Frequently Asked Questions

Grading creates slope that directs water away from foundations before it can pool or seep into basements. Missouri's clay-heavy soil absorbs water slowly, so surface runoff must move away from structures quickly. A 2% minimum slope in the first 10 feet prevents hydrostatic pressure against foundation walls.

Gas lines typically require 18-24 inch depth, while water lines need 30-36 inches to stay below frost line in south-central Missouri. Electrical conduit depth varies by voltage and local code. Depth control matters because shallow lines risk freeze damage and code violations that delay inspections.

Grading fixes the problem when gravel migrates to edges, ruts form in wheel paths, or water pools instead of draining. Adding gravel over poor grade just repeats the cycle. Proper grading establishes crown and slope so new gravel stays in place and water sheds correctly.

Forestry mulching grinds vegetation into mulch that stays on-site, while traditional clearing requires hauling debris away. Mulching works faster on brush and small trees, leaves no burn piles, and the ground cover reduces erosion. It's ideal for creating access paths or clearing overgrown fence lines without disturbing topsoil.

Most failures happen because fabric wasn't used, wrong gravel was chosen, or the drain slope is insufficient. Clay soil in Missouri clogs perforations quickly without proper fabric wrap. Drains need consistent 1% slope minimum and clean rock—pea gravel doesn't provide enough void space for water flow.

Visible gullies, exposed tree roots, sediment washing onto driveways, or bare soil patches indicate active erosion. Properties on slopes or with poor vegetation cover erode faster during Missouri's heavy spring rains. Erosion near structures threatens foundation stability and creates drainage problems that worsen over time.

Ground must be excavated to proper depth, compacted, and leveled to support the slab without settling. A gravel base provides drainage and stability—thickness depends on soil type and slab use. Proper base prep prevents cracking from uneven settling and water accumulation under the concrete.

South-central Missouri has limestone bedrock close to the surface in many areas, especially on ridge tops and hillsides. Valleys and creek bottoms typically have deeper soil. Pre-trenching evaluation identifies likely rock depth based on terrain, but bedrock encounters sometimes require alternative routing or specialized equipment.

Water flows away from structures instead of pooling, soggy areas dry out faster after rain, and erosion slows in previously channeled areas. You'll notice water following new paths during storms and previously wet zones becoming usable. Grass grows better once standing water no longer drowns root systems.

Footings must reach undisturbed soil and sit below frost line to prevent heaving and settling. In Missouri, frost depth is typically 30 inches, so footings go deeper in most builds. Shallow footings shift when ground freezes, causing cracks in walls and structural movement that worsens each winter cycle.

Site clearing removes vegetation and obstacles, excavation digs to planned depth and footprint, and grading levels the base to eliminate high and low spots. Proper compaction follows to prevent settling under foundation weight. The process creates stable, level ground that meets engineering specs and allows accurate foundation layout.

Soil is cut from high areas and moved to fill low areas, creating level building pads on slopes without importing material. The process balances earthwork to minimize hauling costs while achieving required grades. Proper compaction of fill areas prevents future settling that could damage structures built on the pad.
