Stop Washouts Cold: Engineered Erosion Control

Erosion Control — Stop Washouts, Protect Soils, Keep Water Where It Belongs

Stabilization strategies that work in real-world Missouri weather

Unchecked runoff chews ruts into driveways, clogs culverts with sediment, undercuts banks, and sends topsoil downstream. Mr. G’s provides erosion control services that combine smart grading, durable armoring, and vegetative stabilization so your property holds together through spring downpours and freeze–thaw cycles. We diagnose the cause (velocity, concentration, poor outlets, bare soils), design the fix (slowing, spreading, strengthening), and install the right mix of materials—so your ditches, slopes, and channels perform instead of failing after the first big storm.

What our erosion control work includes

• Slope regrading & shaping: Reduce slope angles, remove over-steep sections, and create terraces or benches where necessary to slow flow.
• Energy dissipation & outlets: Riprap aprons, plunge pools, or level spreaders at pipe and swale outlets to knock down velocity before water hits bare soil.
• Rock armoring (riprap): Properly sized stone on geotextile in channels, at bends, and on steep sections to resist shear and prevent undercutting.
• Check structures: Rock checks or wattles in ditches and swales to step down grade, reduce velocity, and capture sediment.
• Erosion control blankets (ECBs): Straw/coconut or synthetic blankets pinned to slopes for immediate surface protection and seed germination support.
• Hydroseed & seeding: Seed mixes matched to sun/shade and expected traffic, with tackifier or mulch cover for quick establishment.
• Soil lifts & bioengineering: Coir logs, live stakes, and reinforced soil lifts for sensitive banks and near-water applications.
• Sediment controls: Silt fence, inlet protection, and temporary basins during construction phases to keep soils on site.
• Culvert and ditch rehab: Regrade ditch lines, reset or upsize culverts, and stabilize inlets/outlets to handle design flows.

Why erosion control is a system, not just a product

Erosion is driven by velocity × volume × exposure. Throwing rock at a problem point may fail if upstream grades are too steep or if outlets blast water into bare soil. We design the whole path: collect water, slow it, spread it, then discharge it onto stabilized ground. That means aligning grading, drainage, and armoring—so each component reinforces the next and the system survives real storm energy.

Our step-by-step erosion control process

1. Site assessment & flow mapping
   We walk the property after rain if possible, trace rills and gullies to their sources, shoot key elevations, and evaluate soils and vegetation. We note culvert sizes, pipe slopes, and failure points (scour, undercut, blowouts).
2. Design the fix
   We choose the simplest durable solution: reshape grades to reduce energy, add checks to step down channels, armor critical sections, and specify blankets/seed for coverage. Culverts may be resized or reset to correct slopes and cover.
3. Access & protection
   Install stabilized entrances, limit disturbed areas, and set temporary silt controls so new work doesn’t create new problems.
4. Earthwork & shaping
   Regrade slopes, cut swales with stable side slopes, re-establish ditch geometry, and prepare subgrade for blankets or stone.
5. Armoring & structures
   Place geotextile, then riprap to the specified gradation; build rock checks at intervals; set coir logs or wattles to intercept sheet flow; install outlet aprons or level spreaders.
6. Vegetative stabilization
   Seed with region-appropriate mixes, hydroseed where coverage is challenging, and pin ECBs to hold seed and soil during establishment.
7. Tie-ins & finishing
   Blend improvements into existing grades, address driveway edges and culvert shoulders, and ensure no new low spots collect water.
8. Punch list, documentation & maintenance plan
   Verify flows, photograph critical details, and provide a simple care plan so vegetation and structures keep working.

Materials and methods chosen for performance

• Non-woven and woven geotextiles to separate soil from stone and prevent undermining.
• Riprap gradations sized to expected velocity and channel slope, installed to thickness with correct toe-in.
• Coir/biodegradable ECBs for green slopes, TRMs (turf-reinforcement mats) for higher-energy channels needing long-term synthetic support.
• Native or adapted seed blends for deep rooting, erosion resistance, and low maintenance once established.
• HDPE/PVC pipe and properly sized culverts installed with compacted bedding and protected outlets.

Typical erosion control problems we solve

• Ditches that cut deeper after each storm and fill downstream culverts with sediment
• Driveway culvert inlets that scour and undercut the driveway
• Banks sloughing into ponds or creeks
• Bare construction slopes that won’t hold seed
• Channel bends that blow out during peak flow
• Steep backyard slopes feeding muddy washouts onto patios and walks

Why choose Mr. G’s for erosion control

• Cause-first diagnosis: We fix the upstream issue, not just the symptom.
• Integrated site work: Grading, drainage, and erosion solutions installed by one accountable team.
• Right-sized protections: We match blanket types, stone sizes, and check spacing to real velocities and slopes.
• Clean execution: Defined haul routes, limited disturbance, tidy finishes, and photo documentation.
• Clear estimates: Scope, materials, and maintenance expectations laid out up front.

Maintenance that keeps protections working

• Inspect after every 1"+ rain for the first season; repair displaced rock, re-pin blankets, and touch up seed.
• Keep ditches open; clear leaves and sediment from checks, inlets, and outlets before and after storms.
• Mow high (3–4") on stabilized slopes; avoid scalping which exposes soil.
• Top up riprap if settlement reveals fabric or if velocity increases after upstream changes.
• Reseed bare spots promptly so coverage remains continuous.

FAQs: Erosion Control

Do I need riprap, or will blankets and seed be enough?

It depends on velocity and concentration. On gentle slopes with dispersed sheet flow, ECBs and seed often suffice. In ditches, at outlets, or on steep sections where water is concentrated and fast, riprap over geotextile (or a TRM system) is typically required.

My culvert keeps plugging with gravel and leaves—what’s the fix?

Often the inlet is too low, misaligned, or undersized, and the ditch geometry accelerates sediment toward it. We reshape the ditch, add rock checks upstream to drop sediment, and reset or upsize the culvert with a stable riprap apron so flow enters and exits without scouring.

How long do erosion blankets need to stay in place?

Most biodegradable ECBs are designed to last through the establishment window (one to two growing seasons). We recommend leaving blankets until turf is dense and roots knit the soil. On higher-energy channels, a turf-reinforcement mat may be permanent.
