Profiilipaalut

Profiilipaalut, often translated as "steel sheet piles" or "profiled steel piles," are interlocking structural components used in foundation engineering and earth retention systems. They are typically manufactured from steel and have a distinctive cross-sectional shape that allows them to be driven into the ground in a continuous wall. This interlocking mechanism creates a barrier that can resist lateral earth pressure and water seepage.

The primary applications of profiilipaalut include the construction of retaining walls for excavations, cofferdams for dewatering construction sites, seawalls, breakwaters, and bank stabilization projects. Their strength and durability make them suitable for a wide range of soil conditions and environmental exposures. The installation process usually involves driving the piles using vibratory hammers, impact hammers, or hydraulic presses. The interlocking feature ensures that once installed, the piles form a cohesive and watertight structure.

Profiilipaalut are manufactured in various shapes and sizes, offering flexibility for different project requirements. Common profiles include U-shaped, Z-shaped, and straight web piles, each with specific structural and hydraulic properties. The choice of profile depends on factors such as the required load-bearing capacity, water tightness, and the nature of the soil. The use of steel sheet piles is a well-established and cost-effective method for temporary and permanent earth retention.
