Tubular Piles

Quinn Piling has specialised in developing techniques for the installation of large diameter tubular monopiles, for use both as foundations and berthing/mooring dolphins for clients ranging from Main Contractors to Port Operators.   We employ floating barges, jack-up platforms to support various specialised drilling and grouting equipment to complete installations to suit the many different purposes for which monopiles are now being used.

Rock Sockets

Quinn Piling has developing techniques for the drilling of rock sockets in the range 75mm to 1.5m.  Rock sockets can be employed in high capacity bearing piles and for steel tubular piles in marine application.  The drilling technique used is either rotary or down the hole hammer.

Dredging

We have experience in harbour / marina excavations.  This can involve the excavation of soft material, weak rock our hard rock.  Various techniques are employed from bulk excavation with a track machine to ripping to drilling and blasting.

Rock Blasting

Rock Blasting is normally associated with harbour deepening, quay wall construction, the clearance of navigational channels and pipe lines.
