| Chemical Foam Grouting |
|
| Generally used for stopping running water or controlling intermittent moisture, chemical foams are available in hydrophobic or hydrophilic versions. They are water-activated, 100% solids, polyurethane, expanding foam for permanent repairs. These products are also available in rigid or flexible formulations to be used in nonmoving cracks or moving joints. This procedure is performed from the negative-side, injecting foam through the structure creating a positive-side waterproofing, even 10 stories under ground.
