Precision Drilling for 
Foundations, Anchors and 
Specialist Ground Works
PDS Piling & Foundation Contracting LLC provides specialist drilling works for 
piling, anchors, micropiles, shoring and other foundation engineering 
applications across the UAE and India. Drilling is a critical first stage in many 
ground-engineering systems, and its accuracy directly affects depth, alignment, 
reinforcement installation and final structural performance.
Our teams select equipment, tooling, casing and flushing methods according to 
the approved design, ground profile, bore diameter, depth, access and 
environmental constraints. We can coordinate drilling through soil, fill, 
obstructions, weathered formations and rock using appropriate rotary or rotary-
percussive techniques.

Why Drilling Works?
Every drilling operation is planned around safe rig positioning, working-platform capacity, spoil management, 
utility protection, bore stability and clear quality records

Frequently Asked Questions
What types of drilling does PDS Piling provide?
PDS Piling undertakes drilling associated with bored piles, micropiles, anchors, 
soldier piles, shoring and other defined foundation-engineering works.
How is a drilling method selected?
Selection considers diameter, depth, soil or rock type, groundwater, bore stability, 
access, environmental controls and the element to be installed afterward.
What is temporary casing used for?
Temporary casing can support unstable near-surface or deeper ground, reduce bore 
collapse and help control soil or water entry during drilling.

Frequently Asked Questions
Can drilling be carried out in rock?
Yes, subject to the rig, tooling, required diameter, rock strength and project scope. 
Rotary or rotary-percussive methods may be selected.
How are underground utilities protected?
Available utility records are reviewed, required clearances and permits are obtained, 
and safe exposure or scanning procedures are coordinated before drilling.
Can drilling be performed with limited headroom?
Compact or low-headroom equipment may be suitable for some applications, 
provided access, ventilation, lifting and safe working clearances are available.
