Henry Drilling specializes in deep foundation services, including cast in drilled hole piles, continuous flight auger piles, soldier piles and lagging, secant pile walls, tangent walls, rock drilling and gas extraction wells at landfills. We have the largest, most modern drilling fleet in British Columbia, including a Bauer BG36, Bauer BG28, Bauer BG18, Soilmec SR-80, Soilmec SR-75, Soilmec SR-50 and Soilmec SR-30s. We have more than 30 years experience in the drilling business, and our specialty is tackling jobs that few other companies can do. Call us today to find out how we can help you.
Tunnel Boring for Rapid Transit,
Port Moody, B.C.
This project saw us deploy three drill rigs to construct a secant pile wall that will allow a tunnel-boring machine to drill through Burnaby Mountain. We completed 150 secant piles 3’ in diameter up to 70’ deep in a month.
Evergreen SkyTrain Line,
We are in the midst of completing 33 drilled shafts as part of the new SkyTrain project. We currently have two drills, two cranes, two 2-metre oscillators and support equipment on site for these shafts, which range from 6’ to 9’ in diameter.
Continuous flight auger piles combine the advantages of driven piles with the versatility of bored piles. This drilling method allows piles to be excavated in a wide variety of soils - dry or water-logged, loose or cohesive - and also to penetrate through low-capacity, soft-rock formations, loamy clays, limestones and sandstone, etc.
No shocks or vibrations are induced when this method is performed. This, combined with modern sound-proofed drilling equipment, makes CFA the most convenient piling method for construction in town centres.
The execution of the pile without decompression of the soil permits us to work close to existing structures. With this in mind it is much easier to install piles in collapsing soils with no need for casings or drilling slurry.
The soil brought up to the surface is reduced by as much as 50 per cent compared to bored pile excavations. This is due to the auger displacing and compacting the soils as it advances. The result is less excavated material that has to be transported to a disposal site.
The range of diameters (from 40cm to 140cm) and depths (from 25m to 33m) makes it possible to overcome problems connected to the project and execution of the pilings.
Bored piles are the most versatile and used technology in deep foundations around the world.
Why? Because drilling diameters do not have limits, no permanent - and expensive - steel casing is required. Bored piles can be installed through layers of solid rock and other debris with no vibration and very little noise. Plus, depths can reach more than 80 metres, making them suitable for almost any job.
Henry Drilling can provide you with a quality drilled shaft in all types of drilling conditions. Whether it means using drilling slurry to keep the holes open or installing full-depth temporary casings, we have the equipment needed to get the job done on schedule and on budget.
Whether it is small diameter piles with 100' depth or larger diameter piles in excess of 200' depth, we will be able to assess if drilled shafts can save you money.
TYPICAL HOLE DIAMETERS ARE 16" TO 144"
TYPICAL HOLE DEPTHS RANGE FROM 10' TO 200'
