What Are the Factors That Impact the Cost of Boulder Retaining Walls?

Table of Contents

When you think of adding a boulder retaining wall to your property, many factors can influence the cost. Understanding these factors can help you manage your budget and ensure that you’re getting the most value for your investment. Let’s dive into the various components that can affect the price.

Height of the Wall

The height of the boulder retaining wall plays a crucial role in determining its cost. Generally, the taller the wall, the more materials and labor are needed. A higher wall also requires more engineering considerations to ensure its stability, leading to additional costs.

Choice of Rock

The type of rock you select can significantly impact the cost. For example, a Fieldstone boulder might be less expensive than utilizing trap rock. The aesthetics, durability, and availability of the rock can also influence its price.

Site Access

Access to the site where the wall will be built is a pivotal factor in determining the cost. If there’s room to get to the site or area easily with machinery, costs may be lower. In contrast, if obstructions need to be removed or special accommodations made for equipment access, this can raise the cost.

Excavation Needs

The amount of excavation needed for the wall can play a significant role in its cost. Digging deeply into a hill or removing vast amounts of soil can add to the expense, especially if the soil has to be transported away. Conversely, creating a flat area by filling in behind the retaining wall, requiring fill material, can also influence the price.

Topside vs. Bottom Side Construction

Whether the equipment is working from the top side of the wall (reaching down below) or from the bottom side (facing the front of the wall) can make a difference in cost. Building a wall from the top side can be more time-consuming, translating to higher labor costs.

Expertise and Equipment

The combination of the expertise of the contractor and the equipment they use can dramatically influence the cost of a boulder retaining wall. Using advanced tools, like rotating grapples on the ends of excavators, can be a faster and safer method. However, this efficiency is counterbalanced by the need for well-trained operators. It might take longer for operators to gain the required training and expertise, but once they do, they can install walls more efficiently, potentially at a lower cost.
