Simpson Strongtie AT-XP10 Adhesive Anchoring System
Adhesive anchoring or chemical anchoring has been around for some time. It offers some of the highest strength anchoring available in concrete. It used to be a little tricky to use but products like the Simpson Strongtie AT-XP10 makes it much easier. The AT-XP10 can be used in any good quality 10-ounce caulk tool. The better install tool is the CDT10S that Simpson offers. It has a better ratio and is well built. If you are just going to do a couple installs a good quality caulk gun will work just fine. While the tube looks like a single tube, it is a two-part formula, there is an inner tube that contains the hardener.
Installation is simple. Drill your hole and prepare by blowing the hole, brushing the hole, and then blowing one more time. Just remember blow, brush, blow. Your goal is to knock off the dust and loose particles of the side wall of the hole. Now install the nozzle on the cartridge of AT-XP10. Dispense some of the material until you can see one consistent color. Fill the hole to about 2/3 or so and twist the rod in. You goal is to have the chemical just oozing out of the hole. Once the adhesive fully sets you are good to go. The product comes with one nozzle, which will do the entire tube: IF YOU DON’T STOP! Depending on the temperature, you will have about 4-5 minutes or less before the chemical starts hardening in the nozzle. So, obviously the trick is to get all your holes laid out cleaned and ready to roll before you start.
The video below gives you a nice overview of the product and installation. We have a customer that uses chemical anchoring and routinely uses a 5/8”-11 x 8” 304 stainless steel cut stud in his application. So, we started stocking them for him and now have them on our website if that size fits the bill.
