Concrete piles are our most common type of pile as they offer a good, but above all cost-effective solution if the geotechnical conditions are advantageous. Concrete piles come prefabricated, which means that they are cast in a factory and delivered to predetermined lengths. The casting takes place according to a square profile and is usually reinforced in each corner, but it can also be spiral-reinforced.
Pålab works with all standardized concrete piles such as SP1, SP2, and SP3, and our machine park can handle both support and cohesive piling with concrete as a base. As a complement to cohesive piling, wooden piles can also be used. Since concrete piles are prefabricated, this means that the piles cast in the factory need to be spliced and thus they can not provide the same type of tensile capacity as e.g. steel core piles. On the other hand, concrete piles are extremely reliable in their capacity in terms of compressive strength. We verify the load-bearing capacity of our concrete piles by shock wave measurement, or dynamic test load as it is also called.
