Abstract
A method of sealing a hole or anchoring a rod therein by rupturing multipart curable resin components placed in the hole. At least one of the components is placed in pressure fragmentable macrocapsules which form flake-like fragments upon rupture. The flake-like fragments serve as static mixers and cause turbulence thus initiating mixing and curing of the components without requiring rotation of the rod or other mixing device.
