Learn about Waterproofers

Waterproofing keeps water out of the parts of a building most exposed to it: bathrooms, decks, roofs, basements and below-ground walls. A waterproofer assesses where water could enter, selects the membrane system suited to each area, and installs it so that junctions at drainage outlets, pipe penetrations and wall-to-floor transitions are sealed. The work has to be complete and checked before tiles, decking or other finishes go over it, so on a new build or renovation, waterproofers work alongside builders and other building and construction professionals to confirm that substrates, falls and penetrations are ready before the membrane is laid. The professionals listed here carry out residential, commercial and remedial waterproofing across New Zealand.

Waterproofing contractors are experts in making a structure waterproof or water resistant. In construction, this is essential to ensure that water doesn’t leak in and cause damage to walls and foundations. Waterproofing companies can work on residential and commercial projects and sometimes specialise in bathroom waterproofing, basement waterproofing, roof waterproofing or providing the waterproofing solution for an entire structure. ArchiPro features only the best waterproofing contractors in New Zealand, ready to work on your next project.

How to choose the best waterproofer for your project

To choose the best waterproofer for your project in New Zealand, some research is required. You’ll have to start off by looking at the company’s profile to ensure they’re reputable.

  • Do you have any other team members or do you work alone?
  • Have you worked on a similar project in the past, and were there any challenges?

FAQs

Do waterproofers need to be licensed?

Waterproofers do not have to be licensed to install waterproofing in New Zealand. However, waterproofing must conform to all the building and structure codes in your local area. While a licence isn’t required, using a licensed waterproofer is highly recommended to ensure that your project is done to the right standards.

How long does waterproofing take to set?

Depending on the temperature and humidity in your area, the time it takes for waterproofing to set can vary slightly. Generally, the waterproofing takes approximately three to five days to cure completely.

How long does a waterproof membrane last?

Quality waterproofing installed by a licensed expert would last about ten years without giving any issues in New Zealand. However, this lifespan is primarily determined by the type of membrane or lining used and the workmanship.

Do you need to waterproof before tiling?

Waterproofing any space where you’ll also be using tiling isn’t necessary. Waterproofing is only used in areas where you can expect water to be, such as bathrooms, kitchens, roofs, decks, balconies and basements. If you want to use tile in these areas, you’ll first need to apply the waterproofing, and once set, you can start tiling.
