What is Sheet Piling
Sheet piles are narrow sheets of material, designed with an angular profile and with interlocking edges, so that multiple sheet piles can be fitted together to form a structurally sound and often watertight wall or barrier.
They are usually made of steel but wood can also be used. Steel Sheet Piles are often manufactured using sustainable recycled metals and, where soil chemistry requires it, they are sprayed with an anti-corrosive coating.
Steel sheet piles are the most commonly used type, as they are very versatile. They can be welded or bolted together vertically to provide a greater length or depth, if required.
They are very resistant to the pressures caused by driving and provide the best strength option, compared to their weight.
Sheet Piling
Sheet piling can be used to provide permanent foundations, permanent or temporary retaining walls and as extremely strong shuttering when a poured concrete foundation or retaining wall is required. Sheet piling can form the basis for an underground structure such as a basement or underground car park. Sheet piling can used by projects requiring retaining walls along riverbanks or canals, or in projects focused on bridge repair and building.
Installing Sheet Piling
The narrow sheets or sections are driven into the soil using vibratory hammers or impact hammers, if the ground is hard or particularly dense.
