Yes. Gravely Hydroseeding & Excavating installs conventional gravity septic systems, pump systems, and mound systems for residential and commercial properties in Henderson County and surrounding Western North Carolina counties. We manage the excavation and installation from start to finish and coordinate with the local health department for permitting.

Common signs of a failing septic system include slow-draining sinks, toilets, or showers; sewage odors inside or outside the home; wet, soggy, or unusually lush green patches of grass over the drain field; gurgling sounds from drains or toilets; and sewage backing up into the home. If you notice any of these signs, contact a septic professional promptly — delays can result in more extensive and costly repairs.

A septic drain field (also called a leach field) is a network of perforated pipes buried in gravel trenches that allow treated wastewater to slowly absorb into the surrounding soil. Drain fields fail most commonly due to biomat buildup — a layer of organic material that clogs the soil and prevents absorption — as well as root intrusion from nearby trees, soil compaction from vehicles driving over the field, or an undersized system for the property's usage. Once a drain field fails, excavation and replacement of the affected lines is typically required.

Yes. We excavate failed or damaged drain fields, replace collapsed or clogged leach lines, and restore proper function to conventional gravity and pump septic systems. We also expand or reroute lines when the original layout is undersized or improperly placed for the site conditions.

Yes. For new construction in Henderson County, the process begins with a site evaluation and percolation (perc) test performed by a licensed soil scientist. Once approved by the Henderson County Health Department and a permit is issued, we excavate and install the system to meet NC state and county specifications. We coordinate with your soil scientist and building team to keep the project on schedule.

A percolation test (perc test) measures how quickly water drains through the soil on your property. In North Carolina, a perc test and site evaluation performed by a licensed soil scientist is required before a septic permit can be issued for a new system. The test results determine what type of system your lot can support. Gravely Hydroseeding & Excavating can grade and prepare your test site to ensure the evaluation process goes smoothly.

Yes. When a property connects to a public sewer line, the existing septic tank must be properly decommissioned — typically pumped, crushed or filled, and buried — in accordance with NC regulations. We handle the excavation and decommissioning process and coordinate with your local health department to ensure all requirements are met.
