EPS Voids – Void Formers

EPS Voids in construction field.

Expanded polystyrene (EPS) has numerous construction applications due to its outstanding quality and relatively low costs. From serving as semi-disposable formwork to insulating buildings, there are few things this thermoplastic polymer can’t do. One of the more common issues plaguing the construction industry is the immense dead weight of concrete. To help reduce the burden of excess concrete, construction sites are turning to EPS voids. Here’s what you need to know about them.

EPS Void Formers – An Efficient Construction Solution


  • > Durable
  • > Lightweight
  • > Ease of handling
  • > High thermal insulation properties
  • > Low thermal conductivity
  • > High compressive strength
  • > Long term retained R-values
  • > Low moisture and water absorption
  • > Fire retardant
  • > Environmentally friendly


  • > Void Filling
  • > Bridges
  • > Roads / Highways
  • > Landscaping

One of the many construction challenges is to reduce the weight of concrete on the soil beneath it. EPS void formers replace some of the concrete in structures, allowing for a faster project construction time as well as reduced costs. Expanded polystyrene is significantly cheaper than pouring tonnes of concrete for a large civil engineering project.

Besides reducing project construction time and thus expediting the construction process, void formers will decrease the concrete volume while increasing the strength of the structure.

EPS Is Easy to Handle and Affordable

How can EPS reduce the construction time and costs so drastically? There are a couple of answers to that question.

First of all, EPS is a lightweight material that’s easy to handle and doesn’t require the use of special equipment or cranes. You’ll be able to move the construction void filler around the site without any difficulties and install it with ease. It also helps that it’s easy to stack, saving precious space.

Secondly, EPS is one of the most affordable versatile materials you can get your hands on. Both EPS’ cost and its lightness make it a cost-effective solution for a variety of construction projects

Void Filling with EPS

Sometimes, projects require only temporary void filling that can later be easily removed. Polystyrene void fillers serve that purpose perfectly.

EPS is extremely easy to cut, so you can shape it any way you like. That’s why it’s so common to see EPS cylinders filling void spaces in bridges or other large construction projects. Once it’s time to remove the cylinder to create a service tunnel and install utility piping, you’ll be able to get EPS voids out of the way without effort.

Other void fill applications include highways, roads, and landscaping projects, but also several others.

The Superior Material

EPS is better than other void fillers not just because it’s cost-effective. It stands out as a superior material in every possible way due to a number of its characteristics:

  • High compressive strength. The high compressive strengths of EPS void fillers are what makes it possible for this material to replace concrete.
  • Water absorption. EPS boasts high water resistance making it quite suited to outdoor applications.
  • Fire retardation. We treat our EPS with fire retardants during the manufacturing process to make it a safe filling solution.
  • Durability. EPS retains its qualities over long periods of time, so consider it an investment into the future.
  • On top of all that, EPS contains zero toxic chemicals and it is completely eco-friendly. It contributes to your project’s sustainability.
