Does a portable shed need a concrete foundation?

No — portable sheds are designed to sit on gravel pads, treated wood runners, or concrete blocks. A full concrete slab is optional and typically not required. It does improve drainage and longevity in wet climates.

What is the most popular foundation for sheds in North Texas?

A gravel pad is by far the most common. 4-6 inches of crushed gravel, level and compacted, gives excellent drainage and a stable base. It costs $200-$600 for most shed sizes depending on whether you DIY or hire out.

Can I put a shed directly on the ground?

We do not recommend it. Ground contact accelerates wood rot and creates moisture problems. At minimum, use pressure-treated 4x6 runners elevated slightly above grade.

Who is responsible for the foundation — me or the shed company?

You are responsible for preparing the site before delivery. We handle the shed delivery and setup on whatever foundation you have ready. We can advise you on what to prepare and connect you with local gravel suppliers.

How level does the foundation need to be?

Within 1-2 inches across the full footprint. Our crew can handle minor adjustments on delivery day, but significantly uneven ground needs to be addressed beforehand.

Shed Foundation Options for North Texas

What foundation do you actually need for a portable shed? Gravel, concrete, blocks, or runners — here is what works in North Texas clay and sand soils.

Quick Answer

For most North Texas buyers, a 4-6 inch crushed gravel pad is the best foundation — it drains well, is easy to DIY for $200-$600, and handles the clay soil that causes shifting. Concrete slabs are worth it for workshops and heated/cooled spaces. Direct ground contact is not recommended.

North Texas Soil Note: Clay Matters

Much of Denton County sits on expansive clay soil that swells when wet and shrinks when dry. This causes concrete blocks to shift and direct-ground setups to tilt over time. A properly compacted gravel pad with landscape fabric underneath is the best long-term option for most North Texas properties. Ask us — we've seen what works and what doesn't across hundreds of deliveries.

How to Prepare a Gravel Pad (DIY)

1
Mark the area: Add 1 foot on each side of your shed footprint (e.g., 12x14 pad for a 10x12 shed)
2
Excavate 4-6 inches of soil and remove any grass or roots
3
Add 2 inches of compacted base material (road base or caliche)
4
Lay landscape fabric to suppress weeds
5
Add 4 inches of crushed gravel (3/4 inch crushed limestone is best in North Texas)
6
Rake level — must be within 1-2 inches across the full footprint
