Using Shotcrete for Steep Slope Stabilization
Nov 30, 2016 · Learn how shotcrete, a sprayed concrete, can reinforce and protect roads and other infrastructure on steep slopes. Find out the benefits, uses and sources of shotcrete for slope stabilization.
Shotcrete has become attractive and holds potential to replace cast-in-place (CIP) concrete for elements like retaining walls and slope stabilization. However, this practice is still limited due to

Shotcrete is a wet- or dry-mix mortar with a fine aggregate (up to 23 mm, or 7/8 in) that is sprayed directly onto a slope using compressed air. Several applications may be needed to build the shotcrete up to the required thickness.
One of many ways to secure and stabilize highway slopes is by the use of fiber-reinforced shotcrete (FRS), usually along with either rock bolts or some other mechanical device drilled into the rock or slope.
Underground FAQs - American Shotcrete Association
Most shotcrete slopes are placed without moisture barriers and are constructed to ensure that water pressure does not build up behind the slope and create hydrostatic pressure on the backside of the shotcrete.
Reinforcing Infrastructure with Shotcrete: Applications in Slope ...
Oct 4, 2024 · Shotcrete is used in a vast array of applications where slope stability is paramount. These include: Highway and Railway Cut Slopes: Shotcrete helps prevent rockfalls and landslides that could impact traffic. Dam and Levee Faces: It provides a durable layer of protection and reinforcement for critical water infrastructure.
The use of shotcrete for slope and rock stabilization has increased substan-tially in the past few years. This paper explains why some design firms and contractors are switching from wire mesh and rebar to fibers. Reduction of material—FRS allows …
c. Slope and surface protection. Shotcrete is often used for temporary protection of exposed rock surfaces that will deteriorate when exposed to air. Shotcrete is also used to permanently cover slopes or cuts that may erode in time or otherwise deteriorate. Slope protection should be properly drained to prevent damage from excessive uplift ...
Innovative Shotcrete Applications for Geohazard Mitigation
Shotcrete is widely used for slope stabilization to prevent soil erosion, landslides, and rockfall. It provides a protective layer that reinforces slopes, ensuring their stability and reducing the risk of geohazards.
Slope Stabilization Methods: Classification and Construction
Learn about different techniques to stabilize slopes in civil and mining engineering projects, such as geometrical, hydrological, chemical, and mechanical methods. Find out how to use rock bolts, anchors, shotcrete, grouting, and other protection measures to prevent slope failure.
