Turn-Key CSI Division 07 Waterproofing Takeoffs
Waterproofing estimating is one of the most critical risk areas in modern construction. A failure in below-grade waterproofing or plaza deck split-slabs leads to catastrophic warranty claims and structural remediation costs.
At F&K Estimatings, our moisture protection estimators audit foundation structural details, architectural wall sections, civil site connections, and waterproofing manufacturer specifications. We quantify membrane square footages, drainage boards, termination bars, waterstops, and perimeter joint sealants.
We apply industry standards calibrated with the agreed labor and material pricing basis to give your proposals full bidding confidence in 24 to 48 hours.
Scope, price, and delivery are confirmed after reviewing the project documents and requested deliverables.
Waterproofing: quantities, checks and quote requirements
Waterproofing takeoffs measure below-grade and plaza membranes, dampproofing, drainage boards, joint sealants and traffic coatings by area and length.
Measurement and reporting basis
- Below-grade membranes and dampproofing (SF)
- Drainage board and protection (SF)
- Plaza and deck waterproofing (SF)
- Joint sealants (LF)
- Traffic coatings (SF)
Documents to include
- Foundation and below-grade details
- Waterproofing specification
- Geotechnical groundwater information
Also identify the current revision, addenda, project ZIP code, requested trades and bid deadline.
A scope check before pricing
Separate below-grade wall and horizontal deck SF from joint and termination LF. Identify lap, upstand, corner, drainage-board and protection-course quantities from the assembly details.
Scope limits: Waterproofing-system design, substrate inspection and leak testing are excluded; concealed conditions need client evidence.
Worked estimating example
Separate membrane area from terminations
A 100-foot wall at 8 feet high provides 800 SF of vertical field area. Its top termination is 100 LF; corners, laps and penetrations need their own measured or stated basis.
- What the estimate should record
- Identify the field membrane, protection course, drainage layer and transition details separately. Avoid hiding every accessory inside a single area allowance.
- Resolve before pricing
- Which assembly details define laps, upstands and responsibility at adjoining systems?
The written quote defines the deliverables and revision coverage. Measured quantities and drawing markups can be supplied for the agreed scope; a priced estimate adds the identified material, labor and equipment cost basis. Missing information is recorded as a clarification or allowance.
US project coverage for waterproofing
Request remote waterproofing support for projects across all 50 US states. Include the project ZIP code and the location-sensitive inputs below. Quantities-only takeoffs and priced estimates have separate agreed deliverables.
- Include project-specific waterproofing assemblies, substrate details and supplier delivery quotations.
- Identify excavation access, groundwater information where documented and protection requirements separately from membrane area and joint lengths.
The proposal records the pricing date, cost sources and unconfirmed allowances. Explore US service area information or send your project details for a scope quote.
Send the documents above for a written quote confirming the scope, fee and delivery date after document review. Indicate whether you need quantities only, a priced estimate or a review of an existing bid.

Frequently Asked Questions
Do you calculate measured square footage for below-grade foundation membranes?
Yes. We calculate precise square footage for cold-fluid applied, hot-rubberized asphalt, and self-adhered sheet membranes (Bituthene, GCP Preprufe). We include all vertical footing turn-ups, corner fillets, termination bars, and overlap waste factors.
Can you estimate hydrophilic waterstops, bentonite sheets, and injection tubes?
Absolutely. We quantify all expansion joints, PVC ribbed waterstops, hydrophilic bentonite strips at construction joints, and pre-injected re-injectable grouting tubes required for structural water-tightness.
How do you handle dimple drainage mats, protection boards, and root barriers?
Our waterproofing estimators calculate square footage for dimpled HDPE drainage boards with geotextile filter fabric, extruded polystyrene protection boards, and root barrier membranes for green roofs and split-slab plaza decks.
Do your takeoffs include vehicular and pedestrian traffic coatings?
Yes. We provide comprehensive takeoffs for multi-layer polyurethane/epoxy vehicular traffic coatings on parking garages, pedestrian balcony coatings, and mechanical equipment room waterproof flooring including primers and aggregate broadcasts.
What is your typical turnaround for a commercial waterproofing takeoff?
Delivery depends on the drawing set, requested trade scope, pricing requirements and bid deadline. The delivery date, scope and revision coverage are confirmed in the written quote after document review.
