Spirafix ground anchors are used when a loading needs to be secured for permanent, temporary or semi-permanent applications. The installation and removal is extremely easy, which makes them ideal for all different ground types and provides cost and time savings for prospective projects. Our anchors are used for a multitude of applications, please check out our Projects page or alternatively get in touch with our team to discuss your application.
To understand a bit more regarding installation and removal please see below some points, which will help when using the Spirafix anchor. If you require Spirafix to undertake the installation, please feel free to call our sales team to book our on-site service.
Spirafix ground anchors use the same method of installation and removal whatever the size of anchor, which is impact driven to install and counter rotated to remove. Whenever installing Spirafix anchors please check for buried services prior to install.
Using a sledgehammer or lump hammer, along with a manual hammer cap installation is achieved by impacting the anchor into the ground, we recommend multiple moderate impacts versus heavier larger impacts to allow the anchor to rotate into the ground with each impact.
Suitable for 30, 40 and 50 mm anchors
Minimal equipment required for install.
Great for remote locations
Appropriately sized hammer cap SA491 - 30mm anchors SA492 - 40mm anchors SA493 50mm anchors (placed over head of anchors to protect anchor head from damage)
Sledge hammer required for 50mm anchors
Lump hammer for the 30mm and 40mm anchors
Handheld Mechanised installation
We would recommend the use of handheld mechanised equipment when installing large anchors or multiple small anchors. When using equipment for the installation of Spirafix anchors it is important to ensure the hammer cap of the machine is perpendicular with the collar of the anchor. This optimises install and preserves the life of the ground anchor.
Suitable for installation of anchor sizes up to SF75-12-1320AC
