How Long Will Decomposed Granite Last?Expert Guide

When homeowners or landscapers consider outdoor design, one common question arises: how long will decomposed granite last? This natural material has become a popular choice for pathways, patios, and landscaping because of its affordability, durability, and earthy appeal. Unlike concrete or asphalt, decomposed granite (DG) offers a softer look that blends with nature while still being strong enough for regular use.

At SF Marble and Granite, we know the importance of choosing materials that balance aesthetics with long-term performance. Decomposed granite is one of those versatile materials. Its lifespan depends on factors like the type of DG you choose, whether it is stabilized, and how well it is installed. In this article, we’ll explore the durability of decomposed granite, installation tips, its different applications, and also share insights into our backsplash installation in Lowell and granite installation in Lowell services for enhancing indoor and outdoor spaces.

Understanding How Long Decomposed Granite Will Last

The durability of decomposed granite largely depends on the type and where it’s used. Generally, decomposed granite can last seven to ten years before it requires refreshing. With proper installation and maintenance, its lifespan can extend well beyond a decade.

• Stabilized decomposed granite tends to last longer because stabilizers like resins or binders help it resist erosion.

• Loose decomposed granite may shift more easily, especially in high-traffic areas or rainy climates.

• Regular maintenance, such as raking and adding a fresh top layer, can help prolong its appearance and performance.

So, how long will decomposed granite last? The answer varies, but with correct installation and care, you can enjoy its natural beauty for many years.

Benefits of Using Decomposed Granite in Landscaping

Choosing decomposed granite offers homeowners many advantages compared to other hardscaping materials.

When asking how long will decomposed granite last, the answer lies in its resilience to foot traffic, weather, and time when properly cared for.

Stabilized Decomposed Granite for Longevity

One of the best options to extend lifespan is stabilized decomposed granite. Stabilizers are mixed into the granite particles, binding them together to prevent excessive movement.

Creates a Firmer Surface

A stabilized surface is smoother and more solid, making it wheelchair- and stroller-friendly while still maintaining a natural look.

Steps to Install DG:

1. Clear the area – Remove grass, weeds, or debris.

2. Add a base layer – Use Class II road base or crushed stone for drainage.
