It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a concrete pier 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|
Ontario Building Code
Ruling No. 22-02-371 (13309-R) authorizing the use of this product in Ontario, subject to the terms and conditions contained in the Ruling, was made by the Minister of Municipal Affairs and Housing on 2022-10-05 pursuant to s.29 of the Building Code Act, 1992 (see Ruling for terms and conditions). This Ruling is subject to periodic revisions and updates.
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.
The Footing Tube
The product is a concrete pier form that is made of plastic and manufactured from recycled, linear low-density polyethylene with an ultravio- let stabilizer. The tube is tapered to provide stackability during shipping and storage, and has a resistance to frost penetration and water. The concrete pier form is available in three sizes: 152 mm (6 in.), 203 mm (8 in.) and 254 mm to 305 mm (10 in. to 12 in.). A base pier measuring 546 mm (21 in.) (FTB30) is also available, which can be used under the 203-mm (8 in.) or 254-mm to 305-mm (10 in. to 12 in.) tube to accommodate additional loadbearing areas.
The product is identified with height scribe lines to indicate the level of concrete required to fill the tube and determine backfill height. The tube can also be cut to the desired height using the scribe lines as a guide.
The safety top on the tube keeps out water, dirt from backfilling, and other debris that can be present on-site during construction.
The table below provides specific dimensions for the 152-mm, 203-mm and 254-mm to 305-mm tubes and the 546-mm FTB30 base pier. The FT-B30 base pier is not mechanically connected to the tubes, which makes it easier to adjust before leveling.

- The product may be used as a casting product for concrete piers for applications such as decks, porches, fence posts, one-storey cottages and additions, lampposts, pole barns and point load beams.
- In cases where the product is used in seismic zones as defined in Sentence 184.108.40.206.(3), Foundation Provisions, of Division B of the NBC 2015, unreinforced products (tubes) will not be adequate. Proper seismic designs must be carried out by a registered professional engineer in accordance with the applicable codes, including the NBC 2015.
- The allowable bearing pressures and loads for the product are specified in the table above. For applications beyond the scope of this Table, consult a registered professional engineer in accordance with the applicable codes, including the NBC 2015.
- The concrete shall be designed, mixed, placed, cured and tested in accordance with CAN/CSA-A438-00, “Concrete Construction for Housing and Small Buildings,” and shall comply with Subsection 9.3.1., Concrete, of Division B of the NBC 2015. The excavation hole must be backfilled according to the suggested depths before pouring the concrete.
