Concrete Caulking & Sealing in Sioux Falls, SD
Lifting a slab without sealing the joints is half a job: the same water that washed the soil out will wash it out again. Concrete Raising Sioux Falls seals joints and cracks as part of every lift — and offers caulking and sealing as a standalone service for slabs that are still level and worth protecting.
In Sioux Falls, joint sealing is not cosmetic. Every winter, water in an open joint freezes, expands, and pries the joint wider; every spring, meltwater runs down into the void it opened. Sealed joints break that cycle. It is the cheapest maintenance a concrete slab ever gets.
What sealing does
A flexible sealant in the joints and cracks keeps surface water out of the base — and water is the cause of almost every sunken slab in this market. Sealing after a lift protects the fill underneath; sealing a level slab before it sinks can delay or prevent the lift entirely. It also stops weeds growing through joints, keeps de-icing salts out of the slab edge, and makes the whole surface look finished.
We seal with flexible, weather-rated joint sealant, not a rigid filler that cracks with the first freeze. Cracks are routed and filled; joints are cleaned, backer rod is set where needed, and the sealant is tooled flush.
When to seal
After any lift, always — it is part of the job. On a level slab, the best time is late spring or early fall, when the joints are dry and the sealant can cure before the next freeze. If your joints are open, crumbling, or full of weeds, they are already past due. Sealing pairs naturally with a lift estimate: if we are already on site lifting, sealing the rest of the slab is a small addition that protects the whole surface.
Questions
How much does concrete sealing cost in Sioux Falls?
Joint sealing is priced by the linear foot after a look at the slab — it is a small fraction of a lifting job, and it is included in the price of every lift we do. Call or send photos for a free estimate.
Does sealing really stop a slab from sinking?
It stops the most common cause: water washing soil out from under the slab. Sealing cannot fix bad compaction or a drainage failure on its own — but combined with a lift and working drainage, it is what keeps the slab level.
Can you seal my driveway if it has not sunk yet?
Yes — and that is the best time. Sealing a level slab is preventive maintenance, and it costs far less than lifting the same slab later.
