About CreteSeal
Owner-operated. Fully licensed.
CreteSeal is Gerard Billing — a NSW licensed waterproofing technician based on the Coffs Coast.
The short version
CreteSeal specialises in waterproofing, concrete repair and protective coatings, with work that runs from domestic showers and garage floors to council water supply tanks. The business is owner-operated: Gerard quotes the job, does the work and stands behind it.
Why licensing matters
In NSW, waterproofing is licensed work for a reason — failed membranes are among the most common and costly building defects. Gerard holds NSW waterproofing technician licence 181037C, and every membrane is installed as a compliant system under the NCC, AS 3740, AS/NZS 4858 and other applicable Australian Standards and codes.
The business is fully insured for work throughout NSW, so builders, certifiers, strata managers and homeowners are covered.
