Termite Resistance

  • No untreated wood left in soil or stored near structure
  • Moisture managed construction (See Moisture Control section)
  • Professional soil treatment under foundation
  • Termite barriers at hidden pathways
  • Best: no untreated structural wood or vulnerable insulation
  • Borate-treated wall/roof framing , cellulose insulation, foams
  • Pressure-treated (not borate) or composite wood decking
  • Masonry, concrete or steel construction

Slab foundation:

  • Monolithic poured slab
  • Slab specifications to minimize cracking
  • Steel mesh epoxied pipe collars within slab
  • Consider treatment of control joints and cracks
  • No wood forms, stakes, etc. left in ground

Raised foundations:

  • No hollow concrete blocks below grade
  • Hollow block foundation walls capped with concrete
  • Piers are solid, resistant material
  • Termite shields between foundation and framing to force termite exposure
  • Floor joists >18 in. above ground

All foundations:

  • No vulnerable foam insulation under ground (below grade)
  • Min. 8-in. clearance between siding and finished grade
  • Min. 6-in. clearance between wooden steps and soil

Foundations detailed for ease of inspection and detection

  • Porches, terraces not filled with soil
  • Porch supports separated from house min. 2 in.
