Waianae Excavation & Demolition | Septic Repair & Trenching | Hawaiian Excavations

A failing septic system often requires a full replacement. We start with a plumbing inspection to locate the problem, then perform precise trench digging for the new leach field and tank area. Our excavation and demolition services safely clear the site and prepare it for your new, compliant system, helping you avoid further property damage common in our local soil conditions.

Absolutely. Severe septic failures can compromise foundations or outbuildings. We offer partial or total structure demolition to safely remove damaged sections, followed by the excavation needed for the new system installation. We handle everything from interior demo of affected areas to full site clearing, ensuring a clean slate for your rebuild here in Waianae.

We provide a complete solution. Beyond just trench digging to access and replace damaged underground lines, we can perform exterior surface and wall demolition if the clog caused a backup that damaged slabs or exterior walls. Our full-service approach addresses both the immediate excavation need and any related structural issues to fully restore your property.
