Product Label

Below is an example of our Allco Product Label. The label was created to be used on site and to support council personnel. When you find this label on site just scan the QR code it will take you to this Council Support page.

Here you will find the most frequently asked question around product installation, lap sizes, terminations and membrane protection on our most frequently used tanking membranes.

Please remember that although encouraged, labels aren’t compulsory and may not be found at every site.

We have also introduced backfill stickers to help ensure the backfill is completed within an appropriate time frame by the contractor.

The sticker has a QR CODE that will automatically download a copy of Allco’s Backfill Document ensuring easy access to the correct information.

The stickers will help with showing installation completion date and encourage backfill to be done by the contractor ASAP which will safeguard the installation and protect the integrity of the product. The stickers will also help the Allco TA team know when the installation was completed allowing them to follow up with the contractors as well.

Our TA Team will also have their own YELLOW STICKER version so they can inform applicators,  council personnel and the contractors of when an Allco inspection has been completed and reinforce the need for immediate backfill.



We have some videos on the correct installation of our tanking membranes. After watching the videos make sure to check your understanding with a short quiz!
