Waterproofing
Overview
We waterproof foundations, retaining walls, plaza decks, balconies, planter boxes, and water
features. The membrane bridges hairline cracks and conforms to complex penetrations and details
that would be nearly impossible with traditional materials.
Key Benefits
Truly Seamless
Crack-Bridging
Elastomeric flexibility
spans movement and
shrinkage cracks.
Fully Bonded
Rapid Schedule
Our Process
Moisture & Substrate Check
We confirm the surface is sound and within moisture limits before starting.
Detailing
Penetrations, cracks, and transitions are reinforced and treated first.
Primer Application
A bonding primer prepares the substrate for the membrane.
Membrane Spray
Seamless elastomeric membrane applied to spec thickness.
Flood/Adhesion Test
We verify integrity before any cover or backfill goes on.
Common Applications
Foundation & below-grade walls
Plaza & parking decks
Balconies & terraces
Planter boxes
Water features & fountains
Elevator pits & sumps
FAQs
Can you waterproof over existing cracks?
Yes — cracks are detailed and reinforced first, and the elastomeric membrane bridges movement.
How soon can I backfill?
In most cases the same day, thanks to fast-cure chemistry. We’ll confirm on-site.
Is it suitable for potable water?
We offer NSF-compliant systems for potable water tanks on request.
