Foundation Repair in Irmo, SC

Seeing cracks, settlement, or moisture?

Quick answerIrmo sits on the Piedmont side of the Fall Line, where red clay is common. The USDA soil survey maps Cecil soil at the town center. It is well drained and mostly kaolinitic clay, so its shrink and swell rating is low. Water and slope cause more trouble than swelling. Runoff erodes soil beside footings. A site visit shows what your lot needs.

Foundation Help in Irmo, SC

Irmo straddles Richland and Lexington counties, and many lots run down toward Lake Murray and its creeks. The USDA soil survey maps Cecil fine sandy loam at the town center. Cecil is a red clay soil with about 4 percent slope in the mapped area.

Most of this clay is kaolinitic, which the soil survey rates low for shrink and swell. The bigger risks are slope, runoff, and soft wet soil. Foundation Pros of Columbia looks at how water moves across your lot as well as the foundation itself.

What the Ground Looks Like in Irmo

Cecil is well drained, but the clay can soften and slip when saturated. Weathered rock under the clay can be shallow or deep, so pier depth can change across a lot.

Look up your address in the USDA Web Soil Survey. Soil can change from one side of a lot to the other, so we also read the ground on site. The map covers Richland and Lexington counties.

Our 5-Step Foundation Repair Process in Irmo

Every foundation repair in Irmo follows the same five steps. The details change with your home and your lot.

InspectionWe check slope, runoff, and erosion beside the footings. We look at how water moves across your lot. We measure and photograph what we find.
ExcavationWe dig small access holes at the pier locations next to the foundation.
UnderpinningWeathered rock can be shallow or deep here, so pier depth can change across a lot. We install steel push piers or helical piers down to stable soil. We then connect them to steel brackets under the footing so they carry the load.
BackfillWe fill and compact the holes. We restore the area as closely as we can.
Final QAWe check the work, review it with you, and answer your questions.

Not every home needs piers. After the inspection, we explain whether piers or another fix fits your home. See the full foundation repair and piering process in Columbia, SC.

Foundation Questions in Irmo, SC

What causes foundation problems in Irmo, SC?

Water and slope. Runoff erodes soil next to footings. Wet red clay can soften and press on walls. Mature tree roots and poor drainage can add stress.

Is Irmo clay expansive?

Mostly not. The soil survey rates the Cecil soil mapped at the town center as low for shrink and swell. Water, slope, and erosion cause more trouble than swelling.

Do Irmo homes near Lake Murray have special risks?

Lots near the lake often slope. Sloped lots send runoff toward the house. Good gutters and grading matter a lot.
