Building Envelope Trades
Commercial Waterproofing Estimating Services
Tribuild takes off waterproofing and air barriers by system and location: below-grade, plaza-deck, and above-grade membranes by area, with joints, sealants, drainage composites, and protection carried so the whole envelope system is priced, not just the field membrane.
Waterproofing scope hides in the details: terminations, transitions, and the protection layers over the membrane. Tribuild takes off waterproofing and air barriers by system and location, separating below-grade, plaza-deck, and above-grade work, and carries the joints, sealants, drainage composites, and protection that turn a field membrane into a complete envelope assembly.
Expansion joints and sealants are quantified by linear foot, plaza decks are priced as full assemblies, and every deliverable ships with color-coded plans and sections plus documented assumptions your team can price and defend.
What we estimate for waterproofing
Below-grade waterproofing
Foundation wall and slab waterproofing by area with substrate and system noted.
Blindside waterproofing
Pre-applied blindside membrane at shored/lagged walls by area.
Fluid-applied waterproofing
Liquid membranes by area and coverage rate per the specified mils.
Sheet membranes
Self-adhered and reinforced sheet membranes by area with laps.
Hot-applied systems
Hot rubberized asphalt at decks and split-slabs by area with reinforcement.
Air barriers
Fluid- and sheet-applied air barriers on exterior sheathing by area with transitions.
Vapor barriers
Under-slab and wall vapor retarders by area.
Traffic coatings
Pedestrian and vehicular deck coatings by area and system with wear-coat.
Plaza-deck systems
Plaza and split-slab assemblies with membrane, drainage, and protection by area.
Expansion joints
Waterproofing expansion-joint systems by linear foot at wall and deck.
Joint sealants
Perimeter and control-joint sealants by linear foot by joint type.
Water repellents
Clear and penetrating repellents on masonry/concrete by area.
Protection boards and drainage composites
Protection board and drainage mat by area over the membrane.
Accessories
Termination bars, reglets, detail tapes, and reinforcing fabric by unit and linear foot.

Frequently asked questions
Wall sections, foundation and plaza details, plans, and the waterproofing and air-barrier specifications. Details drive terminations, transitions, and joint scope beyond the field membrane.
Yes, fluid- and sheet-applied air barriers on exterior sheathing are quantified by area with transitions and detailing carried.
As a full assembly by area (membrane, protection, drainage, and traffic coating) since each layer carries its own material and labor.
Yes, joint sealants and waterproofing expansion-joint systems are quantified by linear foot by joint type.
