Hi guys i'd like to ask for your help on this one. After 3 years of struggling finally managed to convince the mayor in my hometown to remake our skatepark and pour some concrete over the wooden obstacles(only thing made of concrete is the bowl) . In fact we are gonna use the wooden obstacles as mold for the new concrete ones. This is vital as the park is outdoor and you understand what happened to wood after some years.

More specifically we are gonna take advantage of this and ask them for some new obstacles too and one of them is gonna be a small bank that u can grind on it(Sort of those we see in videos in barcelona). Well the reason i am posting this is because i dont have a clue about the height of this thing or the angle of the bank or the coping on top as i havent skated something like this. I wanna have something easily skateable but NOT too easy just something fun and suitable for a skatepark. So in the next days  i have to make the designs and any help would be appreciated.

Note: I am from greece and we have only one concrete park made by skaters who had a day job as construction workers, so there is no expertise. The way we are gonna do it is in cooperation with municipal architects and civil engineers.

this is a bad idea. unless you're saying that you're tearing the old stuff down, then using the wood to build your forms. if you're thinking you're just gonna pour concrete on top of the existing structures, you're in for some trouble.

Not on top man we are planning on removing the top and pour it in then remove the rest of the wood.  Besides civil engineers should know  stuff like this.  We are not going to do it by ourselves we put the skate part they are gonna put the rest.

you're going to waste a SHITLOAD of concrete if you do that. plus, the structures most likely won't hold together with that much wet crete in them. you'll end up with a very expensive set of mounds.

and besides, why stick with whatever you had, when you can have a clean slate?

im not trying to be a dick when i say this, but find someone else to work with the city on your skatepark rebuild/redesign. that "pull the sheeting off and use the templates/skeletons as forms" idea is horrible. do you have a local skateshop or some older skaters or something? seriously. i'd be willing to bet that if you flew some american or canadian skatepark builder to greece for a few weeks, they might even head up the crew for food and lodging, just to beable to go to greece.

Didnt i mention that we will have civil engineers with us? I am sure they know stuff like this.
Yeah i know we have to fill in the structures with materials and then pour concrete. I know the structures wont hold so we are gonna reinforce them in the sides with supports. But i wont have opinion cause its the engineers' job. My job is to give them advice to make things skateable. In fact i am not sure if they are gonna this way we just told them we want the same structures on concrete.

They may not have skateboarding expertise but i trust them. In 1997 the municipal architect designed a kickass bowl by only studying thrasher and  googling information. Then civil engineers made it happen. The result was great.


Well the existing structures are fairly good and we dont want something else. Besides the space we have limits our imagination. The only problem we have is the wood that has to turn into concrete. Of course we are gonna make 2 new additions and the one is the  thing above.

As for the cost i dont care i wont pay for this its on the goverment and EU.

As for the last part no you are not sounding like a dick its the common sense, but you are not living in Greece either, a place where there is no common sense. It took us like 3 years convience them about this if we tell them about flying some canadian or american dude they will be in disbelief and they will start telling us that they can do it and they need no americans or canadians like it happened in the past, but suprisingly they did good job.

Finally we are the oldest skaters here and we are about 18-22 and the local shop isnt owned by skaters.


To make a summary.
Civil enginneers know everything about concrete, materials and constructions generally. We the skaters have to advice them on stuff like the coping, angles and generally the skate part. Everything is set except the thing above that i dont know how to do it because i havent seen something like that in my life. So i still need your help on this one.

We made the last park this way and it was good except the wooden parts i think we will work it out.

if money isn't an object, have someone from dreamland, newline, grindline, placed to ride, or other decent skatepark contractor come oversee the project.

but i guess if all you're building is a bank... whatevs.

The existing wooden structures that are gonna be  concrete are 2 big banks, a big funbox and a box.
The things that we are gonna build from scratch is the replica on the video and a manual pad with a ledge on the side for step up and grinds.
There is also a concrete bank here and the concrete bowl that will remain the same.

Also the flatground is busted so its gonna be replaced too.


I told u the cost is not a problem for the materials it is a problem if they are gonna bring someone that is not working for the town.

you need to build the structures out of rebar and not wood, if you are building a concrete quarterpipe, (another thing about rebar is that you can weld the coping onto the top of the rebar frame, which wood wood not allow you to do ) depending on the height of it you may need a cement truck with a pressurized cement sprayer.... and you will need a lot of people to smooth the cement, using concrete trowels you need two of them, and water bottles to spray water on the cement during the smoothing process.  another problem that arises is that cement dries fast.  the trowels will be needed to smooth out your cement



heres a vid of people smoothing out flat cement ......smoothing out curved cement requires a lot more work and a lot of cement
