Block Foundations Our Masons Build

As a block foundation contractor, we start every job with a poured footing and a height set for the lot.

Foundations for Additions, Sunrooms, and Porches

We build every foundation for home addition work to your existing floor height. A sunroom foundation ties into the house per the plans, and so does each porch foundation.

Raised Foundations for Low and Flood Prone Lots

A raised foundation uses taller crawl space walls to lift the floor to the required height. Every flood zone foundation gets flood vents where required.

A masonry foundation with a crawl space is our usual pick on low Greenville NC lots and for additions to crawl space homes. Slab options are on our concrete slabs page.

Vents, Access Openings, and Termite Gaps We Build Into Every Crawl Space

Every crawl space we build includes:

  • Vented crawl spaces

Foundation vents totaling at least 1 square foot of net vent area per 150 square feet of crawl space, or 1 per 1,500 with a ground vapor retarder and cross ventilation.

  • Corner placement

Crawl space vents set with one within 3 feet of each corner of the building.

  • Access

An opening of at least 18 by 24 inches.

  • Clearance

Code clearance under joists and girders.

  • Closed crawl space ready

The masonry top stays 3 inches above any liner, the gap termite inspectors need, and the crawl floor slopes to a low spot with a drain or sump.

We build to the 2024 North Carolina Residential Code and confirm whether your plan is vented or closed. See the NC Office of State Fire Marshal residential code.

Footing, Block, Steel, and Anchors: How
We Build a Foundation That Stays Level

How High Your Foundation Should Sit on a Low or Flood Prone Greenville NC Lot

We set foundation height from lot grade, drainage, and flood elevation before the first block. The City of Greenville NC enforces a Flood Damage Prevention Ordinance for mapped flood zones, with about 10,004 acres of floodplain in its jurisdiction. There the floor must sit at the required elevation for your lot, so we build walls tall enough and add flood vents where required. See the City of Greenville NC flood information.

On flat, slow draining Pitt County NC clay near the Tar River, we raise and grade block foundations so water does not sit against the wall.

Addition Foundations That Match Your Existing Floor and Brick

We match the existing floor height, tie the new footing and block to the existing foundation per the plans, face the walls with brick to match, and set piers under every new girder so the addition does not sag.

Cracked Block Walls or Crumbling Brick Piers Under an Older Home

We build new block foundations, piers, and walls. When a house needs underpinning, steel piering, jacks, or crawl space encapsulation, we say so plainly and recommend a foundation repair specialist, because we do not sell those systems.
