Drilling & foundations
Hard rock, faster holes, fewer tooth changes.
Complex 42 is a concentrated drilling additive for hard-rock piling, bored piers, exploration, and geotech work. In documented field trials it has delivered penetration rates up to 3.4x faster, bit life 80–90% longer, and roughly 40–45% less fuel per hole.
4.5x faster cutting Taj Mahal quartzite.
3.5x faster per hole, on half the fuel.
Proof
Hard basalt piling trial — SR60 rig, 600 mm piles, adjacent holes, 1% Complex 42.
| Without | With Complex 42 | Change | |
|---|---|---|---|
| Time per hole | 630 min | 180 min | 3.5x faster |
| Fuel per hole | 436 L | 216 L | 50% less |
| Teeth per hole | 68 | 12 | 82% fewer |
Each treated hole used 3 to 5 liters of Complex 42.
What changes when you add it to your water
- Penetration rate up to 3.4x faster.
- Bit and tooth life 80–90% longer.
- Fuel use down roughly 40–45%.
- Fewer drill-string jams.
- Less wear on bit, bearings, mud pump, and pipe.
- Rig runs quieter with less vibration.
Your stack
Four products, one loop: the additive goes in, the water gets recycled, the slurry gets handled, and the buildup comes off.
The First Cut Test, on your rig
One hole or one shift. We set the dosing rate with your crew by phone and send a before/after log sheet for drilling time, footage, fuel, and tooling changes. The test costs you nothing but an hour.
