- Outdoor kitchen counters: Serving as durable, weather-resistant surfaces for food preparation and dining in outdoor living spaces.
- Seating: Providing comfortable seating on low retaining walls, around fire pits, or along garden edges.
Regardless of the application, proper installation is critical. From preparing a level, stable base to securing each cap in place, every step must be executed with precision. Following best practices ensures that caps and tops remain both functional and visually appealing for years to come.
Why Concrete Should Be Your Top Choice for Caps
Selecting the right material for your caps and tops is essential for achieving both long-lasting durability and a visually appealing finish. While stone and concrete are the most popular choices, concrete offers unmatched versatility—able to replicate the natural beauty of stone while also delivering sleek, modern design options.
By choosing concrete caps or concrete tops, you gain a material that not only withstands the elements but can also be customized to match your exact style and project needs.

Whether used for retaining walls, seating areas, pillars, or outdoor kitchen surfaces, concrete tops and caps deliver a stylish, durable, and budget-friendly solution for any hardscaping project.
Preparing for a Concrete or Stone Cap Installation
Before you begin installing your concrete or stone caps, proper preparation is essential. Skipping the planning phase can lead to poor fit, instability, and costly repairs down the road.
The process begins with assessing the site, confirming compatibility, taking accurate measurements, and gathering the necessary materials and tools.
1. Assess the Installation Area
Start by carefully evaluating the area where the cap or top will be placed. The surface should be level, stable, and free from debris that could compromise the installation.
- Base Stability: Walls, fire pits, outdoor kitchen counters, or columns should have a solid gravel base for proper drainage and long-term stability.
- Structural Soundness: If working with a stone or concrete block wall, ensure it’s in good condition and able to support the weight of the cap.
A thorough assessment at this stage ensures you’re building on a strong foundation.
2. Confirm Structural Compatibility
Before moving forward, verify that the existing structure is suitable for stone or concrete caps.
- Shape and Fit: Make sure the wall or pillar form works with the size and style of cap you’ve selected. Most caps require a slight overhang, especially when intended for seating.
- Load Capacity: Check that walls and columns are level, stable, and capable of handling the added weight.
Soil Conditions: For taller walls (over four feet) or heavy load-bearing designs, soil reinforcement may be necessary. In such cases, consult an engineer or experienced hardscaping professional.
3. Measure for Accuracy
Accurate measurements are key to selecting the right-sized caps or tops.
- Measure the length and width of the wall or pillar in linear feet.
- Calculate the total square footage needed.
- Use coarse sand to level the surface before placement.
- Double-check that each cap or top will fit snugly on the prepared surface.
Taking the time to assess, confirm, and measure properly ensures your concrete or stone cap installation will be stable, visually appealing, and build.
4. Purchase the Right Number of Caps or Tops
Once you’ve taken accurate measurements of your wall or pillar, determine how many concrete caps or stone caps you’ll need for the installation.
- Order Extra: Always purchase slightly more than your exact estimate. Extras can account for cutting mistakes, damage during installation, or adjustments needed for curved walls, uneven edges, or slight width variations along a straight wall.
- Seamless Appearance: Matching the number and style of caps to your structure’s dimensions ensures a clean, continuous look that enhances the overall visual appeal.
5. Gather the Necessary Materials and Tools
Before beginning your cap installation, assemble all required materials and tools to ensure the process goes smoothly.
Essential Tools:
- Masonry trowel
- Level
- Rubber mallet
- Tape measure
- Safety gloves
- Safety goggles (especially if cutting)
- Concrete saw (for fitting wall caps to size)
- Caulking gun (for adhesive or mortar application)
- Wheelbarrow (for mixing mortar)
- Mixing paddle (for blending mortar)
- Masonry brush (for cleaning surfaces)
- Hammer drill (if mounting to a concrete wall)
- Masonry screws or anchors (if extra securing is needed)
Materials:
- Concrete adhesive or mortar (check manufacturer recommendations for the correct type and amount)
Pro Tip: Many suppliers of concrete caps and tops can help you calculate the right amount of adhesive or mortar based on your specific project size and design.
