Internal Drainage

Solve Basement Water Problems with Internal Drainage from Woodstock’s Ltd.

An internal breakout, sometimes called an interior weeping tile, interior French drain, or interior drain system is an interior water control system. When designed and installed correctly, this is an ideal solution that can offer the homeowner a permanent solution to water infiltration through basement walls as well as relieving ground water pressure. At, we offer this internal drainage service to Woodstock, London, and other areas throughout Ontario.

Internal Drainage
  • Excellent choice where exterior access is limited by driveways, decks, landscaping, etc.
  • Typically less expensive than exterior excavation with equal moisture control effectiveness
  • Waterproofing solution for all types of foundations including poured concrete, concrete block, stone, brick and fieldstone
  • The internal breakout is a much more effective solution than drainage tile laid atop or at the edge of the basement floor
