Nomaflex Installations

Nomaflex expansion joint filler has been installed in commercial, residential and DOT applications throughout the US since its introduction in 2015.

Its primary purpose is for use as an expansion joint filler for concrete sidewalks, driveways, curb & gutters, medians, roadways, concrete ditches, retaining walls and other concrete structures. It can be used as a form, especially where curves or radii are required. It can also be used with or without joint sealant.

This gallery of installations supports the physical property testing as completed through the national AASHTO APEL program. The APEL data substantiates the benefits of using Nomaflex as an alternative to the currently specified materials. View ASTM D8139, the new standard specification for semi-rigid, closed-cell polypropylene foam.

Used as a Form

In December 2015, Nomaflex 6″ wide plank was used as a form for a college fountain project in Durham, NC.  Nomaflex bends easily and will not crack or break.  After the concrete was poured, the contractor easily removed the Nomaflex form and can re-use the product on future jobs.

Highway / Bridge Retaining Walls

On a major cast-in-place highway/bridge retaining wall project in Downtown Columbus, OH, contractors replaced traditional asphalt-impregnated fiberboard with Nomaflex® Sheet to eliminate staining and leaching issues.

Unlike fiberboard, Nomaflex contains no asphalt binders, so it won’t stain decorative walls. It’s lightweight, easy to cut with a utility knife, and fast to install using standard concrete nails and washers. Nomaflex was used as expansion joint filler between vertical walls and footings, drainage ditches, and across flatwork.

After the concrete pour, tooling was smooth and clean, and joint lines remained tight—with no spalling, gaps, or staining. Contractors saved time and money by avoiding costly stain removal and repairs.

Municipal Sidewalk Project

In December 2016, Nomaflex® Sheet was installed as an expansion joint filler on a municipal sidewalk project in Tucson, AZ—with no fasteners required. During the concrete pour, Nomaflex stayed securely in place without floating or extruding.

Post-pour, tooling was simple and the joints had a clean, professional finish. Sealant was not applied, leaving Nomaflex exposed to the elements. After over two years of service, Nomaflex shows no degradation, extrusion, or spalling, and remains tightly in place—preventing debris infiltration and maintaining joint integrity.

DOT Project

Nomaflex was used as both expansion joint filler and a concrete form on a Mississippi community college sidewalk, curb and gutter project. This project was completed in March 2017 and required nearly 1000 linear feet of Nomaflex expansion joint filler. As of today, Nomaflex is still in place and shows no signs of degradation.

"You have a winner with this product. It's easy to work with, and after a couple of weeks, the concrete naturally releases from the top edge—leaving a clean finish. With asphalt board, we had to scrape off the overpour. With Nomaflex®, we just sweep it clean!"

Commercial Installation

Nomaflex was installed in May 2015 in this North Carolina commercial building.  It was used as both expansion joint filler and isolation joint filler on the curb and gutter, between pedestrian walkway slabs and between the slab and building.  Before the concrete pour, Nomaflex was held in place with standard nails and pins. The contractors were pleased that Nomaflex could easily bend around corners without breaking.

After 4 years of service, Nomaflex is still in place and shows no signs of degradation – unlike the adjacent asphalt impregnated fiberboard shown in the gallery below.
