Patio settling
Back patios can settle where new-home backfill consolidates or irrigation repeatedly wets the slab edge.
Patio, sidewalk, and foundation settlement starts below the concrete. Poly Flow tests the soil and support conditions before recommending a repair.
Star sits along the lower Boise River valley where river terraces meet expanding residential development.
Layered sand, gravel, silt, and loam are common regional materials, with additional variability from former agricultural use and subdivision grading.

Back patios can settle where new-home backfill consolidates or irrigation repeatedly wets the slab edge.
Sidewalk panels may drop over utility crossings or where landscape watering reaches incompletely compacted base material.
Uneven moisture around the perimeter can affect support differently from one side of a home to the other, making soil testing useful before choosing a repair.
Regional geology provides context, but the repair decision depends on what is happening at the property. These are the questions that connect the local setting to an individual diagnosis.
Check irrigation and roof discharge along slab edges where expanding development meets lower river-valley terrain.
Measure the affected Star slab against doors, walls, curbs, drains, and neighboring panels to distinguish settlement from an original slope.
Test utility crossings and newer foundation backfill separately from older native or agricultural ground.
Record wall cracks, binding doors or windows, floor slope, and separation at porches or stem walls. Structural symptoms should not be diagnosed from a nearby patio alone.

This is a common issue on new construction with basement foundations. After forming and pouring the basement walls, excavation spoils are backfilled against the foundation. I…
Read the projectStar sits along the lower Boise River valley where river terraces meet expanding residential development. That local setting can affect where water travels, how fill consolidates, and whether settlement is limited to one slab or reaches deeper support. Poly Flow starts with testing, then recommends the service that addresses the measured condition.
For Star patios and sidewalks, lifting can restore settled slabs when the concrete is sound and the weak support is shallow enough to treat. Back patios can settle where new-home backfill consolidates or irrigation repeatedly wets the slab edge.
Explore concrete liftingFoundation symptoms need a deeper evaluation than an uneven patio or walkway. In Star, uneven moisture around the perimeter can affect support differently from one side of a home to the other, making soil testing useful before choosing a repair.
Explore foundation repairOpen joints and cracks give runoff, snowmelt, or irrigation a path beneath residential concrete. Sealing appropriate openings can help protect repaired support from continuing water entry in Star.
Explore crack & joint sealingWhen testing finds deeper weak zones or voids, lifting the surface alone may not address the cause. Layered sand, gravel, silt, and loam are common regional materials, with additional variability from former agricultural use and subdivision grading.
Explore soil stabilizationA low patio edge, uneven sidewalk, or foundation symptom can have several causes. Poly Flow checks the site and measures the soil so the recommendation matches the depth of the problem.
Back patios can settle where new-home backfill consolidates or irrigation repeatedly wets the slab edge. The condition can be highly localized, so the surrounding grade, downspouts, irrigation, and support beneath the slab should be checked before selecting a repair.
Sidewalk panels may drop over utility crossings or where landscape watering reaches incompletely compacted base material. If the panel is still structurally sound, polyurethane lifting may restore the elevation without demolition. Cracked or badly deteriorated concrete may need a different approach.
Star sits along the lower Boise River valley where river terraces meet expanding residential development. Uneven moisture around the perimeter can affect support differently from one side of a home to the other, making soil testing useful before choosing a repair. Soil-resistance readings help distinguish a shallow slab problem from movement that reaches a footing or deeper support layer.
Layered sand, gravel, silt, and loam are common regional materials, with additional variability from former agricultural use and subdivision grading. A single property can include native soil, utility trenches, foundation backfill, imported base, and other disturbed material, so broad regional soil descriptions cannot replace on-site testing.
Sound patios and sidewalk panels may be candidates for concrete lifting. Open water paths may also need crack and joint sealing. Deeper weak soil can call for stabilization, while structural movement may require foundation repair. Poly Flow tests first so the recommendation matches the problem.
