Product Spotlight: Polymer Concrete / Fiberglass Reinforced Polymer Enclosures

Written By Grace Matthews

As SIGMA moves closer to becoming your full-service enclosure resource, we are pleased to spotlight our new offering of MADE IN USA Polymer Concrete / FRP Enclosures. 

These boxes are widely used across North America, and are ideal for locations with: 

  • Aggressive soils 

  • Temperature extremes 

  • Freeze-thaw cycles 

  • High load requirements  

  • Larger metering/transmission installs 

Because polymer concrete is dimensionally stable and highly resistant to moisture and chemicals, it provides reliable protection for increasingly sophisticated underground equipment. The material is ideal for use in next-generation metering technologies including: 

  • Advanced Metering Infrastructure (AMI) 

  • Smart water meters 

  • Leak detection sensors 

  • Pressure monitoring equipment 

  • Telecommunications components within utility corridors 

Benefits include: 

  • No reinforcing steel which will rust 

  • High dimensional stability 

  • Resistance to degradation from corrosion, freeze-thaw damage, and other environmental factors 

  • Lighter, high-strength aggregate formulations 

  • Eco-friendly due to greater use of recycled aggregates and lower-emission resin systems 

The growing prevalence of polymer concrete meter boxes reflects the water distribution industry's shift from simply containing infrastructure to protecting it with durable, engineered materials that minimize maintenance and maximize service life over decades.  SIGMA is a proud manufacturer of this innovative product; contact your regional office or Territory Sales Manager to learn more.
