"Integrity, quality, safety, and our employees form the foundation of the success at McMahon Contracting." - Shawn & Jayce McMahon

1 Excavation & Stabilization:
Critical to the excavation & stabilization phase of construction is the value and safety placed on identifying existing utilities that may be in conflict.
The excavation & stabilization crews at McMahon Contracting are responsible for all initial site excavation and subgrade stabilization.

2 Utilities:
Water From relocation and installation of 3/4 inch residential and commercial services to 36 inch reinforced concrete cylinder pipe.
Sewer From relocation and installation of 4 inch residential and commercial services to 20 feet-deep 12 inch trunk lines. Additionally, we have the ability to construct entry manholes and lift stations.
Storm Drain From 15 inch reinforced concrete pipe to multiple-span reinforced concrete box culvert. Additionally, we have the ability to construct gabion and concrete-lined drainage channels.

3 Structures:
Our structure crews are capable of constructing inlets, manholes, headwalls, retaining walls, and multiple-span cast-in-place box culverts.

4 Paving:
Our paving crews focus on all facets of concrete paving; sidewalks, exposed aggregate & specialty surfaces, driveways, parking lots, utility line patching, and slipform paving. We are proud to be backed by the industry leader in concrete paving, Gomaco Corporation.

5 Restoration:
Paramount to the success of a project is owner satisfaction. It is the restoration phase of construction that allows McMahon Contracting to provide the ultimate satisfaction to the owner.
As a project nears completion, our restoration crews are diligently working on final punchlists to return a quality product to the owner.
