When you wish to add concrete screw anchors to your foundation before you finish the foundations, then this is a simple matter. Concrete screw anchors help to support the foundations, and any buildings on top of them, preventing cracking and subsidence which can ruin your projects. In order to fit the concrete screw anchors into the ground, you will need to know how and when you can fit the anchors, and how many you will need to install in order to get the right amount of protection for your building. This can be easily done if you have some home improvement tools, a few screw anchors, and a little bit of time in which to manage this installation.

Step 1 - Preparing the Foundation

Once you have the shims in place for your concrete, you will need to start marking out the area where the anchors need to go. Use your tape measure along the side of the concrete, and use the tape to mark along the string where each of the joints will go. You may prefer to tap the anchors into place before you add the concrete, but you can also do it after the concrete has been poured.

Step 2 - Installing the Concrete Screw Anchors

Take your drill, and drill a suitable hole into the concrete before it is fully set. Push the concrete screw along the edge of the bit, so that the hole does not close over before you have added the screw. You can use a hammer to drive the anchor straight into the concrete, and then put a bolt and washer into the hole in the concrete. Tighten the bolt and washer until the concrete is completely secured, and then leave the concrete to set completely. Once this is done, you can proceed with the rest of the foundations.

Step 3 - Removing the Concrete Screw Anchors

If you have decided that you don't want the anchors in the concrete any more, or you have noticed that the anchors are in the wrong place, then you will need to remove them. This is a bit more difficult than adding them, and you will do damage to the concrete which cannot be avoided. Take your wrench, and pull the bolt of the screw so that it starts to loosen. You may have to completely unscrew it, but you might also be able to pull out the entire screw before the bolt is loosened. Remove the screw from the concrete.

Step 4 - Repairing the Concrete

After the screw anchor has been removed, you will need to repair the concrete. Mix up a little more concrete, and set it into the holes. Leave this to dry overnight, and then use a sander to smooth down the edges of the repair until it resembles the rest of the concrete foundation. You can then proceed with the rest of the build.
