Product information

Product name

The Footing Tube

Product description

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.

Side elevation detail drawing of the FTB30 base pier with labels coordinating to the dimensions listed in the table below. — Figure 2. FTB30 base pier details

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.

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

complying with the applicable acceptable solutions in Division B, or
using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.
