Abstract: Provided herein are novel and improved weight coating systems suitable for use with pipes, particularly pipes that are submerged in liquid, such as water, in environments including oceans, seas, marshes, lakes and rivers. The novel coating systems provided herein comprise an aggregate and a polyurethane binder, wherein the polyurethane binder is a two-component composition comprising an isocyanate component and an iso-cyanate-reactive component. The coating systems provided have increased durability, as well as flexibility allowing for efficiencies related to transportation, storage, use and resistance to corrosive effects. Furthermore, the coating systems are cost effective and have minimal or zero impact on the environments in which they are utilized.
