I'm interested in your waterproofing solutions and would like to know if an aliphatic top coat is necessary for your product. Could you please send over the technical data sheets for all your polyurethane waterproofing systems? We cover a range of applications, including water tanks and flooring. Additionally, if you produce bitumen membranes, I would appreciate details regarding the 4mm APP options, including both sand and mineral chip finishes. Your prompt response will help us proceed with potential supply opportunities in Southern Africa. Thank you!
