Lot Grading & Excavation
in Seguin, TX | Free On-Site Estimates!
San Marcos Elite Grading & Excavation has been grading & resloping lots in the Seguin, TX area for over 20 years! Seguin is the county seat of Guadalupe County and one of the most industrially significant small cities on the I-10 corridor between San Antonio and Houston, with a 2024 population of approximately 38,000 and a growth trajectory that has accelerated sharply as residential development follows the city's expanding manufacturing and logistics base. Caterpillar's engine-building plant — which announced a $90 million additional investment in 2024 — anchors a manufacturing concentration roughly four times the national average, drawing a workforce that has fueled sustained residential construction demand across the city's east and west sides along the I-10 frontage roads. The median household income in Seguin is $64,861, with higher-income residential development concentrated in newer subdivisions including the 415-acre Walnut Springs master-planned community, Mill Creek Crossing, Pecan Grove, and the established Peirson Park neighborhood. Seguin is situated along the Guadalupe River approximately 35 miles northeast of San Antonio and 15 miles east of New Braunfels, placing it within practical range of San Marcos Elite Grading & Excavation's Hays County service area. San Marcos Elite Grading & Excavation is a licensed, insured excavating contractor with 12+ years of Central Texas field experience and laser-guided equipment on every finish grade project.
Seguin sits within the humid subtropical climate zone, with average summer highs in the mid-90s°F and average winter lows in the upper 30s°F. The city's soil profile transitions between the blackland prairie clay that dominates the eastern Guadalupe County lowlands and the sandy loam and caliche soils found on higher ground north of the Guadalupe River. Annual rainfall totals approximately 32 to 35 inches, concentrated in spring and fall storm events that can produce significant runoff on both the flat clay-bearing lots common in Seguin's residential areas and the sloped terrain along the river corridor. New residential construction absorbing the workforce growth generated by Seguin's industrial base has produced consistent demand for site preparation, pad construction, and drainage correction services across the city's expanding development corridors.
San Marcos Elite Grading & Excavation carries full general liability insurance and coordinates permit applications with the City of Seguin and Guadalupe County offices on all permitted projects. All finish grade work is warranted against defects in workmanship for one year from project completion, with drainage systems carrying a two-year workmanship warranty.

Grading & Excavation Repair Services in Seguin
We provide drainage correction, lot resloping, and French drain installation across Seguin's established and developing neighborhoods. The city's combination of flat clay-bearing lots in residential areas and sloped terrain along the Guadalupe River corridor creates distinct drainage correction demand across different parts of the market.
Foundation Perimeter Drainage Correction
Residential lots in Seguin's established neighborhoods — including Peirson Park and the older blocks near the historic courthouse square along Court Street and Austin Street — sit on clay-bearing soils that accumulate water against foundation perimeters when lot grades are flat or negative. The Foundation Performance Association links inadequate site drainage to movement in over 60% of all Texas residential foundations, and the repair costs average $8,000 to $15,000 per incident according to Texas A&M AgriLife Extension. We correct foundation perimeter drainage through cut-and-fill resloping with laser-guided equipment, establishing the minimum 6-inch drop over the first 10 feet from the foundation required by the International Residential Code.
Drainage Correction in New Subdivisions
Newer subdivisions on Seguin's east and west sides along the I-10 frontage roads — including Mill Creek Crossing, Pecan Grove, and the developing Walnut Springs master-planned community — present drainage correction demand as original finish grades settle past the first five years of occupancy and landscaping alters original drainage patterns. We assess full lot drainage conditions during the site visit and design corrections that address the root cause rather than the visible symptom, including swale restoration, downspout integration, and outlet correction where drainage is not reaching the street or designated drainage easement.
French Drain Installation for Persistent Wet Areas
Properties in lower-lying sections of Seguin's residential areas — particularly lots near the Guadalupe River corridor, Walnut Branch, and the drainage ways feeding through the city's established neighborhoods — frequently experience subsurface water migration that surface regrading alone cannot correct. A properly engineered French drain system can reduce subsurface water pressure against a foundation by up to 90% according to University of Minnesota Extension data. We install perforated HDPE pipe systems bedded in clean washed gravel wrapped in geotextile filter fabric, with cleanout access points on every installation and outlets sized for reliable discharge under peak storm conditions.

Residential Site Preparation and House Pad Construction
New residential construction across Seguin's expanding development corridors — along FM 78, FM 1117, FM 2438, and the acreage parcels opening up in the communities of New Berlin and Geronimo east and north of the city — requires site preparation calibrated to the soil conditions and drainage characteristics of each project location. We build house pads to 95% standard Proctor compaction in 8-inch lifts, coordinate compaction testing with licensed geotechnical laboratories, and set pad elevations to provide positive drainage on all four sides — verified with laser grade checks before foundation forming begins. On lots in Seguin's clay-bearing residential areas, fill moisture conditioning is managed throughout pad construction to prevent the compaction failures that produce post-construction settlement on expansive clay sites.
Commercial and Industrial Site Preparation
Seguin's active industrial and commercial development along the I-10 corridor — driven by Caterpillar's ongoing expansion, the $25 million retail development underway along the I-10 frontage road, and the broader manufacturing concentration in Guadalupe County — generates consistent demand for commercial site preparation services that exceed residential scale. We execute commercial earthwork scopes with hydraulic excavators in the 20- to 45-ton class, coordinating directly with civil engineers on grade plan compliance, stormwater management integration, and inspection scheduling.
Driveway Grading and Culvert Installation
Rural properties in Guadalupe County surrounding Seguin — in New Berlin, Geronimo, Kingsbury, and along the county roads feeding into the city's ETJ — frequently require culvert installation to maintain drainage continuity at driveway crossings on county road frontages. Guadalupe County road rules require culvert permits for driveways on county road frontages. We size and install culverts to meet or exceed county requirements, coordinate permit applications with the applicable county offices, and grade driveway pads to consistent cross-slope with laser-controlled equipment.
