  Report on Performance Assessment of Penetron Waterproofing Admixture
  Results: Penetron Admixture has evidently reduced the porosity and permeability even of a water tight control and laboratory prepared concrete without reducing the water cement ratio. The improvement is expected to be more pronounced in concrete of lower quality and concrete cast in-situ. The coefficient of water permeability of the treated concrete is in the range of 10-13 m/s. Based on the guidelines given in DIN 1045, the treated concrete complies with the requirements for water resistant/waterproof concrete.
12/1/2002 Report: ACCI REF. NO. 58324
  The Australian Centre for Construction Innovation, Properties of Type GP Cement Concrete Modified with Penetron Admix
  Water Permeability Test (ACCI Method)
  Results: According to a review of permeability test methods published by British Concrete Society, concretes with permeability coefficients below 1 x 10-12 are considered to be very good while concrete with permeability coefficient between 1 x 10-12 m/sec are considered to be acceptable.

10/10/2005 REPORT NO. 05-4070A
  Sor Testing Laboratories, Inc., Cedar Grove, NJ
  Laboratory Tests of Penetron Admix in Concrete
  Results: As per ASTM-D 5084, the Penetron Admix treated concrete showed improvements of an average permeability of 2.45 x 10-10 cm/sec over the control (untreated) concrete of 3.66 x 10-8 cm/sec.
