Piling Foundation Overview

What is Piling?

Piling is the process of drilling foundations through to the underground to obtain more structural strength to the weak soil beneath. The process of piling prepares the ground to support the weight of the structure above. Foundation piling services can support structures such as a new home, road, or commercial building.

Piling foundation strategies will depend on several factors:

  • The type of building in question,

  • The condition of the soil,

  • and the type of foundation your structure has


While there are many different foundation materials available to use, pilings are the most common. For more information on what is foundation piling, please take a look at our article here.

Overview of Foundation Pilings

  • Pilings vs Piers: Pilings are a crucial aspect of foundation repair and construction. To compare, piling foundation installation works the same way that piers do with pier and beam foundation. However, there are a few differences to note when it comes to piers and pilings. For example, piers are commonly manufactured from materials like wood, brick, or concrete. By contrast, pilings are made from concrete and steel to ensure maximum strength of the structure it's supporting. Pilings and piers are also constructed a bit differently. Specifically, the team at Radtke Contractors constructs piers on-site, however we construct pilings off-site.

  • Piling Configurations: In addition, pilings come in a number of different configurations. We use concrete pilings the most (these are cylindrical in shape.) Another common configuration for pilings is steel. Steel pilings can be found as either cylindrical, square, or H-and X-shapes. Lastly, depending on the project, hollow pilings, while hollow, are often filled with concrete to improve their strength.

  • Piling Installation: Piling size is determined ultimately by the size of space that's available. Typically, our team will drive larger pilings utilizing diesel hammers or pile drivers, although static installation is preferred for foundation repair applications. In cases like these, we approach this by installing the piles in small sections, via a jack. The deeper the pilings are driven into the ground, the sooner they'll reach soil that is stable, which is known as the point of refusal, (which describes whether the soil can support the weight of the structure above.)

Foundation Piling FAQs

What is piling foundation?

A pile foundation is needed whenever the soil on a site is weak and needs the support of an underground structure. Piles are commonly manufactured from strong materials like concrete and steel. A piling installation is driven into the foundation until it reaches more stable soil, or "the point of refusal." At this point, the piling foundation can support the weight of a building or structure above.

How long do foundation pilings last?

Quality concrete and steel pilings will last you the lifetime of the structure itself. If you're investing in a professional foundation piling service, you'll want to choose a reputable company and also quality foundation pilings.

How much does a piling foundation cost?

The cost of a piling foundation service may vary depending on the type of material used, as well as the size of the project. For specifics, please contact the Radtke team at (920) 582-4114.
