Installing shed tie downs can be necessary in order to pass the building code requirements. In some parts of the United States, and particularly in areas which are prone to high winds, sheds are vulnerable to loosening, even if they have foundations, and may cause damage. The power of hurricanes and twisters is enough to lift even a heavy woodshed, fixed in concrete, away from the ground. For this reason, many states require you to fix a shed into the ground using tie-downs.
Step 1 - Preparation
Before you begin to tie down your shed, ensure that you have put on safety gloves to protect your hands. You may also consider using safety glasses if you are worried about wood pieces flying into your face. Your kit should be of the anchor and tie variety. Remove the pieces of the kit from the bag, and make sure that all the pieces are matched well. The kit should ideally contain two anchors, a cable, and metal clamps to hold the two pieces together. In order to secure your shed, you will need two kits.
Step 2 - Installing the Anchors
The first install the anchors. You will need to dampen the ground with a hose slightly, before pushing the anchor into the ground. You may need to loosen the soil with a spade if your soil is particularly hard to penetrate. When installing, twist the anchor slightly, so that it is under the bottom edge of the shed. This will help you when you are cutting your grass. Once the anchor is in, you will need to place the auger portion of the anchor in the ground, leaving only 2 inches or so of stem. Attach one end of your cable to the anchor.
Step 3 - Installing the Cable
The cable can be used to attach the shed in a variety of ways. If you have a loose-beam shed, you can slide the cable around the beam, and then bring the cable back to the original anchor. Sheds that have skid-mounts can have the cable pushed between the deck and the skids and then pulled around to the opposite corner. For sheds that are not accessible in this way, an alternative is to pull the wire over the shed roof and attach it to an anchor on the opposite side. Both ends will need to be tethered in this fashion. These are not the only methods of tie-down, but any more complicated instructions should be available on the shed tie down pack.
Step 4 - Using the Clamp
Take your wrench and first loosen the clamp so that the cable can be inserted into it. Then tighten again, so that one side of the cable is secured to the clamp. Pull the loose cable through the anchor, and secure it by tying a knot before cutting it down to a suitable size. You will probably need to saw through the wire in order to trim the cable.
Once you have repeated this action on all of your corners, ensure that the anchors are securely in the ground by hammering them lightly, and make sure that your cable is tight at all ends. Once this is done, your shed should pass the building regulations of your state.
