Drain Pipe in Retaining Wall – Why Needed....
Why are drain pipes essential in retaining walls?
They help release water pressure that builds up behind the wall during rain or groundwater movement.
Without drainage, hydrostatic pressure can cause cracks or complete wall failure.
✅ Use PVC drain pipes or weep holes
✅ Add gravel + geotextile for proper filtration
✅ Place drains at the bottom rear with slope

Drainage = Strength + Safety
