This will improve the stability of the wall and the gaps between the stones will allow water to seep through reducing hydrostatic pressure on the wall. If using mortar, a reinforced foundation may be required to prevent cracking also consider the colour of the mortar. A mortar using only cement and sand may look too dark. Try building a test wall using a lime/cement/sand mixture, for example try 2 parts lime, 1 part cement and 9 parts sand. Thanks for the advice - would you still put in agi pipe drainage or rely on allowing the water to seep through? Also, if doing a dry wall without mortar as you suggested what sort of base would you use? Re: Stone retaining wall - advice needed 4Nov 14, 2016 8:18 pm Hi, just bumping this thread again. I have decided to go with a dry stack wall as I have found enough large rocks to do the job.
