As we don’t have too much space behind lower container we decided to put the drain in front of clay retaining wall rather than ‘classic’ drain behind the wall. So when Cosmin was chipping concrete I started digging the trench….
we got metal pea and punched drainage pipe…
when the trench had correct slope we put geotextile under container space to separate clay from metal pea to have nice and clean space under containers
cutting holes in geotextile for piles
we created nice walkable, clean space
to provide double layer of clay protection we put punched drainage pipe into a sleeve
now is the time for metal pea cover
wrapping geotextile around the draiage and pinning it down
after many wheelbarrows of metal pea, we have tidy and hopefully drained space for our lower container
