CorrosionProteotion

Resin anchoring provides quick rock reinforcement for active and passive installations fordams, locks, underground structures, rock cuts, and tie downs. Both Williams Grade 75 and150 KSI All-Thread Bars are used for resin anchoring.Williams inventories quality resin cartridges. Resin cartridges consist of two components: (1A polyester resin grout and (2) its catalyst. These precisely measured quantities areseparated by a thin plastic film and are enclosed by this same film. After holes are drilled,the sausage-shaped cartridges are inserted. When rotating a deformed bar through thecartridge and into the hole, the components are mixed and the curing action begins. Whencured, the comprehensive strength of the resin is often stronger than the surrounding rock.Resin systems offer a quick economical approach resulting in an encapsulated rock anchor.

Tensioned Bolts vs. Non-Tensioned BoltsTensioned bolt systems use fast-setting resin for anchorage in the back (bond zone) portionof the drill hole. The forward portion of the hole can be left open for temporary boltingsituations, filled with slow-setting resin or pumped with cement grout depending on thesituation. Non-tensioned systems would use resin of the same set time the full length of thedrill hole.

- - Drill Hole DiameterThis chart shows the length of drill hole that wi ll be encapsulated by a twelve inch polyester resin cartr idge. I t should beused as a guide to the most oommon combinations of hole diameter, bolt diameter, and resin diameter. Othercombinations are possible provided the annular space does not exceed 1/4" to 3/8".Due 10 the difficulty of overcoming the drag of the bar through the resin cartridges during insertion. ful ly encapsulated resltdrill holes are most practical With shorter anchorages.

Bars Associated with Resin AnchorsFor bar selection, WILUAMS offers three continuously threaded bars, the R71, R61 and the878, and a standard high strength threaded reinforcing bar. the R6J.Working loads whenused as a rock anchor should not exceed 60% of the ultimate strength shown, as a flnalfockoff load.
