Epoxy concrete anchors are an excellent alternate to Williams high capacity mechanical anchors when applications require close anchor spacing and small edge distances. Mechanical anchors require greater spacings and edge distances because of the lateral pressure placed on the drill hole due to anchor expansion. This expansion pressure is reduced with epoxy anchor systems. Wil-Bond epoxy is ideal for passive dowels or anchors without a prestress load, however when high capacity anchors are to be prestressed the designer should consider Williams Spin-Lock mechanical anchors. Use Williams Wil-Bond epoxy anchors for concrete anchors loaded in shear. |

ICBO ES Evaluation Report #4996
State DOT's
Wil-Bond 200 meets the new ICBO AC58 Acceptance Criteria for Adhesive Anchors in Concrete and Masonry Elements. This testing criteria was developed at the request of ICBO and engineers throughout the United States in order to evaluate the long term performance and durability of various epoxy systems under real world conditions.

AC58 Test Criteria - The International Conference of Building Officials (ICBO) developed this adhesive test criteria because they recognized the necessity for engineers and contractors to be able to distinguish between poor, medium and high quality adhesives. The long term durability of the adhesive, in a variety of service conditions, is of particular importance. We are proud to say Wil-Bond demonstrates superiority and easily passes all of the service condition tests. The following data substantiates Wil-Bond’s exceptional performance.
In-Service Temperature - Test shows the strength of the anchoring systems in elevated temperatures. The following charts show the strength of Wil-Bond 100 & 200 load values versus temperature.

Creep - This test simulates epoxy performance for 30 to 50 years of service life. Wil-Bond 100 passed this test with a 10,500 lbs. tensile load on a 1/2” diameter anchor.
Dampness - This test shows the hole may be damp during installation. Therefore, if the construction site is exposed to a damp environment, Wil-Bond can be used without compromising the strength (rain, rivers, lakes, water treatment plants, ect.).
Seismic - This test shows the anchor system can withstand seismic activity, wind loading, and cyclic loading. Both Wil-Bond products passed this test with a 10,000 lbs. tensile load on a 1/2” diameter anchor.
Freezing & Thawing - This test shows the anchor can withstand freezing and thawing climates. This is very important in environments that experience an annual winter that goes below freezing.

Williams All-Thread-Bars are used with the Wil-Bond adhesive for unmatched anchoring versatility and capacities. The Wil-Bond adhesive provides a molecular bond to the substrate while coating and protecting the embedded dowel. The epoxy distributes the transmitted load from the dowel into the concrete over the entire surface of the anchor hole. Since the epoxy is stronger than the concrete, the ultimate anchor load will be limited only by the concrete or capacity of the steel. Bars can be ordered cut to length or in stock lengths up to 50 feet for job-site cutting. The 360° thread provides unmatched epoxy to bar bond and also allows installers to torque-tension the anchorage if desired. Williams also supplies hex nuts, plates and washers. Working loads should be based on a 4:1 safety factor from bar ultimate strength. Listed anchor embedment depth based on 3000 PSI concrete. Assume approximately 15% waste of epoxy. |
