The SP18-716 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 7/16" thread accommodating up to 2" thread. Supplied with 1" washer and 7/16" x 1" hex-head bolt. REQUIRES 1 BAG OF EPX2 GROUT PER ANCHOR.
