Slappy kerb owners, I need your input:
We have a 2-part (so maybe 3m long in total) kerb (by crazyroadwalls) and the new floor of the indoor is tarmac. The kerbs are slipping around a little.
Anyone have any advice on what we could stick to the bottom of the kerbs to stop them moving? We don’t want to fix them into the floor permanently. And bear in mind when we skate there it can get to like -10c so soft rubber actually becomes hard rubber.
Any help or proven suggestions appreciated!
We’ve always used Gripfill.
I’ve used old inner soles before with some degree of success on tarmac, but - in my experience at least - freestanding kerbs’ll move about a bit if they’re not anchored in.
I have wondered about using that very thin yoga mat/exercise mat type stuff, but never tried that.
Is that permanent though? We want to be able to drag them around
Yeah was thinking that, or slightly thicker kids play mat. Or rubber car mats
Ah ok I see what you’re saying…it’s not permanent because it’s easily removable but it locks them in place and they can’t be moved.
I guess the only substitute for that is making the curbs just heavy enough to be movable without moving when you skate them. The long curb at Kurbenhagen is like that, it’s on tarmac and you can shift it but it doesn’t move if you slappy it.
Only other thing I can think of that worked for me in the past is foam. I actually cut up an old mouse mat to get mine but you can buy sheets of traction pad foam too.
Maybe some holes drilled in the floor with small steel pegs at the ends and sides (looking at the pictures on the link they seem to have notches for something like that maybe)? So it wouldn’t be fixed in place but you would need to make more holes in the floor if you wanted it somewhere else.
Apparently it really works to grind really scary handrails
Some old inner tube glued to the bottom would probably provide enough grip to stop it sliding around… maybe 
AI tells me to use Neoprene (aka Chloroprene/Polychloroprene/CR Sheeting/CR Rubber), 5mm thick with 60-70 Shore A rating.
Silicone tear strength is too low.
Polyurethane is too slick and tends to slide rather than grip.
EPDM is harder to glue.
Yoga mat: cellular foam and likely to compress and be useless with the 80kg+ weight.
Same with Plastazote (although this has also been recommended!)
