MATERIAL SPECIFICATION OF HIGH PRESSURE TEMPERATURE BOLTING
See Table 1 for material test data. Each Sleeve is approximately twice the bolt diameter with a depth of 8 bolt diameters, minimum Tests by a state Department of Transportation laboratory indicates that the Wilson Anchor Bolt Sleeve provided greater pullout strength than the regular grout pocket. The grout pocket was formed in a concrete mass and the sleeve of the same size was cast into the mass. After curing the concrete, #5 reinforcing bars were set in each pocket, using expanding grout. When cured, both bars were given a tensile load. The standard pocket failed when the bar with the grout attached pulled out. The Wilson Anchor Bolt Sleeve retained the grout and failure occurred around the bar. The sleeve remained intact. When used as a sleeve for anchor bolts the product is in an in-place form and not considered a structural member. Due to its configuration 180 psi is the maximum compressive loading.

NOTE: Grout Estimate based on .87 cu. ft. yield per 100 lb. of non-corrosive grout.
Composition and Materials:
The Wilson Anchor Bolt Sleeve is manufactured of high impact plastic. It is non-rusting, non-conductive and lightweight. Single unit construction provides for reduction in installation labor because no welding, threading or cleaning is required. The configuration is such that the grout and concrete "lock" it in place, providing greater pullout strength than with straight pipes.
