Three options. Only one actually works for your business.
You're the trade nobody Googles until something has already leaked
Waterproofing is the only trade where customers don't go looking for you in advance. The bathroom waterproofer is a paragraph in the tiler's quote. The balcony waterproofer is an afterthought after the carpenter laid the deck. The basement waterproofer doesn't get a call until the ground floor smells like a wet dog after winter rain. By the time the customer Googles, something has already failed, and they're picking between the bloke who turned up first and the bloke whose page mentions the right standards. The structural problem is that everyone with a brush calls themselves a waterproofer: the tiler who slaps a coat of Davco on the floor before the screed, the painter who 'does balconies', the handyman who reckons silicone is the same thing. None of them know AS 3740, AS 4654, or AS 2870. None of them issue a third-party waterproofing certificate that the builder, the strata manager or the insurer can actually file. And the real waterproofing contractor, with the WPA membership and the proper Ardex / Mapei / Sika system spec, loses the quote to the bloke who undercut by 30% and won't be there in two years when the substrate fails.
Good waterproofer marketing is three things, in this order: a service-page library that splits the trade by application (a wet-area AS 3740 bathroom page per suburb, plus dedicated pages for AS 4654 balcony, AS 4654 roof, planter-box, AS 2870 below-ground basement tanking, retaining-wall waterproofing, plant-pot, and pool waterproofing) so each builder or homeowner lands on the right standard for the right job; a Google Ads structure with separate ad groups for the residential bathroom-and-balcony tier ($1500-$4000), the commercial balcony-and-roof tier ($5K-$15K), and the high-margin remediation-of-failed-waterproofing and basement-tanking work ($20K-$80K), each driving to a landing page with the right Ardex / Mapei / Sika / Davco / Bostik membrane spec, the standards called out (AS 3740, AS 4654, AS 2870), WPA membership in the trust strip, and the third-party certificate prominently offered; and a Google Business Profile loaded with membrane-pour photos categorised by application, ten-year-warranty language in the description, and twenty-plus reviews mentioning specific jobs. Get this right and the tiler stops sub-contracting you at a day rate and you start getting builder-spec and strata work direct.
Six agents, working in your accounts.
Account Lead, Web, SEO, Advertising, Social Media, and Content. One platform, one bill, you approve the work.
Builds your annual plan around the work that actually pays (third-party-certificate bathroom and balcony work, remediation of failed waterproofing, basement tanking) instead of being the tiler's day-rate subbie. Briefs the other agents so the suburb pages, the ad groups, the social cadence and the builder-and-strata outreach all push toward direct builder-spec and strata work, not the throw-in line on a tile quote.
Imports your existing site so you stop paying for hosting plus a CMS subscription. Ships separate pages per application (AS 3740 bathroom, AS 4654 balcony, AS 4654 roof, planter box, AS 2870 below-ground basement tanking, retaining wall, plant pot, pool) with the suburbs you cover under each, the right membrane system specified per application (Ardex WPC for wet area, Mapei Mapelastic for shower, Sika Sikalastic for balcony, Davco for retrofit, Bostik for niche), and a quote form that asks the right questions (substrate type, square metreage, certificate required yes / no).
Goes through your live site for the things that actually move waterproofer rankings: Waterproofing Service schema (not generic Contractor), AS 3740 / AS 4654 / AS 2870 compliance language on every service page, WPA membership and 10-year-warranty signals on every trust strip, internal links from suburbs into the right application page (older brick suburbs into the remediation page, new-build suburbs into the bathroom page), and a Google Business Profile with every application and warranty attribute ticked. Auto-applies the low-risk fixes.
Runs separate Google Ads campaigns per application and tier: residential bathroom ads ($1500-$4000), balcony and roof ads ($5K-$15K), and a high-margin remediation-of-failed-waterproofing and basement-tanking ad group ($20K-$80K) with a higher CPC because the search volume is small but the intent is unmistakable. Drops the broad 'waterproofer [city]' bid entirely (mostly tile-day subbie enquiries). Switches Meta on for the visual remediation work where the before-and-after photo of a saved basement sells the quote.
Turns every job you finish into a post in your real accounts: a Mapei Mapelastic shower bay in Parramatta, a torch-on bituminous balcony in Bondi, a Sika polyurethane planter box in Surry Hills, a remediation tanking on a Newtown basement that smelled like a wet dog when you started. Builds the membrane-in-shot credibility that wins the builder and the strata manager comparing three quotes. You upload one photo per job, the agent drafts in your voice, you approve.
Drafts the long-form pieces builders and strata managers Google before they book a waterproofer: 'how to tell if your bathroom waterproofing has failed', 'AS 3740 vs AS 4654, which standard applies to my job', 'what is a third-party waterproofing certificate and why does the insurer want one', 'cost of basement tanking remediation in Sydney'. Two drafts a month, in your voice, that pull the researching builder and the strata manager weeks before they ring for a quote.
Your first 30 days.
- Annual plan tilted to direct builder-spec and strata work that pays the third-party-certificate margin, instead of being the tiler's day-rate subbie
- Google Business Profile flipped from 'Contractor' to 'Waterproofing Service' with Bathroom Remodeler and Foundation Repair Service as secondary categories
- AS 3740 / AS 4654 / AS 2870 compliance, WPA membership, 10-year warranty and third-party-certificate-issued attribute wired into every page footer and ad copy
- Service pages indexed across your three core areas for AS 3740 bathroom, AS 4654 balcony, AS 4654 roof, planter box, AS 2870 below-ground basement tanking and remediation of failed waterproofing
- Google Ads live on '[suburb] bathroom waterproofing', '[suburb] balcony waterproofing', 'remediation failed waterproofing [suburb]' and 'basement tanking [suburb]', driving to application-specific pages with the right membrane brand
- High-margin remediation ad group running separately at a higher CPC for the $20K-$80K basement-tanking and remediation work
- Waterproofing Service schema deployed with AS-compliance, warranty and third-party-certificate markup
- Wet-set-membrane caption library running with the Mapelastic shower bays, Sika polyurethane balconies, torch-on bituminous roofs and remediation tankings on your phone
- 'How to tell if your bathroom waterproofing has failed' and 'AS 3740 vs AS 4654: which standard applies to my job' explainers drafted for approval
- Outreach drafted to two strata managers and two bathroom-reno builders in your patch about the third-party-certificate workflow and the remediation niche
Waterproofers lose the high-margin work not because the membrane is worse, but because the search results put a WPA-member contractor with a proper Mapei or Sika system, AS 3740 compliance and a third-party certificate next to the painter with a tin of Davco, and the builder cannot tell them apart on the quote. The fix is a service-page library that shows the wet-set Mapelastic photo from yesterday's bathroom, ad groups split between bathroom, balcony and the high-margin remediation work, and a Google Business Profile that proves the certificate is on the desk before the tiler returns.
Agencies are too dear to actually run the application-by-application page library and the remediation ad group for $3.5k a month. Tools are cheap but you write the AS 3740 explainer between prep days and the third-party certificate stays unmentioned. In-House is the third option: for $299 a month the agents ship the pages, launch the bathroom and balcony and remediation ad groups, post the membrane photos, and keep your Google Business Profile beating the painter-with-a-tin listings. Two taps to approve, minutes a day. Stop being the tiler's day-rate subbie.
