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 ½ 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
Sacramento, CA
