Introduction: DIY Pitching Mound

My son has outgrown his pitching mound so I decided to build another one. He's just starting his Freshman year so I know he will still be growing and we will get at least another 4 years out of this one. The mound has to be sturdy and weatherproof. Mobility is not an issue as we will not be moving this one around. I

Step 1: Base

I decided to use a piece of 4' x 8' treated plywood as the main part of the mound. For the base, I started with 4 1" x 10" x 10' pine boards. The upper part of the mound - I'll call it the upper base - is 20" deep and 4' wide. Subsequently, I made a mark at 20" on the pine board and drew a line to the end, stopping at 2". See photo.

Step 2: Bracing

I used a lot of scrap pieces to brace the 1" x 10"'s - probably overkill but I wanted to make sure nothing moves.

Step 3: Top Sheet

I added the 4' x 8' sheet of treated plywood, securing with drywall screws. Make sure your base is exactly square prior to securing the plywood. I soaked all pine boards with Thompson's water seal prior to securing the plywood.

Step 4: Add Turf

I had a large piece of high-quality turf that I decided to use for the covering. I used carpet adhesive and staples to secure. I was about 12" short so I bought a piece from Menards. To finish, I added an old pitching rubber. The mound is solid with any pitching movement.

    Question 5 months ago

    Hopefully you are still taking questions... Can you confirm that these are the correct dimensions? Total length = 10' (96") made up of 20" flat top + 84" descending angle, Width = 4' Mound Height = 10" dropping down to 2"

    I’m a little lost. 10’ is equal to 120” not 96”

    Thank you for the info! I like how you have gone back and answered everyones questions. I have a workshop and want to build a mound for my son's little league. Was thinking about trying to build a fiberglass mound similar to this https://portablepitchingmounds.com/product/pitch-pro-486/ . Have you had any experience building a fiberglass mound?

    Probably less than $50. I'm going to sell it soon and probably ask that amount.

    Hi there! Great post! I was curious, how did you fasten down the rubber? I usually see the mounds come with spikes to stick in the ground. is there did you use some sort of glue or screws? Thanks!
