Sealing and Chemical Barrier for Well and Drilling Applications
HoleBlok® composite particle system from AquaBlok® offers the following benefits compared to other pellets and chips:
- High-percent solids—Produces a self-compacting seal at bottom of annular area.
- Less mechanical bridging—Pebble shape minimizes sharp angles.
- No "blinding off" the bentonite center as has been shown with core of pellets.
- Faster drop velocity—More than 30% faster than chips.
- Higher mass and bulk density.
- Maintains structural support of seal in vadose zone.
- All HoleBlok products can be delivered by tremie, if required.
