Slab foundation building in South Burlington VT - a floor planned to keep radon out
Planning a new home on a slab? We plan the layers underneath first, so the floor is built to stay dry and radon has a way out.
What slab foundation building does for your home
Slab foundation building in South Burlington, VT, means pouring a concrete floor directly on the ground, called slab-on-grade, to carry a home or another building. At South Burlington Concrete, we pour slabs for new homes and additions. We also handle foundation installation with walls and footings, and the larger pours of concrete parking lot building.
I plan the layers under the slab before anything is poured, because radon and moisture protection are much harder to add later. If the budget gets tight, I'd keep the money in the subgrade, the packed base the slab sits on, since it's hidden on day one and hard to fix afterward. The price usually turns on the slab's size and what goes under it, the schedule on the weather and what the city needs, and my written estimate lists the work for your lot.
Here in South Burlington, the city requires the main home on a lot to meet the state's stretch energy code. Without a recorded certificate showing that in the city's land records, the building counts as built without a zoning permit, so we settle the insulation under and around the slab with your building plans before the pour, not after.
Slab foundations planned in order
Since 2017, I've planned slabs so the work happens in the right order, with the base, the radon and moisture layers and any cold-weather protection settled before the truck arrives.

Slab foundation questions we hear
Is a frost-protected shallow foundation right for my lot in South Burlington?
It's usually a strong choice when your home sits on a slab and the lot is fairly flat, since the design guide calls it best suited to low and moderate slopes. Insulation placed around it keeps the soil warmer so the foundation can sit shallower, and it can go in with one pour and fewer inspections. I'll check your slope when I walk the lot.
How is a new slab built to keep radon out in Vermont?
We lay a bed under the slab that gas can move through, often clean gravel, with plastic sheeting on top, as the Vermont Department of Health describes, and that sheeting blocks moisture as well. The same guidance describes a vent pipe carrying radon outside above the roof. Radon is common in Vermont homes, so please ask us to plan a junction box in case a fan is needed later.
Can you pour a slab foundation in cold weather?
Yes, a slab can be poured in the cold with added steps to keep the concrete at the temperatures it needs while it cures and gains strength. The cold-weather guide says insulating covers may be enough in milder weather, while low temperatures or high winds can call for enclosures and heaters. If conditions are poor, I'd rather move the pour date.
Who reviews construction work in South Burlington, and do I need a permit?
In South Burlington, the Development Review Board reviews construction work, and some types of work only need an administrative permit that the Zoning Administrator can approve. Before we set a date, we check what your slab needs and help you prepare and file it. If you'd like to ask yourself, the city can tell you which permit fits at 802-846-4106.
Does a slab contractor have to be registered in Vermont?
Yes, when the job is worth more than $10,000.00 in labor and materials. State law requires anyone contracting with a homeowner for residential construction to register with the Office of Professional Regulation first, so it's fair to ask a contractor about registration before you sign.
How much does a slab foundation cost in South Burlington?
I price each slab in a written estimate after walking your lot, because the figure comes from your site and your plans. The slab's size and thickness, the digging and base work, and the insulation, radon and moisture layers underneath usually move it most, and a cold-weather pour adds protection to the job.
