SYNOPSIS

High risky geologies, including weak and complicated soils (e.g. running sands, sandy silts, marine clays) or fractured rocks (very low RQD, cavities, karsts) present a major challenge for any drilling operation (bored piles) or excavation (diaphragm walls) for building foundation.

The available solutions such as mechanical methods (full length casing), or geotechnical improvement (deep soil mixing, jet grouting), or materials (conventional bentonite, polymer) are widely used. In some cases, they are subject to limitations and undesirable phenomena (collapsing, sloughing, soft toes, reduction in shaft friction) occur remarkably.

In weak geologies, the fluid suspends the cutting foils in the fluid such that silt does not form at the bottom, limiting the interaction between the drilling fluid and the surrounding medium and keeping the substrate stable.


BIODATA OF SPEAKER

DR. HUONG TRAN PHUONG NAM is an inventor of POLDA, a new green-generation drilling fluid for construction foundations. After graduating PhD from The University of New South Wales, Australia in 2006, he has concentrated on researching and developing subjects relating to polymer composite materials for high-end applications, nanocomposites, and advanced drilling fluid additives. He used to work for Institute of Materials Research and Engineering (IMRE, A*Star, Singapore). Currently, Dr. Nam is Founder and CEO of OTESCORP Vietnam.
