Crack Seal, Lyndeborough, NH

Before and after look at a foundation wall crack. The crack was behind a finished wall in the home's basement, so drywall needed to be removed in order to access the crack. The foundation crack was sealed with a polyurethane injection, a foam material that quickly expands within the crack and effectively seals it all the way through. On the surface of the crack, an waterproof epoxy, NexusPro, is applied to further protect against seeping water.
