Insulated Concrete Formed Walls

Seneca Foundations provides Western Pennsylvania builders and property owners with Cast in PlaceFormed Wall (CIP) and Insulating Concrete Formed Walls (ICF) systems.

Excavation and Grading Projects

Do you need site preparation and a foundation or just regrading and better drainage in the backyard?

Excavation projects done correctly.

Excavation on any construction project is a very critical part of the project. It is important that the job is done safely, thoroughly and correctly in order to have a level site that drains properly and that all conditions and precautions are understood prior to digging. The Graf excavation experts have the knowledge and equipment to perform a wide variety of excavation services including demolition, leveling and grading and trenching.

PA One Call

All excavators must contact PA One Call at least 3 business days prior to excavation, as required by law.

Pennsylvania One Call System is a non-profit Pennsylvania corporation created to protect the underground facilities before anyone begins to disturb the earth. PA One Call receives requests from excavators, contractors, plumbers, builders, designers, and the general public to find out where underground lines are located. Pennsylvania One Call notifies member underground facility owners of the intent to excavate. The member underground facility owner then marks where their lines are located.
