Hi,
We've recently finished building an astroturf track...we have a blog that documents our efforts
***HERE***. Main club website
***HERE***, and our Youtube channel also has more videos, pics and footage of things now we're completely finished and running the club every fortnight!
Main things for surface under the astro is drainage and smoothness...and making sure it's as free of organic life that WILL find a way through the astro once it's laid!
Our site was mostly gravel/dirt/mud already, we made sure we'd removed as much plant life as possible, and smoothed, raked and graded the gravel/course aggregate as much as possible before the astro was laid. Astro is painfully heavy, and you won't want to move it once you've laid it, so make sure you get things right before you do!
The sand in the astro helps keep the astro down, as it's very light without the sand fill, however, it does come out once the cars are running on it..and will always do that. Our astro was second hand, and was sand filled, and we still spend a good period of time around each meeting brushing and removing the loose stuff...in the hope that eventually most of it will have come out!
Planning is the key...good well considered track design is vital...the amount of effort needed means you should try to get it as close to what you want first time! Tricky, but possible. Think flowing shapes, nothing flat and boring...your area looks very flat to me, the challenge there will be to get some shape and height change into it!
We went for making a shaped space with rounded rolling shapes that can have the track markings laid at any position for an infinite amount of track designs...and we're loving the variety it's providing us now....every meeting the track is different...a few pics of tracks we've laid
***HERE***
Anyway...GOOD LUCK!!! Much hard work ahead
