We specialize in bored piling with diameters ranging from 200 mm to 2000 mm and depths up to 50 meters. Using advanced hydraulic rotary rigs, we execute piling operations efficiently across a wide range of soil conditions. Our fleet includes high-performance rotary drilling rigs capable of working in restricted headroom areas while delivering precision, stability, and high productivity.

Secant pile walls are constructed by intersecting reinforced concrete piles to form a continuous retaining structure. Primary piles are installed first, followed by reinforced secondary piles after sufficient curing. This technique provides excellent groundwater control and soil retention, making it ideal for deep excavations, basements, and foundation support in challenging ground conditions.

The Manual Auger Method is a reliable piling technique suitable for locations with restricted access or where low noise and vibration are essential. A tripod and manual winch system are used to drill boreholes using a helical auger. This method is commonly employed for pile diameters ranging from 250 mm to 1000 mm and offers an economical solution for smaller foundation projects.

Our Truck Mounted Rotary (TMR) rigs utilize continuous bentonite slurry circulation to stabilize boreholes during drilling. Auger drilling is performed to the required depth while bentonite slurry supports the excavation and carries excavated soil back to a recycling tank. This method ensures bore stability, efficient spoil removal, and high productivity, particularly in loose or soft soil strata.

The DMC Pile Method employs Mendola-type rigs combined with bentonite drilling fluid for safe and efficient pile construction. Surface soil is loosened using a bailer before drilling continues with a percussion chisel. Bentonite slurry stabilizes the bore while transporting excavated material to settling pits. Once the desired depth is achieved, the drilling tools are removed and the final depth is verified before reinforcement and concreting.

This method utilizes tractor-mounted rotary drilling rigs for fast and economical pile boring. Auger drilling is carried out to the required depth, with DMC rods added progressively to achieve deeper penetration through varying soil strata. It is particularly suitable for medium-depth foundation works and offers drilling capacities of up to 16 meters with excellent operational efficiency.
