The Next Generation of Underground Enclosures

Lighter, stronger and well...more durable. NewBasis introduces the next generation of composite material for infrastructure products: Monolith®.

This new patented material has unmatched strength compared to traditional enclosures. Combined with a flared wall design and tested at T22, it is a first in the industry.

  • Our new lightweight material is 19% lighter than our traditional polymer concrete product.
  • Monolith® products are certified to Tier 22, and are 10% stronger than our traditional polymer (PCA) material.
  • Our patented design offers a smooth outside surface, eliminating fiber-woven skin irritation.
  • Offers a new removable nut box design which extends the usable life of the box.
  • U.S. Patent No. 11,931,930
  • Flared construction offers many benefits for the underground enclosure environment:
    • Wall design will allow up to 10% more interior volume than traditional designs.
    • Flared design will allow for easier nesting, reducing freight costs on average by 40%.
    • Flare wall design prevents frost heave and prevents unnecessary "pop-out" movement.
  • Available with an optional SMC cover.
