Certificate III in Construction Waterproofing

Suited to

Qualified trade contractors and builders involved in waterproofing projects.          

Why enrol

Internal and external waterproofing is one of the top ten building defects home owners and building managers complain about. The average cost of repairs for a waterproofing defect is between six and ten times the original cost of the work. This could equate to $6,000 to $10,000 to fix a basic defect.

Fixing waterproofing problems is expensive and is generally the responsibility of the builder to have rectified.

Our Certificate III in Construction Waterproofing will equip you with the skills and knowledge to ensure building projects are waterproofed correctly and reduce risks. 

This course allows trade contractors to become dual traded, allowing for diversity in revenue streams and increasing their longevity in the industry. Builders who undertake the course can gain a higher level of knowledge and provide better supervision of waterproofing work. By providing this supervision it will help them to reduce risk.
