This article was created using automation technology and thoroughly fact-checked and edited by HomeAdvisor Editor Ryan Noonan.

When you ask who installs riprap, hire a landscape grader or other licensed contractor with grading and rock‑laying expertise. Shorelines are regulated, so installers need proper licensing and permits to work legally and protect your property.

Get at least three bids and confirm each contractor’s experience with residential riprap projects and how their work has held up over time.

Benefits of Hiring a Landscape Grader to Install Riprap

Landscape graders design and build riprap systems that stop soil erosion and protect water‑adjacent property. They grade slopes, compact soil, add geotextile fabric, and select rock sizes that interlock for long‑term stability. Professional installation looks good and lasts, reducing risk to your shoreline and the surrounding landscape.

• Achieves a stable, no‑steeper‑than‑3:1 slope for reliability

• Compacts subgrade to support the weight of tons of rock

• Places geotextile fabric to reduce soil loss beneath rock

• Sizes and lays stone for tight interlock and strength

• Staggers rock patterns for consistent contact and stability

• Follows permits and shoreline regulations for compliant work

• Operates heavy equipment safely for precise installation

• Builds long‑lasting protection for water‑adjacent property

• Designs solutions for varied shoreline and erosion conditions

• Delivers a neat, attractive look that complements the site

If your shoreline project involves complex grading, heavy equipment, or strict permitting, you might want to consider a landscaper near you to ensure the job is done safely and in compliance with local regulations.

Can I Hire a Seawall Contractor for Riprap Installation?

Seawall contractors can install riprap when they are experienced with grading and rock‑laying methods. They work with materials such as concrete, vinyl, treated wood, steel, and rock, and understand local shoreline guidelines. Ask for references from past residential riprap projects to verify quality and durability.

How Do Landscape Graders Install Riprap?

Pros follow a step by step process when installing riprap to ensure a safe and secure installation.

1. Prepare and grade the slope: Excavate to a maximum 3:1 horizontal‑to‑vertical slope and clear debris and vegetation.

2. Compact the soil: Densify the base to support the weight of riprap.

3. Add geotextile fabric: Secure fabric to limit soil loss beneath the rock.

4. Lay gravel layer: Install gravel or small stones for added stability.

5. Place large rocks: Stagger placement, mix shapes and sizes, and ensure solid rock‑to‑rock contact; type B/type 2 stones (12–24 inches) suit mild erosion.

6. Fill gaps: Chink voids with smaller stones to lock the structure.

7. Install border: Add a decorative or containment edge if needed.

How Much Does Installing Riprap Cost?

Installing riprap costs $70 to $400 dollars per linear foot. Your total depends on project length as well as your property’s condition and slope. These factors influence excavation needs, grading, and the amount of rock required. Compare at least three bids to evaluate scope, methods, and timelines for your shoreline.
