Flatwork includes all concrete work located along a horizontal plane. This includes indoors projects like floors or concrete stairs, as well as outdoor elements like patios, sidewalks, and driveways. Concrete flatwork does not refer to vertical structures like walls or bridges.

Flatwork – such as caulking joints in sidewalks – helps stop weed growth. It can also keep water from coming into the foundation. Concrete flatwork may also include repair or maintenance work to fix existing concrete surfaces. Over time, concrete walkways or floors can develop chips or cracks, which are not only unsightly, but also a threat to the integrity of the structure. For minor cracks, contractors inject the crack or void with special concrete caulk, or fill it with a simple patching compound. Major repairs may require that the concrete is broken out and replaced with new, reinforced flatwork. Damaged surfaces may also be coated with a thin top layer of concrete to refinish the surface.

Despite its name, concrete flatwork does not have to feature a boring, flat finish. Many modern applications are highly textured, with special patterns and colors used to give the concrete a pleasing look. For example, stamps or molds can be used to give concrete patios the look of traditional brick or stone. Even specialty trowel work can add swirls or other designs to a paved structure.

Joint sealant and joint repair is an important part of any commercial building, facility or installation. They are designed to join two different materials or surfaces, and control wind, water, moisture and debris entry or accumulation.

At Hawthorne Construction, we have years of experience in joint sealants/caulking and joint systems, and we know exactly which method and material to apply. In some cases, you need a flexible joint with some give, while at other times something more firm and solid is required to resist damage. We will assess your commercial sealant installation and propose the best solution every time.

As a trusted name in joint sealants/caulking and joint systems based in Central City, Iowa and serving all of eastern Iowa, Hawthorne Construction will take care of the three major areas of joining:

Commercial Joint Sealants

Many industrial facilities and installations must adhere to specific requirements and rules concerning joint sealants and caulking, and need to be treated with extra care and safety to ensure compliance with regulations. We always stand behind our work, and strive to make our customers happy.

Commercial Expansion Joint Repair

Expansion joints allow expansion and contraction between two different surfaces or materials. This obviously puts a large degree of stress on the joint, especially in large, heavy-duty commercial applications.

That’s when a quick repair turns into a major one.
