Precast Panel Walls (Stabilized Earth Walls)

Precast Panel Walls (also known as stabilized earth walls, mechanically stabilized earth walls, MSE retaining walls, or reinforced earth walls) use precast panels with galvanized steel wire mats to reinforce a retained soil mass. This technically-sound and well-proven system is composed of alternating layers of soil reinforcement and select backfill to create an extremely stable reinforced structure that is easily adaptable to meet the structural and aesthetic demands of today’s infrastructure projects. Panels are available in a variety of sizes, colors and textures, as well as custom design. With Big R Bridge's project-specific, engineered approach, the fascia panels are prefabricated to insure quick delivery and easy attachment.

Features Benefits
Easy and quick to erect Ease construction schedule pressures
Variety of Finishes/Logos Can be used in rural, industrial or urban settings
Safisfy architectural or functional needs
Various Shapes & Sizes of Panels Easily adaptable to curves, angles, steps
Can cast standard panels ahead of project approvals
Increased Durability Can be designed to 75 or 100 years
Can be designed for high dead load and/or high surcharge loading
Vertical joint alignment Can accommodate differential settlement without damaging panels
Impact Resistant Used for mining applications where possibility of impact to wall is a concern
Prefabricated Components Faster Installation
Components just have to be assembled on-site
Plant Manufactured Minimized on-site quality control
Vertical construction vs. Batter Our walls do not require a batter and can be constructed vertically which means corners and curves are easier to build in the field.
