TPO Roofing Membranes

TPO Membrane Waterproofing, short for Thermoplastic Olefin, is a highly durable and versatile waterproofing solution ideal for New Zealand homes. This advanced membrane, composed of synthetic rubber and reinforced fabric, provides a seamless barrier against moisture, offering superior protection against leaks and water damage. Its benefits include exceptional durability, resistance to UV radiation, and easy installation, making it an excellent choice for ensuring a dry and secure environment in your home.

Torch-on Membranes

Torch-On Membrane Waterproofing is a popular method where layers of modified bitumen sheets are fused together using a torch, creating a seamless barrier against water. Its benefits include excellent durability, making it well-suited for the diverse weather condition and its ability to withstand UV radiation, ensuring long-lasting protection for your home against leaks and water damage.


Tanking (below ground) Waterproofing is a crucial technique for safeguarding areas below the ground level, such as basements, against water penetration. It involves applying a specialised waterproofing membrane or coating to create a protective barrier, preventing moisture from seeping into the structure. The benefits include safeguarding against potential water damage, reducing the risk of mould growth, and maintaining a dry and structurally sound living space.
