  • 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.

  • After the work is finished, we thoroughly clean the site of any construction debris.

  • To wrap up, we repair and reinstate any outdoor spaces and landscaping that were affected by our work.
