It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as as a load transferring backfill in the void space between the ground and the wood posts of fences and patio decks in accordance with the conditions and limitations stated in this evaluation, complies with the following code:
National Building Code of Canada 2015
|ID||Code provision||Solution type|
The above opinion(s) is/are based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.
Fast 2K™ Deck Post Anchor
The products are two-part polyurethane foams for use as load transferring backfill. One component is an isocyanate polymer and the second component is a polyol. They are combined in a specific ratio mixture to produce the foam that is intended to be used as backfill. The products are intended for use in the void space between the ground and the wood posts in the installation of fences, patio decks, porches, verandas, barns, sheds, and other similar applications (see Figure 1 below).
This evaluation is valid only for products produced at the following plant:

Conditions and limitations
The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.
- For applications beyond the scope of this Report, i.e., foundations for decks and other accessible exterior platforms more than 1 storey and 55 m2 in area, where the distance from finished ground to the underside of the joists is more than 600 mm and the structure supports a roof or is attached to another structure, or where a constant hydrostatic pressure is expected on the foam, the design must be carried out by a registered professional engineer in accordance with the applicable Codes, including the NBC 2015.
- The installation of the products requires that the excavation of the hole must be started below the frost line. The required diameter of the hole to transfer the load from the post to the surrounding ground will depend on the expected load carrying capacity of the structure to be supported. The allowable bearing pressures of the ground (soil and rock) are referenced in Table 18.104.22.168. of Division B of the NBC 2015.
- In areas known to be infested by termites, the requirements in Article 22.214.171.124., Termite and Decay Protection, Article 126.96.36.199., Removal of Topsoil and Organic Matter, and Article 188.8.131.52., Support of Floor Joists, of Division B of the NBC 2015 must apply.
- The products should not come in contact with gasoline or other chemicals that have not been evaluated. For a list of acceptable chemical exposures, please consult the manufacturer.
- The long-term performance of the products will depend on local conditions such as the soil type, hydrology and mineralogy of the site, and the presence of microorganisms in the soil among other issues.
- The products must be installed according to the manufacturer’s installation manual dated January 2017, which can be accessed at www.chemque.com.
This evaluation is based on demonstrated conformance with the following criteria:

Results of testing the products in-situTo assess the foam in the in-situ conditions, 24 wood posts were installed at our NRC field exposure site in September 2013. Twelve were removed in 2014, nine in 2015, and the final three were removed in November 2016. The posts were removed from the ground with a forklift and heavy chain. During the removal of the posts from the ground in 2014, 2015 and 2016, the posts broke before failure of the foam was observed. Field pullout and lateral load tests on the posts indicated that the products exhibited strong adhesion to the posts and formed strong anchors in the soil. In addition, the foam itself was found to be in satisfactory condition and free of any signs of degradation on the last three posts even after being in the ground for three years.
