DELTA-NaturaDRAIN is a high-performance, 3-dimensional drainage composite with three layers. It consists of a dimpled drainage core and two layers of high-strength polypropylene (PP) geotextile.

One geotextile (gray) is heat-bonded to dimples, and the other geotextile (white) is fully adhered to the backside of the drainage core. Provides a smooth surface for the application of a liquid applied waterproofing membrane. The drainage core is made from a special high-density polyethylene (HDPE) that provides high impact and tear resistance and is unaffected by environmental stress cracking. The non-clogging geotextile is fully bonded to the dimpled drainage core, which prevents it from being pushed into the flow channels

  • 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.
