Foundation block wall installation in Fargo ND - basement walls planned for clay soil
Building a new basement or addition in Fargo? We lay block walls course by course and plan the water protection with you first.

What goes into building a block foundation wall in Fargo?
Foundation block wall installation in Fargo means laying concrete block one course at a time on a footing to build basement walls that hold back the soil around your house, with water protection matched to your lot.
Most people who call about this are building a new house or an addition, or replacing a basement wall that's past saving. If yours can still be saved, foundation repair usually costs less, and I'll tell you so. The price moves mostly with the wall's area in square feet, whether it's plain or reinforced, and whether it needs dampproofing or full waterproofing. The schedule turns on how soon the city confirms your lot's flood status and any permit, because in Fargo that can decide whether block is an option at all. Your estimate explains what we'd build and why, so you know what you're paying for before anything starts.

Two kinds of block foundation wall
The right wall depends on how hard the soil pushes against it and how wet that soil stays, so we choose it after looking at your lot and backfill.

Why homeowners trust Masoncraft with block foundation walls
I ask the city early about your lot's flood status and whether block suits it, because there's no sense drawing up a block wall the city won't accept. Then we talk through whether your basement needs dampproofing or full waterproofing, and I explain why I'd pick one for your soil before asking you to agree.
On some Fargo lots, old low spots and drainage paths were filled during rushed building with poor or badly placed backfill, so we look at what's in the ground before planning the wall. Once the walls are up and backfilled, the yard usually needs work too, and we can lay a new walkway or build outdoor kitchen masonry when the ground is ready.
Questions about block foundations
How much does a block foundation wall cost in Fargo?
Across the US, installing a concrete block wall usually costs about $15.50 to $19.50 per square foot, and that's a national market figure, not our price. Your price moves with the wall's area, whether it's reinforced, which water protection it needs and what the dig and backfill involve. I measure on site and write it into your estimate, so you can see what we'd do and why.
Can I build a block foundation on a lot near a flood area in Fargo?
Your lot's flood status decides it, and the City Engineer is the one who determines which areas count. If part of your lot is in a mapped flood area but the house sits outside it, the city requires a standard concrete foundation without saying whether block qualifies, so we ask the city before planning a block wall. A house inside a flood area must meet all floodproofing codes plus the city's elevation and fill rules, and a lot entirely outside has no floodproof rules, though the city recommends a concrete foundation or floodproof construction.
Do I need a permit for a block foundation wall in Fargo?
If the house will sit in one of Fargo's mapped flood areas, the city needs a floodproofing certificate signed by an engineer before it will issue the permit. For other lots, ask Fargo's Inspections Department, which enforces the building code and takes calls at 701.241.1561. We check with the city before we start, handle the paperwork when a permit is needed and tell you what we found.
What is the best way to keep water out of a new block basement in Fargo?
If your backfill is heavy clay, as it usually is in Fargo, plan on full waterproofing, because the city sits on the old lakebed of glacial Lake Agassiz, and that soft clay can hold water against the wall. Masonry trade guidance says codes typically call for waterproofing where water in the soil may press against the wall, and dampproofing, a lighter coating, where it won't. Dampproofing fits lots that drain well, such as ones with gravelly backfill and a drain line below grade.
Does a contractor need a license to build a foundation in North Dakota?
Yes, once a job's cost, value or price is over $4,000, the person doing it must be licensed as a contractor in North Dakota. You can search the state's contractor list to see whether a license is in good standing before you sign, and you're welcome to look us up there too.
How do I compare bids for a block foundation wall?
Compare what each bid says about water protection and wall type, not just the total. Ask whether it includes dampproofing or waterproofing and whether the wall is plain or reinforced, since those choices matter most on clay. It's also fair to ask how the crew preps the footing, because mud, dirt or ice left on top weakens the mortar's bond with the first course.
