Global Stability has successfully constructed millions of square feet of earth retention structures in support of commercial, retail, industrial, and municipal development projects throughout the Southeast.

We work with developers, contractors, and design professionals to construct retaining walls and other structures that are economical, functional, and aesthetically pleasing. To deliver a top-quality product, we often make design recommendations to substantially reduce the cost of earth retention without sacrificing the developer’s vision.

Types of Retaining Walls:

Segmental Retaining Walls
Segmental retaining walls (SRW’s) are gravity walls that rely primarily on their mass (weight) and geogrid reinforcement for stability.  The complete wall system consists of concrete masonry units which are placed without the use of mortar (dry stacked), and rely on a combination of mechanical interlock, geogrid reinforcement, and mass to prevent overturning and sliding. The units can also be used in combination with horizontal layers of soil reinforcement to extend the backfill and increase the effectiveness and weight of the gravity mass.

Reinforced Slope
A reinforced slope wall is a technique whereby tensile elements are placed in the soil to improve stability and control deformation. To be effective, the reinforcements must intersect potential failure surfaces in the soil mass. Strains in the soil mass generate strains in the reinforcements, which in turn, generate tensile loads in the reinforcements. These tensile loads act to restrict soil movements and thus impart additional shear strength.

This results in the composite soil / reinforcement wall system that has significantly greater strength than the soil mass alone.  Reinforced slope walls can be steepened with a vegetative face or designed for pond applications stone face with galvanized baskets.

Gabion Walls & Mattresses
Gabion Walls are free-draining walls that are constructed by filling large galvanized steel baskets with rock. They are used in many applications as one of the most cost effective structural walls available. Flexibility is an important benefit of any gabion wall structure. Since the baskets are constructed of galvanized mesh wire and filled with rock, the flexibility allows it to withstand pressure without deforming, cracking, or breaking as in the case of concrete and other materials.

Gabion Mattresses is a flexible woven mesh system with many advantages over block walls, reinforced concrete, or concrete mattresses. A flexible material, gabion mattress can deform to differential settlements, while maintaining their functionality.

Granite Rubble Wall
A granite rubble wall is built with rough, raw building stone set in mortar, laid in irregular courses. It may appear as the outer surface of the stone wall or may fill the core of a wall, which is faced with unit masonry such as brick or cut stone.

Gravity Walls
A gravity retaining wall relies on the weight of the wall itself and the contents therein for stability. A gravity wall typically consists of large block precast modular concrete units and is often referred to in the industry as Big Block walls such as Redi-Rock Wall and Stone Strong Wall.

A common RediRock Wall system used today to make innovative use of soil back-fill is Forix. Larger gravity walls targeted toward the highway, rail, and large commercial industrial properties is Gravix.

These walls traditionally have shorter embedment depth when compared to conventional MSE walls (mechanically stabilized earth). Tight job sites and walls close to property lines or utilities may find gravity walls more economical and feasible than conventional retaining walls.

Global Stability is partnered with CHANCE^® Civil Construction, the premiere supplier of helical piles and helical anchors in the industry, to provide a full range of foundation construction services. We install helical piles for deep foundation, underpinning, and foundation repair as well as helical anchors for both temporary and permanent earth retention.

As a CHANCE^® certified installer our work is backed by CHANCE’s^® 30 year “Piece of Mind” warranty.

Types of Helical Piers & Anchors:

Helical Piers – Deep Foundations
The helical anchor piles are a segmented deep foundation system with helical bearing plates welded to a central shaft. Load is transferred from the shaft to the soil through the plates. As a result of the true helical shape, the helices do not auger into the soil but rather screw into it with minimal disturbance.

Helical Piers – Underpinning
Helical pier underpinning is used to stabilize foundations or to retrofit an existing building to increase load capacity. Piles are installed at intervals around the perimeter at affected locations. Independent of the structure, the piles are extended to depths, which attain the installing torque correlated to the required load bearing capacity.

Special brackets are located where needed around the perimeter and secured to the concrete foundation. A pile is then torqued into the soil and connected to each bracket. The brackets permit lifting by hydraulic jacks. Tightening the nuts on the vertical bolts of the bracket locks off the load.

Helical Piers – Tiebacks
Helical tiebacks are a pre-engineered system for earth retention applications. The success of the helical anchor tieback system is based on decades of similar use of anchors by electric utilities. The proven reliability and engineered predictability of these tiebacks produce an earth-retention system that is efficient, economical and hassle-free.

Helical tiebacks are installed by rotating the anchor into the ground with common rotary drilling equipment. Once the minimum depth is obtained the capacity can be determined by reading the installing torque and correlating it to the holding capacity ratio. Capacities up to 200,000 pounds per anchor are obtainable with this system.

Global Stability offers premium services for pipeline support and stabilization, as well as pipeline easement protection, maintenance, repair and erosion control.

Services for specialty civil sites include grading, remedial repair, intricate site work, recreational facility construction, and athletic field development. We convert difficult construction projects into successful builds.

We offer retaining wall repair and have successfully constructed millions of square feet of earth retention structures in support of commercial, retail, industrial and municipal development projects throughout Georgia, Florida, Alabama, Tennessee, South Carolina, and North Carolina.
