Frequently Asked Questions

  • What does an excavation contractor actually do?

    An excavation contractor prepares land for construction by digging, grading, and moving earth. This includes site clearing, foundation prep, trenching for drainage, and rough grading. Proper excavation ensures stable ground conditions before any hardscaping or building work begins.
  • How is forestry mulching different from traditional land clearing?

    Forestry mulching grinds trees, brush, and stumps into mulch on-site in a single pass, eliminating hauling costs and leaving nutrients in the soil. Traditional clearing removes and trucks away debris. Mulching is faster, less disruptive to the soil, and more environmentally sustainable.
  • When should you install hardscaping versus planting landscaping first?

    Hardscaping — patios, retaining walls, walkways — should be installed before planting. Hardscape installation involves heavy equipment that can damage plants and compact soil. Completing structural elements first protects your landscape investment and ensures proper drainage is established before softscape work begins.
  • What factors drive the cost of an excavation project?

    Key cost drivers include soil type, site accessibility, depth of dig, rock presence, and debris disposal requirements. Drainage complexity and total volume of material to move also affect pricing. Sites with ledge rock or poor access typically require more equipment time and specialized tools.
  • Can forestry mulching be used on steep or wooded terrain?

    Yes — forestry mulching equipment is well-suited for slopes and densely wooded areas where conventional clearing equipment struggles. The mulching head processes vegetation in place, reducing erosion risk on steep grades and avoiding the need to drag debris across sensitive terrain.
  • How do you prepare land in Maine before winter sets in?

    Late-season prep should include final grading to direct runoff away from structures, seeding disturbed areas to prevent erosion, and securing any exposed soil. Drainage swales should be cleared of debris before freeze-up, and bulk material like road salt should be stocked ahead of the first storm.
  • What's the difference between a retaining wall and a garden wall?

    A retaining wall is an engineered hardscape structure designed to hold back soil and manage grade changes — it must handle significant lateral pressure. A garden wall is primarily decorative with minimal structural load. Retaining walls require proper drainage behind them to prevent pressure buildup and failure.
  • Do skid steers cause damage to existing lawn or landscaping?

    Tracked skid steers distribute weight more evenly and cause less turf damage than wheeled equipment, but some surface disturbance is normal on soft ground. Experienced operators minimize impact by choosing appropriate equipment for site conditions and avoiding repeated passes over the same areas.
  • Why does proper drainage matter for landscaping projects?

    Poor drainage causes erosion, kills plants, undermines hardscape foundations, and can direct water toward structures. Grading and drainage planning before landscaping installation protects the entire investment. In Central Maine's freeze-thaw climate, standing water that ices over can also shift pavers and retaining walls.
  • How soon after land clearing can landscaping begin?

    Timing depends on soil conditions and what was cleared. After forestry mulching, the mulched layer should be graded and settled before planting. If stumps and roots were ground out, soil may need to be amended and compacted first. Generally, light landscaping can begin within a few weeks of clearing completion.
  • What affects the cost of a land improvement project in central Maine?

    Site access, existing conditions like ledge or wet soil, and seasonal timing drive cost variation. Projects requiring ledge removal or extensive drainage work require more specialized equipment and time. Dense woods and steep grades also increase clearing and prep complexity, especially on properties without existing access roads.
  • How far outside Augusta does R.A. Robinson Land Improvements travel for projects?

    Service extends throughout central Maine including Manchester, Gardiner, Winthrop, Waterville, and Hallowell. Travel distance can affect scheduling flexibility during peak season. Remote sites with challenging access may require additional mobilization time for tracked equipment.
  • Why does grading and drainage matter for hardscaping that looks fine when it's finished?

    Improper grading causes freeze-thaw heaving that shifts pavers and cracks retaining walls within two winters. Water trapped behind walls or under patios accelerates structural failure. Proper subsurface prep and drainage routing aren't visible but determine whether hardscaping lasts five years or twenty.
  • What should a site visit for excavation or land clearing cover before you get a quote?

    Soil conditions, drainage patterns, existing utilities, property access for equipment, and what stays versus what's removed. Ledge, wetlands, or underground obstacles found during assessment prevent surprise costs. Any estimate given without walking the site should be treated as a rough guess, not a firm number.
  • When should you clear land versus when should you wait to landscape after clearing?

    Clearing during frozen ground minimizes rutting and allows equipment access on otherwise soft terrain. Planting and finish grading happen after soil settles and drainage is confirmed working. Sequencing decisions depend on project timeline, seasonal weather windows, and whether you're building or landscaping first.
  • What's the advantage of forestry mulching over traditional clearing and hauling?

    Trees and brush are ground into mulch on-site, eliminating trucking costs and disposal fees while leaving erosion-controlling organic material in place. This approach works on steep or densely wooded terrain where traditional clearing would require extensive access roads. The mulch layer also suppresses regrowth and prepares the site for seeding.
  • Does Maine's freeze-thaw cycle change how drainage projects need to be designed?

    Drainage systems must account for frost heave and ice dams that shift grade and block flow. Shallow trenches or undersized swales fail when frozen ground prevents infiltration and spring melt overwhelms capacity. Proper depth, slope, and outlet placement prevent winter ice buildup from redirecting runoff toward foundations.
  • What should you prepare before a skid steer or excavation crew arrives?

    Mark underground utilities, remove obstacles like yard furniture or decorations, and flag trees or landscape features you want protected. Clear communication about access routes and staging areas prevents turf damage. Confirm where excavated material will be stockpiled or if it needs hauling off-site.
  • Why do land improvement projects get scheduled differently in late season?

    Late-season work focuses on erosion control, final grading, and drainage clearing to protect properties before freeze-up. Planting and hardscaping often pause until spring when ground thaws and materials can be properly compacted. Seasonal prep done in fall prevents spring washouts and allows earlier project starts the following year.
  • What's the difference between rough grading and finish grading, and why does it matter?

    Rough grading establishes drainage flow and general contours after excavation or clearing. Finish grading creates the final surface for planting, hardscaping, or lawn installation and requires settled soil. Skipping rough grading or rushing finish work before the site settles leads to low spots, erosion channels, and standing water.
  • What should a written estimate for excavation or site work include that protects you from surprise costs?

    Scope of clearing or excavation, material quantities, disposal or hauling fees, and allowances for unknown conditions like ledge or wet soil. Line items should separate fixed costs from contingencies. Estimates that lump everything into one number make it impossible to verify what changed if the final invoice increases.
