One of the most significant threats to a building’s safety is a weak foundation. That’s why many business owners and property managers turn to pressure grouting. Here’s what you should know about this popular form of foundation repair. 

What Is Pressure Grouting? 

Pressure grouting is a construction technique that improves a foundation’s stability. To begin, workers insert a steel pipe about 10 to 20 feet below the ground (the actual depth depends on factors such as the building’s size and the soil’s condition). They then use the pipe to pump a cement-based grout into the foundation. The workers will first pump the mixture at the lowest elevation, allow it to set, and then raise the pipe slightly to pump the grout at the next elevation.

This process is repeated until every level of the foundation has been pumped with grout. At each level, the grout fills in any voids or weak spots and pushes the soil upward, making the foundation more stable and strong.

When Is It Necessary? 

As one of the most common types of foundation repair, pressure grouting is used to fix voids, cracks, and fissures, all of which threaten a building’s structural safety. The technique is also regularly used to fix sinkholes. Sinkholes appear when water loosens the soil beneath a building, usually due to heavy rains or new drainage patterns.  

Pressure grouting can also be used as a preventative measure. For instance, builders may use it to strengthen soil before laying a foundation and significantly reduce the risk of structural issues such as settlement. Moreover, because the grout decreases water flow under a building, the technique can be used to prevent water damage.
