Shed Pad Concrete Lifting Specialists
Olympic Concrete Lifting provides professional shed pad concrete lifting and stabilization for sunken, uneven, and unsupported concrete slabs throughout the Kansas City area.
When the soil beneath a shed pad settles, washes away, or develops voids, portions of the slab can begin to sink or tilt. Polyjacking can often restore support and carefully raise structurally sound concrete without tearing out the pad and starting over.
Keep Your Shed on a Stable Surface
A concrete pad provides a solid base for sheds and other small outdoor structures, but the slab is only as stable as the material beneath it. Soil settlement, erosion, poor compaction, and drainage can all cause support to disappear over time.
As the slab moves, the shed above it may begin to sit unevenly or develop noticeable changes around doors, corners, and surrounding surfaces.
Concrete leveling & polyjacking works beneath the pad by injecting expanding polyurethane foam into areas where support has been lost. The foam fills empty space, stabilizes the slab, and can carefully raise settled sections when conditions allow.
Signs Your Shed Pad May Be Settling
Why Shed Pad Settlement Matters
A shed pad does more than create a clean place for a structure to sit. It helps provide a stable, consistent base beneath the entire shed.
When part of the slab settles, the load above it may no longer be supported as evenly as intended. Even if the concrete has not severely cracked, continued movement can make the slab and structure noticeably uneven.
Addressing lost support beneath the pad can help preserve the existing concrete while correcting settlement before the condition becomes more pronounced.
Benefits of Shed Pad Concrete Lifting
When the existing concrete remains structurally sound, lifting can provide a practical alternative to demolishing the pad and building a new one. Polyurethane foam allows the problem beneath the slab to be addressed with minimal disruption around the shed.
Restore Slab Support
Polyurethane foam fills voids beneath the concrete and helps replace support lost through soil settlement or erosion.
Correct Uneven Areas
Settled portions of the pad can often be carefully raised toward a more appropriate elevation.
Preserve Existing Concrete
A good concrete slab does not necessarily need replacement just because the material underneath it has moved.
Minimize Disruption
Polyjacking requires small injection points and avoids much of the demolition and cleanup involved with replacing a pad.
Lightweight Material
Polyurethane foam provides support without adding a large amount of heavy material beneath already settled soil.
Fast Cure Time
The foam cures quickly, allowing the stabilization process to be completed without the extended curing period of newly poured concrete.
Leveling vs. Stabilizing a Shed Pad
The Pad May Need Support, Lifting, or Both
Shed Pad Leveling
If one portion of the slab has already sunk, polyurethane foam may be used to fill the space beneath it and carefully raise the concrete.
Shed Pad Stabilization
If empty spaces have developed underneath but the slab is still close to the correct position, void filling may be used primarily to restore support.
The right approach depends on the amount of movement, the condition of the slab, drainage around the pad, and the structure sitting above it.
What Causes Shed Pads to Sink?
Shed pads can settle for several reasons. Soil may not have been adequately compacted before the slab was poured, or the ground can naturally compress over time. Water flowing around the shed may also erode material from beneath the concrete and create hidden voids.
The placement of a shed can make drainage especially important. Roof runoff, slopes, and bare soil around the pad may repeatedly direct water toward the same area. When runoff from the structure is contributing to erosion, Downspout Extensions can help carry water farther from the shed pad and surrounding soil.
Where erosion has created empty space without significant slab movement, void filling may help restore support before additional settlement develops.
Our Shed Pad Lifting Process
Evaluate the Pad
We inspect the concrete, amount of settlement, visible voids, drainage conditions, and the structure sitting on the slab.
Plan the Correction
Injection locations and the amount of lifting or stabilization needed are determined based on the pad and surrounding conditions.
Inject Polyurethane Foam
Small holes allow expanding polyurethane foam to reach empty spaces beneath the slab.
Lift & Stabilize
The foam fills voids, restores support, and carefully raises qualifying areas of the concrete where elevation correction is needed.
Can a Shed Stay on the Pad During Lifting?
In some situations, a shed may be able to remain in place while the pad is evaluated and repaired. However, the size and weight of the structure, condition of the slab, amount of settlement, and any attached utilities or other connections all need to be considered first.
Olympic Concrete Lifting evaluates the entire setup before determining whether lifting can be performed safely and what preparation may be needed.
When Replacement May Be the Better Option
Not every shed pad is a good candidate for lifting.
If the slab is severely fractured, crumbling, improperly sized, or otherwise structurally unsuitable, replacement may make more sense. A pad with relatively good concrete but poor support underneath is much more likely to benefit from lifting or stabilization.
Olympic Concrete Lifting can evaluate the condition of the slab and determine whether polyjacking, concrete repair, void filling, or replacement is the most practical approach.
Related Concrete Around Your Property
Shed pads often sit near other residential concrete that can experience similar soil and drainage conditions.
If settlement is affecting the surrounding property, Olympic Concrete Lifting can also evaluate Driveway Lifting, Residential Walkway Lifting, Patio Lifting, Garage Floor Leveling, and other concrete surfaces. Addressing multiple problem areas at the same time can help determine whether drainage or soil movement is affecting more than one slab.
Shed Pad Concrete Lifting FAQs
What causes a concrete shed pad to sink?
Settlement can result from soil compression, poor compaction, erosion, drainage issues, moisture changes, or voids that develop beneath the slab.
Can a shed pad be lifted without replacing it?
Often, yes. If the slab remains structurally sound, concrete leveling & polyjacking may be able to restore support and correct settlement without full replacement.
Can you fill a void without raising the pad?
Yes. When the slab is still at an acceptable elevation but has lost support underneath, void filling may be used primarily to stabilize it.
Can the shed stay on the concrete during lifting?
Possibly. The structure, slab condition, amount of settlement, weight, access, and any attached utilities or connections need to be evaluated first.
Can a cracked shed pad still be lifted?
Minor cracking does not automatically rule out lifting, but heavily damaged concrete may also require concrete repair or replacement.
Can lifting fix a tilted shed?
If the tilt is being caused by settlement of the concrete pad, correcting the slab may improve the condition. Other structural issues with the shed itself would need to be addressed separately.
Does drainage affect shed pad settlement?
Yes. Water repeatedly moving around or beneath the pad can erode supporting soil and contribute to void formation and settlement.
How do I know whether the pad needs lifting or replacement?
The condition of the concrete, amount of settlement, support beneath the slab, and structure above it all matter. A free assessment can help determine the appropriate solution.
