Complete Site Preparation

From initial clearing and access through utilities, foundation excavation, grading, and final site preparation, TH Excavation can manage the earthwork required to take a project from raw ground to a build-ready site.

Planning

 We coordinate excavation, site access, material movement, utilities, grading, and related sitework to help keep your project organized and moving efficiently. 

Site access

 Site access, construction entrances, temporary roads, and access improvements for residential and commercial projects. 

Clearing

 Land clearing, brush removal, tree and stump removal, and site preparation for new construction, access, and property improvements. 

Foundations

 Foundation excavation and preparation for slab-on-grade construction, footings and stem walls, basements, garages, additions, and new homes. 

Utilities

 Trenching and sitework for water, sewer, storm, power, communications, gas, and other underground utility systems.
