• 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.

• 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 epoxy anchors for concrete anchors loaded in shear.

Applications
  • Concrete Foundation Repair
  • Seismic Retro-Fit
  • Machinery Anchoring
  • Anchors for Rail Systems
  • Underwater Doweling
  • Concrete Dock Repair and Construction
  • Anchors Subject to Large Shear Loads
  • Bridge Pier Reinforcement
  • Pier Cap Repairs
  • Dam Refacement
  • General Plant Maintenance
  • Column Anchors
  • Light Poles
Ultraond Epoxy Concrete Anchor System

Approvals and Listings
ICC (formerly ICBO) ER Evaluation Report #4996
State DOT’s
Ultrabond products meet the new ICC AC58 Acceptance Criteria for Adhesive Anchors in Concrete and Masonry Elements. This testing criteria was developed at the request of ICC and engineers throughout the United States in order to evaluate the long term performance and durability of various epoxy systems under real world conditions.
Ultrabond Technical Information
Shelf Life: 28 Months
Storage: Room Temperature out of direct sunlight
Application Temperature Range: 35° - 115° F
Color: Resin - White
Hardener - Black
Mixed - Concrete Grey
Viscosity: Resin - 330,000 cps
Hardener - 150,000 cps
The Ultrabond Epoxy Anchor System is a two component 100% solids, high aspect ceramic blend amine-based epoxy. It is a solvent free, high strength, high modulus, moisture insensitive, non-sag epoxy system.
*Temperature application range or product information range refers to the temperature range that the product is recommended for use.
The product will need to be warmed prior to use at temperatures below 70° F.
AC58 Test Criteria - The International Code Council (ICC) 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 Ultrabond demonstrates superiority and easily passes all of the service condition tests. The following data substantiates Ultra-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 Ultrabond 1 & 2 load values versus temperature.

Ultrabond 1 In-Service Temperature

Ultrabond 2 In-Service Temperature

Creep - This test simulates epoxy performance for 30 to 50 years of service life. Ultrabond 1 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, Ultrabond 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 Ultra-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.

Bar Strength Charts
Williams All-Thread-Bars are used with the Ultrabond adhesive for unmatched anchoring versatility and capacities. The Ultrabond 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. Williams offers hex nuts, plates and washers with each anchor bar. Working loads should be based on a 4:1 safety factor from bar ultimate strength. Listed anchor embedment depth based on 3,000 PSI concrete. Williams recommends epoxy dowels to only be specified as passive (non-prestressed) anchors. Williams bars should never be torch cut.
