Walls & Slopes

Nilex provides a variety of wall facings for its slope and retaining wall systems.

ARES® Retaining Wall System

ARES Wall Face

The ARES Retaining Wall System uses a precast concrete panel wall facing that is customized to meet project-specific architectural, structural, aesthetic and budget requirements.

Mesa® Segmental Retaining Wall (SRW) System

Mesa

The Mesa Segmental Retaining Wall (SRW) System features a unique positive mechanical connection between the masonry block facing unit and the geogrid reinforcement.

StoneTerra™

The patented StoneTerra™ Retaining Wall Block System offers an attractive architectural face and simple installation all at a sensible per square metre/foot cost.

SierraScape®

SierraScape® Wall Face SierraScape is the only wire-formed retaining wall system with a positive connection between the wire form and geogrid reinforcement. Finished facing options can include stone, shot-crete and vegetation.

Sierra® Slope Retention System

Sierra® Slope Wall Face

The Sierra Slope Retention System is a premier reinforced soil slope retention system designed to blend naturally with the surrounding environment.

Surficial Slope Stabilization

ARV

Nilex’s Anchor Reinforced Vegetation (ARV) system can be engineered to provide surficial slope stabilization to resist shallow plane failures that typically occur after heavy rain or during spring thaw.

ARES® Retaining Wall Systems

The ARES® Retaining Wall System marries geogrid reinforcement with pre-cast concrete panel facing units. A variety of treatments can be applied to the facing panels to achieve unique aesthetic looks and effects.

The components of the ARES wall system include:

  • Tensar soil reinforcement geogrids which create a reinforced soil mass
  • ARES steel-reinforced precast concrete panels
  • Full-height concrete panels delivered directly to your construction site with geogrid reinforcement cast into the panel at predetermined elevations and spacing
  • Full engineering and construction support services

ARES Retaining Wall Components

One of the key advantages of the ARES Retaining Wall System is that full-height panels can be delivered, erected and braced in one operation. This allows the backfilling process to proceed at its own schedule, unaffected by the schedules of wall facing delivery and installation.

Applications
MSE Walls & Slopes

 

Mesa®

The Mesa® Segmental Retaining Wall System combines the aesthetics, versatility and economy of segmental concrete block units with a unique, positive mechanical connection between the block and the geogrid reinforcement.

Segmented Wall System

The basic components of the Mesa Wall System include:

  • Tensar geogrids which create a reinforced soil mass
  • Mesa Segmental Blocks – aesthetically pleasing, high strength, low absorption concrete blocks
  • Mesa Connectors - unique locking connectors that mechanically connect the Tensar geogrids to the Mesa blocks Full engineering and construction support services

Reinforced Walls

Mesa’s unique, positive mechanical connection provides long-term durability, increased structural integrity and simplified construction. Mesa is particularly advantageous on projects involving heavy loading conditions, high traffic and/or high seismic activities.

StoneTerra™ (Alberta Only)

A retaining wall block that takes advantage of the positive attributes that specifiers and customers are trying to find. The patented StoneTerra System offers an attractive architectural face and simple installation all at a sensible per square foot cost. StoneTerra offers more possibilities with less effort.


Whether you are a homeowner, contractor, landscape designer or engineer/architect, StoneTerra is the right block for your next project.

Advantages:

  • Interlocking
  • Fast and simple installation
  • Can easily be set with small equipment
  • Curved or straight walls
  • Ability to build in limited space
  • Cost effective

The StoneTerra Wall System units offer an easy-to-build, structural retaining wall. With eight different block styles available, the designs are limitless.

SierraScape®

SierraScape® is a cost-effective alternative to conventional retaining wall systems. SierraScape is the only wire-formed retaining wall system with a positive connection between the wire form and geogrid reinforcement. The flexible nature of SierraScape makes is it well suited for applications prone to differential settlement or seismic activity.

Sierra Scape

The basic components of the SierraScape system include:

  • Tensar uniaxial geogrids, which create a reinforced soil mass
  • Tensar biaxial geogrids which provide secondary reinforcement and maintain facing alignment during construction
  • Geotextiles help contain fill at faceSierraScape connection rods facilitate the mechanical connection between geogrid and facing unit
  • SierraScape facing units provide facial stability during placement and compaction of the fill material. (Facing unit dimensions: 457mm x 457mm (18" x 18") )

Two Stage Walls

When differential settlement is a concern, the SierraScape system has been constructed in two stages. In step one, the SierraScape structure is constructed with a "temporary" soil/fabric facing and allowed to settle over a specified period of time. In step two, a permanent facing (concrete panel or other) is attached after differential settlement has occurred.


Pressure Relief Applications
The SierraScape system can also be used for pressure relief applications to eliminate lateral loads against below-grade structures. SierraScape provides a faster, more affordable alternative to large cast, in place foundations and supports soil and building loads for below-grade construction.

Applications

MSE Walls & Slopes

Sierra® Slope

The Sierra Slope system is the "green" structural alternative to retaining walls. Sierra Slope maximizes the use of valuable land and is lower in cost than concrete retaining walls. Sierra Slope also has the added benefits of natural aesthetics and flexibility.

Vegetated Slope

 

The basic components of the Sierra Slope system include:

  • Tensar Uniaxial Geogrids which create a reinforced soil mass
  • Tensar Biaxial Geogrids provide secondary reinforcement to ensure surficial stability of the slope structure
  • A Site-specific facing system provides a multiple of aesthetic facing options, including bio-engineering (In Canada only: dimensions for Sierra Slope Welded Wire Forms (when required) are 508mm x 508mm (20" x 20") )

Step Wall

Sierra Slope is a smart choice for grade separation systems. Sierra Slope costs 30 to 60 per cent less than concrete wall systems, and it enhances property values with naturally vegetated, graffiti-resistant facing options. A SierraSlope system can be constructed without select/specialized backfill and is well suited to sites prone to differential settlement.

Surficial Slope Stabilization

Nilex’s Anchor Reinforced Vegetation (ARV) system is a durable, flexible armouring system for severe erosion and surficial slope stability challenges. Constructed of a woven three-dimensional High Performance Turf Reinforcement Mat (HPTRM), the ARV system provides a lightweight protection layer that is securely anchored with earth percussion anchors for long term design life.

Slope Stabilization

For structural applications, the ARV system can be engineered to provide surficial slope stabilization to resist shallow plane failures that typically occur after heavy rain or during spring thaw.

Anchor Reinforced Vegetation Growth

Advantages:

  • Durable, flexible armoring system
  • Withstands extreme hydraulic stresses
  • Resists non-hydraulic event damage
  • Stormwater Best Management Practice (BMP) proven to reduce erosion and reinforce vegetation for low-impact, sustainable design
  • Easy to install
  • Aesthetically pleasing and cost effective when compared to conventional methods such as rock riprap and concrete paving

Nilex’s ARV System can also be used in non-structural applications where additional factors of safety are required, including protection from earthen levees from storm surge and wave overtopping and stream, river from scour and erosion.
