Amitran is a building and development company working primarily in the commercial sector. We have worked with Penetron on a variety of creative waterproofing solutions for close to 10 years. The projects we have worked on have ranged from 1000m2 to 12,000 square meter commercial complexes as well as high end residential houses. The concrete I have poured with Penetron has never leaked or caused any issues. I would highly recommend Penetron to anyone seeking a quality waterproofing solution for concrete.
