kgzskier2 Posted April 16, 2019 Share Posted April 16, 2019 Has anyone tried using HDPE sheets on top of plywood as a jump surface instead of plywood or fiberglass? I'm curious to know if it would need waxing at all, or if it holds up well... Link to comment Share on other sites More sharing options...
Baller MattP Posted April 17, 2019 Baller Share Posted April 17, 2019 @mmosley899 any thoughts on this? Personally I think HDPE would gouge to easily but it would depend on the durometer of the material you use. Link to comment Share on other sites More sharing options...
Baller mmosley899 Posted April 17, 2019 Baller Share Posted April 17, 2019 Hdpe does not hold up well in the sun, UV makes it brittle over time. I too think it would gouge easily. You can buy FRP(fiberglass reinforced plastic) in rolls(60'x8.5'), it can be glued to a PT plywood base, and that material works.

Baller oldjeep Posted April 17, 2019 Baller Share Posted April 17, 2019 Gouge? We use HDPE as a skidplate cover on jeeps. What in the world are you going to gouge it with? Edit - they are UHMW Link to comment Share on other sites More sharing options...
Baller slow Posted April 18, 2019 Baller Share Posted April 18, 2019 If hdpe has enough graphite colorant in it, it doesn’t degrade at all becouse light can’t penetrate it. Used to sell hdpe corrigated pipe. Link to comment Share on other sites More sharing options...
Baller theboardingschool Posted April 18, 2019 Baller Share Posted April 18, 2019 I think Beaman even makes one like that. It's more for a traveling show she ramp I think. We have been using HDPE for years on wakeboard rails, and as long as you buy the expensive stuff it will last you forever. Not sure what the difference of feel would be, but it would definitely hold up. I have a rail that is close to 15 years old in direct Florida sun, and it's totally fine.

Baller mjump Posted April 19, 2019 Baller Share Posted April 19, 2019 It works well for show ski jumpers due to its slick surface. Not so well for long distance. I just removed it from a jump.I bought and replaced it with a fiberglass surface and wax. Link to comment Share on other sites More sharing options...
kgzskier2 Posted April 22, 2019 Author Share Posted April 22, 2019 Thanks everyone for your comments. @mmosley899 I will look into the FRP Rolls, any idea what thickness you would need? I'm not finding much online. @theboardingschool Where do you guys source your HDPE from? I was looking at maybe an online order from curbellplastics and Also, wondering what thickness you use?

Baller mmosley899 Posted April 23, 2019 Baller Share Posted April 23, 2019 @kgzskier2 we used 1/8” or 3/16”. Great Dane truck trailer company uses the material in rolls to make trailers.
