Modular Construction For Easy On-Site Installation

Alternative to conventional cast-in-place, pre-cast and masonry methods of core construction.

READY TO INSTALL CORES

Our cores are pre-fabricated at the factory, custom engineered to your specifications, so that you can begin setting steel right way.

UPPER LEVEL ACCESS

Pre-fabricated stairs shipped in cores enable building trades early and safe access to upper levels of structure.

SAVE TIME

Cores can be constructed simultaneously, reducing jobsite schedule by weeks or months on most building projects.

Rapid, Simplified Erection Process

CorTek’s modular construction and easy on-site installation allows for our factory-built, ready-to-set cores to be simultaneously stacked for up to several levels, saving time, energy and money.

Modular Construction

  • Factory-built cores
  • Shipped ready to install
  • Minimize costly site time
  • Stacks like building blocks
  • Up to 12-story capability
  • Several cores can be constructed simultaneously
  • After concrete placement, structurally equivalent to 8″ – 12″ CIP concrete wall

Easy On-Site Installation

  • Stair rails ship inside cores
  • Begin setting steel right away
  • Concrete placed within walls onsite
  • No waiting on core curing – Framing does not wait for cores
  • Provides safer, earlier, and more efficient builder trade access to floors
  • Reduction of poor fit-up and coordination programs among trades

Factory-Built Features Tailored To Your Project

This innovative construction approach incorporates the higher level of quality and efficiency provided by a specialized factory manufacturing environment, which reduces jobsite labor resource and schedule needs. Also a higher level of jobsite safety is provided through the elimination of the fall hazards inherent in vertical concrete formwork construction methods.

Factory-Built, High Tolerance, All-Steel Construction

Load-bearing form system constructed with vertical and horizontal structural elements that are designed to support construction loads, and allow modularization of the form system. Structurally equivalent to 8″ – 12″ CIP concrete wall.

Level the Core with a Turn of a Nut

This adjustable screw allows you to ensure the first core is level before pouring concrete, saving time and money.

Preinstalled Connections For Floor And Roof Framing

Necessary connections for framing each level are pre-installed to save time. Each stack provides the tools to access the upper floor, start construction and pour concrete as you go. Modules go up with floor framing and do not require stripping. Cores are compatible with steel, concrete and wood framing.

Safer, Earlier And More Efficient Trade Access To Floors

Provides safer, earlier, and more efficient builder trade access to floors, and enhances flexibility of construction sequence scheduling.

Materials Are Pre-Installed In The Factory

Cores With Stairs

Stairs arrive pre-fabricated inside each core, providing early trade access to the building floors. Hand rails come shipped with each core.

Elevator Shafts

Cores are available without the stair system for rapid construction of elevator shafts.

Galvanized, Corrugated Steel Allows For Multiple Finish Options

Galvanized steel surface can be left exposed, painted, or covered with almost any architectural surface material.

Galvanized Corrugated steel

Pre-treated galvanized corrugated steel can be left as is.

Covered

Drywall, laminate, etc. can easily be affixed to the corrugated steel ridges.

Painted

The pre-treated galvanized steel will accept any standard wall finish.
