My personal thanks to everyone who responded to this report. After reviewing your replies and discussing with our local geotechnical/structural engineer, we have decided to cut the control joints every 25'. That will control the cracking locations.
We have an existing concrete retaining wall ~153' long and 6-9' high. There are no expansion joints in the wall.
Has anyone ever sawn expansion joints into the wall to provide for expansion?
If so, how did that work?
Thank you in advance.
Thanks to everyone for your responses. We moved the building around, added walls and were able to stay at 5% max slope. It's what I knew needed to be done. I appreciate the advice.
I have a challenging site fitting a new building & parking between two existing buildings. The best grade I can get on my parking lot grades is 6.5% to 6.9%. I normally use 5.0% as maximum grade in parking lots.
Anyone constructed ~6.9% slopes. How do they work now?
Thank you in advance for...
