Toplite Foundation benefits

  • Speed of construction - compared to cavity work, construction time is improved and the Foundation wall becomes stable soon after laying, allowing the early start of above ground work.
  • Save money - replaces the inner and outer leaf, wall ties and concrete cavity fill associated with conventional cavity walls.
  • Excellent performance - good resistance to freeze/thaw conditions and contributes to perimeter edge insulation.
  • Suitable for use in sulfate conditions up to DS-3
