is it? lolll
ok well, IF one were to install an interior drainage system instead of exterior waterproofing then water would continue to enter and pass through the deteriorated blocks - not helping the blocks, the wall and had one installed an INT system here then they would not have removed any clay soil n tree roots off the wall - not helping the blocks n wall.
just leave the cracks open? Those who install INT systems do not dig, excavate the exterior of wall n so they do not waterproof/repair any of these exterior cracks n so water will conitinue to enter
how about this block basement wall - so just install an INT drainage system? lol
