Landscape projects often combine visual design with structural demands. A patio has to look finished while standing up to foot traffic and weather. A retaining wall has to complement the property while holding back soil. Walkways, garden borders, drainage features, outdoor kitchens, and other hardscape elements all depend on choosing materials that match the job.

That is why experienced landscapers pay close attention to the masonry supplies behind the finished design. Stone, block, mortar, reinforcement, and drainage materials each serve a different purpose, and using the right combination can improve both appearance and long-term performance. I-10 Building Materials supplies contractors throughout the San Antonio area with a large masonry inventory, custom stone fabrication, fast rebar turnaround, and same-day service availability.

1. Flagstone for Patios, Walkways, and Outdoor Living Areas

Flagstone is one of the most versatile materials available for landscape construction. Its natural shapes, color variations, and textured surfaces work well in patios, walkways, garden paths, pool areas, and decorative features where the hardscape is meant to feel integrated with the surrounding landscape.

I-10 Building Materials carries flagstone options that include sandstone, limestone, slate, quartzite, and travertine. Different stone types can create very different looks, from rustic Hill Country-inspired spaces to cleaner, more contemporary outdoor areas.

Flagstone also gives landscapers flexibility when an installation needs to follow an irregular footprint. Rather than relying only on uniform units, crews can arrange stone around planting beds, curves, steps, and other site features.

For projects that require specific dimensions or unusual shapes, I-10 Building Materials also offers custom stone fabrication. That service can help landscapers source pieces that fit the design rather than modifying the entire design around standard-size material.

2. Web Stone and Blocks for Retaining Walls

Retaining walls are among the most structurally demanding elements in a landscape. They are used to manage grade changes, create usable space on sloped sites, define planting areas, and help control erosion. The material needs to provide a stable wall system while fitting the visual style of the property.

I-10 Building Materials offers web stone designed for retaining walls and garden features. The interlocking format helps create a consistent wall system while providing the appearance of masonry stone. The company also carries bricks and blocks for a broader range of landscape and masonry applications.

Material selection becomes especially important when wall height, soil conditions, drainage, or site loads increase. Landscapers may need different block sizes, reinforcement, base materials, or drainage components depending on the project.

A supplier with a broad stock of masonry supplies makes it easier to coordinate those components instead of sourcing each part from a different location.

3. Mortar, Cement, and Grout for Bonded Masonry

Stone and brick receive most of the visual attention, but the material holding masonry together is just as important. Mortar and cement are used in many bonded installations, including walls, stone features, outdoor fireplaces, borders, and other landscape structures.

I-10 Building Materials stocks mortar and cement along with grout and other masonry materials. The appropriate product depends on the masonry units, exposure conditions, and structural requirements of the project.

This is an area where using the correct material matters more than simply choosing the strongest mix available. Different masonry applications can require different mortar characteristics, so contractors need products suited to the units and conditions they are working with.

According to Global Market Insights, the North American masonry cement market was valued at approximately $620 million in 2026 and is projected to grow at about a 4.0% compound annual growth rate through 2035. The report points to housing, renovation, infrastructure rehabilitation, and continued masonry use as important parts of regional demand.

For landscapers, dependable access to mortar and cement helps keep masonry work moving without treating the bonding material as an afterthought.

4. Rebar and Wire Mesh for Reinforced Landscape Features

Not every hardscape element needs reinforcement, but concrete and structural landscape features often depend on steel reinforcement to help them handle loads and movement. Rebar and wire mesh may be used in footings, concrete slabs, reinforced walls, steps, and other elements that support heavier landscape construction.

I-10 Building Materials stocks rebar in multiple sizes along with wire mesh and other foundation supplies. Its foundation inventory also includes concrete mix and additives, waterproofing materials, drainage solutions, expansion joints, anchor bolts, and fasteners.

The company emphasizes fast turnaround on rebar orders, which can be particularly useful when a project schedule depends on having reinforcement ready before concrete placement or wall construction begins.

Landscapers handling outdoor kitchens, masonry walls, large steps, structural slabs, or other permanent features benefit from coordinating reinforcement with the rest of their masonry supplies early in the project. That helps reduce jobsite delays and keeps structural materials aligned with the planned build sequence.

5. River Rock and Aggregates for Drainage and Landscape Detail

Some of the most useful masonry materials in a landscape are not part of a wall or patio at all. River rock and aggregates can serve both visual and practical roles in outdoor projects.

I-10 Building Materials offers river rock in multiple sizes, colors, and finishes. The company identifies uses such as dry creek beds, water features, garden borders, decorative ground cover, erosion control, and drainage applications.

River rock can be especially effective when landscapers want drainage areas to look intentional rather than purely functional. A swale, dry creek, or transition around a drainage feature can become part of the overall design when the stone color and size are selected carefully.

Bulk aggregates can also support base preparation and other project needs. Proper base and drainage planning are important for patios, walkways, walls, and other hardscape installations because the finished surface is only as reliable as the layers supporting it.

6. Custom-Cut Stone for Details That Standard Pieces Cannot Solve

Many landscape projects include at least one detail that does not fit a standard material size. Steps may need a specific cap. A wall may turn around an unusual corner. A patio may require a clean transition around a column, pool edge, or built-in feature.

Custom-cut stone gives landscapers more control over those details. I-10 Building Materials offers custom stone fabrication and a wide selection of stone shapes, including rectangular blocks, flagstone slabs, decorative veneer, cut stone pavers, irregular fieldstone, cobblestones, ashlar patterns, and mosaic pieces.

Using fabricated pieces where appropriate can create cleaner transitions and more intentional-looking finishes. It can also reduce the need to force a standard piece into a space where it does not fit well.

For contractors, custom fabrication can be especially useful when a new landscape element needs to coordinate with existing stonework or when the design calls for a particular size, profile, or pattern.

Choosing Masonry Supplies as a Complete System

Durable hardscapes rarely depend on one product alone. A retaining wall may involve stone or block, base material, drainage components, reinforcement, and mortar. A flagstone patio may require stone, base materials, joint materials, and custom-cut pieces around edges or built-in features.

Thinking about masonry supplies as a complete system helps landscapers plan for both the visible finish and the materials underneath it. It also makes ordering more efficient because quantities, reinforcement, drainage, and specialty pieces can be coordinated before work begins.

I-10 Building Materials has supplied masonry professionals in San Antonio since 1985 and maintains a large inventory of bricks, blocks, mortar, cement, stone veneer, rebar, wire mesh, concrete admixtures, tools, flagstone, river rock, aggregates, and specialty stone products. The company is also a member of the San Antonio Masonry Contractors Association and the Texas Masonry Council.



Source the Right Materials for Long-Lasting Landscape Work

Landscapers rely on durable materials because outdoor projects have to perform through weather, moisture, soil movement, foot traffic, and everyday use. Flagstone, retaining-wall stone, mortar, reinforcement, river rock, and custom-cut stone each solve a different part of that challenge.
