Moisture-Free Storage, Guaranteed

Permanent sealing solutions for underground commercial spaces

Underground storage rooms and commercial basements are valuable square footage — but only if they stay dry. Cracks in concrete walls or floors can allow groundwater, vapor, or contaminants to enter, putting equipment, inventory, or infrastructure at risk. We use pressure injection sealing to waterproof these spaces without the need for excavation.

Our sealing services are designed for facilities with critical storage needs — from data centers and mechanical rooms to wine cellars and retail storage. Whether you’re dealing with visible leaks or hidden moisture, we can stop it at the source.

Our Process

Step 1

Interior inspection with moisture mapping

Step 2

Targeted identification of all leak paths

Step 3

Use of expanding polyurethane injection for active leaks

Step 4

Long-term waterproof sealing and optional membrane finishing

Step 5

Clean, odorless process — no digging, no mess
