When working with concrete, hydrostatic pressure plays a big role. But what is hydrostatic pressure?
Hydrostatic pressure (water=hydro, static=resting) is the level of pressure that standing water creates. This pressure can press onto the walls of its container, whatever that may be. Concrete, although it seems very solid when dry, is susceptible to moisture and acts as a “container” of sorts. When water vapor is present inside concrete, pressure can begin to build. Over time, this pressure can affect the strength and integrity of the concrete.
During the initial pouring process, contractors mix concrete with water. As the concrete cures and dries, much of the water evaporates. This process leaves behind millions of tiny channels and pores inside the concrete.
Even after the concrete dries, these channels can fill with water again. Excess moisture, flooding, groundwater, or other sources can introduce moisture back into the concrete. As moisture builds inside these spaces, hydrostatic pressure can increase.
There are plenty of things that flooring contractors, inspectors, and installers need to know before taking on the assignment of flooring and new customers. When experience and training are present, the customers will be satisfied with a job well done. Without them, there will be plenty of room for customer complaints.
