Drainage problems on Derby properties frequently trace back to improperly compacted backfill or grading that slopes toward the foundation rather than away from it. Sedgwick County's clay soils make this worse -- clay swells when wet and creates lateral pressure against foundation walls. Sunflower Plumbing grades to direct water away from structures and backfills in properly compacted lifts to prevent long-term settling. Foundation backfill is one of the most commonly rushed steps in construction. The excavated material gets pushed back in quickly, without compaction, and within a few seasons the grade around the foundation has settled and water is running toward the building instead of away from it. Correcting negative grade after the fact is disruptive and expensive -- doing it correctly at backfill is straightforward. For drainage correction on established properties in Derby, we assess where water is pooling or running toward the structure and regrade to redirect it. This sometimes involves bringing in select fill material -- not all native clay is suitable for backfill, particularly when it has been mixed with organic material from topsoil stripping. Lot leveling for properties with uneven terrain or settled areas involves cutting high spots and filling low spots with compacted material. We bring the lot to a consistent grade that drains correctly and provides a stable surface for whatever comes next -- lawn, landscaping, or pavement.
We grade with long-term drainage in mind -- not just enough slope to pass an inspection on day one.
Negative grade around a foundation gets worse every wet season in Derby. Correcting it early is significantly cheaper than addressing foundation damage later.

Settlement happens when backfill is placed too quickly without compaction, or when wet clay is used for backfill and then dries and shrinks. We backfill in properly compacted lifts � each layer compacted before the next goes in � to eliminate long-term settling.
Usually yes. Standing water near a foundation almost always indicates negative grade � the yard slopes toward the structure rather than away. This is a fixable grading issue in most cases. We assess the existing grade and correct it.
Yes, though some disruption is unavoidable when correcting significant grade issues. We work to preserve existing vegetation and hardscaping wherever possible and discuss the scope of disruption with you before we start.
The standard recommendation is a minimum 6-inch drop in the first 10 feet away from the foundation. This ensures surface water moves away from the structure consistently, even after soil settles slightly.
We handle both in the same scope. After any excavation � sewer, water line, septic � we backfill properly and restore the grade. No need to bring in a separate grading contractor after excavation work.
Yes. Lot leveling, low-spot filling, and topsoil addition for final grading are part of our site work scope. We'll discuss the scope and material quantities during the estimate.
