RE: Handicap Wood Ramp Detail

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Could you bury the stringers in the ground (using treated wood) and run the
decking down to ground level? 

A support member, similar to a step tread, could be framed just below the
deck to distribute the load to the ground surface?
