Basement Waterproofing

Exterior Basement Waterproofing

Waterproofing your basement becomes necessary when the foundation begins to leak or let moisture through, allowing it to deteriorate.

Foundations leak for various reasons, such as; a congested weeping tile system, where the weeping tile can longer flow due a blockage of debris, soils or tree roots. Horizontal or vertical cracks in the foundation, or separation of blocks, voids where the foundation and footing meet, allow water to enter into the basement.

Many foundations were never waterproofed properly during the construction process, particularly older buildings.

  • Prior to excavation, all utilities are contacted by us and a stake out is commenced.
  • Once the foundation walls and footing is exposed, the wall is washed down to allow a proper bond for the concrete parge
  • All cracks, voids in the foundation is compacted with hydraulic cement and the entire wall surface is given a layer of concrete parging
  • A RUBBER BITUTHANE MEMBRANE is applied to the foundation wall covering down, over the footing
  • A DELTA MS, plastic drainage mat is applied to the foundation wall, down to the footing level
  • New weeping tile is installed and connected to the appropriate drainage point and surrounded in clean ¾” gravel
  • All soil is backfilled and compacted to prevent future settlement
  • All debris are removed from the site
  • Any finished surface material is re-installed, such as concrete, asphalt, interlocking stone etc.
