PMRpohjaiset

PMRpohjaiset refers to a specific type of foundation or base used in various engineering and construction applications. The term "PMR" stands for "Pohjalevy, Maalijuoste, ja Raekivi," which translates to "Base Plate, Subgrade, and Rock Base" in English. This type of foundation is commonly employed in the construction of buildings, bridges, and other structures where a stable and durable base is essential.

The PMRpohjaiset foundation system typically consists of three main components:

1. Base Plate: This is the top layer of the foundation, usually made of concrete or reinforced concrete. It provides a level and stable surface for the structure above and distributes the load evenly.

2. Subgrade: The subgrade is the layer of soil or other material immediately below the base plate. It is compacted and prepared to ensure a stable and even surface for the base plate.

3. Rock Base: The rock base is the layer of rock or other stable material beneath the subgrade. It provides additional stability and support for the structure.

The PMRpohjaiset foundation system is chosen for its ability to provide a stable and durable base for structures, even in challenging soil conditions. It is particularly useful in areas where the soil is weak or unstable, as the rock base provides additional support. The system is also beneficial in areas prone to seismic activity, as the rock base can help to absorb and dissipate seismic energy.
