Question 1

How does Nordic Void™ protect foundations from frost heave?

Accepted Answer

Nordic Void™ Form is essentially the foundation of the foundation. The foam sits right beneath the concrete slab and acts as a protective barrier against soil expansion or contraction due to moisture or frost-susceptible soil. When there’s freezing in the soil (common in colder climates) or a potential for high-moisture swell (common in climates with a lot of rainfall), the soil wants to expand upward against the foundation. Nordic Void™ resists the upward stresses caused by expansion and keeps the foundation intact, preventing cracking or other damage to the concrete slab. On the other hand, when soil thaws from winter weather or dries from lack of rainfall, the Nordic Void™ helps reduce the counteracting effect of soil contraction, serving as a buffer layer to prevent shifting soils and keep the foundation solid.

Question 2

Does Nordic Void™ require plywood or protective decking?

Accepted Answer

One of the prime advantages of Nordic Void™ is that no top decking is required, which includes plywood or other protective covers. It serves as the base on which your concrete is to be poured. You save time and money with Nordic Void™, as it's designed from structural, load-bearing, closed-cell polyethylene foam.

Question 3

What sizes and thicknesses are available?

Accepted Answer

Nordic Void™ typically comes in sheets that are 48” wide by 108” long in the 100 and 200 grades. The 400 grade comes slightly thinner at 14” wide and 108” long. Thicknesses range incrementally from 2” to 12” thick in the 100 and 200 grades, whereas the 400 grade comes in thickness incrementally from 2” to 8”. You can also bond individual planks together to achieve the desired thickness and shape for your needs with Nordic Void™.

Question 4

Where is Nordic Void™ typically used?

Accepted Answer

Nordic Void™ is used in foundation construction before concrete is poured. It’s very reliable in this context as it won’t biodegrade or collapse under foundation weight over time. It also protects foundations from frost heave and soil swell. Its insulative properties prevent thermal transfer. It is resistant to moisture, insects, vermin, and mold.

Question 5

Which areas are Nordic Void™ Foam primarily needed?

Accepted Answer

Nordic Void™ Foam is ideal for areas where the soil is seasonally frozen or in the “Discontinuous Permafrost Zone,” as well as for areas where high soil swelling is possible. This encompasses a lot of territory in Canada and the US, stretching up to Alaska and the Territories, and over to western Ontario and Quebec.

Question 6

Does the Nordic Void™ Foam need a base layer or barrier to work effectively?

Accepted Answer

No, the Nordic Void™ Foam acts as a compressive barrier between the soil and the concrete foundation and is non-biodegradable and resistant to hydrocarbons. This means that, with seasonal changes in the soil, the Nordic Void™ compresses and rebounds to preserve the integrity of the concrete foundation without breaking down over time and allowing shifting soil and moisture to heave the concrete slab.
