Excavation and Site Work in New Hampshire

Young's Excavating & Paving LLC is an excavation and site work contractor based at 37 Washington Street in Penacook, a village within the city of Concord, NH. The company does site preparation, grading, drainage, foundation excavation, driveway excavation and utility trenching for homeowners, builders and businesses across six New Hampshire counties, with its own excavators, loaders and trucks.

Excavation is where every good project starts. Before there is a driveway, a parking lot, a foundation or a drainage system, there is ground that has to be moved, shaped and compacted correctly.

What excavation and site work does Young's Excavating & Paving LLC do for homeowners?

Young's Excavating & Paving LLC does residential excavation and site work across central and southern New Hampshire: driveway excavation, cut-ins and regrading, land clearing and lot preparation, drainage correction when water is going where it should not, and trenching, backfill and grading for additions and outbuildings.

If a property has a water problem, a grade problem or a project that starts with digging, the company can look at it and give a straight answer about what it takes to fix. Small jobs are welcome, and excavation does not have to be attached to a paving project.

Site Preparation

Clearing, cut and fill to the grade the plan calls for, and a compacted base ready to build on. Water is routed off the site first, because the base and the drainage under a surface decide how long it lasts.

Foundation Excavation

Digging and backfilling for foundations, slabs, additions and outbuildings, cut to the depth and grade the plan calls for. Spoil is handled on site or hauled away and the area is left ready for the next trade.

Asphalt/Concrete Demolition

Breaking out and removing failed asphalt, concrete pads, walkways and old driveway surfaces. Removal can be scheduled with the paving that follows so the site is not left open in between.

Why does drainage decide how long a site lasts?

Drainage decides how long a site lasts because New Hampshire freezes and thaws are what destroy pavement and flood basements. Most excavation problems trace back to water. Proper pitch, working catch basins and correct base drainage protect everything built on top of them. It is the least visible part of the job and the most important one. See examples on our drainage projects and excavation projects pages.

What happens during excavation and site preparation?

A sound excavation and site preparation job in New Hampshire usually runs in the same order, whether the site is a driveway, a house lot or a commercial parking lot.

Step 1Utilities are marked first.In New Hampshire, Dig Safe has to be notified before any digging so buried gas, electric and water lines are marked.
Step 2The site is cleared and the topsoil is stripped.Topsoil and roots hold water and compress over time, so they come out from under anything that will be built or paved.
Step 3The ground is cut and filled to grade.The grade is set so water runs off and away, with a fall of roughly a quarter inch per foot under paved surfaces.
Step 4Soft spots are found and replaced.Wet clay, silt or loose fill in the subgrade is dug out and replaced with material that drains.
Step 5Drainage goes in before the surface.Catch basins, culverts, swales and pipe are set while the ground is open, not after it is paved.
Step 6The gravel base is placed and compacted in layers.Crushed gravel is compacted a few inches at a time, usually no more than about 6 to 8 inches per layer, so the bottom is as firm as the top.
Step 7The site is paved or handed to the next trade.A prepared base is ready for asphalt, a slab, a foundation or a building.

Skipping any of these steps rarely shows on day one. It shows the first spring, when frost has lifted a soft spot or water has found the low point. More on how the two halves connect is in excavation and paving with one New Hampshire contractor.

Why the base decides how long the surface lasts

Almost every failed driveway in New Hampshire failed underneath before it failed on top. Frost drives several feet into the ground here through the winter, and any water trapped in the base expands as it freezes and lifts whatever is sitting on it. When it thaws, the ground drops back unevenly and the surface above it cracks along the line of the movement. That is why a driveway can look fine in November and have a crack down the middle by April.

Good site work is mostly about not letting water sit. That means cutting to a grade that sheds water rather than holding it, a base of clean crushed stone that drains instead of soil that holds moisture, and compaction in layers rather than all at once, because a thick layer of gravel compacts on top and stays loose underneath. Asphalt over loose base is asphalt with nothing under it.

Slope is the part nobody thinks about until it is wrong. A paved surface needs a consistent fall of roughly a quarter of an inch per foot to move water off it reliably. Less than that and water sits in the low spots, freezes, and works into the surface. On a site with nowhere for the water to go, that means catch basins and a run to somewhere it can discharge, and that is a decision made before anything is paved, not after.
