HPA HELICAL PILING COMPANY, singapore/ MALAYSIA INSTALLATION OF HELICAL PILE OR SCREW PILE
In 21st century of smart phones & internet, the helical screw piles is not a sophisticated product. However, it continues to serve ever-expanding roles for public utilities structures and in piling construction industry. Why?
SIMPLICITY is the greatest value it reserved. An uncomplicated product with multiple usages carry out by the minimum installation equipments and piling machine, thereby it's reduce piling cost and resources use and resulting to the conventional HEAVY PILE TURN GREEN.
A helical pile/ anchor is screwed into the ground by application of torsion by piling machine, in simple say it is screwing a big screw into soil.
