Nordic Void ThermaGuard TG-250

Ask a Question

Our Nordic Void ThermaGuard TG-250 is the next generation of void form. Building upon the characteristics of Norseman’s original Nordic Void Form, TG-250 offers improved thermal insulation, resiliency and weight bearing capacity. This engineered structural load bearing, resilient void form, has been designed to protect foundations from damage due to frost heave and soil swell. Compared to traditional void materials, Norseman’s TG-250 will not biodegrade or collapse under the foundation. As the ground pressure subsides, it will recover most of its thickness and prevent the void space from filling with unwanted materials – protecting the foundation year after year.

    Product Benefits

    • Resists significant degradation from hydrocarbons including bitumen laden soils, crude oil and diesel fuel. 
    • Chemical and water resistant.
    • Available in a multitude of thicknesses.
    • Performs consistently over a wide range of temperatures.
    • Lightweight; installs easily and quickly.
    • Does not require protective poly or surface protection such as plywood or OSB; can be walked on and concrete can be poured directly onto it.
    • Reusable and completely recyclable.

     

    Benefits of Nordic Void ThermaGuard VS. Standard Nordic Void

    • Acts as an elastomeric insulator to dissipate the up-lift forces caused by multiple frost heave and soil swell cycles. Without this protection, the transfer of force directly to pile caps, foundations, grade beams and other poured concrete forms could result in structural damage.
    • Has a 40% improvement in its thermal insulation value when compared to our original Nordic Void products. When installed as an insulating flank around the foundation, TG-250 helps prevent frost from migrating under the pile cap/slab, to better reduce heave.
    • More resilient with a 25% improvement in resistance to creep (i.e.: permanent loss of thickness under constant static compressive load). Testing involving multiple stress/strain cycles also shows improved resiliency, meaning that TG-250 will perform year after year.
    • Nordic Void TG-250 offers a 30% increase in load bearing capacity, allowing for higher concrete pour weights and improved.

    As part of our commitment to helping our customers make informed decisions, we offer a Lunch and Learn program about our Nordic Void solutions. The Lunch and Learn program is available to organizations, in Canada and selected US states, involved with engineering, design, specification and construction of structural foundations for infrastructure, industrial and commercial applications.  

     

    Norseman will come to your place of work to present comprehensive information about Nordic Void to your team and answer any questions you might have. We will even supply the lunch! The presentation will educate your team on the benefits of Nordic Void and provide detailed information on calculations and design.

     

    Presentation Overview:

     

    • Why use a void material? An overview of the effects of reactive/expansive (swelling) soils and frost heave on foundations
    • The benefits and drawback of different types of void form used historically and today
    • Characteristics of an optimized void form like Nordic Void
    • Compressive stress, compressive sets and resiliency. What they are, why they are important and how can they impact your designs
    • Overview of the Nordic Void family of products including ThermaGuard 250 and the improved R-Value and resiliency.
    • Past projects where Nordic Void has been successfully used
    • A walk through of a sample application and calculation using ThermaGuard 250

     

    Who Should Attend?

     

    • Civil/ Structural engineers
    • Civil/ Structural designers
    • Engineers practicing industrial foundation design (e.g.: Pile/Pile Cap)
