Harkkoasennukset

Harkkoasennukset refers to the process of installing concrete blocks, commonly known as "harkko" in Finnish. This construction method involves stacking and bonding these blocks together to form walls, foundations, and other structural elements. The blocks are typically made from concrete, cement, sand, and water, and their hollow or solid design influences their insulating properties and load-bearing capacity.

The installation process generally begins with preparing a stable foundation, often a concrete slab or strip footing. The first course of blocks is then laid with meticulous attention to leveling and alignment, using mortar or specialized adhesives to join them. Subsequent courses are stacked in a staggered pattern, known as a running bond, to ensure structural integrity and distribute weight evenly. Reinforcement, such as steel rebar, is often incorporated within the block cavities and grouted in place to enhance strength, particularly in load-bearing walls or seismic zones.

Harkkoasennukset are a popular choice in construction due to the durability, fire resistance, and thermal mass properties of concrete blocks. They can be used for both internal and external walls, and the surface can be finished in various ways, including plastering, painting, or cladding. The relatively simple nature of the installation also makes it a cost-effective option for many building projects.
