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 no longer flow due to 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.

  • Before any digging gets underway, The City Wide Group ensures all utility services are informed and the dig site is clearly marked.

  • We first reveal the foundation’s walls and base, giving them a good clean to guarantee that the new concrete will bond well.

  • To deal with any cracks or openings in the foundation, we fill them with a specific type of cement before applying a fresh concrete layer over the entire area.

  • We then secure the foundation with a RUBBER BITUTHANE MEMBRANE for waterproofing, covering both the wall and its base.

  • Additionally, we attach a DELTA MS plastic mat along the foundation wall down to the base, aiding in water drainage.

  • New weeping tiles are installed to divert water from the foundation, surrounded by clean ¾” gravel to ensure proper drainage.

  • The dug-out soil is then replaced and compacted firmly to avoid any future ground movement.
