RockWeb is a TSL or Thin, Spray-on Liner engineered for the stabilisation of irregular rock structures. It is capable of spanning gaps in the rock mass due to its unique ability to be sprayed in a "cobweb" like consistency.
Made from a material called Polyurea, it has no solvents or water to evaporate. It is a 2-component reactive mixture similar to polyurethane or epoxy that can be sprayed on dry to reasonably damp surfaces
