“It’s been great working with Penetron for several years, you have provided a great deal of information on the product that you endorse and continual technical information and support when questions are raised during construction. You follow up on the progress of current works and like to keep in touch to hear about the performance of past projects where Penetron product has been used. At this stage since using the various Penetron products in the lift pits, walls and concrete roofs I have had no defects.”
