In 2019/20 works were undertaken to prolong the life of the promenade structure and adjacent shoreline at Aberavon. The implementation of the Shoreline Management Plan has served to protect residential and commercial properties from coastal erosion. Geofabrics HPS11C is a thick needlepunched non-woven geotextile manufactured from 100% virgin polypropylene high tenacity fibres containing 1% active carbon black. The main function of HPS11C is to prevent loss of the sub-soil from below the rock armour. With challenging low particle size subsoils, the HPS11C was ideal with its combined filtration and permeability characteristics.

CuTex is a permeable geocomposite root barrier consisting of a copper sheet mechanically encapsulated between a woven polypropylene geotextile and a high strength nonwoven polypropylene geotextile. Cutex functions not only as a physical barrier, but also as a chemical barrier.

Japanese knotweed was identified on a site where refurbishment was due, including small extensions to the building and new paving to the outside space where Japanese Knotweed was located Following a limited level excavation to remove most of the knotweed rhizomes in the soil, CuTex composite root barrier was installed horizontally and vertically to cap any remaining rhizomes.

Geofabrics HPS17 is installed as the protection geotextile at Erin Landfill Site, a former colliery near Chesterfield. The geotextile formed part of a large cell measuring approximately 40,000m². The site also involved installation of 1000m of deep water drainage, 118,000m² of impermeable membrane, 1000m of fully-welded leachate pipework and 14,000 tonnes of drainage stone. Geofabrics HPS17 is a thick needle punched non-woven geotextile manufactured from 100% virgin polypropylene high tenacity fibres containing 1% active carbon black.

A new terminal at the Port of Cork will provide a 360m quay enabling larger ships to berth in Ringaskiddy, accommodating current and future container shipping. Geofabrics HPS6, a needle punched nonwoven geotextile was installed by BAM as a filter preventing displacement and erosion of submarine soils.

Geofabrics HPS5 was successfully installed below the rock armour on the River Aire’s flood plain. Geofabrics HPS5 is a thick needle punched nonwoven geotextile manufactured from 100% virgin polypropylene high tenacity fibres containing 1% active carbon black. The main function of HPS5 is to prevent loss of the subsoil from below the rock armour. HPS5 was ideal with its combined filtration and permeability characteristics whilst its high tensile elongation and CBR provided a robust solution capable of withstanding the rock impact during installation.
