How to Build a Retaining Wall on a Slope: 10-Step Guide

Описание: Building a retaining wall on sloped terrain requires precise planning and technique. This comprehensive 10-step guide shows you exactly how to retain a steep slope using segmental wall blocks—from proper excavation depth to drainage systems that prevent failure.

In this video, we demonstrate the complete process of building a retaining wall on varying terrain using our Murata Wall blocks. You'll learn how to establish proper grade on a slope, calculate embedment depth at the lowest point, step up your excavation efficiently, and install critical drainage systems. Whether you're a DIY homeowner tackling yard erosion or a contractor perfecting your technique, this tutorial covers the essential methods that ensure your retaining wall handles slope pressure and water management for decades.

You'll learn how to:

Design and measure for proper height and material calculations
Establish grade and embedment depth on sloped terrain
Excavate efficiently using the step-up method for inclined sites
Install geo-filter fabric and drainage pipes to prevent wall failure
Set a level base course on uneven ground using reference lines
Backfill in proper lifts with compaction for structural integrity
Fill block cells and install perforated drainage at the correct slope
Cap your wall professionally for long-lasting protection

This tutorial includes critical techniques specific to slope retention, including how to avoid over-excavation, maintain consistent embedment, and ensure proper water drainage through wall drain systems. We explain why these details matter and how they prevent the settling and failure common in DIY slope retention projects.
