  • Manufactured from high quality steel sheathed in a tough polyethylene material. 
  • Designed for maximum grip in a variety of soil conditions. 
  • Has a cadmium plated bullet point tip for accurate precision allowing it to be driven into the hardest of soils. 
  • The polyethylene sheath is deeply ribbed with a series of barbed anchors to give a firm anchor in the ground. 
  • Overall diameter of the ribbed marker is 22mm. 
  • The yellow head is manufactured from high impact polyethylene resistant to high temperature changes and UV radiation. 
  • When installed the head becomes an integral part of the spike ensuring greater stability. 
  • Site data can be marked onto the head with a special marker pen. 
  • Flat Head: 100 x 100 x 20mm giving an almost flush fitting marker. 
  • Alternatively the solid aluminium reversible pyramid head from the Perma-Mark can be used. 
  • A special sealing cap is provided with each Ground-Mark which has concentric rings and a plumb point recess in the centre allowing for accurate alignment of prism poles instruments etc. 
  • No special tools needed: Simply place the marker head in the desired position and drive the Ground-Mark through the head with a standard lump hammer all that remains is to knock a special sealing cap onto the head of the Ground-Mark... Job finished!
  • Available in two sizes: 300mm and 500mm.
