1. Opinion

It is the opinion of the Canadian Construction Materials Centre (CCMC) that “Superior Walls Xi Precast Concrete Insulated Wall Panels”, when used as a prefabricated foundation wall for housing and small buildings in accordance with the conditions and limitations stated in Section 3 of this Report, complies with the National Building Code 2010:

  • Clause 1.2.1.1.(1)(a), Division A, using the following acceptable solutions from Division B:
    • Article 9.3.1.1. General (concrete)
    • Subsection 9.4.2. Specified Loads
    • Subsection 9.4.3. Deflections
    • Subsection 9.13.2. Dampproofing
    • Subsection 9.13.3. Waterproofing
    • Subsection 9.13.4. Soil Gas Control
    • Subsection 9.14.2. Foundation Drainage
    • Article 9.25.2.1. Thermal Insulation
    • Article 9.25.2.2. Insulation Materials
  • Clause 1.2.1.1.(1)(b), Division A, as an alternative solution that achieves at least the minimum level of performance required by Division B in the areas defined by the objectives and functional statements attributed to the following applicable acceptable solutions:
    • Subsection 9.4.1. Structural Design Requirements and Application Limitations
    • Subsection 9.4.4. Foundation Conditions
    • Subsection 9.15.3. Footings
    • Subsection 9.15.4. Foundation Walls

This opinion is based on CCMC's evaluation of the technical evidence in Section 4 provided by the Report Holder.

2. Description

The product is a prefabricated, insulated precast foundation wall. The foundation walls are formed from 34.4 MPa normal weight concrete containing synthetic fibers. The proposed walls consist of a 44-mm-thick exterior face shell that is monolithically cast with 260-mm-wide top and bottom bond beams and 57-mm x 190‑mm concrete studs at 610 mm on centre (o.c.). The shell is bonded to a 63.5-mm polystyrene insulation on the inside face. Each stud is wrapped with a 25.4-mm-thick expanded polystyrene insulation on three exposed sides and faced with a galvanized steel channel for interior finish fastening. Two 25.4-mm chase openings with 38.1‑mm knockouts are provided in each stud for plumbing and electrical wiring. Wall panels are available in heights of 1219 mm, 2489 mm, 2743 mm and 3048 mm and in various lengths.

3. Conditions and Limitations

CCMC's compliance opinion in Section 1 is bound by the “Superior Walls Xi Precast Concrete Insulated Wall Panels” being used in accordance with the conditions and limitations set out below.

  • The precast foundation walls are for housing and small buildings as directed by Part 9 of Division B of the NBC 2010.
  • Soil type, drainage characteristics of the soil, frost depth and loadbearing capacity must be determined prior to using the precast foundation walls.
  • The precast foundation walls are to be used only in buildings of light-frame construction that are no more than 3 storeys in building height, with a maximum floor-to-floor height of 3 m, and containing only a single dwelling unit.
  • The axial compressive load applied is limited to 8185 kp/m.
  • The design is applicable for seismic zones Sa(0.2) ≤ 1.2.
  • Exterior surfaces of foundation walls below ground level must be dampproofed in accordance with Subsection 9.13.1. of Division B of the NBC 2010.
  • The builder must prepare site conditions in accordance with Superior Walls Builder Guideline Booklet, MAN42-9000.
  • Foundation walls and footings must be installed on stable soils with an allowable bearing pressure of 75 kPa or greater.
  • Minimum footing widths must comply with Table 4.2.2.1 of this Report or comply with Subsection 9.15.3. of Division B of the NBC 2010.
  • Maximum load applied to brick ledge is restricted to 4316 kp/m.
  • Foundation must be well drained in accordance with Subsections 9.14.3. or 9.14.4. of Division B of the NBC 2010.
  • The proposed wall system must be used with floor systems not exceeding loads and spans as directed by the Subsection 9.4.2. of Division B of the NBC 2010.
  • Backfill must be placed in such a way as to avoid damage to the wall and the waterproofing protection.
  • The backfill material with surcharge must not exceed 1602 kg/m2/m.
  • The on-site concrete basement floor must be poured prior to backfilling.
  • The top of the foundation wall must be supported by the first floor prior to backfilling.
  • Where hydrostatic pressure exists, waterproofing must be provided in accordance with Subsection 9.13.3. of Division B of the NBC 2010.
  • Installation of the product must be completed by a person certified by Superior Walls of America.
