INJECTION WATERPROOFING

Spec 7 Group can provide "no dig repair", Targeted and Blindside Injection Waterproofing by using Hydrophilic and Hydrophobic Grouts.

Hydrophilic Grout absorbs and retains water molecules allowing the grout to expand into and replace water that may be present in finer cracks and throughout a wall that a main crack occupies. 

Hydrophobic Grout repels water and resists moving toward wet areas, oftentimes used to stabilize soil.

Common places we use Injection Waterproofing:

  • Elevator Pits

  • Tunnels

  • Previously failed waterproofing systems

Find us a leak we can't fix and we will do it for free.
