“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.

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

They (Frog Environmental) were efficient in providing advice and the most appropriate product for our project. The team responded promptly to ensure the Bubble Curtain was delivered to the site on schedule.

It has worked well and has been great on site. We are demobilising this week, and the bubble curtain is already in store at our next site for reuse!

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.
