Most new homes are built with “Damp-proofing”—a thin coat of tar that stops vapor but cannot bridge a crack. Once the house settles, the tar snaps, and water enters. At Basement Expert, we use Elastomeric Liquid Membranes. This high-end material is flexible and “stretches” if the wall develops a minor hairline crack, maintaining a seamless, rubberized seal. It is an “Engineering-Grade” solution that actually keeps water out under pressure, unlike cheap tar coatings.
