Williams - Grout Bonded Multiple Corrosion Protection Anchor
Williams standard grout bonded rock & soil anchors consist of a plain or epoxy coated bar, grouted in an oversized drill hole. Centralizers should be used to assure good grout cover (approximately 25 mm) around the bar. Where anchors will penetrate aggressive soils that are low in pH value (
Williams Multiple Corrosion Protection (MCP) systems offer increasing barriers against corrosion attack for confidence in permanent anchorage in all ground environments. Williams protective outer end caps may also be used to seal the nut and washer from the environment when the outer end of the anchorage will not be encased in concrete.
Typically, Williams MCP anchors are supplied in 150 KSI All-Thread Grade (as shown below) and used in various applications such as externally supported earth structures and tension tie-down systems.
Shown with 150 KSI All-Thread Bar. Drill hole diameters and bond lengths are based on geological conditions. Consult your geotechnical engineer for recommendations. Per PTI, the minimum grout cover over the tendon bond length shall be 1/2” (13 mm).
