Estimating & Quoting Software for Waterproofers
Estimating software for waterproofers converts wet area, balcony, basement and roof dimensions from a plan into a priced waterproofing quote — measuring membrane area in square metres, adding surface preparation, priming, the number of coats for the system specified, and lineal metres of bond breakers and angle fillet detailing, then applying your own labour and material rates to produce a professional quote or tender — instead of you scaling areas off a printed plan and totalling coats and detailing by hand. My Trade Hub automates that membrane-area takeoff from uploaded PDF plans and applies your own editable waterproofing rates library, whether you are pricing a bathroom, a balcony or a basement wall, to produce a Bill of Quantities and a client-ready quote or tender.
Key takeaways
- Waterproofing pricing starts with membrane area in square metres for every wet area, balcony, basement wall and planter box, plus lineal metres of detailing.
- System type and number of coats — cementitious, sheet or liquid-applied — change the labour and material rate for the same measured area.
- Angle fillets, bond breakers and surface preparation are frequently priced as an afterthought rather than a dedicated line item.
- My Trade Hub automates membrane-area takeoff from uploaded PDF plans and applies your own editable rates library to produce a Bill of Quantities and quote.
- Waterproofing contractors preparing a priced tender through My Trade Hub report doing so 60 to 75 per cent faster than pricing manually.
Why waterproofing estimating takes so long
Waterproofing estimating takes so long because the price depends on several measurements done correctly first — membrane area in square metres for every wet area, balcony, basement wall and planter box, plus lineal metres of upturns, angle fillets and bond breakers — before a coat count or a labour rate can be applied, so one missed upturn or the wrong coat count throws out the whole quote.
A typical waterproofing job is rarely just one surface. A bathroom or ensuite floor and shower wall upturn, a laundry, a balcony with a membrane under tiles, a basement retaining wall, and a planter box or roof deck can all sit on the same job — and each surface carries its own system, its own number of coats, and its own detailing at penetrations, drains, hobs and joints.
For most waterproofing contractors, working all of that out by hand off a printed plan means measuring floor and wall areas, tallying lineal metres of detailing, and cross-checking coat counts against the system data sheet — squeezed into an evening between jobs, which is exactly when a shower hob or a planter box upturn gets missed.
What’s in a waterproofing takeoff
A waterproofing takeoff is the measured membrane area, in square metres, for every wet area, balcony, basement and planter box or roof on the job, together with the lineal metres of detailing and the surface preparation each surface needs before a coat goes on. A complete takeoff typically covers:
- Wet area floor and wall membrane — bathrooms, ensuites and laundries, measured in square metres by room.
- Balcony and roof deck membrane — area under tiles or pavers, including falls to drainage points.
- Basement and retaining wall membrane — area below ground, where the system and coat count usually differ from a wet area.
- Planter box membrane — area and detailing around drainage cells and overflow points.
- Angle fillets, bond breakers and upturns — measured in lineal metres at hobs, walls, penetrations and movement joints.
- Surface preparation and priming — substrate condition, priming coats, and any levelling before the membrane system is applied.
How My Trade Hub takes off membrane areas from your plans
My Trade Hub’s automated quantity takeoff reads your uploaded PDF plans and measures membrane area for wet areas, balconies, basements and planter boxes automatically — separating floor area from wall upturns and flagging lineal metres of detailing at hobs and penetrations — instead of you scaling each room off a printed plan with a tape measure and a calculator.
Because the takeoff is automated rather than manual, it is 60 to 75 per cent faster than measuring membrane area and detailing by hand, so a set of plans becomes priced quantities in minutes rather than an evening’s work.
The output is a structured, itemised set of areas and lineal metres — not a single black-box total — so you can check every wet area, balcony and basement wall against the plans before a coat count or a rate goes anywhere near a quote.
Pricing waterproofing: rates, systems and coats
Once membrane areas and detailing are measured, pricing a waterproofing job means applying a per-square-metre rate for labour and material against each surface, priced by system type and number of coats, plus a lineal-metre rate for bond breakers, angle fillets and upturns, then adding surface preparation and margin on top.
Rates vary with the system specified — cementitious, sheet membrane or liquid-applied polyurethane — and with the number of coats that system requires, so a basement wall priced at two coats of one system is not the same job as a balcony deck priced at three coats of another.
My Trade Hub’s editable rates library holds your own labour and material rates by surface type, system and coat count, and applies them automatically to the measured areas and lineal metres — so the same rate structure you use on site is the one that ends up in the quote.
| Item | Quantity | Example rate | Example subtotal |
|---|---|---|---|
| Bathroom floor membrane, 2 coats | 6 m2 | $65 per m2 (example) | $390 (example) |
| Shower wall upturn, 1800mm | 4 m2 | $70 per m2 (example) | $280 (example) |
| Angle fillets and bond breaker | 8 lm | $18 per lm (example) | $144 (example) |
| Surface preparation and primer | 1 item | $120 (example) | $120 (example) |
| Total, this extract (example only) | $934 (example) |
Compliance context: AS 3740 and wet area detailing
AS 3740 sets out waterproofing requirements for wet areas in Australian residential buildings, including which surfaces need a membrane and to what height walls and hobs need to be treated in a shower — and it is worth referencing as a line item on a quote so the client can see the detailing is priced to the relevant surfaces, not guessed at.
This is general background only, not legal or compliance advice — the specific requirements for a job depend on the building classification, the water-resistance rating of the finish, and the certifier or building surveyor sign-off for that project, so always confirm the applicable requirements with the relevant authority or a qualified professional before finalising a scope.
Referencing the standard on a quote is about setting client expectations for what is included — floor membrane, wall upturns to the specified height, and detailing at hobs, drains and penetrations — rather than about certifying compliance.
Not a compliance certification
Any reference to AS 3740 in a My Trade Hub quote is context for the client, describing what is being priced — it is not a compliance assessment or certification. Confirm the actual requirements for a job with your building surveyor or certifier.
From estimate to a professional quote or tender
With membrane areas measured and detailing priced, the next step is turning that pricing into a document a client or head contractor can act on — a clear, professional quote for a bathroom renovation or a balcony re-waterproof, or a complete tender submission and Bill of Quantities for a larger multi-unit or commercial package.
My Trade Hub turns the priced takeoff straight into a client-ready quote or tender, with your branding and terms attached, so you are not re-keying the same membrane areas and rates into a separate spreadsheet or Word document.
Because the slow part — measuring the membrane areas and detailing — is already done, producing the quote itself takes minutes, which means you can turn a waterproofing price around the same day the plans land in your inbox.
Common mistakes in waterproofing estimating
Most waterproofing under-quotes come down to a short list of recurring mistakes, all of which are avoidable with a consistent takeoff process.
- Missing a wall upturn or hob height, which understates the membrane area for a shower or wet area.
- Using the wrong coat count for the system specified — cementitious, sheet and liquid-applied systems all carry different coat requirements.
- Under-pricing angle fillets and bond breakers at movement joints, which are easy to leave off a floor-area-only takeoff.
- Forgetting surface preparation and priming as a separate line item, when substrate condition varies significantly between jobs.
- Pricing from an outdated drawing revision, so the membrane area no longer matches the wet areas or balconies actually being built.
How My Trade Hub helps waterproofers win more work
My Trade Hub helps waterproofers win more work by automating the slowest part of the quote — measuring membrane area and detailing across wet areas, balconies, basements and planter boxes — and applying your own rates to produce a priced tender, rather than replacing your pricing judgement with a fixed price list.
Upload the PDF plans and the automated quantity takeoff measures membrane area by wet area, balcony, basement wall and planter box, ready to price by system and number of coats. Your editable rates library holds your own labour and material rates for every system and surface, plus lineal-metre rates for bond breakers, angle fillets and upturns, and applies them automatically to the measured quantities.

Frequently asked questions
what’s the best estimating software for waterproofers?
The best estimating software for waterproofers automates the membrane-area takeoff from your plans — measuring wet areas, balconies, basements and planter boxes, and flagging lineal metres of angle fillets, bond breakers and upturns — and lets you apply your own labour and material rates by system and coat count rather than a generic price list. My Trade Hub performs that takeoff automatically from uploaded PDF plans and produces a Bill of Quantities and a client-ready quote or tender, while keeping every rate and quantity editable so you stay in control of the final price.
is there waterproofing quote software for Australian tradies?
Yes — My Trade Hub is Australian-built estimating and tendering software that automates membrane-area takeoff from uploaded PDF plans for wet areas, balconies, basements and planter boxes, applies your own editable waterproofing rates library, and produces a Bill of Quantities and a professional quote or tender, priced in Australian dollars.
how do you price waterproofing per square metre?
Waterproofing is priced per square metre by measuring the membrane area for each surface — wet area floor, wall upturns, balcony deck or basement wall — then applying a labour and material rate that reflects the system specified and the number of coats it requires, plus a separate lineal-metre rate for angle fillets, bond breakers and detailing at penetrations and joints.
what does AS 3740 mean for a waterproofing quote?
AS 3740 is the Australian Standard covering waterproofing of wet areas in residential buildings, and referencing it on a quote gives the client context for which surfaces are being membraned and to what height — but it is general background, not compliance advice or certification. The specific requirements for a job should be confirmed with the relevant building surveyor or certifier.
how many coats does a waterproofing membrane need?
The number of coats a waterproofing membrane needs depends on the system specified — cementitious, sheet or liquid-applied polyurethane — and the manufacturer’s data sheet for that product, so the coat count needs to be checked against the system actually being used rather than assumed from a previous job.
does My Trade Hub have a free plan for waterproofers?
Creating a My Trade Hub account is free, and gives waterproofing contractors access to the contractor marketplace to browse tenders and receive quote requests. Automated quantity takeoff, the rates library, and tender preparation are part of the paid Starter, Scale and Professional plans, priced in Australian dollars with no lock-in contracts.
what is included in a waterproofing Bill of Quantities?
A waterproofing Bill of Quantities lists every measured item from the takeoff — membrane area by wet area, balcony, basement wall or planter box, surface preparation and priming, number of coats by system, and lineal metres of angle fillets, bond breakers and upturns — each with its own quantity and rate, so a builder or client can see exactly what is being priced.
