What is sheet piling? Sheet piles are sections of sheets of Steel or PVC with interlocking edges that are driven into the ground to provide earth retention and excavation support. Vibratory hammers are usually used to install sheet piles, and Impact hammers can be used if the soil is too hard or dense.
On building projects, sheet piling is often adopted to provide temporary retention for construction of basement, while on civil projects sheet piling is commonly used for riverbank protection, seawalls, cofferdams etc.
Value of sheet piles in a project is high as they can be reused. This sets them apart from other retention/shoring techniques. Traditionally steel sheet piles have been used all across the globe, until as recent as ……. PVC sheet piles have been introduced, which can prove to be very cost effective alternative to Steel sheets, though only if requirement is for permanent works.
Excavator Mounted Vibratory Hammers: Vibratory hammers are highly effective for sheet pile driving in soft and granular soils. Their unique feature lies in harnessing vibrational energy through eccentric weights or hydraulic motors, creating high-frequency vibrations that reduce friction during penetration. The rapid installation in specific soil types further enhances their appeal for efficient and eco-friendly sheet pile driving, especially where minimizing environmental impact is important.
These Hammers have evolved significantly over the years and now there are variants available with tilting mechanism to hold, lift and drive sheet piles in a single operation. If you need to drive upto 8m, you can opt for a unit suitable for a 20T excavator.
Boom Adjust: Simply by adding a gooseneck andmaking a boom adjust mechanism you can increase the 20T excavators pile handling capability from 6-7m to 9-10m. A relatively small investment provides greater capabilities to your excavator.
Vibro Boom & Gooseneck: 30T & 40T excavators can be equipped with gooseneck extensions or Vibro boom attachment to allow you to drive sheet piles upto a depth of 14-16m. Excavator mounted set ups are cheaper in both investment and operating costs. They are more popular all over the globe due to their ease and speed of operation.
Side Grip hammers: In case of space constraints, there are options of excavator mounted side grip vibro hammers. For e.g. if you need to drive sheet piles under a bridge / flyover, you cannot use a crane or a large excavator. In such a scenario, a side grip mounted on a 20T or 30T excavator can drive even up to 14m sheet piles.
Why PVC sheet piles? These are the most durable synthetic pile products in the world. PVC is the material of choice where environmental factors are a concern, as they do not rot, decay, rust, or spall. PVC sheet piles are specifically designed to replace the conventional sheet piles, primarily where the retention is permanent.
Durable: In corrosive environments, PVC proves to be most durable, as wood rots, concrete spalls, and steel rusts. Based on independent testing and analysis, PVC walls can last 75+ years when properly designed and installed. PVC Sheet piles can be driven with vibratory hammers and do not require any other equipment.
Aesthetic: By using the many attractive colours available in sheet piles, a beautiful permanent blends perfectly with marine applications, creating a permanent retention. Depending on the quantity, PVC sheet piles can be manufactured in customised colours as well, elevating the aesthetics of any project.
