Commercial Waterproofing · Est. 2014
Watertight buildings, written warranties, no surprises.
We're a Scottsdale-based commercial waterproofing and protective coatings contractor serving property managers, GCs, HOAs, and industrial facilities across the Phoenix metro. Roof coatings, foundations, parking decks, and industrial floors — engineered for Arizona conditions, installed by our own crews.
What we do differently
Spec it once. Install it right. Document everything.
Written, tight scopes
We bid against a written scope of work — substrate, prep, named product, mil thickness, warranty target. So the proposal you compare is the work you'll get.
Arizona-specific systems
We only spec systems we've watched perform here. Silicones that handle ponding. Polyurethanes that survive deck loads. Floor systems that take real forklift traffic.
Self-performed crews
100% of our waterproofing, coating, and sealant work is installed by Imperplak employees on payroll, supervised by an OSHA-30 foreman every shift.
Services
A complete commercial waterproofing offering.
Who we work with
Built for the people who own and run commercial buildings.
We don't bid single-family residential. We work with property managers, GCs, HOAs, industrial facility teams, and public-sector owners across Arizona. Our paperwork, insurance limits, and field protocols are built for that world.
Industries we serve
Featured project · 2024
68,000 sq ft of office-park roof restored without a tenant disruption.
A six-building Scottsdale office park had quotes for a full TPO tear-off estimated at $1.4M. We restored the roof in place with a 30-mil silicone system and a 15-year manufacturer NDL warranty, completed across all six buildings in 11 working days.
- 68,000 sq ft, 6 buildings
- GE Enduris 3500 high-solids silicone
- 15-year NDL manufacturer warranty
- Zero tenant disruption · zero callbacks
Said about our crews
The owners and managers we work for.
"Imperplak restored 68,000 sq ft of TPO roof across our office park without disrupting a single tenant. Their daily photo documentation is the best I've seen from any contractor on our vendor list."
"We had a deck failure two days before closing. David's crew was on site within four hours, identified the leak path, and had a permanent repair scope to me by the next morning. Saved the transaction."
"Three other contractors quoted us a tear-off. Imperplak quoted a restoration with a 15-year NDL warranty for less than half. We're four years in and the roof is performing exactly as they said it would."
