How Many Blocks for a Retaining Wall?
Calculate retaining wall blocks, cap stones, base gravel, and drainage materials by wall length and height.
भारत में
Stone masonry: ₹200-400/sq ft। RCC: ₹300-600/sq ft। Gabion: ₹150-300/sq ft। 1 meter+ height: structural engineer MANDATORY। Hilly areas (Himachal, Uttarakhand, Northeast): retaining walls critical for landslide prevention।
Drainage
Weep holes every 1.5-2 m। Gravel backfill behind wall। Without drainage = wall failure guaranteed in Indian monsoon।
⚡ CalcWolf Insight
Interlocking retaining wall blocks have a built-in setback (lip) that angles each course slightly toward the slope. This "batter" (typically 1 inch per course) counteracts the soil pressure pushing outward. Never stack blocks vertically without setback — the wall will eventually topple forward.
