The SP12-38 is used in conjunction with our EPX2 grout to bond with existing asphalt. Constructed from zinc plated steel, the bottom of the anchor is flared and sealed to act as a wedge when pushing the anchor into the ground. A welded spiral along the length of the anchor provides for a strong bond with the grout. The top of the anchor incorporates a large washer with internal female 3/8" thread accommodating up to 2" thread. Supplied with 1" washer and 3/8" x 1" hex-head bolt. Requires 1 bag of EPX2 grout per anchor.
