Mesa ® Walls provide the dependability engineersrequire, the efficient installation contractors havecome to expect, and the aesthetics owners andarchitects demand in the industry today.A Single-Source SolutionFor over a decade, the Mesa® Retaining Wall Systems have beenthe retaining wall solution of choice for many architects andengineers. One of the only concrete segmental retaining wall(SRW) systems with a proven, positive, mechanical connection,the Mesa Systems offer superior and cost-effective solutionsfor your structural and landscaped retaining wall needs in thecommercial, industrial, residential and transportation markets.With a network of licensed independent block manufacturersthroughout the United States, Canada and Latin America,the Mesa Systems have become a new standard in SRWtechnology. Designed as a truly integrated solution, they arethe only SRW system where the block, geogrid and connectorhave been developed by one company. Unlike other SRWs, thecomponents of a Mesa Wall have been specifically designedto work together for optimum efficiency and performance.High-strength, low-absorption concrete units, high-shearstrength connectors and <strong>Tensar</strong>® Geogrids all work togetherto form a mechanically stabilized earth (MSE) system that canmeet or exceed the industry standard. In fact, as a result of thehigh connection strength and reliability of the system,* core fillis rarely needed. Using less core fill results in greater projectsavings through less imported stone and less labor.If you’re looking for long-term durability, increased structuralintegrity and simplified construction, all at lower costs thanmost conventional alternatives, specify the Mesa RetainingWall Systems on your next project.*Core fill is defined as the aggregate fill within the open void space of anSRW Block. Core fill is suggested for wall segments that form convex curveswith a radius less than 25 ft (7.6 m) and 90° outside corner units.Mesa® Systems’ ComponentsComponent<strong>Tensar</strong> GeogridsMesa Segmental UnitsMesa ConnectorsFunctionHigh-density polyethylene (HDPE) structural geogrids internally reinforce the fill materials. Inert tochemical degradation, they can be used with non-select fill or even recycled concrete.High-strength concrete block with a compressive strength that exceeds the National Concrete MasonryAssociation (NCMA) standards (>4,000 psi) (27.6 MPa).Unique locking connectors are designed to mechanically connect the <strong>Tensar</strong> Geogrids to the Mesa Units.Provide a low-strain, end-bearing connection that is not dependent on friction for structural integrityand allow walls to be built near vertical or with a 5 ⁄8" (1.6 cm) setback.Full Engineering and Construction ServicesDetailing, design, site assistance and stamped drawings for each Mesa project upon request.8
The Connection You Can Count OnTested Transportation <strong>Solutions</strong>The long-term performance of any retaining wall system istested most rigorously in the public transportation market.Differential settlement, traffic barriers and seismic loads cantest the strength of any retaining wall, so connection strengthmust be reliable. The Mesa® Connectors were specificallydesigned to meet these long-term performance demands,providing a mechanical connection where it’s needed most –at the face. The system and connection components are largelyunaffected by abrasion, tearing or hydrolysis – factors that canundermine the performance of frictional systems using awoven polyester reinforcement. When specifying a Mesa Wall,you are assured that the system’s structural components arereliable and designed for long-term performance.Mesa Systems –Segmental Retaining WallCreative Commercial ApplicationsWhen designing for commercial applications, the need tocombine creative looks with practical installations becomes anecessity, while at the same time maintaining the bottom line.That’s where the Mesa Systems can help. By coexisting withboth nature and industry, a Mesa Wall combines creativity withstructural stability, providing the ideal solution for almost anycommercial application.Reliable Residential ProjectsWhether you’re increasing useable land or improving propertyvalue, the Mesa Systems can solve your most challenging gradechange requirements with a full line of segmental retaining wallproducts. From building large structural walls for multi-familyhomes to tiered garden walls in your own backyard, Mesa Unitsblend effortlessly with the natural surroundings of most any site.<strong>Tensar</strong> Uniaxial Geogrid12" (min.)
