Frequently Asked Questions

Certified Irrigators hold TCEQ licensing that requires testing on backflow prevention, hydraulic design, and water conservation practices. This training ensures systems meet state regulations and avoid costly cross-connection violations. Licensed professionals design zoning that prevents runoff and matches precipitation rates to soil absorption capacity in Central Texas clay.

Central Texas experiences extreme heat, irregular rainfall, and clay soil that drains poorly when saturated but cracks when dry. Effective systems use separate zones for turf versus shrub beds since water needs differ drastically. Controllers with rain sensors and seasonal adjustments prevent overwatering during brief humid periods while maintaining coverage through extended dry spells.

Heads sink as soil settles, shrubs grow and block spray patterns, or pressure drops when zones contain too many heads. Clay soil in Central Texas shifts dramatically between wet and dry seasons, changing head alignment. Leaks in lateral lines reduce pressure across entire zones, leaving dry spots even when runtimes increase.

Sod establishes immediately, tolerates foot traffic within weeks, and prevents erosion on slopes where seed would wash away. It's ideal when irrigation is already installed or when lawn appearance matters quickly for home sales or events. Seed requires 60-90 days of restricted use and consistent moisture that's difficult to maintain during Central Texas heat.

Remove existing dead grass, weeds, and debris, then loosen compacted clay to 4-6 inches deep. Grading corrects drainage issues so water flows away from foundations. Soil amendments improve root penetration in heavy clay, and proper leveling prevents low spots where water pools and creates disease pressure after installation.

Inspections check coverage uniformity, measure pressure at heads, test valve operation, examine backflow devices, and run each zone to identify leaks or broken components. Controllers are evaluated for programming errors and seasonal adjustment settings. The inspection reveals whether zones apply water faster than clay soil absorbs it, causing runoff.

Mulch breaks down and needs replenishing to suppress weeds and regulate soil temperature. Plants grow beyond their intended spacing and require thinning or pruning to maintain design structure. Edging deteriorates, allowing turf to invade beds. Seasonal color rotations replace spent annuals to preserve visual interest year-round.

Clay expands significantly when wet and shrinks when dry, creating lateral pressure that destabilizes walls without proper drainage. Retaining walls need gravel backfill and weep holes to relieve hydrostatic pressure during heavy rain. Base preparation and material selection must account for this soil movement to prevent cracking or leaning over time.

Preservation trimming removes only dead, diseased, or crossing branches that threaten tree health, maintaining the natural canopy structure. Over-trimming stresses trees by removing too much photosynthetic capacity. Proper cuts are made at branch collars to encourage compartmentalization, while topping or lion-tailing creates weak regrowth and increases storm damage risk.

Trees with extensive trunk decay, severe root damage near foundations, or large dead sections pose safety hazards that trimming can't resolve. Storm-damaged trees with split trunks or those leaning toward structures often can't be stabilized. Removal becomes necessary when preservation efforts would be costly without restoring structural integrity or when species are poorly suited to the site.

Defined paths prevent soil compaction in high-traffic areas where foot traffic kills grass and creates muddy zones during rain. Proper walkway placement directs movement away from delicate plantings and irrigation heads. Graded walkways channel water toward drainage areas instead of allowing it to pool near foundations or entryways.

Heat retention matters in Central Texas since some materials become too hot for barefoot use in summer sun. Drainage requirements depend on slope and proximity to the home. Maintenance tolerance varies—sealed surfaces resist staining but need reapplication, while natural stone weathers without treatment but may shift on clay soil without proper base preparation.
