Silt & Debris Bubble Barriers

The Silt Mats worked perfectly, capturing sediment during excavation works of our new channel creation. We really appreciate your flexibility of getting them to us so swiftly.

“With increasing UK rainfall over recent years, and anticipating potential delays, the site was designed with a rain-ready mitigation system to tackle the inevitable surface water.”

“Water is pumped through a Pipe Reactor where it is treated with Gel Flocculant to reduce settlement time, then into settlement ponds and a final polishing pond, which runs over a series of biodegradable mats to remove any remaining silt.”

“The rain-ready approach of using Silt Mats™, settlement ponds and Silt Capture Channels means the equipment remains in place year-round, ready for use whenever needed. Independent laboratory testing has shown that there is 99% reduction in total suspended solids and up to 99% reduction in iron. This means the water being discharged back into the river actually meets the threshold for drinking water standards.

“VolkerStevin contacted us early on in the process, giving plenty of time for discussion and review before the project’s critical works began. It really emphasises what can be achieved with early engagement towards water management.”

“The key takeaway from this project is that it is possible to manage silt pollution to a very high standard with minimal incidents, even across huge scales, varying ground conditions and extreme weather.

“The Floc Mats proved to be a game changer providing innovative silt management. We are now using them on another overhead line project and look forward to the opportunity to work with Frog Environmental again in the future.”

“Frog Environmental were knowledgeable, helping to establish a workable, cost-effective and low maintenance solution for site approved by the regulator.

They really understood the water management issues we had on site and worked with us to develop a solution which works, as well as engaging with our operatives to ensure that they could effectively manage the system.

It was a long regulatory process, but we understand the risks associated with working in such sensitive areas, especially with new and different products and the concerns Stakeholders may have, and they were brilliant in helping provide the necessary data to satisfy Regulator requirements.

We are delighted to have found a solution that prevents pollution and protects the environment, and ultimately allows us to continue with construction.”

“The Bubble Curtain has been a gamechanger for our rivers network and has become an internal success story. Thanks to the specialist support given by Frog Environmental’s Technical Team in design and planning, we got it right the first time.”

The Kex Gill road realignment scheme is a challenging project with multiple environmental risks including management of silt and water quality of the surrounding environment given the locality of designated sites.

Frog Environmental are providing us with extensive technical support, including the design, supply and install of their silt control products on site to ensure the project minimises risks to the watercourses in the project vicinity and prevents impact on highly sensitive aquatic species.

It’s great to be working with them and we’re delighted with the success of the whole project.

It’s good to see Frog getting involved with GT at the earliest stages of the project to help with planning out water management in advance of needing it.

Innovative solutions I’d not considered before.

“The results (of the bubble curtain) were quite dramatic – in fact, startling… we have a workable solution that we’ve proved has a dramatic impact on noise propagation.”

“Thanks to Frog’s technical expertise and insight, we have found new ways to tackle these common issues and improve our site water management practices – from company-wide awareness and training to monitoring and prevention. As a consequence, we have made significant cost savings and lowered our carbon emissions.”
