Hardscape & GradingCâu 63 / 100
A dry-stack (mortarless) segmental block wall relies on what for stability?
a.Mortar between every block
b.A concrete cap only
c.Block interlock, setback batter, gravel backfill, and often geogrid
d.Steel beams only
Giải thích
Mortarless segmental walls gain stability from the interlocking block design, a slight backward lean (batter or setback), free-draining gravel backfill, and geogrid reinforcement layers in taller walls. There is no mortar, so drainage and reinforcement carry the loads. Proper base preparation is also critical.
