Floc Mat®

A Floc Mat is a geotextile-based treatment system that uses embedded flocculant to remove suspended solids from surface water runoff. It passively treats that water that flows across or through the mat, promoting particle settlement and reducing turbidity.

As water flows over the mat, it comes into contact with slow-release Gel Flocculant that binds fine sediment particles together into larger clumps. These heavier particles then settle out, helping to keep downstream water clear and compliant with discharge limits.

Use Floc Mats whenever activities (construction or otherwise) may generate fine sediments. These activities typically include earthworks, stockpile management, dewatering, or haul road runoff but can extend to conservation, habitat creation or restoration projects. A Floc Mat is particularly valuable where traditional silt control methods alone aren’t enough and treatment is needed to meet discharge quality standards.

Yes, our Floc Mats are designed to be environmentally responsible. They are 100% biodegradable. The flocculant is securely embedded in the mat and released in low doses, minimising risk. The materials used are non-toxic, and the mats can be safely removed and disposed of at the end of the project – or left in-situ to create a natural habitat.

If you are discharging treated water to a surface watercourse or drainage system, you may need a discharge permit or consent from your local environmental regulator. We recommend checking with your regulator before installation but will talk you through the process when you make an enquiry.

Yes, Floc Mats are simple to install and come with clear guidance. They are designed for quick deployment by site staff and can be anchored with sandbags or stakes. Visit our installation section for more detailed information or contact us for support. We can also supply you with a list of approved installers.

A Floc Mat will generally remain effective for three months but increases in sediment loading will shorten this period. Conversely, if there is little sediment in the water to be treated this can lead to a longer life span.

Absolutely. Floc Mats are most effective when used in conjunction with other site-specific measures, in fact our Silt Capture Channel is formed using a combination of our products including these mats. Our team can recommend the best combination for your project.

Yes. We regularly support clients with on-site assessments, installation advice, pollution prevention training and compliance planning. Contact us to arrange a visit or speak to one of our technical specialists. We happily provide practical advice and support to ensure the right product is used effectively.

• In-ditch Polishing Point: consists of just Floc Mats, Silt Mats and Silt Wattles for a capturing and separating silt from flowing water. It is designed to ‘polish’ the water rather than our other treatment alternatives better designed for bulk drop out.
• In-ditch Treatment Point: includes the use of Gel Flocculant to bind fine silt particles to treat the water, as well as our mats which capture the suspended material while the surface water flows over them.

Maintenance is minimal but important. Inspect mats weekly or after heavy rainfall to ensure they are correctly positioned and not clogged. Replace if water clarity starts to decline.
