Learn How to Build Brick Steps Yourself

Understanding Brick Step Basics and Materials

Building brick steps requires understanding the fundamental materials and components that make up a durable outdoor staircase. Brick steps are among the most popular outdoor construction projects because they provide a classic appearance, long-lasting durability, and relatively straightforward construction methods. When properly installed, brick steps can last 50 years or more with minimal maintenance.

The primary materials you'll need include bricks, mortar, concrete, and gravel. Standard brick dimensions are 3 5/8 inches wide by 2 1/4 inches tall by 7 5/8 inches long, though sizes vary by manufacturer. You'll also need Portland cement, sand, and water to create mortar, which acts as the adhesive binding bricks together. A typical step requires approximately 60 to 100 bricks depending on the width and height you're building.

Beyond bricks and mortar, you'll need a solid foundation. Most brick steps rest on a concrete base that's typically 4 to 6 inches thick. This concrete foundation prevents settling and shifting over time, which could crack your bricks or create uneven steps that pose safety hazards. The concrete should extend below the frost line in your region to prevent frost heave—the upward movement of soil caused by freezing and thawing cycles.

Understanding regional considerations matters significantly. In areas with significant freeze-thaw cycles, bricks must be rated for freeze-thaw resistance. The Brick Industry Association rates bricks as SW (severe weathering), MW (moderate weathering), or NW (negligible weathering). For outdoor steps in cold climates, SW-rated bricks are essential for longevity.

Practical Takeaway: Gather and inspect all materials before beginning. Purchase approximately 10 to 15 percent extra bricks to account for breakage and cutting. Verify that your bricks have appropriate weathering ratings for your climate zone.

Measuring, Planning, and Design Considerations

Proper measurements determine whether your steps will be safe and comfortable to use. Building codes and ergonomic standards provide specific guidelines for step dimensions. The rise (vertical height) of each step should be between 4 and 8 inches, with 6 to 7 inches being the most comfortable for most people. The tread (horizontal depth) should be at least 10 to 11 inches deep, though 12 inches is preferable for stability and comfort.

To calculate how many steps you need, measure the total vertical distance from your upper surface to your lower surface. If you're building from a doorway to the ground and that distance is 28 inches, you would divide 28 by 7 inches (a standard rise height) to get four steps. Always round up if you get a decimal number, then recalculate the exact rise by dividing the total height by your new step count. This ensures all steps are identical in height, which is crucial for safety.

Consider the step width carefully. Steps narrower than 3 feet feel cramped, while steps 4 to 5 feet wide feel more generous and safer. For steep slopes or locations where space is limited, you might build narrower steps, but wider is generally better. A standard width accommodates two people walking side by side and makes moving larger items like furniture easier.

Plan your design on paper before digging. Sketch the side view showing each step with proper rise and tread measurements. Mark where the concrete foundation will sit. Note the slope of the ground and any obstacles like trees, utilities, or drainage areas. Many builders create a wooden template—essentially a stair-step shaped board—that helps them visualize the final product and verify measurements.

Account for water drainage. Steps should slope slightly away from any adjacent structures. A slope of 1/8 inch per foot prevents water from pooling on the step surface, which can cause ice formation in winter and accelerate deterioration.

Practical Takeaway: Create a detailed side-view sketch showing exact measurements for rise, tread, and overall dimensions. Double-check all calculations before marking the ground. Verify that the total rise divides evenly by your chosen step height to ensure uniform steps throughout.

Preparing the Foundation and Subgrade

A strong foundation prevents step failure and extends the life of your brick work significantly. The foundation process begins with site preparation. Mark the area where your steps will be built using string lines and stakes. Excavate the area to a depth that accommodates your concrete base plus the height of your bricks. Most installations require digging 6 to 8 inches deep.

Remove all topsoil and organic material from the excavation area. Topsoil contains decomposing organic matter that shifts as it breaks down, creating an unstable base. Dig down to undisturbed soil or, in some cases, clay, which provides a more stable foundation. The excavated area should be rectangular and slightly wider than your planned steps to accommodate the concrete pad.

Compact the soil at the bottom of your excavation using a hand tamper or mechanical compactor. Proper compaction prevents settling. For areas with poor drainage or heavy clay soil, you may want to add a 2-inch layer of gravel, which improves drainage and provides additional stability. Compact this gravel layer as well.

Build a wooden form or frame to contain your concrete. Use 2x4 or 2x6 boards depending on your step height. The form should match your step outline exactly. Secure the boards with stakes and bracing to prevent concrete from pushing them outward during pouring. The concrete should be at least 4 inches thick and extend at least 12 inches beyond your brick steps in all directions to provide lateral support.

If you're building on a significant slope, you may need a stepped foundation. Rather than one flat concrete pad, the concrete steps up in stages corresponding to your brick step heights. This technique requires more planning but provides superior support on steep terrain.

Practical Takeaway: Thoroughly compact the subgrade before pouring concrete. Build sturdy wooden forms and brace them securely. Ensure the concrete pad extends well beyond your planned brick steps to provide adequate support and prevent lateral shifting.

Pouring and Setting Your Concrete Base

The concrete base provides the critical foundation for your brick steps, so proper installation is essential. Mix concrete according to manufacturer instructions, typically combining one part Portland cement, two to three parts sand, and three to four parts gravel or stone. You can purchase pre-mixed concrete in bags (requiring hand mixing for small projects) or have ready-mix concrete delivered in a truck for larger installations.

For a typical set of four to six steps, you'll need approximately two to three cubic yards of concrete. Calculate your volume by multiplying length times width times depth (in feet) and dividing by 27 to convert to cubic yards. Having enough concrete delivered to complete the entire job in one pour is important because concrete is stronger when poured as one unit rather than in multiple stages.

Pour concrete into your forms and work it thoroughly to remove air bubbles. Use a shovel or vibrating tool to settle the concrete and eliminate voids. Strike off excess concrete using a straight board dragged across your forms to create a level surface. The concrete surface should be slightly rough rather than perfectly smooth, as this helps mortar bond better to the bricks.

Allow concrete to cure for at least five to seven days before applying weight. During this curing period, keep the concrete moist by misting with water or covering with plastic. Proper curing develops concrete strength. Curing in cool, damp conditions produces stronger concrete than rapid drying in hot weather. In very hot climates, you may need to mist the concrete multiple times daily to slow evaporation.

Once cured, you can remove the wooden forms. Check the concrete surface for any high spots, cracks, or uneven areas. Use a cold chisel and hammer to remove high spots if necessary. Any significant cracks (wider than 1/4 inch) may indicate a problem with the concrete mix or curing and should be sealed before adding bricks.

Practical Takeaway: Order enough concrete to pour all at once rather than in multiple batches. Thoroughly consolidate the concrete to remove air pockets. Allow proper curing time before proceeding with brick installation. Mist the concrete during curing in hot weather to ensure strength development.
