Lightweight geotechnical fill
HIGH-STRENGTH DURABILITY
LIGHTWEIGHT GEOTECHNICAL FILL
Numerous geotechnical engineering problems, and the conversion of unstable soft soil into usable land, have been solved with Buildex® lightweight aggregate. Approximately half the weight of common fills, it offers many advantages:
• Predictable high internal friction angle
• Reduction of lateral forces by more than one-half
• Permanent non-degradable insulation around water lines and steam lines, and other thermally sensitive elements.
USES FOR Buildex® lightweight aggregate
Waterfront structures
Rooftop gardens
Structural repairs and rehabilitation
Insulating backfill and insulating road base
Enveloping underground conduits and pipelines for insulation or when in unstable soil conditions
Landscape and elevated plaza fills
Bulkheads & retaining walls
Fill over poor soil and marshlands
Shallow foundations
Landfill leachate drainage systems
LIGHTWEIGHT GEOTECHNICAL FILL
Buildex® lightweight aggregate has many features that make it an ideal lightweight geotechnical fill – for use in helping convert unstable soils into usable:
Half the weight, coupled with a high internal friction angle can reduce vertical and lateral force by more than one-half
• Free draining
• Provide insulation
• Chemically inert
At nearly half the weight of common fills, Buildex® lightweight aggregate provides an ideal lightweight option for backfilling retaining walls, reducing loads over structures, or insulating thermally sensitive elements.
Because natural sand and soil is heavy, structural modifications are frequently required in many exterior project designs. Native soils have silts and clays that may compact and clog filters and drains. Also, natural materials degrade over time, which requires additions to the planting media. Though horticultural products such as vermiculite and perlite are extremely light in weight, they are easily washed away and do not offer adequate anchorage and support for larger plants. This is why Buildex® lightweight aggregate is an ideal solution.
