Excavations in Sioux Falls

What Excavations actually involves

When water is finding its way into a Sioux Falls basement through the foundation wall itself, rather than through a window well or a cracked slab you can see, the fix usually isn’t inside the house. It’s outside, below grade, where a failed waterproofing membrane, a collapsed drain tile, or years of soil settlement have opened a path for groundwater. Excavation work means digging down to the footing, exposing the problem, and correcting it at the source instead of chasing the symptom every spring.

This typically means removing soil in sections along the affected wall, sometimes down 6 to 8 feet depending on footing depth, using mini-excavators or hand digging in tight side yards where equipment access is limited. Once the wall is exposed, the crew can see exactly what’s failing: cracked or missing membrane, a crushed clay tile drain (common in Sioux Falls homes built before the 1970s), or a sewer or water lateral that’s settled and separated at a joint. The scope and depth depend entirely on what’s found, which is why this work starts with diagnosis, not digging.

Our process

1. Locate underground utilities. Before any digging starts, gas, water, sewer, and electrical lines are marked through South Dakota One Call. Skipping this step is how excavation jobs turn into utility outage claims.
2. Diagnose the entry point. Moisture meters, borescope cameras run through drain tile access points, and grading observation help confirm whether the issue is a membrane failure, a broken drain tile, or a lateral line problem before a shovel goes into the ground.
3. Excavate to the footing. Soil is removed in controlled sections, not the whole yard at once, to limit disruption and keep the excavation stable and safe to work in.
4. Repair or replace the failure point. This might mean applying a new waterproofing membrane, replacing crushed drain tile with modern perforated pipe, or repairing a settled sewer or water line joint.
5. Backfill and compact in lifts. Soil goes back in layers, compacted as it goes, so it doesn’t settle unevenly again in six months and reopen the same crack.

What separates a good excavation response from a bad one

The most common mistake is treating excavation as a demolition job instead of a diagnostic one. A crew that digs first and figures out the problem second often ends up over-excavating, damaging landscaping or hardscape that didn’t need to move, or missing the actual failure point entirely because they patched the first crack they saw instead of tracing water back to its real source.

Insurance adjusters reviewing an excavation claim generally want to see the same things a careful contractor should already be documenting: photos of the exposed footing and failure point before repair, confirmation of utility locates, and a clear explanation of why the excavation was necessary rather than cosmetic. Compaction matters too. Soil backfilled without proper lift compaction settles unevenly, which shows up later as new cracks in a driveway, patio, or the foundation itself, sometimes within the first freeze-thaw cycle.

What does Excavations cost?

Excavation pricing depends heavily on depth, soil conditions, access (a fenced backyard with mature trees costs more to dig than an open side yard), and what’s actually found once the wall is exposed. Typical industry costs for Sioux Falls area excavation work run in the ranges below, though every property is different. Crew Restoration & Construction provides a written scope of work with defined depth, linear footage, and repair method before any excavation begins.

Homeowners insurance typically covers excavation when it’s required to access and repair sudden, accidental water damage, such as a burst pipe or a sudden drain tile failure, but it generally does not cover excavation tied to gradual seepage, poor original grading, or normal foundation settlement, so coverage should be confirmed with your carrier before work starts.

Seasonal & regional considerations

Sioux Falls sits on clay-heavy soil that expands when wet and contracts hard in a dry summer, which is part of why foundation and drain tile failures show up here more than in sandier soil regions. Spring is the busiest season for this kind of excavation, once frost is out of the ground and snowmelt or spring rain finds every weak point in a foundation wall. Digging during a hard freeze is possible but slower and more limited, since frozen soil at the surface has to be broken through before excavation can proceed.

Service area

Crew Restoration & Construction performs excavation work at homes and commercial properties throughout Sioux Falls and surrounding communities including Brandon, Tea, Harrisburg, and Brandon. Older neighborhoods with clay tile drain systems and homes built on Sioux Falls’ heavier clay soils tend to be the most common candidates for this kind of below-grade work.

If water is tracking down a basement wall every time it rains, or a sewer line keeps backing up in the same spot, an excavation may be what finally stops it for good. Call (605) 965-2727 to schedule a diagnostic assessment and get a written excavation scope before anything is dug.
