Krete products all use the same award winning and proven formula providing exceptional durability and longevity. This adds up to a "fit and forget" maintenance system suitable for flat roofs, green roofs, balconies/terraces,  walls, air-tight barriers, basements, and earth shelter buildings.

Krete products all have exceptionally low embodied energy numbers when compared to all the alternative petrochemical based roofing/ waterproofing materials –like single ply PVC, single ply TPO, bitumen membranes, mastic asphalt and all liquid plastic waterproofing systems. Lower embodied energy means better sustainability. The product with the longest life/most durable is also the most sustainable.

European University College Brussels (EHSAL) have just completed a comparison report on the sustainability of major European waterproofing membranes including single ply PVC, single ply TPO, bitumen, mastic asphalt, and liquid waterproofing systems.

The report highlights the importance of "embodied energy " and "transport embodied energy " and durability/ long life.
The report is now available on Google Documents via this link:
