ELASTOPOR LF Slab Jacking Process

elastopor setp1.PNG

Step 1: A small 5/8" hole is drilled into the concrete.

elastopor step2.PNG

Step 2: Polyurethane foam is injected through the holes.

elastopor step3.PNG

Step 3: Liquid polyurethane reacts to become a foam expanding 20x its liquid volume.

Step 4: Foam expands and fills in all the gaps in the soil.

Void Fill

ELASTOPOR VF  Void Fill Systems

Void fill systems are used for filling large voids/spaces fast. Safety challenges like sink holes, mine closures, culverts, etc. can be addressed quickly. ELASTOPOR VF systems are designed for low exotherm and allows for very fast fill of large spaces. Pour system has excellent flow for hard-to-access areas.

Type System Name Density (lb/ft3) Feature Applications
Void Fill Foam ELASTOPOR VF 2250 2 Pour system Large voids, high volume fills
  ELASTOPOR VF 2260 2 Spray system Large voids, high volume fills

Soil Stabilization

ELASTOPOR® GS Polyurethane Soil Stabilizer

ELASTOPOR GS enhances the physical properties of loose or weak soils. Stabilization can improve the shear strength, as well as control the shrink-swell properties of a soil for higher load bearing capacity.


Product Highlights

  • Higher resistance values
  • Reduction in plasticity
  • Lower permeability
  • Reduction of pavement thickness
  • Cost effective

Elastotite® ROCK GLUE Resilient Erosion Control

Effective Erosion Protection and Shoreline Stabilization.

Resilient and durable, ROCK GLUE is a highly effective solution for erosion control and shoreline protection. ROCK GLUE is an open-pored revetment solution that maintains structural integrity and can be used in a variety of applications including shorelines, rivers, drainage channels, and other embarkments.

ROCK GLUE offers significant design flexibility for integration into natural landscapes. The monolithic, porous structure easily conforms into various shapes and promotes natural re-vegetation.  


Product Highlights

  • Porous and water-permeable
  • Strong and resistant to weathering
  • Reduces wave run-up
  • Lower cost for construction and maintenance
  • Seamless integration into environment
  • Restores flora and fauna; protecting neighboring habitats
