Working in Water
Helping contractors to prevent pollution while working in rivers and aquatic environments
Our pollution control products and strategies are designed to help contractors not just work in water, but to work with water.
We understand that working in and around water is complex, and that fast-changing conditions can turn even a small disturbance into a major pollution incident.
Effective pollution control is about process, planning and long-term strategy, rather than quick fixes, using innovative products such as bubble barrier technology and silt control – read more about how we help contractors navigate the challenges of working in water in our Knowledge Hub.
Sound Attenuation Bubble Curtains
- Underwater noise and vibration control, mitigating sound from piling, dredging, and construction activities
- Protects fresh water & marine life, minimising acoustic disturbance to sensitive species
- Does not block navigation, allowing vessels to pass freely
- Flexible deployment that easily adapts to varying depths and project needs
- Process driven and design led solution
Aeration Bubble Curtains
- Lightweight, modular design allows quick setup in urgent situations
- Fine microbubbles restore dissolved oxygen levels fast, stabilising water quality
- No submerged moving parts means low risk of mechanical failure and minimal maintenance under pressure
- Bubble aeration systems can be adapted to various water bodies or emergency site conditions
Water Injection Dredging Bubble Curtains
- Enhances dredging efficiency by keeping fine sediments suspended and improving water injection flow
- Reduces resettling by preventing silt from quickly settling back onto the bed
- Cuts operational costs by minimising repeat dredging and optimising equipment use
- Non-intrusive,flexible and safe to use, making it easy to deploy in busy harbour environments
Litter & Weed Control Bubble Curtains
- Creates a dynamic barrier with rising bubbles blocking and redirecting floating debris
- Non-intrusive solution that allows fish passage and does not harm aquatic life
- Does not hinder navigation so vessels can cross without obstruction
- Low-maintenance & scalable and can be easily adapted for rivers, harbours, or industrial sites
Silt Mat™
- Cost effective silt pollution control on site
- 100% biodegradable for easy disposal or seed onsite
- Can be used on land, in ditches, streams or rivers
- Unique heavy-weight design delivers longevity on site
Silt Wattle
- Traps sediment, slows runoff and captures soil
- Flexible enough to work on slopes and uneven ground
- Quick to install, lightweight and easy to place
- Offers a cost-effective silt and erosion control option
Silt & Debris Bubble Barriers
- Controls sediment plumes, preventing silt and debris spreading in water
- Protects habitats by shielding sensitive aquatic life and ecosystems
- Creates a flexible silt control barrier that is designed to adapt to varying water depths
- Quick to deploy and remove without inhibiting navigation
Abstraction and Asset Protection Bubble Curtains
- Reduces intake clogging by keeping debris, silt, and weed away from pumps and screens
- Reduces maintenance by minimising downtime and costly cleaning of abstraction systems
- Dynamic barrier allows continuous flow and protects without restricting water movement
- Non-invasive design that is safe for fish passage and does not hinder navigation
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.
