Product information

Product name

Superior Walls Xi Precast Concrete Insulated Wall Panels

Product description

The product is a prefabricated, insulated precast foundation wall. The foundation walls are formed from 34.4 MPa normal weight concrete containing synthetic fibres. The walls consist of a 44.5-mm-thick exterior face shell that is monolithically cast with 260-mm-wide top and bottom bond beams and 57-mm × 190-mm concrete studs at 610 mm on centre (o.c.). The shell is bonded to 63.5-mm- or 127-mm-thick polystyrene insulation on the inside face. Each stud is wrapped with 25.4-mm-thick expanded polystyrene insulation on 3 exposed sides and faced with a galvanized steel channel for interior finish fastening. Two chase openings are provided in each stud for plumbing and electrical wiring. Wall panels are available in heights of 1 219 mm, 2 489 mm, 2 743 mm and 3 048 mm, and in various lengths.

  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.

  • The precast foundation walls are for housing and small buildings as directed by Part 9, Housing and Small Buildings, 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 three 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 109.453 kN/m.
  • The design is applicable for seismic zones with Sa(0.2) ≤ 1.2.
  • Exterior surfaces of foundation walls below ground level must be dampproofed in accordance with Subsection 9.13.1., General (Dampproofing, Waterproofing and Soil Gas Control), of Division B of the NBC 2010.
  • The builder must prepare site conditions in accordance with Superior Walls Builder Guideline Booklet, MAN42-9027.
  • 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.
  • The maximum load applied to a brick ledge is restricted to 42.320 kN/m.
  • The foundation must be well drained in accordance with Subsections 9.14.3., Drainage Tile and Pipe, or 9.14.4., Granular Drainage Layer, 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 1 602 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, Ltd.
