Hi all. I live in the North Shore Massachusetts area. My property has a cinder fill block retaining wall probably over 130 feet long with heights sloping from 1 ft up to 6 feet high on the other end. This wall was built back in the 1950's and it is the original wall. Due to having no proper drainage system, the wall is beginning to crack due to freezing and thawing over the winter time. I know this is caused by lack of proper draining system. Can anyone recommend what I would need to do to make a proper drainage system for this wall? I am a DIY and one day the wall will need to be replaced. Landscapers have quoted over $50k to remove and install a new wall system and the stairwell that is attached to it will also have to be replaced. It will take us a long time to come up with the funds but we would like to install a proper drainage system for the time being while we are saving for this future project and to avoid an early wall failure while we are saving. Any ideas on drainage greatly appreciated and thanks in advance. BTW, I saw something on TV about digging a hole every 4 to 8 feet with a fence post digger and dropping in PVC pipes (with holes ?) in the hole and stub the other end of the pipe out of the wall. May require drilling weep holes in front of the wall. Also backfilling the post hole with stones. I could not seem to find any information on such drainage system and what size pipe is needed for each post holes as well as what goes on top of the pipe when it stubs out of the ground. Thanks again.
