Retaining walls play an important role in maintaining commercial and residential properties. These structures prevent dirt from moving downhill in areas requiring extra support and reduce erosion by managing water runoff. Learn more about the benefits and best practices for rip rap seawall design.
Benefits of a Rip Rap Retaining Wall
Commercial and residential property owners build retaining walls because they provide various benefits, including:
Improved Flood Control
Heavy rains can cause flooding in some landscapes, increasing the risk of significant property damage. Constructing a retaining wall in a flood-prone region holds the soil in place and reduces flood risk.
Enhanced Appearance
Retaining walls are beneficial for business owners because they increase their property’s visual appeal. This increases foot traffic and improves the customer experience.
Increased Usable Space
Hills and mounds make landscaping difficult. Installing a rip rap retaining wall enables homeowners to create terraces and maximize functional space in their yard.
Reduced Maintenance
Water runoff carries rocks and other debris through a property. Retaining walls reduce runoff and minimize cleanup after storms.
Types of Rip Rap
The type of rip rap you use for your retaining wall depends on your property’s conditions. Here are the four main types of rip raps for retaining walls.
Type A
Type A rip rap is hefty and remains in place while stacked, making it ideal for steep slopes. These limestone rocks measure 18 to 30 inches and are the largest available product. They’re primarily used for protecting large areas from drainage issues, including bridges and river banks.
Type B
Type B is the second largest limestone rip rap rock, measuring 12 to 24 inches. Landscapers and construction companies use this variety for high-velocity slopes that experience minor erosion.
Type C
Type C ranges from 6 to 18 inches and is the most popular type for residential retaining walls because it’s ideal for medium-sloped properties.
Type D
Type D is the smallest rip rap variation. Because of its small size, this rock is rarely used for controlling erosion but is often applied as a base for retaining walls.
