Limestone occurs in ancient marine environments where pressure compresses bits of shells over time. Most limestone contains other impurities besides its calcite base, creating beautifully colored and textured stones that are much in demand in construction projects.

Construction companies frequently use limestone for outdoor landscaping. Builders may also use the stone indoors for limestone countertops and limestone flooring. Companies install limestone tile and fireplaces too. Concrete companies use limestone to produce cement used in building foundations, roads, bridges, and other major construction projects.

You can purchase limestone in different forms and quantities such as limestone slabs or crushed limestone. Consider the following when purchasing limestone:

1. Determine which parts of your project may be finished with limestone.

2. Investigate limestone suppliers for the best deal.

3. Determine whether you need a specialist in limestone installation.

Determine what type of limestone is appropriate for your project

Interior decorators use limestone where durability is not important. Other stones, such as granite, may be more suitable for outdoor projects, however. If you expose limestone to acidic solutions, it will erode, so it may not be appropriate in areas that get acid rain or acidic runoff.

I recommend: The National Gardening Association provides a calculator for determining how much limestone you need. This website also discusses how acidic soils may determine what material you buy. Limestone in pellet form makes a fine soil treatment. Large soil treatment projects may require that you purchase your own pelletizing equipment from Mars Mineral, a 30-year leader in the business. Stone World, an on-line magazine, provides information to companies who routinely work with stone.

Find limestone suppliers that offer selection and service

Choose a limestone supplier based on the products they carry, delivery services they may offer, and warranties they offer. Many suppliers offer free samples so that you can be sure of color and texture before buying. Limestone prices vary depending on type, size, and quantity of stone selected.

I recommend: Stone Selection carries a wide variety of limestone colors for use in limestone tile and other applications. The company imports its stock from France. Marble Corporation of America carries limestone for indoor applications such as limestone counter tops. The Stone Foundation compiles a list of stone suppliers across the United States.

Hire professional limestone installers when warranted

Other than cement companies, construction companies make the most use of limestone. Some companies employ staff that are skilled enough to do their own work. Some applications may require a specialist in limestone installation.

I recommend: The Indiana Limestone Company offers a variety of limestone products. Their business centers around limestone and has a local limestone supply from nearby quarries. This company also cuts stones into decorative building fixtures. The American Limestone Company offers customized landscaping options built with limestone slabs or cut limestone.
