Abstract
A process for reinforcing or sealing solid structures or for anchoring bolts using macrocapsules which contain at least one part of a multi-part curable polymer system and which fracture under pressure to produce flake-like fragments that aid in mixing the components of the multi-part curable polymer system. The macrocapsules can be conveniently made a part of a sealing cartridge for ease of use.
