Best Sub Floor for Putting Turf

[Brettster]

hotshot22 -

Atop that i will have 1/2" eva mats and then 7/16 osb wood followed by turf. Although i am considering switching that order and having the wood, then eva mats, then turf atop that. Ill be doing 4x8ft boards of the leveled underlayment, osb, and gym mats adhered together for ease of moving, then rolling the turf over.

I used 1/2" OSB with these 1/2" thick puzzle piece (gym mats) on top:

I worry that gym mat directly under turf is too squishy. Could always have wood under turf in stance section though instead of gym mat. Will be cutting out section for holygrail strip. Sounds like gym mat or wood underneath will not impact stimp speed.

It's not too squishy - it's just right actually. Notice when you walk on grass outside that it's squishy and you want to have that feeling in your simulator. You don't want it to feel hard underneath like you're walking on hard flooring.

Here's a link to a post on my Sim Shed Build where I laid my turf in my Shed:

I put the turf in first, and here's a link to where I was pulling up gym mats/turf to cut a hole for my hitting mat:

I can tell you, this part was pretty difficult. You want to use a good cutting knife (like a Fatso from Home Depot), and some Grass Seaming Tape (to match up turf) like this:

You also will need some double sided gel-like carpet tape that you can pick up at Home Depot when you stick it down for the final placement.

Let me know if you have any questions,

Take a look at Pro Putt Systems if you haven't already. They offer an interlocking plastic base system that incorporates cups - your turf lays right on top of that. The turf is also fantastic - I got a 15'x22' bulk piece with no seems and it has held up amazingly for the past two years.

How much did the Bulk Piece run you? Was shipping included, or did you pick up at a location? That would be the best way to do it.

What is the website for Pro Putt Systems, is this where you bought:

Yes on the website. I compared a lot of different turfs and I wasn't really trying to do a budget build. Their turf is a heavier, more robust material per square foot, and you pay for that. I believe my piece was around $1700, and I had it shipped. Yes, it's expensive, but I live by the belief that it's cheaper to do it right the first time. You can plug in your desired dimensions and they will show you the price. The plastic base is also really well engineered - it takes a bit of planning to figure out where you want to put the cups, and whether or not you want to use edge pieces with borders on them. I actually enjoyed the planning part and once I began installing the base I made some changes as I went, but it was fun and it turned out great. The turf lays down right on top of the base and requires no glue or staples to hold it down as it is heavy enough to stay in place. But, once you cut the holes for the cups, that's it! I actually laid out ball markers on the turf for weeks where I thought I wanted the cups and moved them around a bit before positioning the cups and cutting the holes. The base design allows you to rotate the pieces with cups in them to get it very close to the location you want, and then the cups themselves offer small adjustments - kind of hard to explain, but once you see it you understand. I've added a few pics of my progress.

M3Wrath - Wow that looks great! Impressive. That is a lot more expensive - my piece of 15'x10' cost around $700. Of course it does not have any of the plastic/base subfloor pieces like that and I had to build my own subfloor with 4x8 sheets of ply and 16' 2x4's for support on top of concrete.

Really nice looking with the holes cut in. How do you cut the holes in their turf/base? Do they sell you a hole cutter or expect you to purchase your own? What is going on with those circles around the holes, is that something you chalked out to get an idea of a 6' putt?

Thanks for pics,

No need to cut holes in their base - they have regular (non cup) pieces, and then you order a few "with cup" pieces and just plug the cups into them. It's a well designed system, but yes, expensive. Once I had the carpet in and the cups placed where I wanted them, I cut the carpet to expose the cups. I made a few chalk circles to mark a 3' circle around one, and a 5' circle around another. If you want to get rid of the circles you just need a wet washcloth to wipe off the chalk.

[Brettster]

Excellent idea M3Wrath - using chalk circles 3' and 5' around cups is a great way to build on the visual and setup for distances when practicing. How often have you noticed you're wiping these away, or they get wiped away by footsteps?

Look at Camry.com. I did not use the carpet, but I did build up putting and hitting surface based on there diy videos.

Using “nylon putting extreme” from turf factory direct.

Curious what you ended up doing in terms of carpet on the wood or the foam mats?

I turfed my entire sim basement. Laid Southwest greens putting turf directly on concrete, they used a glue. I have regulation holes in the concrete, they used a diamond drill to cut the holes, made a hell of a mess! But I have regulation holes.
