Silt is the single main pollutant to the water environment from construction sites. Largely, this arises from the erosion of exposed soils by surface water run-off from rain, which carries the silt into public bodies of water such as rivers and reservoirs.
Most construction projects can expect to deal with rain at some point but historically, awareness of silt pollution from construction sites may only have come with a letter from the regulator advising of a pollution incident. This type of reactive approach leads to environmental damage, additional costs and reputational risk.
Construction UK Magazine interviewed us
Our Managing Director Richard Haine spoke to Construction UK Magazine to explain how being ‘rain-ready’ through better planning and a process-driven approach to preventing silt pollution can instead be both cost-effective and reputation-enhancing.

Preparation is key: Silt pollution is a risk year-round
Good surface water management during construction is essential in preventing sediment pollution and minimising risk of prosecution, with the potential for large financial penalties and reputational damage.
Planning silt control interventions is relatively quick and painless. We offer a range of cost effective, low carbon solutions to help prevent risks on site:
- Silt Mat™ – captures sediment and prevents resuspension
- Silt Wattle – reduces flow on sloping ground and in channels & ditches
- Floc Mat® – traps sediment and cleans muddy water using a non-hazardous flocculant
- Silt Net – for placement in lagoons to aid sediment deposition
- Treated Geo-Jute – for polishing water and lining channels
- Rock Check – reduces and distributes water flow in channels
- Gel Flocculant – a low maintenance and non-toxic flocculant used to support silt and water separation to clean muddy water
- Pipe Reactor – mobile water treatment unit
- Bubble Curtains / Bubble Barriers – highly effective at aerating the entire water column and reducing movement of silt in water.
We also offer free training on the risks of silt on a construction site and you can download our Silt Control Toolbox Talk to communicate key points to your team.

“Silt is a highly visible pollutant and is easily spotted. Many of the recent enforcement actions and fines that are being levied have come about from the public submitting video evidence using their smartphones. In recent years, we have seen an increasing focus on the health of rivers in the UK.”
