Steve St. Arnaud was asked to consult regarding a moisture problem in 8-yr old home.


  • Water droplets in corners of slab-on-grade, condensation on windows and a moldy smell
  • Moisture seeping under slab on-grade floor due to lack of weeping tile and lack of sufficient foundation across back wall
  • New Home Warranty Program contacted to detail scope of work for warranty claim.


  • Hand excavating 14 metres of material under the slab on-grade (3.5 ft x 24 ft x 8 ft) 
  • Pouring structural concrete wall through the middles of the slab
  • Filling the cavity with low density concrete 
  • Installing new weeping tile

Project completed in 5 weeks during winter
