Frequently Asked Questions

Pavers are manufactured concrete units cut to uniform sizes, while natural stone uses quarried material with irregular shapes and color variation. Pavers cost less and install faster, but natural stone offers unique appearance and typically lasts longer. Your choice depends on budget, desired look, and how formal you want the space to feel.

Excavation depth determines base material thickness, which prevents settling and keeps the surface level. Without adequate excavation for proper base layers, pavers shift when ground freezes and thaws. Maine's freeze-thaw cycles require deeper excavation than southern climates to maintain a stable patio surface.

Repair works when only sections lean or individual blocks are damaged, but the wall's foundation remains stable. If the entire wall leans significantly, shows continuous cracking, or was built without proper drainage, replacement becomes necessary. Walls older than 20 years with multiple issues typically need rebuilding rather than repair.

Water pressure builds behind retaining walls without drainage, causing them to lean, crack, or fail completely. Proper drainage systems relieve this pressure and prevent soil saturation that weakens wall stability. Maine's heavy spring runoff and freeze-thaw cycles make drainage especially critical for wall longevity.

Water flowing across the surface carries gravel away, creating low spots that collect more water and worsen quickly. Poor crown or cross-slope prevents drainage, while lack of compaction allows gravel to shift under traffic. Seasonal frost heave in Maine accelerates the process by lifting and displacing material.

Soil must be loosened, leveled, and amended before laying sod so roots penetrate easily and establish quickly. Compacted or ungraded soil causes uneven surfaces, poor drainage, and weak root development. Proper preparation determines whether new sod thrives or develops bare spots within the first season.

Excavation exposes the foundation, then perforated pipe is placed at the footing level surrounded by gravel to collect groundwater. The system slopes to direct water away from the structure toward a discharge point. Proper installation keeps basements dry and prevents hydrostatic pressure from damaging foundation walls.

Replace when you notice recurring basement moisture, standing water near the foundation, or visible rust and sediment in discharge water. Systems older than 30 years often have collapsed pipes or roots blocking flow. If excavation reveals crushed pipes or no gravel around the drainage line, full replacement is needed.

Construction clearing removes everything to bare soil for building, including stumps and roots, with grading to final elevation. Trail clearing leaves root systems intact to prevent erosion and removes only brush and trees blocking the path. Equipment size and site access also differ significantly between the two approaches.

Tree density, size of material being removed, terrain slope, and site accessibility all impact pricing. Clearing dense hardwood forest costs more than removing brush and small growth. Disposal requirements, stump removal depth, and whether grading is needed after clearing also affect total project cost.

Freeze-thaw cycles cause water trapped under patios to expand and lift pavers, creating uneven surfaces. Maine requires deeper excavation, thicker gravel bases, and positive slope away from structures to prevent ice damage. Without proper drainage, spring thaw creates standing water and accelerates patio deterioration.

Equipment reshapes the surface to create proper crown and cross-slope for water runoff, filling low spots and removing high areas. Fresh gravel is added and compacted to restore a smooth driving surface. Regrading corrects drainage problems that cause washouts and extends the time between major driveway repairs.
