HELICAL (SCREW) PILES
Old Technology Re-engineered
We pride ourselves on having an innovative culture where thinking outside the box is encouraged.
- IT’S NOT NEW – it is over 150 years old and has been described as one of the most underrated foundation engineering feats of the 19th century
- The Inventor, Alexander Mitchell was an Irish bricklayer who at 21 years old became blind. He only had 4 years worth of education, however in 1937 he was elected by the ICE. He also won a Telford Medal for his invention.
- Over 1.5 million HSP’s are installed per year in the UK, USA, China, Japan, Canada, New Zealand, Australia. This number is increasing every year.
- The technology has been used for many high profile projects including the 2012 London Olympics, Brighton Pier, Millennium Dome to mention but a few.
- GTL were the first company to design and install in Iraq and Kazakhstan.
- In 1866 Helical Piles were used as a support to Brighton Pier and in 2013 GTL installed additional piles.
- Helical piles are extremely good at with standing the affects of earthquake.
- More than 100 screw pile lighthouses have been built along the east coast of the United States and in the Gulf of Mexico.
- GTL are acclaimed experts in Helical pile technology and mentioned in many technical books and literature.
- GTL have been involved, as Consultants, in producing International standards including the British Standard.
WHY OUR SOLUTIONOne of the most important elements of design is to select the solution most appropriate to the specific client and project requirements. We don’t cut and paste from our last project, as every project is unique. We incorporate local knowledge and international experience to evaluate all relevant factors and predict performance to deliver the best solution. We strive on a challenge and won’t rest until we find the best possible solution that encompasses quality, economics, innovation, and efficiency ultimately to satisfy each client’s individual needs
By reversing the installation process the helical piles can be removed and then re-used leaving a greenfield site
Less reliance on operator skills unlike a pile rig. Minimal instrumentation required to monitor pile installation which reduces human error and calibration problems
