Not all foundations are driven piles. Some are drilled, with concrete cast in place. The foundation drilling equipment market includes auger drills, rotary rigs, and other equipment for constructing bored piles (also called drilled shafts).
Bored vs. Driven Piles
The [LSI keyword: foundation drilling equipment market] offers an alternative to driven piles. Bored piles are constructed by drilling a hole (using an auger or a rotary drill), placing a reinforcement cage, and then filling the hole with concrete. The foundation drilling equipment market for "bored" piles is preferred in areas with noise restrictions (urban areas) or where driven piles would cause excessive vibration. The foundation drilling equipment market for "cased" holes (using a temporary steel casing to prevent collapse) is used in unstable soils. The foundation drilling equipment market for "continuous flight auger" (CFA) piles (where the auger is drilled to depth and concrete is pumped through the hollow stem as the auger is withdrawn) is a specialized, fast method. The foundation drilling equipment market for "drilled displacement" piles (where a special tool displaces soil laterally rather than removing it) is used to reduce spoil.
The foundation drilling equipment market is segmented by equipment type (drill rigs, augers, casing oscillators, pile drivers), by application (buildings, bridges, towers), and by pile type (bored piles, CFA piles, displacement piles). The foundation drilling equipment market for "drill rigs" (track-mounted or truck-mounted) is the largest. The foundation drilling equipment market for "augers" (helical flighting) is a component market.
Applications for Drilled Foundations
The foundation drilling equipment market serves many projects. High-rise buildings in dense urban areas (where noise and vibration from driven piles would be unacceptable). The foundation drilling equipment market for "urban" construction is growing. Bridges with large-diameter piers (drilled shafts can be very large diameter). The foundation drilling equipment market for "bridge" is significant. Transmission towers and telecommunication towers. The foundation drilling equipment market for "tower" foundations is a niche. The foundation drilling equipment market for "soil" investigation (using drilling rigs to take samples) is a related segment.
As the foundation drilling equipment market continues to evolve, the focus will be on "instrumentation" (sensors to monitor shaft integrity during concreting), on "automated" rigs (with computer-controlled positioning), and on "mud" management (handling drilling fluid). The hydraulic pile drivers segment is the largest by equipment type . The foundation drilling equipment market is the quieter, less-vibratory alternative to pile driving, essential for constructing foundations in sensitive urban environments.
