Solid Foundations for Sheds, Garages & Outdoor Structures
A level, properly drained foundation is the difference between a structure that lasts decades and one that shifts, cracks, and sinks. We build both gravel pads and poured concrete foundations that stand the test of time.
That new shed, detached garage, hot tub, or generator needs a solid base — and in Anne Arundel County, where clay soils shift and water tables run high, cutting corners on the foundation is a recipe for problems. A structure placed on bare ground or a poorly prepared pad will settle unevenly, trap moisture underneath, and start causing headaches within a year or two.
Backyard Bobby's builds gravel pads and poured concrete foundations engineered for the specific conditions on your property. We evaluate your soil, assess drainage, and build a base that distributes weight evenly, sheds water away from your structure, and stays level through Maryland's freeze-thaw cycles. Whether you need a simple 10x12 gravel pad for a prefab shed or a full concrete slab for a two-car garage, we handle the complete process.
We've installed hundreds of foundation pads across Annapolis, Pasadena, Crofton, Severna Park, and the surrounding area. Every one of them started with proper site evaluation and ended with a surface you could trust to support your investment for the long haul.
Backyard Bobby's has installed hundreds of gravel pads and concrete foundations across Annapolis, Pasadena, Crofton, Severna Park, and surrounding communities — each one laser-leveled and built with geotextile fabric and compacted crushed stone engineered for local soil conditions. Licensed MHIC #05-163777. Gravel pads typically install in 1–2 days starting around $1,500; concrete slabs take 2–3 days plus cure time starting around $3,500.

Why Choose Us for Gravel Pads & Concrete Foundations
Gravel & Concrete Expertise
We build both types of foundations and can recommend which is right for your project. Gravel pads are ideal for sheds and lighter structures; concrete is better for garages, ADUs, and heavy equipment. We'll explain the trade-offs clearly.
Proper Drainage Built In
Every pad we build includes a drainage plan. Gravel pads use perimeter grading and compacted stone that lets water pass through. Concrete slabs get slope built into the pour and drainage channels where needed. No standing water, no moisture damage.
Engineered for Local Soil
Anne Arundel County soil varies wildly — heavy clay in Crofton, sandy loam near the Bay, and everything in between. We adjust base depth, material selection, and compaction technique to match what's actually under your yard.
Level & Square Every Time
An out-of-level pad means doors that won't close, walls that don't align, and floors that puddle. We use laser levels and check for square at every stage to guarantee your structure sits perfectly flat.
Sized for Any Structure
From a compact 8x10 hot tub pad to a 24x30 garage foundation, we custom-build to your exact dimensions. We also account for overhangs, door swings, and access paths so the finished pad works for the way you'll actually use it.
Seamless Project Coordination
If your shed, garage, or ADU is being delivered or built after the pad, we coordinate timing so the foundation is cured and ready. Since we also handle excavation and construction, there's no finger-pointing between contractors.
Our Gravel Pads & Concrete Foundations Process
Here's exactly how your gravel pads & concrete foundations project works from start to finish.
Site Evaluation & Measurements
We visit your property, confirm exact pad dimensions based on your structure specs, evaluate soil type and drainage patterns, and identify the best placement. We account for setback requirements, access for delivery trucks, and proximity to utilities.
Ground Preparation & Grading
We excavate the area to the correct depth — typically 6 to 8 inches for gravel pads, deeper for concrete — strip away topsoil and organic material, and grade the subsoil to create proper drainage slope. This step prevents future settling and water problems.
Base Material & Compaction
For gravel pads, we lay geotextile fabric to prevent weed growth and soil mixing, then build up layers of crushed stone — compacting each lift with a plate compactor for maximum stability. For concrete, we set forms, lay compacted gravel sub-base, add rebar or wire mesh reinforcement, and pour to the specified thickness.
Final Surface & Drainage Verification
We verify the finished surface is dead level (or properly sloped for drainage), check all edges and corners for square, and confirm the pad meets the specs for your structure. For concrete, we handle proper finishing and curing. We leave the site clean and ready for your structure delivery or next build phase.

“We needed a gravel pad for our new shed and the team had it done in two days. The drainage is perfect and the price was very fair. Highly recommend.”
