Penetron® Industry Newsletter
President Obama recently underscored what we have known for decades, that waterproofing concrete from the inside can extend a structure's working life for 20 to 30 years (click here for full transcription). It is widely known in the concrete industry that waterproofing concrete is done largely by sealing cracks, which are very much a part of concrete life. Penetron products will self-heal cracks in concrete subjected to water pressure throughout its working life and will protect it from corrosion and strength loss, significantly extending the durability of its structural integrity.
Featured in this newsletter is an effective crack sealing test that was recently done at Concremat in Brazil, where Penetron is now a member of IBRACON (The Brazilian Concrete Institute).

Penetron®Feature: CONCREMAT REPORT ON PENETRON ADMIX CRACK SEALING ABILITY
2 identical concrete samples were prepared, one with the addition of 1% Penetron Admix, and the other without Penetron Admix. Each had a perforated PVC tube cast inside, capable of delivering water pressure throughout the samples. Both samples then had artificial cracks induced by applying the same pressure.
The samples were then subjected to a water pressure of 1.5 MPa for eight weeks and the water flow through the cracks was monitored. Following results were obtained:
The results indicated that the Penetron Admix treated sample was able to reduce water flow through the cracks from 1 liter per hour during the first week to 0.003 liters per hour after the 5thweek. No crack healing was observed on the untreated sample.

Australia – AUDI LIGHTHOUSE
Project: AUDI LIGHTHOSE – 6 Defries Ave. Victoria Park Zetland
Principal Contractor: Southern Cross Constructions
Architect: Johnson Pilton Walker
The flagship Audi Lighthouse is one of the new Terminal-style dealerships being rolled out around Australasia, and will be the world's largest Audi facility. Located adjacent to South Dowling Street in Zetland, the nine-level facility will be Audi's new Australian headquarters. The building will feature 12000 square meters of commercial space, new and used car showrooms, 20-bay service centre and car parking. There were many waterproofing challenges to overcome on this project making the selection of a suitable contractor critical to the projects success. Some of these challenges included a high watertable, unique building facade, vehicular trafficable areas on all levels and large exposed car park roof decks.
Penetron Australia supplied Penetron Admix for all below grade concrete structures (1200m) and Penebar SW-45 for all basement construction joints.

So accurate was the formwork that tiling was applied directly to concrete without the need for plaster. In effect paying in full for the cost of the Penetron.
Cad drawings were supplied by the local Penetron team for all the construction joint details.
So impressed was the client, Penetron Admix was employed in the roof slab excluding specified bitumen torch on membrane completely and again giving huge savings back on contract.
