Sheet piling works at the Greenpark Way site

What we are doing

We are planning to carry out piling works at our Greenpark Way Site in Greenford from late-April 2021 for up to two weeks. These works are needed to stabilise and protect the ground while we build a ventilation shaft at this site.

Our piling method

Sheet piles are commonly used for retaining walls and underground structures to provide stability and support during excavation works. These are sections of sheet metal with interlocking edges that are pushed into the ground along an area where future excavation work will take place. When arranged side by side, the sheet piles form a wall to provide permanent or temporary earth support.

We are planning to use a silent piling method, called Silent Giken, to push the sheet piles into position. This means that the sheet piles can be installed with reduced noise and vibration. This is often called press-in piling or vibration-free piling, which uses the reaction from previously installed piles to install the adjacent sheet piles.

Noise and vibration monitoring will be in place throughout these works. We will use water sprays to reduce dust generated during our construction activities.

What to expect

There will be heavy goods vehicle movements and deliveries to our Greenpark Way site prior to the
start of the sheet piling works. During the works, you may notice large construction equipment and
machinery in our site during these works including:

• Heavy goods vehicles
• Piling and excavating machinery
• Cranes
• Lighting towers
