Featured Project Profiles

  • Riverlite® Solves Louisiana Home's Settlement Issues

    Riverlite® Solves Louisiana Home's Settlement Issues

    Riverlite takes on the challenge of land settlement for one distressed homeowner in a New Orleans community.

    As specified by Andre Monnot with Principal Engineering, Burlette Services, pumped Big River’s Riverlite® aggregate under the homeowner’s house to correct several feet of settlement which had occurred over a four-year period.

  • Riverlite® Key Part of Critical Port's Expansion

    Riverlite® Key Part of Critical Port's Expansion

    Big River’s Riverlite®, the lightest structural aggregate available in the USA, is being used to create additional port space at the Port of Fourchon.

    Riverlite® lightweight aggregate is providing structural and economic advantages for this latest expansion project at the Port. For the past two decades, Riverlite® has been used as backfill to create useable land at the facility.

  • Riverlite® Used As Backfill Reduces Load on Culvert

    Riverlite® Used As Backfill Reduces Load on Culvert

    Designers of a major interchange under construction just north of Birmingham, Alabama had an engineering challenge.

    Presently known as “Corridor X”, the 169-million dollar project is being built by Archer-Western Contractors of Atlanta. The addition of two new traffic lanes posed a challenge to designers at the Alabama Department of Transportation.

  • New VA Hospital Gets Dual Advantages from Use of Riverlite®

    New VA Hospital Gets Dual Advantages from Use of Riverlite®

    Riverlite® is providing structural and cost saving advantages for the new VA Hospital in New Orleans, Louisiana.

    Project Legacy, as the project has come to be called, is one of the single largest construction project in the history of the city of New Orleans. The multi-building campus will cover twelve city blocks and will include buildings for Inpatient, Diagnostic and Treatment, Outpatient, Transitional Living and Rehabilitation, Research, Administration, Central Energy Plant and two separate parking structures.

  • Riverlite® Used in Lambeau Field Expansion

    Riverlite® Used in Lambeau Field Expansion

    Structural lightweight concrete made with Riverlite® is being used in the $143-million expansion of Green Bay Wisconsin's Lambeau Field.

    The Lambeau Field Stadium Improvement Project includes two new gates, a rooftop viewing platform in the north end zone and 6,700 new seats in the south end zone. Those new seats will be added in four levels. General seating, along with new restrooms and concessions, now greet Green Bay Packer fans.

  • HydRocks® Key Component of Nashville Green Roof

    HydRocks® Key Component of Nashville Green Roof

    There’s a meadow five stories above the busy city streets of Nashville complete with green grass and rolling hills. This green space in the sky is actually the roof of a new convention center in the Music City.

    Ordinarily, rains pouring over the massive 1.2 million square foot building would drain into the city’s storm water system. But rather than tax the already strained system, some of which dates back to the 1880’s, most of the storm water landing on the new Music City Center will be retained by its specially designed roof.

  • Internally Cured Concrete Used in Fullen Dock Expansion

    Internally Cured Concrete Used in Fullen Dock Expansion

    An outdoor industrial slab in Memphis, Tennessee is being closely watched as a pilot project for internally cured concrete.

    Located at Fullen Dock & Warehouse along the lower Mississippi River, this 52-thousand square foot slab is one of the largest outdoor holding areas ever built to utilize internally cured concrete.

  • Q-LITE® Used in New Tennessee High School

    Q-LITE® Used in New Tennessee High School

    A new high school under construction in a fast growing Middle Tennessee community will use around 450,000 lightweight block produced by Southland Brick and Block of Murfreesboro.

    The 208,000 square foot facility was designed by a local firm, Kaatz, Binkley, Jones & Morris. KBJM Architects is based in Mount Juliet. Nashville’s RG Anderson Company is supervising construction of the massive $37-million facility that is scheduled for completion in May 2014.

  • Riverlite® Aids in Biloxi Marsh Restoration

    Riverlite® Aids in Biloxi Marsh Restoration

    Oversized geotextile bags filled with Riverlite® are being used to protect the shoreline and restore marshes in the Biloxi Wildlife Management Area, a vital coastal ecosystem that protects the city of New Orleans, LA.

    The Biloxi Marsh project is located along a 7-mile stretch of the southeastern shoreline of Lake Borgne and the Biloxi Wildlife Management Area in St. Bernard Parish, Louisiana.

  • Lightweight Aggregate Provides Stable Surface for Minnesota Project

    Lightweight Aggregate Provides Stable Surface for Minnesota Project

    A newly expanded road through a busy Minneapolis-St. Paul suburb is relying on lightweight aggregate from Big River Industries to provide a smooth ride for commuters.

    Maple Grove, Minnesota’s Bass Lake Road started out a simple 2-lane highway but has become a vital link for residents of this fast growing community. To accommodate all the traffic, a project to widen the road into a median-divided four lane highway was recently completed.

  • Riverlite® Speeds Up SC Road Construction Time

    Riverlite® Speeds Up SC Road Construction Time

    Just outside of Myrtle Beach, South Carolina, Farrow Parkway began as a simple cow path cutting across rural farmland. Today, this parkway has become one of the state’s most heavily traveled roads.

    A major effort to redesign and alleviate traffic congestion for drivers at the intersection of Farrow Parkway and U.S. Highway 17 Bypass is underway and Riverlite® lightweight aggregate from Big River Industries is helping speed up construction time.

What is Lightweight Aggregate?

  • Expanded Clay Lightweight Aggregate has a long track record of quality and performance.

    Since its development in the early 1900s, LWA is composed of selectively mined clay fired in excess of 2000° F. The result of this carefully controlled manufacturing process is a high quality, lightweight aggregate that is inert, durable, tough, stable, highly insulative and free draining, ready to meet stringent structural specifications. The LWA material is processed to precise gradations and used in asphalt road surfaces, concrete bridge decks, high-rise buildings, concrete masonry and geotechnical applications.

  • When used in concrete and masonry, LWA increases the fire resistance of a given thickness of concrete and provides more structural stability when exposed to high temperatures.

    Conversely, lightweight concrete provides the required fire resistance rating with less concrete, because it slows the transfer of heat through the concrete. This translates to thinner walls and floors, reducing dead loads and resulting in less reinforcing steel and smaller supporting beams, columns and foundations.

  • When bonded to asphalt, LWA creates an advanced road surface that is safer, and more economical.

    Safety is increased due to the superior skid resistance (wet or dry) of road surfaces made with LWA. This high skid resistance is maintained throughout the road's service life because of the aggregate's rough micro surface texture. Pavements made with normal weight aggregates (especially those using limestones, dolomites and gravel) may polish or become slick under the action of traffic and lose a large percentage of their skid resistance. Lightweight aggregates do not polish as they wear.
