High speed wind forces can damage your lawn and farm by shifting the make-up of your soil. Wind is inconvenient and potentially dangerous. Helicopters use wind deflectors to reduce pressure on the cockpit, and the same technology can be used to protect your soil from wind and tornadoes. By keeping your soil in place, you can save your lawn from costly soil replacement.
Dig a 3-by 6-foot hole using a shovel. Make the depth of the hole 2 feet.
Put 9.07 Kilogram of cement powder and 4 gallons of water into a cement mixer. Mix the cement mixture thoroughly.
Pour the cement mixture into the hole. Smooth it with a trowel. Let the cement mixture dry for three to four days.
Measure a 45-degree angle on two of the planks. Place a protractor level to the ground and on the end of a 2-by-4 plank. Place a ruler at a 45-degree angle from the bottom left corner to the top right of the 2-by-4 plank that will go on the left side of your deflector. Place a ruler at a 45-degree angle from the bottom right corner to the top left of the 2-by-4 plank that will go on the right side of your deflector. Mark these angles on the wood using a pencil. Use a measuring tape to help you guide these lines.
Cut the left side 2-by-4 wood plank at a 45-degree angle using a table saw. Set the angle of the blade to 45 degrees. Cut the right side 2-by-4 plank at a 45-degree angle. Place these planks flat on the right and left sides of the cement foundation.
Place seven wooden 2-by-4 planks side-by-side on the cement foundation. Place them in between the cut planks, ensuring the cut edges are flush with the planks next to them. The seven wood planks and two side planks should create a solid wood layer.
Drill four pilot holes through each wood plank and into the cement using a cement drill bit and power drill. The pilot holes should be 4 inches in depth and 2 feet apart along each plank.
Insert screws into the pilot holes. Replace the cement drill bit with a screwdriver head. Drill in a clockwise direction from the top of the wood planks into the layer below. This secures the planks to the layer below.
Build another layer using Steps 4 to 7. Use 1 less plank than in Step 5. Repeat this process until you make a triangular wooden shape, using one less plank in each level. The shape creates a wooden wind deflector.
Orient the wind deflector so the narrow end is pointing into the wind, and the wide end is towards the soil you want to protect.
Safety goggles, a mask, and work gloves should be worn when using a table saw.
