Ground anchors are what stabilise steep slopes or slopes that are made up of loose soils as well as preventing erosion and landsides. Ground anchors are made up of a bearing plate with connecting cables or rods.

There are many advantages of using ground anchors which consist of reinforced composite materials such as improved durability and therefore less need for maintenance. These ground anchors are much more light weight than conventional steel versions meaning that it is much easier to transport them to the site as well as enabling contractors to place them more accurately. They are much safer to install due to increased tensile strength coupled with them being lightweight.

Composite ground anchors are made up of three parts:
• The composite cable runs through an anchor nut or plate on a steel sheath. This is called the anchorage and it fastens the ground anchor to the structure. Cement mortar fills the anchorage in order to prevent slippage.
• The cable either has just a singular rod or several which are separate or braided together.
• A polyethylene or PVC sheath fits round the free anchor length of cables.
