BLOCK-AID® Plugging Mineral Chips
BLOCK-AID® Plugging Mineral Chips is designed to seal and plug voids and porous zones encountered when drilling a borehole or Geotechnical excavation. BLOCK-AID plugging material contains 3/4” sized natural mineral chips. The size of BLOCK-AID is ideal for use as a sealant on any vertical borehole. It prevents and stops slurry loss in the surrounding formation. The high swelling nature of BLOCK-AID fills voids by exerting pressure against all surfaces to create a flexible low permeability seal.
BLOCK-AID easily falls through slurry filled excavations without sticking for a discrete in-situ swelling that delivers an excellent seal. BLOCK-AID is used as a sealant and plugging additive when severe cases of slurry loss are expected to occur. BLOCK-AID is excellent at sealing larger voids, fractures, cobble and boulder zones encountered when drilling.
