Cutting-Edge Piling Techniques: Revolutionizing Foundation Construction

Piling is an essential process in construction that provides the foundation and support for buildings and various structures. Over the years, significant advancements have been made in piling techniques, resulting in improved efficiency, cost-effectiveness, and sustainability.

Traditional piling methods like driven piles, such as timber, concrete, and steel piles, and bored piles, which involve drilling into the ground and filling the hole with concrete have served the industry well but innovations in piling have brought about new possibilities.

Pioneering engineers and architects have introduced a series of ground breaking advancements in piling techniques. From the utilization of new materials to the introduction of innovative machinery, these advancements have revolutionized the field of piling, paving the way for safer, more efficient, and structurally superior foundations.

Zero Trim Pile Technique

Standard practice for bored concrete pile construction is to over-pour the concrete and crop the piles down after curing to ensure they are sound at cut-off level. Breaking out the excess concrete in this traditional method can cause a lot of health problems to workers, including hand-arm vibration syndrome, hearing loss and silicosis.

The zero trim pile technique eliminates the need for cropping by sucking out wet concrete above cut-off level. The new zero trim pile technique uses a vacuum excavator to suck out excess concrete when still wet rather than wait for it to set and then cut it out. Eliminating the need to break out excess hard concrete makes the process safer and quicker.

This technique could be transformational for the construction sector, reducing the health risk that results from breaking piles. There are also other positive benefits of this technique. Zero trim uses significantly less concrete, leading to significant improvements in carbon reduction. Zero trim also reduces the time required on site and, through not having to break-out excess concrete, is significantly quieter.

Press-in Piling Method

The decreasing availability of land in urban areas, and the increasing demand for urban development is leading to the construction of taller and heavier buildings at increasingly marginal sites. However, the urban environment is not suited to pile driving. Conventional dynamic installation techniques (i.e. drop hammer or vibro-piling) induce vibrations and settlement in a zone close to the pile, and cause noise and dust pollution. Pile driving vibrations thus damages the existing structures in urban areas.
