    Large Void Sealing Grouts have long been used for sealing large voids in rock and other materials, mainly in conjunction with dam or tunnel projects (Bowen ). Adaptations of this method to waste disposal sites could include forming a tie-in between a slurry wall and highly fractured or weathered bedrock, and sealing leaks in aquitards.
