​how to install geogrid for retaining wall？

What is a Geogrid Retaining Wall ？

A geogrid retaining wall is a modern, engineered structure designed to hold back soil and prevent erosion by using a specialized geogrid fabric for soil reinforcement. Unlike traditional retaining walls that rely solely on their mass for stability, geogrid retaining walls enhance soil strength by integrating durable geogrid layers within the backfill. This creates a mechanically stabilized earth (MSE) wall – a bombproof combination of soil and geogrid that works together to resist pressure.

How Geogrid Reinforces Soil

Geogrids are strong synthetic grids made from polymers that act like a tough skeleton inside the soil. When installed correctly, they:

• Lock soil particles together
• Distribute loads evenly
• Prevent soil from shifting or sliding
• Improve overall wall stability and lifespan

This means the surrounding soil becomes a powerful, reinforced mass that makes your wall safer and more reliable over time.

MSE Walls vs Gravity Walls

Gravity retaining walls rely purely on their heavyweight and size to hold back soil. Made from solid materials like concrete or stone, they must be massive and heavy to resist pressure, making them expensive and bulky.

In contrast, MSE walls using geogrids use soil reinforced with geogrid layers to create a lightweight but incredibly strong structure. These walls:

• Require less material and space
• Are faster and easier to build
• Allow taller, slimmer designs without sacrificing safety

For projects demanding savvy engineering and cost-effective solutions, geogrid retaining walls offer unmatched performance and durability. They bring the ultimate blend of strength and efficiency, making them the go-to choice for today’s construction and landscaping pros.

When should geogrid retaining walls be used?

A geogrid retaining wall uses strong, grid-like materials called geogrids to reinforce soil, making the wall more stable and durable. But when should you actually consider using geogrid for your project? Here are some key triggers to look out for:

• Steep or unstable slopes where soil is prone to sliding
• Heavy loads behind the wall like driveways, parking lots, or buildings
• Poor soil conditions such as loose or sandy soils that need extra support
• Limited space that doesn’t allow for a wide gravity retaining wall base
• Height requirements over 4 feet, where stability demands increase
• Drainage challenges that require better soil stabilization and water flow control
• Long-term durability goals for walls expected to handle heavy use or weather changes

If your project checks any of these boxes, a geogrid retaining wall with proper soil reinforcement can save you time, money, and headaches by preventing wall failure and erosion. Using the right geogrid layers and backfill compaction makes all the difference in creating a strong, lasting wall.

Step by Step DIY Geogrid Retaining Wall Installation Guide

Building a geogrid retaining wall yourself can save money and give you full control over the project. Here’s a straightforward DIY guide to get you started with your geogrid retaining wall installation:

1. Plan and Prepare the Site

• Clear the area of debris and vegetation.
• Mark the location and outline the wall’s footprint.
• Make sure the ground is level for a solid base.

2. Excavate and Build the Base

• Dig a trench about 6-12 inches deep depending on the height of your wall.
• Fill the trench with compacted crushed stone or gravel to create a stable base.
• Use a plate compactor or hand tamper for even compaction.

3. Install the First Layer of Retaining Wall Blocks

• Lay the first row of blocks or segmental retaining wall units.
• Make sure blocks are level and firmly pressed into the base.

4. Place the Geogrid Layers

• Cut geogrid fabric to fit the width of the wall plus a few extra inches.
• Lay the uniaxial or biaxial geogrid horizontally behind the first block row and extend it back into the soil.
• Secure the geogrid under each layer of blocks, following the manufacturer’s recommended spacing between layers.

5. Add Backfill and Compact

• Use clean, granular backfill material behind the wall.
• Compact the backfill in 6 to 8-inch layers to ensure proper soil reinforcement and stability.
• Make sure to keep the geogrid layers tight and flat during backfilling.

6. Repeat Layers and Geogrid Installation

• Build up the wall by repeating block placement, geogrid installation, and backfill compaction.
• Check the wall’s alignment regularly to keep it straight and consistent.

7. Finish with Drainage and Capstones

• Install drainage pipes or gravel behind the wall to prevent water buildup.
• Place capstones or finishing blocks on top for a clean, polished look.

Tips for Success

• Always follow MJY’s geogrid specifications for your wall size.
• Proper compaction is critical for long-lasting geogrid soil stabilization.
• Don’t rush the process — layering and compacting carefully will pay off in stability.

This simple DIY process using segmental retaining wall geogrid layers ensures your retaining wall is solid, reliable, and built to last.

Choosing the Right MJY Geogrid Comparison and Sizing Chart

Picking the right MJY geogrid for your retaining wall means matching the product to your project’s soil conditions, wall height, and load requirements. To help simplify this, here’s an easy-to-read comparison and sizing chart based on common geogrid types and their best uses.

MJY Geogrid Type	Strength (kN/m)	Best For	Soil Reinforcement Type	Typical Wall Height	Key Features
Uniaxial Geogrid	20 – 80	High load, steep walls	Soil reinforcement geogrid	6 – 20 ft	Directional strength, excellent pullout resistance
Biaxial Geogrid	15 – 50	Moderate loads, segmental walls	Geogrid fabric for retaining walls	3 – 12 ft	Equal strength both directions, easy installation
MJY High Strength	50 – 100+	Large commercial projects	Geogrid soil stabilization	15+ ft	Engineered for max durability and soil locking

How to Use This Chart

• Wall height: Choose a geogrid strength based on your retaining wall’s height.
• Load type: Uniaxial grids handle heavier loads in one direction—perfect for tall or steep walls.
• Soil type: For softer or less stable soils, gravitate toward high strength or biaxial options for better soil reinforcement.
• Installation style: Segmental retaining walls often pair well with biaxial geogrids.

Pro Tip

Always consider geogrid backfill compaction and layering recommendations to maximize your wall’s lifespan and stability. Proper placement of geogrid layers can reduce settlement and drainage issues.

MJY’s sizing chart is designed to take out the guesswork so you can get the exact geogrid needed for your retaining wall — saving you time and money in the long run.
