Salix were brought in as specialist contractors to help deal with an exposed pipeline in a river near Johnstown, Carmarthen.

Two trees growing on the river bank had dramatically narrowed the river, impacting the flow and created a large scour pool directly over the pipeline.

Salix went on site and did a full geomorphological and ecological survey of the site and recommended the site was dewatered whilst the pipeline was moved to a more stable channel crossing point.

Salix’s Rock Rolls, erosion control coir matting and pre-planted Coir Rolls were used to ensure the riverbanks were protected from erosion.
