Pit Sand, Lakefront Grade, and Old Village Concrete
The Platte valley ground under most of Valley is sand and gravel, which is a good base and a fast-draining one. That solves the problem clay causes — you are not fighting soil that swells in April and shrinks in August — but it introduces its own. Granular soil is only as stable as the water moving through it. A downspout discharging beside a slab edge, a sump line running along a driveway, or a lakeside lot where runoff channels toward the water will move sand out from under concrete, and the slab finds out about it a season later.
Lakefront lots add grade. When a property falls toward the water, everything about the flatwork is a drainage decision: which way the patio sheds, whether a walkway needs to be stepped rather than ramped, whether a retaining element is doing structural work or just holding mulch. Stepped systems here need footings below frost depth — around forty-two inches in this area — or they will heave a little each winter until the treads are uneven. That footing depth is not somewhere to save money.
Back in the older village core the problems are the ones you would expect from concrete poured in the 1940s and 50s: three inches, no reinforcement, no air entrainment, laid on native soil. Seventy Nebraska winters and decades of deicer produce a surface gone sandy, edges that crumble when you kick them, and cracking across whole panels. Those are replacements, not repairs, and the value of doing it now is that the new slab gets a compacted base, reinforcement, and an air-entrained mix that will not repeat the story.
Valley also took water in 2019, particularly on the low ground toward the river. Same principle as elsewhere in the valley: ground that was saturated and has dried is not necessarily where it started, and before we pour on it we want to know whether it has settled out. Over-excavating and bringing in engineered base costs something and it is frequently the right call.
What we pour in Valley
- Driveways, replacements, and widening strips
- Patios, walkways, and outdoor living slabs
- Front steps, stoops, and porch slabs on proper footings
- Garage, shop, and outbuilding floors
- RV, boat, shed, and equipment pads
- Repair, resurfacing, slab lifting, and removal
