Commercial Waterproofing & Building Envelope · Tri-State
Below-grade waterproofing, chemical grout injection, building envelope, and roofing membranes. Foundation to Roof. Projects up to 150,000 SF. Authorized installer for the systems your spec already calls for.
SealProof supports general contractors, owners, property managers, and design professionals seeking a single accountable subcontractor for waterproofing, roofing membranes, traffic coatings, air barriers, and specialty leak remediation.
From a leaky elevator pit to a high-rise foundation — and everything in between.
SealProof handles the full envelope — from waterproofing under the foundation slab to the parapet flashing on the roof. One sub, one contract, one COI to chase down instead of three.

When the spec calls for Sika, GCP, Tremco, Carlisle, Hydrotech, Soprema, or any system below, the authorization letter is already on file — warranty stays valid, the rep shows up to inspect, the bid moves.
From foundation walls to roof transitions, we help general contractors, owners, and design teams reduce scope gaps, protect warranties, and keep water out of the building. Send the drawings, the schedule, or just call — we'll tell you straight whether we're the right sub.
