Learn the Advantages of Hollowcore

There are many advantages to using prestressed hollowcore planks and precast concrete stair systems. We can safely and quickly install your hollowcore planks with no forming, shoring, or restoring. Hollowcore allows for a faster installation. When we arrive at your construction site, hollowcore planks are ready to be installed. 

A Cost-Effective Concrete Option

The ease of utilizing hollowcore means fewer man-hours to install decks and minimal onsite rebar fabrication. The plant-controlled production of hollowcore assures better quality and the overall consistency of the concrete itself. Hollowcore requires lower maintenance and has saved owners millions in insurance premiums. 

A Truly Versatile Material

  • Block, steel, and / or concrete framing bearing

  • Cantilevers and long spans

  • Steel hangers

Lightweight Design Capable of Heavy Loading

Hollowcore is a lightweight structure that can handle heavy loads. Hollowcore is typically used in low and mid-rise buildings. However, it has been used in a 30 story hotels in Las Vegas.

Fire-Resistant and Soundproof

Our hollowcore slabs have an inherent 1-hour fire rating. Available fire rating up to 4 hours through special design and lightweight aggregates. The dense composition gives the material a high sound transmission class rating as well.
