pre-construction planning but can also be achieved reactively.
Saving you money
Our innovative solutions offer a cost-effective way to manage water quality for the long-term, negating the need for costly mechanical intervention and water treatments further down the line.
Enhancing the environment
Our products are designed to work with the environment rather than against it, using innovative technologies and methods to reduce carbon footprint.
Empowering industries
Enabling people to get better at protecting the environment is what drives us and we share our knowledge through bespoke training, upskilling sessions and hands-on technical support.
Innovation for better outcomes
We use our knowledge and expertise to think beyond conventional methods, leading to the creation of engineered solutions and practices that are better for the environment and better for business.
Tried and tested solutions
Created by industry experts, our award-winning products and methods have been proven in the field, with over 10 years of hands-on experience and applied sector-specific knowledge.
