What Sustainable Engineering does

Sustainable Engineering is a privately held Australian company, founded in 2019 and headquartered in Meadowbrook, Queensland, that manufactures, installs, maintains, and repairs pavement construction and maintenance systems. The company sells a three-product suite — PotHole Fix (a patented one-step cold-applied pothole repair that chemically bonds to underlying material and works in wet or dry conditions), Pavement Rejuvenation Seal (a copolymer-bonded surface treatment claimed to double the lifespan of new asphalt), and Crack Seal (an ambient-temperature liquid crack sealant) — all manufactured locally using recycled and waste materials with negligible carbon footprint. The technology differentiator versus traditional hot asphalt is cold application, which eliminates HSE risk and removes the need for heating equipment, while supporting sustainability mandates of government and corporate buyers.

The business model is direct hardware sales to enterprise and government asset owners including local councils, airport corporations, mining operators, and commercial property managers. Sustainable Engineering employs an enterprise field sales motion centred on on-site trial demonstrations, with multiple documented council and commercial trials across New South Wales and Queensland (Northern Beaches Council, Bathurst Regional Council, Sydney Airport, Bengalla Mine, McDonald's Australia, Westfield, and others). Revenue is generated through product sales with contact-based pricing. The company has 11-50 employees, no disclosed institutional investors, no disclosed funding rounds, and no publicly reported revenue or ARR. Leadership includes Director Brian McKeon and CEO Robin Tampoe, both with prior senior delivery experience on large-scale infrastructure projects ($400M-$600M) at prior organisations. The operating footprint is exclusively Australian, with no claimed international expansion.

Core offering

Sustainable Engineering manufactures and supplies a proprietary suite of cold-applied pavement construction and maintenance products — PotHole Fix (one-step pothole repair), Crack Seal (ambient-temperature crack sealant), and Pavement Rejuvenation Seal (copolymer-bonded surface treatment). The products are sold to government asset owners, mining operators, airport corporations, and commercial property managers for permanent road and pavement repair without the need for hot asphalt processes.

Product overview

Sustainable Engineering offers a suite of three complementary pavement maintenance products designed for cost-effective, sustainable road repair. PotHole Fix (PHF) is a one-step permanent repair solution for potholes and larger patching works that bonds chemically with existing pavement and works in wet or dry conditions. Pavement Rejuvenation Seal (PRS) penetrates asphalt to seal against UV damage and restore flexibility, potentially doubling asphalt lifespan. Crack Seal is a cold-applied liquid sealant for filling visible cracks without heating. These products can be used independently or in combination for comprehensive pavement remediation. A Pothole Calculator utility tool supports material quantity estimation. All products are manufactured cold using recycled materials with negligible carbon footprint, manufactured locally in Australia.

Products and services

• Pothole Fix (PHF) A one-step, permanent pothole repair product that forms a chemical bond with underlying pavement material. Can be applied in wet or dry conditions by a 1-2 person crew using hand tamping, plate compactor, or roller, and is scaled from small potholes up to heavy patching and carriageway wearing course construction. Sold to councils, airports, mines, and commercial property operators.
• Pavement Rejuvenation Seal (PRS) A surface treatment that penetrates the asphalt mat and bonds via copolymer chemical anchors to seal, protect, and rejuvenate flexible pavements. Reported to double the expected lifespan of new asphalt when applied shortly after placement. Also applicable to compacted earth or engineered granular material as a wearing course. Sold to road and airfield asset owners and contractors.
• Crack Seal A liquid crack sealant applied at ambient temperatures without heating requirements. Applied by pouring into cracks following high-pressure air cleaning, then scraped flush. Provides a permanent seal and can be used in combination with PotHole Fix and PRS for comprehensive pavement remediation. Sold to councils, airports, mines, and commercial property operators.
