Moisture barriers help to avoid ‘rising damp’

Specialists in installing ground moisture barriers

Moisture Barrier Installation

In fact, many New Zealand houses would benefit from moisture barrier (vapour barrier) installations. For the temperature problem, heating and insulation are the obvious solutions. When it comes to dampness, on the other hand, a lack of ventilation and moisture coming from the ground should be high on the list of priorities.

Meet the moisture (vapour) barrier.

The figures impress when you think about it. Even dry ground will produce 25 kg of water in a single day (!!!). For the 1.2 million New Zealand homes with a suspended timber floor, that’s dampness that can go straight into your house!

Moisture barrier in rental properties.

It’s no surprise that the Healthy Homes Standards for rental properties require you to install a ground moisture barrier. In other words, the vapour barrier should be in place for all rentals with an enclosed subfloor space.

Moisture barrier in your home.

In general, it makes sense to lay a moisture barrier to avoid ‘rising damp’ anyway – regardless if it is a rental property or your home.  After all, nobody wants a mouldy and unhealthy home for their whānau. So, make sure your underfloor insulation is also installed properly as the ground moisture barrier can’t do the job just by itself.
