Adonis from Polytech Waterproofing Solutions is very reliable, trustworthy and an extremely valuable source of knowledge. I regularly call upon Adonis for advice and information with any waterproofing issues, as well as any general construction issues.


 His friendly and professional approach and attention to detail is second to none and made a somewhat stressful and potential costly situation become a lot easier to deal with; saving both money and more importantly time. I have been using Adonis and Polytech Waterproofing Solutions for over 4 years and will continue to do so for years to come.
