The minimization of water aggregation in building sites is a challenge that confronts builders and plumbers in multi-storey developments. Allplastics Engineering has assisted many builders and plumbing contactors by fabricating custom made White or Grey PVC Gutters or channels to suit the specific situation on site. PVC demonstrates good chemical resistance, good impact strength and can be glued or welded on site if required. The White PVC can be unobtrusive if the surrounding walls are painted white. However, if an “industrial look” is required the grey PVC blends with concrete walls and cement renders.
