Licensed Waterproofing Company Servicing Newcastle & Hunter

Newcastle’s most trusted waterproofing company u2014 AS 3740 compliant work for bathrooms, balconies, basements and commercial structures across the Hunter Region.

Waterproofing the Hunter Region u2014 Local Knowledge, National Standards

The Hunter Region presents a distinct set of waterproofing challenges that differ meaningfully from Sydney’s inner-city environment. Newcastle and the surrounding area u2014 including Lake Macquarie, Maitland, the Hunter Valley, and Port Stephens u2014 has a climate characterised by wet summers, significant rainfall events associated with east coast weather systems, and coastal areas with high salt air exposure. Combined with the Hunter’s predominantly clay-rich soils, which expand and contract significantly with moisture changes, these conditions place demanding and specific stress on waterproofing systems in both residential and commercial buildings.

Econyc’s waterproofing teams in the Hunter have direct experience with local conditions. We understand how the Hunter’s coastal and riverside locations affect concrete and masonry, how the region’s clay soils behave under load and seasonal moisture change, and how local building practices u2014 particularly in the region’s older housing stock u2014 affect what we find when we investigate a waterproofing problem. This local knowledge informs our product selection and our process design.

At the same time, we apply the same national standards u2014 AS 3740, AS 4654, and the National Construction Code u2014 to every job we do in Newcastle as we do in Sydney. Local knowledge and national compliance are not in tension: they work together to produce waterproofing that is right for the environment and legally compliant.

Our Step-by-Step Process

Every Econyc project in the Hunter Region u2014 from a single shower repair to a commercial remediation program u2014 follows the same structured process:

Free site inspection u2014 one of our licensed technicians attends the site, inspects the area, and identifies the cause of the waterproofing issue. We do not quote without inspecting u2014 phone quotes for waterproofing work are not reliable.
Written report and fixed-price quote u2014 following the inspection, we provide a written diagnostic report (for remedial projects) and a fixed-price quote documenting the scope, method, products, and timeline. No surprises.
Scheduling u2014 we schedule the work at a time that suits the client. For residential work, we provide a clear timeline. For strata and commercial work, we coordinate with building managers on staging and access.
Surface preparation u2014 the work area is prepared correctly: failed material removed, substrate repaired as necessary, area cleaned and dried. Good preparation is the foundation of a lasting result.
Waterproofing application u2014 applied by our own licensed waterproofing contractors using Normet, Sika, and Tremco products. We do not subcontract the waterproofing application.
Flood test u2014 all wet areas and balconies are flood-tested before handover. No exceptions.
Compliance certificate u2014 issued within 48 hours of completed flood test. Includes our licence number, product details, and test results.

Products We Use u2014 Normet, Sika & Tremco

Across all of our Hunter Region work, Econyc uses only top-tier products from Normet, Sika, and Tremco. We do not use generic or unbranded waterproofing products, and we do not dilute or under-apply products to reduce cost.

Normet provides our injection systems for crack and joint repair. The Normet TamPur range (116 and 220) covers polyurethane injection for active water ingress in basements, retaining walls, and below-grade structures. Normet’s products are used on major underground infrastructure projects in Australia and are specified for demanding conditions.

Sika provides our liquid membrane, crystalline, and cementitious waterproofing systems. Key products used in the Hunter include Sika TanDrain and SikaTite-N (liquid membranes for wet areas and balconies), SikaTop 122 Plus (cementitious waterproofing for concrete substrates), and Sikaflex Pro-3 (polyurethane sealant for joints and penetrations).

Tremco provides our sealant range and below-grade membrane systems. Tremco Dymonic 100 is used for high-movement joints in balconies and wet areas, Tremco TREMproof 60 for liquid membrane applications, and Tremco Paraseal LG for external below-grade membrane work on new construction.

Frequently Asked Questions u2014 Waterproofing Newcastle & Hunter

Are Newcastle waterproofing prices the same as Sydney?
nOur pricing in the Hunter Region is comparable to Greater Sydney for the same scope of work. Travel costs do not significantly affect pricing within the Newcastle metropolitan area. For remote Hunter Valley locations, a small travel charge may apply for large commercial projects u2014 this is always disclosed upfront in the quote.

Can you provide a waterproofing certificate for an older Newcastle home?
nYes. We can inspect existing waterproofing in older homes and issue a certificate if the waterproofing passes inspection and flood testing. If the original waterproofing does not meet the current AS 3740 standard, we will advise on what remediation is required and provide a quote before any certification is issued.

Do you handle strata waterproofing in Lake Macquarie and Newcastle?
nYes. We work with strata managers and owners corporations across the Hunter Region on both planned maintenance waterproofing and defect rectification. We provide condition reports, remediation specifications, and compliance certificates in the format required by strata committees and their lawyers.

How soon can you start a waterproofing job in Newcastle?
nFollowing inspection and acceptance of our quote, we can typically commence residential waterproofing within 5u201310 business days. Commercial and strata projects are scheduled in consultation with the building manager u2014 urgent situations (active leaks causing damage) are prioritised and can often be attended within 48u201372 hours of quotation acceptance.

What is the most common waterproofing problem you see in Newcastle homes?
nBy far the most common issue is shower membrane failure u2014 typically in bathrooms renovated in the 1990s and 2000s where waterproofing was either applied by an unlicensed person, applied below the required coverage, or where the membrane product has simply reached end of life. The second most common issue is balcony membrane failure in apartment buildings, which is a growing area of work as Newcastle’s apartment stock ages.
