Water Treatment Solutions
Floc Mat®
Floc Mat offers a fully biodegradable water treatment solution reacting with and capturing silts and sediments. On their own or as part of a larger treatment, Floc Mats can be used to clean muddy water and prevent silt pollution.

Designed and manufactured by us, our unique and environmental-friendly Floc Mat® provides a safe, cheap and easy solution to support the removal of pollutants from the water.
Placed in ditches and channels, as water moves over and through the biodegradable mat fibres they capture and trap silt, clay and other fine sediment naturally. The mats also provide a low-carbon, cost-effective way of treating water without the need for pumps, saving energy and carbon.
Floc Mat comes in untreated or treated forms, with treated versions having a highly effective, non-toxic flocculant impregnated into the natural fibres to aid silt binding performance.
Unique to Frog Environmental, Floc Mats® are commonly used in a variety of ways:
- Construction & infrastructure site treatment ditches and channels with low flows
- Drainage from construction sites
- River restoration and maintenance operations
- Agricultural and forestry operations
- With attenuation ponds and lagoons to improve settlement
- For Infiltration fields to increase a field’s settlement capacity
- Forestry and agricultural operations
- Within Silt Capture Channels. As part of a larger, more comprehensive treatment solution.
