Do you blow out your hole, or don't blow it out when Installing concrete anchors? For me it usually depends. As long as we drill out deep enough, as soon as you insert your anchor bolt, the bottom will fill up regardless. Here we are installing some porch post brackets on concrete piers using Tapcon anchors. They hold really well, and with this Makita impact wrench, we can use a built in setting to avoid over tightening. Check out my building plans that showcase all of our building methods and details so you can try it yourself, or have your local build have a go.
