Beam and block flooring involves laying concrete blocks between supporting cast concrete beams, providing a cost-effective and durable solution. It is easy to install and provides insulation, acoustic resistance, and fire resistance. Custom components can be ordered, and building codes usually allow this method of construction.
Beam and block is a method of pavement construction in which concrete blocks are laid between supporting cast concrete beams. This method can be cost effective and is also extremely durable. A number of companies specialize in the manufacture of beam and block flooring components, and some also provide installation. An advantage of this technique is the relative ease of installation, which allows construction crews with no previous experience to establish a sound floor relatively quickly with some direction.
The beams used in this type of flooring have a finned profile shape, with the wings at the bottom. They are laid at predetermined distances, supported by the surrounding foundations. The construction workers drop the blocks between the beams to rest on the flanges and create a solid floor. The beam and block flooring is suspended and the height of the floor can be determined with the placement of the beams to allow for the creation of a basement below. It can also be used on the upper floors if desired.
An advantage of this floor is the enormous insulating power of the concrete floor. Temperatures inside should remain relatively stable as the floor prevents heat loss or gain, especially when combined with an energy efficient design in the surrounding structure. Beam and block floors can also lend acoustic resistance to the structure, a potential problem in residential homes or factories where there are concerns about the creation of noise pollution.
The concrete floor also resists fire. Fire has difficulty spreading through concrete. The beam and block floor can prevent the spread of fire throughout the structure as well as resist fire from outside. Adding concrete linings and wall materials can increase a structure’s fire resistance. Some models are also specially treated to increase fire resistance and further improve safety.
Companies that produce beam and block floors make a range of standardized products. It is also possible to order custom components for specific flooring projects. The lead time for custom production tends to be longer. The company should be able to provide an estimate to help contractors and construction teams prepare for the project with an accurate timeline.
Building codes usually allow beam and block paving, although in a region where it is not widely used, the building inspector may want more information. Documentation on the floor can demonstrate its strength and durability and provide assurance that it meets construction standards. A wide variety of structures can be erected around this type of pavement, from traditional wood frame construction to rammed earth.
