NOTE: supports the coping once concrete is poured and attached to it with bolts

• 2x4 Support PostNOTE: Support the coping and the formwork for the concrete wall.• 4000 psi ConcreteNOTE: There are not standard expansion joints used but a controlled

hair line cracking. There are also steel expansion joints that remain with in the concrete creating a thin expansion joint.

• Drainage BoxNOTE: This types is used with there is a below grade drainage. These

are boxes made from plywood and will have to be cleaned out from time to time. There is also another method for below grade and that is using a 4” PVC pipe that is on a downward pitch of 1/4” per foot.

Surface materialsMaterial Pros Cons Cost Lifespan

Concrete -Durability, long life 30+ years -Organic Shapes, curves and bowls flow better in concrete. -Surface / Structure repairs should be minimal

-More difficult to work with -Longer build time -Expensive -Generally the most expensive surface

-Most expensive 50+ years indoor/outdoor

Skatelite© Buy Some

-Specially designed skate, BMX and inline surface -Good for BMX parks -Withstands weather better than plywood, masonite -Cheaper than concrete -Exceptionally long lifetime indoors

-Expensive -Some or all surface needs replacement in 4-6 years

-More expensive than plywood less than concrete

4+ years *outdoor heavy use 6+ years indoor heavy use

Metal -Exceptional lifespan, no surface replacement needed -Good for BMX parks -Will withstand the elements; snow, rain, ice, fog, etc...

-Absorbs heat, Gets very hot -Non porous, gets very slick with little moisture -More difficult to work with than wood, requires more labor cost to install

-Less expensive than poly- carbonate skate surfaces -More expensive than plywood

20+ years indoor/outdoor

Birch Plywood

-Smooth skateboard/inline surface -not recommended for BMX -Does not last outdoors

-Less expensive than all of the above surfaces

5+ years indoor heavy use 1+ year *outdoor

Masonite -Smooth skateboard/inline surface -not recommended for BMX -Does not last outdoors

-Less expensive than all of the above surfaces

3+ years indoor use 1+ years *outdoor heave use

Plywood -Cheap -Does not last long indoor/outdoor -Will detiorate fast

-Cheap 2+ years indoor use 1+ years *outdoor
