Based on ICBO official testing and approved by City of Los Angeles and Los
Angeles County - Hilti HY-150 Epoxy Anchors using  1 inch diameter threaded
rod and HY-150 resin are good for an allowable  5700 pounds of tension each;
if embedded 8  inches in the concrete. Look in the yellow pages under
concrete or building materials suppliers for a Hilti Dealer near you.

	Subject:	[TowerTalk] Cement Drilling and Bolt affixing


	Hello all,

	I am in need of drilling two holes, about 1.5 or so inches in my
tower
	cement pad to add a restraint to my tower base.  I will probably use
1"
	bolts about 12" long.  Will need about 4" of bolt above the cement
pad.

	My situation,  after drilling the hole for the bolt, I understand
that there
	is a compound I can use to "glue" the bolt into the hole.  I have
never done
	this where there would be vertical pull on a bolt, only pressure
broadside
	to it.

	What recommendations might y'all have out there.

	By the way, this "bracket" is to take a small flex out of the tower
base and
	will remain on a permanent basis.  Only removed if the tower needs
to be
	tilted over.

	Thanks for your assistance in advance.

	Mark, WT6P
