Reinforced Earth Company (RECo) products

Reinforced Earth is The Reinforced Earth Company’s flagship MSE retaining wall product, first introduced in the United States in 1971.

GeoMega is an MSE wall system whereby the soil reinforcing elements consist of high-strength extensible geosynthetic reinforcing strips (GeoStrap®) connected through a patented sleeve embedded in precast concrete facing panels. GeoMega MSE walls are ideal for construction in sea water and other aggressive environments.

Piano Wall is an MSE wall with integral precast concrete facing and traffic barrier. It is ideal for eliminating the process of a separate installation of traffic barrier and moment slab on top of a retaining wall. Especially over a long stretch of road, considerable time will be saved. The name Piano Wall is derived from the shape of the precast facing unit’s cross section.

TerraTrel is a wire-faced MSE wall system, consisting of inextensible High-Adherence (HA) steel reinforcing strips or ladders with a bolted connection to the wire mesh facing. The system provides a cost-effective solution for wall applications where aesthetics is not a critical requirement, precast concrete facing is not necessary, or heavy lifting is not feasible. TerraTrel is also ideal for temporary structures used in roadway widening, bridge phasing, and surcharges for inducing settlement.

GeoTrel is a wire-faced temporary MSE wall system, consisting of high-strength extensible geosynthetic reinforcing strips (GeoStrap™) connected to wire mesh facing. The system provides a cost-effective solution for temporary wall applications where aesthetics is not a critical requirement, precast concrete facing is cost prohibitive, or heavy lifting is not feasible. GeoTrel is ideal for temporary structures used in roadway widening, bridge phasing, and surcharges for inducing settlement.

The Reinforced Earth Company is excited to add T-WALL®, formerly of The Neel Company, to our list of proven retaining wall solutions. T-WALL® is a gravity retaining wall system, consisting of modular precast concrete units and select backfill. The system is a simple proven solution for grade separation on highway, bridge, railroad, water, commercial applications, and more. The concrete units are facing with monolithic perpendicular stems, forming the shape of a “T”. The stems internally stabilize the wall, providing pullout resistance against the lateral earth pressure exerted on the back of the facing. The result is a modular gravity structure with no mechanical connections necessary.

TechWall is a precast counterfort retaining wall system consisting of full-height wall facing units secured to a cast-in-place footing. The facing units are each cast with a counterforts on the rear side.

FanWall is a free-standing sound barrier consisting of full-height or stacked concrete panels, joined by simple stainless steel wire rope connections. The wall’s stability is obtained with the proper combination of height, panel thickness and offset depth. The offset depth results in a trapezoidal pattern, giving the wall it’s fan-like appearance and resistance to overturning.

Shored Reinforced Earth is a Mechanically Stabilized Earth (MSE) retaining wall that is built in front of an existing retaining wall, rock face, stabilized slope, or other structure, and uses the existing structure to reduce the lateral earth pressure on the new wall. This method of design can be used when there is not enough distance available behind the proposed wall face to build an MSE wall with a conventional or trapezoidal base width.

The engineering benefits of arches have been known for thousands of years, and explored most famously by the ancient Roman Empire. Materials and methods of design have evolved over the years, but the basic principles have remained the same. The overburden load is carried along the arch from the top down to both ends, in pure compression, with zero or minimal tension in the arch member. It allows for a very efficient design of the arch span, and use of materials that typically do not have a high tensile capacity.
