Ground Moisture Barriers: No Worries About Rising Damp


Stop Mould Where It Starts.


Did you know that up to 40 litres of moisture can evaporate from the ground under your home every single day? This "rising damp" is a leading cause of mould, musty smells, and high heating bills.


At Brightr, we install high-grade polythene ground moisture barriers to seal off that dampness at the source. It’s the simplest way to ensure your home stays dry, your air stays healthy, and your home stays protected.

What is a ground moisture barrier?


A ground moisture barrier is a heavy-duty polythene sheet laid across the earth under your home. It acts as a permanent shield, stopping moisture from entering your floorboards and living spaces.


Why it’s a "No Worries" addition:


  • Healthy Homes Compliance: A moisture barrier is a mandatory requirement for most rental properties under New Zealand standards.
  • Double Up: We can efficiently install your barrier at the same time as your underfloor insulation. One visit, No Worries.
  • Long-Term Protection: It prevents timber rot and keeps your insulation dry so it performs at its best for years.


Professional Installation, Every Time.


Don't let unseen moisture compromise your family's wellbeing. Work with Brightr and we’ll help you get it right. No Worries.

Meeting the Healthy Homes Standards?


If you own a rental property, a ground moisture barrier isn't just a good idea, it’s often a legal requirement. 

To meet the NZ Healthy Homes moisture ingress and drainage standard, a ground moisture barrier must be installed if the subfloor space is enclosed.


Why partner with Brightr?


  • Compliant Installation: We ensure the barrier is lapped and fixed to NZS 4246 standards.
  • Record Keeping: We provide the documentation you need for your compliance records.
  • Stress-Free Solution: We’ll check your drainage and barrier in one visit. No Worries, just compliance.
