Below Grade Waterproofing
Membranes and drainage on foundation walls, footings, elevator pits and planters, installed before backfill so groundwater never reaches the basement or the parking levels.
Building envelope solutions
What we install
Six systems, one envelope. Below grade to roof line, on residential, commercial and multi family properties.
The whole envelope
Six sides, one job.
A building keeps water out the way a jacket does, as one continuous skin. Break it anywhere and the water travels until it finds somewhere to show up, which is rarely where it got in.
That is why we scope a roof, a balcony deck, a below grade wall and the air barrier behind the cladding as parts of the same system rather than as four separate trades.

01 — Zone 
Below grade
Everything under the finished grade line, where water sits under pressure and there is no second chance once the backfill goes in.
02 — Zone 
The walls
The vertical envelope, from the sheathing outward. Air, water and building movement all have to be handled in the same assembly.
Above Grade Waterproofing
The parts of the envelope you can see: parapets, planters and balcony to wall transitions, plus the sheet and fluid applied air and weather barriers that run behind the cladding.
Expansion Joints
Joint systems that let a building move without tearing the waterproofing, from sealant joints in a wall to engineered joint covers across a garage deck.
03 — Zone 
Decks and floors
Horizontal surfaces take the weather and the traffic at the same time, which is why they are usually the first thing to fail.
Deck/Traffic Coating
Waterproof deck systems for balconies, walkways and podium decks, applied over plywood or concrete, and traffic bearing membranes for parking structures, ramps and plaza decks that take tire wear and turning loads without splitting at the joints.
Epoxy Coatings
Epoxy floor systems for garages, mechanical rooms and back of house areas, laid over prepared concrete for a hard surface that cleans down easily.
04 — Zone 
The substrate
None of the above holds over concrete that is coming apart, so the repair comes first.
Concrete Restoration
Repair of spalled, cracked and delaminated concrete, including corroded reinforcing steel, so the substrate is sound before any coating goes over it.
