DuraForce(iwp) is a proactive liquid additive that waterproofs your concrete from the inside by crystalline growth. Unlike most other waterproofers, DuraForce(iwp) is a liquid which is added via a dispenser instead of powdered bags.
DuraForce(iwp) should be added directly to the freshly mixed concrete at the end of the batch process with the tail water. Mix for 7 minutes at full charging speed to ensure complete uniform distribution. DuraForce(iwp) is com- patible with fly ash, portland-limestone cement, granulated ground blast furnace slag, all chemical admixtures, and polyolefin and steel fibers. It does not promote corrosion of embedded traditional steel reinforcement.
