There are three basic approaches for sealing water leaks at concrete wall and floor defects. These approaches include:

1. Backside Injection; whereby a grout material is deposited behind the wall or floor crack/joint and/or into the earth backfill. The grout material solidifies the soil and plugs the point of origin of leaking water.

2. Internal or Interception Injection; whereby a grout material is deposited into the internal concrete crack/joint. The crack or joint is internally intercepted and grout fills the crack/joint from internal to external face.

3. Surface Seal; whereby a grout, mortar, sealant, or composite material is surface applied over the leaking crack/joint; or said leaking crack/joint is partially routed-out and plugged with a water impedance material.
