Our new outdoor shed in our backyard was sitting in a place with a little dampness and soft grass nearby. I decided to install a 4" perforated drainage pipe as well as a new pressure-treated ramp, allowing easy access to the shed while also helping to deal with our drainage issues.

Supplies

** If you also have drainage issues, I'd highly recommend the following 2 items

(1) Perforated Corrugated Expandable Flexible Landscape Drain Pipe, 4-in. by 25-ft.

(3) 2" x 4" 6ft pressure-treated lumber

(7) 1" x 6" 6ft pressure-treated lumber/decking boards

**These screws are also weatherproof and designed to handle the weight/torque of being pulled and under the pressure of the weight as you repeatedly use the ramp and apply torque to the ramp where it's secured to the shed.

Step 1: Install 4" Perferated Drain Pipe

For my installation, I dug a 1ft trench around one side and the front of my shed. I installed a 4" perforated pipe to help guide any groundwater toward the slope of my yard and away from the shed. I buried the pipe in crushed granite stone chips to help allow the water to flow freely. If you do not have drainage issues, you can skip this step. I included the images to show how this pipe can easily flex around corners and should drain to open air.

Step 2: Secure 2x4's to Your Shed

Here you can see I fastened (3) 2x4's to the base of my shed's 4x4's using the ledger screws noted above. You can have these 2x4's extend out as far as you'd like. I chose to have 1ft under the shed, with 5 feet exposed sticking out of the shed. NOTE: before installing these 2x4's, notice I cut the ends on an angle that allows the first board to be mounted on an angle, making it easier to load things like lawnmowers or snow-blowers up the ramp.

Step 3: Cut & Install Decking Boards

Cut the 1x6's to the length needed for your installation. I went flush to the far ends of each 2x4, which was 64" in my situation. (My shed is 8x10) You can see I used a fiberglass marker used for driveways in the wintertime as a spacer to distribute the boards with a small space between them evenly. You can use anything you'd like - or you can put your boards flush against each other. I prefer the look with a small gap between each board, as shown here. Keep in mind, my first board was screwed to the angle I cut on the 2x4's, allowing for a nice ramp for any wheeled equipment to access the shed easily.

Step 4: Finished

This is the finished look. Using pressure-treated lumber, the 2x4's are in direct contact with the ground. They won't last forever, but I like the look, and this only took a couple of hours to build. It shouldn't be a big deal if I ever need to repair or replace it. This was a pretty simple project that wasn't very expensive and it added a ton of functionality for us because we had a swampy grassy area in front of our shed that made it difficult to use. Now we enjoy using the shed without any issues whatsoever.
