Stack Remaining Courses and Backfill with Rock
At 3:33 in
We hit a Buried Line -on the Last job of the season.
What happens here
After the first course, additional layers of retaining wall blocks were stacked, with geogrid layers placed at regular intervals to reinforce the structure. The area behind the wall was generously backfilled with clean rock. This substantial rock backfill acts as 'cheap insurance' against hydrostatic pressure, allowing water to drain freely through the porous wall system and preventing issues like the 'hydrostatic blowout' that can damage walls.
Goal: Subsequent courses of retaining wall blocks were stacked, interspersed with layers of geogrid, and extensively backfilled with clean rock to ensure superior drainage and prevent hydrostatic pressure buildup.
