Wheelchair Ramp

I want to build a ramp with a friend, so she can enter and exit a power wheelchair. Can someone tell me the right combination for concrete

they sell the stuff already mixed, just add water

Is there a ramp or a ramp just great, the wood may be more appropriate if it is a long-term

I bet you thought you could do that easily, lol, here are the ADA requirements overwhelming

Do not know the composition, but deal with the requirements for ADA ramps. They speak of the slope and protection devices, among other things ..

instead of worrying about how much sand and how much portland cement why not buy bags of ready mix concrete, where all you have to do is add water - should be available in your local or Lowes Home Depot

Lowe's or Home Depot can advise you step by step of your project! Good luck!

good combination for a ramp would be 4 parts ballast to 1 part cement
