Frequently Asked Questions (FAQ)
What is the Segmental Retaining Wall Blocks & Gravel Calculator and how does it work?
Landscaping and civil geotechnical engineering tool. Determines required modular blocks and backfill drainage gravel to prevent hydrostatic pressure.
How do I use this Segmental Retaining Wall Blocks & Gravel Calculator?
Enter Retaining Wall Length (meters or feet). Enter Exposed Wall Height (meters or feet, e.g. 1.2 m). Select Modular Block Face Dimensions (e.g. 15x40 cm or 20x40 cm). View Total Blocks, Drainage Gravel (m³ and tons), and Base Leveling bags.
What mathematical formula is used in this calculation?
Wall Area = Length * (ExposedHeight + 0.15m burial). Blocks = ceil((WallArea / BlockArea) * 1.05). Drainage Gravel = Length * Height * 0.3m thickness.
