HC&D

What HC&D does

HC&D, LLC is a privately held, vertically integrated construction materials manufacturer operating exclusively in the Hawaiian islands. The company produces crushed stone aggregate, manufactured sand, mason sand, and a portfolio of ready-mix concrete products, including specialty formulations such as Self Consolidating Concrete (SCC), Controlled Low Strength Material (CLSM) flowable fill, high-slump concrete, corrosion-inhibiting concrete, fiber-reinforced concrete, and integral colored concrete available in over 100 colors via a partnership with Master Builders Solutions. Operations are anchored by two long-established quarries — Kapaa Quarry on Oahu (Kailua) and Camp 10 Quarry on Maui (Puunene) — each with 50+ years of continuous aggregate supply, supplemented by a Sand Island distribution yard in Honolulu. The business serves general construction contractors, utility/infrastructure contractors, architects, and aggregate buyers across residential, commercial, and infrastructure projects (from residential patios to high-rise condominiums and freeway decks).

HC&D generates revenue through direct unit-priced sales of aggregates, sand, and ready-mix concrete, with published 2025 and 2026 price schedules differentiated by island (Oahu and Maui) and product line. The go-to-market model is hybrid: phone-based inside sales and dispatch for transactional orders, layered with field sales supervisors (Bentley Pai on Oahu, Kevin Abulon on Maui) handling larger commercial and project-based accounts. Customers place orders via dedicated sales and dispatch numbers, with daily and future-order lines on each island; no e-commerce or online transactional ordering is offered. The company also publishes a Ready-Mix Estimator tool on its website to help buyers size orders. Marketing channels are limited to a product website with downloadable price-list PDFs, organic social media (Instagram, Facebook, LinkedIn), and recruitment advertising in local publications.

The company is led by President Eileen L. Mori-Mishina and CEO Wade H. Wakayama, with Rick Volner Jr. as SVP of Operations and Glenn H. Okuno as VP of Finance. The Terms of Service page is titled "Ameron Terms of Service," indicating a historical connection to the Ameron brand, though no current parent company is identified. The legal entity is HC&D, LLC, with 101–250 employees and headquarters in Honolulu, Hawaii.

Core offering

HC&D produces and sells construction aggregates (crushed rock, manufactured sand, mason sand, base course, select borrow) and ready-mix concrete from its Kapaa Quarry on Oahu and Camp 10 Quarry on Maui, supplying the Hawaiian islands' construction industry for over 50 years. The ready-mix concrete line includes specialty mixes such as Self Consolidating Concrete (SCC), Controlled Low Strength Material (CLSM) flowable fill, high-slump concrete, corrosion-inhibiting concrete, fiber-reinforced concrete, and integral colored concrete in over 100 colors. Customers place orders by phone for pickup or delivery to jobsites across Oahu and Maui.

Product overview

HC&D operates as a single-line construction materials supplier rather than a software platform, delivering two core product lines that are sold alongside each other on both Oahu and Maui: Aggregates (rock and sand drawn from the Kapaa Quarry on Oahu and Camp 10 Quarry on Maui) and Ready Mix Concrete (offered in multiple specialty mixes such as Integral Colored Concrete, High-Slump Concrete, Self Consolidating Concrete (SCC), Controlled Low Strength Material (CLSM), Corrosion Inhibiting Concrete, and Fiber Reinforced Concrete). The Ready Mix Estimator serves as a supporting customer-facing tool that helps buyers size their concrete orders against the published price schedules for each island.

Scale indicators4 records

Recent moves5 records

Expansion highlights4 records

Broad incumbents

• CEMEX: Global building materials company producing cement, ready-mix concrete, and aggregates. Comparable ready-mix and aggregate product lines with specialty concrete variants, but operating on a global scale.
• Martin Marietta Materials: Major U.S. supplier of aggregates and heavy building materials. Comparable core product (aggregates) and customer base (construction contractors), but operating at continental scale rather than HC&D's island-focused model.
• Summit Materials: U.S. aggregates and ready-mix concrete producer with vertically integrated operations. Comparable vertical quarry-to-concrete model, though nationally diversified rather than concentrated on Hawaii.
• Vulcan Materials Company: Largest U.S. producer of construction aggregates and a major concrete supplier nationally. Comparable aggregate and concrete product mix, but operates on a mainland scale that dwarfs HC&D's two-island footprint.

Others

• Ameron Hawaii (historical entity): Historical predecessor brand referenced in HC&D's own Terms of Service as 'Ameron Terms of Service'. Previously a major Hawaii concrete and steel pipe producer; relevant as the corporate lineage underlying HC&D's current operations.

Direct peers

• Grace Pacific LLC: Hawaii-based construction materials and paving contractor producing aggregates, ready-mix concrete, and asphalt. Overlaps directly with HC&D on aggregate and concrete supply on Oahu and other islands.
• Hawaiian Cement: Hawaii's other major cement, concrete, and aggregate supplier with operations across multiple Hawaiian islands. Directly competes with HC&D on ready-mix and aggregate supply in the same local market.
• Maui Concrete & Aggregate (dba Ghris-Mokulani): Hawaii-based producer of ready-mix concrete and aggregates with operations overlapping HC&D's Maui market. Directly comparable product offering and local Hawaii construction customer base.
• West Hawaii Concrete: Ready-mix concrete producer serving the Big Island of Hawaii. Comparable product offering (ready-mix) and customer base (Hawaii construction contractors), though geographically distinct from HC&D's Oahu/Maui footprint.

Regional players

• T. Iida Contracting, Ltd. Hawaii-based heavy civil and site work contractor that also produces and supplies aggregates. Comparable aggregate supply and Hawaii construction contractor customer base, though primarily a contractor rather than a pure materials supplier.
