Use it to plan your next build with confidence.
Building in Antigua is not like building anywhere else. You are working in a salt-air environment, on a small island where materials arrive by sea, during a climate that throws a hurricane season at you every single year from June through November. Getting your antigua concrete services right is not just a budget question; it is a structural safety question.
Yet if you search online for practical advice on sourcing concrete blocks or ready-mix concrete in Antigua, you will find almost nothing. A sparse directory entry here, a Facebook page there. No guide, no pricing benchmarks, no comparison of suppliers.
This post fixes that. Whether you are a homeowner starting a self-build in St. Philip, a renovation contractor working in English Harbour, or a villa developer in St. Mary, this is your complete 2026 reference for sourcing concrete products and services in Antigua and Barbuda.
What Is Antigua Concrete Services?
Antigua Concrete Services is a Saint John's-based concrete contractor that provides ready-mixed concrete and related services for both residential and commercial construction projects across Antigua. With around 350 followers on their Facebook page and a Indoconnex business profile confirming island-wide operations, they serve the full spectrum of local build types.
Think of Antigua Concrete Services as the contractor side of the concrete supply chain. They pour, place, and finish concrete on site. That is different from a block manufacturer or a bulk aggregate supplier. Understanding where they fit in the broader ecosystem helps you know who to call and when.
For many self-build homeowners, the confusion starts here. Do you call a concrete services contractor? Do you call a masonry products manufacturer? Do you need a pumping service? The answer usually depends on whether you are building walls (block), laying a slab or column (ready-mix), or tackling a poured structure in a tight or elevated location (pumping). All three products often come from different suppliers.
Ready-Mix Concrete vs. Concrete Blocks: Which Do You Need?
Ready-mix concrete is a pre-batched liquid mixture delivered by drum truck to your site, ready to pour directly into formwork. Concrete blocks are solid or hollow precast masonry units you stack and mortar into walls. You almost certainly need both for any new residential build in Antigua, just at different stages of construction.
Ready-mix concrete is manufactured at a central batching plant where cement, aggregate, sand, and water are combined in controlled proportions. It arrives at your site in a rotating drum truck, still workable, and gets poured directly into your formwork for foundations, floor slabs, ring beams, columns, and lintels.
The main advantage is consistency. The water-to-cement ratio is controlled in the plant, which means a more predictable compressive strength. For structural pours, that matters enormously. Inconsistent hand-mixed concrete can have weak spots you cannot see until a wall cracks or a slab settles.
Concrete blocks are used after the slab is down. They are the walls of your home. Because they are precast, they are ready to lay immediately without waiting for a curing period on site. This makes them ideal for the Caribbean, where a sudden downpour during a pour can compromise on-site mixed concrete.
A standard Antiguan build follows a clear sequence: ready-mix slab, then block walls, then ready-mix ring beam at the top, then roof. Each material has its moment. The question is which suppliers in Antigua can reliably deliver each.
6-Inch vs. 8-Inch Blocks: Which One for Your Build?
In Antigua, 6-inch concrete blocks are typically used for interior partition walls and non-load-bearing applications. 8-inch blocks are the standard for external structural walls, foundations, and any wall that carries a roof load or has to resist wind pressure during a hurricane. When in doubt, build in 8-inch.
The "6 vs 8" question comes up on almost every residential build in Antigua. Here is the practical breakdown.
A 6-inch (150mm) hollow concrete block is lighter, cheaper per unit, and fast to lay. It is appropriate for dividing rooms inside a building where structural load is already carried by the external walls and ring beam. If you are extending a bathroom, creating a storeroom, or building a boundary garden wall, a 6-inch block can work.
An 8-inch (200mm) block is heavier and costs more per unit, but it gives you the wall thickness to properly fill the cores with rebar and concrete grout. That filled-core reinforced wall is what hurricane-resistant Caribbean construction depends on. A structural rebar should extend up from the slab at 16-inch centres through the block cores, which are then filled with concrete to the ring beam above. Without sufficient wall thickness, you cannot complete that detail correctly.
For St. Philip parish projects, where exposed east-coast wind exposure is a real factor, the 8-inch structural block is non-negotiable on any external wall.
Concrete Pumping: When Do You Actually Need It?
Concrete pumping uses a truck-mounted or static pump to push ready-mix concrete through steel and rubber pipes to locations a drum truck cannot directly reach. You need pumping when your pour is elevated (upper floors, ring beams), in a confined courtyard, on a steep hillside site, or anywhere a drum truck cannot position safely beside the formwork.
Antigua's topography creates plenty of situations where pumping is necessary. Hill-side villas in St. George and St. Paul, narrow plots in central St. John's, pool decks on elevated terraces around English Harbour. In each case, trying to wheelbarrow ready-mix from a drum truck parked on the road is slow, wastes concrete through spillage, and allows the mix to begin setting before it reaches the pour point.
A concrete pump solves this. Boom pumps use a remote-controlled hydraulic arm to place concrete precisely at height or over obstacles. Line pumps work through steel and rubber pipes laid horizontally, covering up to 150 metres of distance along ground level. Both keep the concrete moving continuously, which preserves workability and structural consistency right through to the point of pour.
Not every concrete services contractor in Antigua runs pumping equipment. If your site has access challenges, confirm pumping capability before you commit to a supplier. It is a capability that Antigua Masonry Products Ltd is known to offer alongside their ready-mix supply.
Most ready-mix suppliers require a minimum order, typically one to two cubic metres, before they will dispatch a drum truck. For very small pours, a hand-mix on site may actually be more practical. For anything structural, particularly a ring beam, column, or full slab, ready-mix is worth the delivery cost.
Who Are the Main Concrete Suppliers in Antigua?
This is the section that no other online guide has attempted. Here is an honest comparison of the principal concrete supply players in Antigua, based on available public information.
Antigua Masonry Products Ltd
Antigua Masonry Products is the island's largest and longest-established concrete products manufacturer. Over 50 years of operation has given them a production scale and product range that no other local company currently matches. Their range includes concrete blocks in multiple sizes, ready-mix concrete in high-strength mixes, aggregates, manufactured sand, pumping services, and ornamental concrete products such as balustrades and paving stones. If you need volume block supply for a full residential build, Antigua Masonry Products is the starting point.
Antigua Concrete Services
Antigua Concrete Services operates primarily as a concrete contractor rather than a manufacturer. They serve both residential and commercial clients. Their strength is the service side: placing, finishing, and managing poured concrete on your specific site. For a homebuilder who has sourced their ready-mix but needs a skilled crew to complete the pour and finish, this is the kind of operator you need.
CreteWorks Construction
CreteWorks Construction was founded in 2020 and has established itself as a project-led concrete contractor with a focus on residential and commercial builds. They completed the Ocean Breeze Apartments, a multi-story hurricane-resistant residential complex, and have undertaken public works including road construction, bridges, and drainage systems. With reported revenues of approximately $15 million in 2023, they operate at a scale suited to commercial and estate-level projects rather than individual self-builds. If you are developing a villa complex, a boutique hotel, or commercial premises in Antigua, CreteWorks is a credible option for a design-and-build or turnkey concrete contract.
For a homebuilder tackling a single residential plot, Antigua Masonry Products for block and aggregate supply combined with a local concrete services contractor for the pour and finish is typically the more cost-effective structure. For a developer running multiple units or a complex commercial project, a firm like CreteWorks can manage the entire concrete scope under one contract.

What Does Concrete Cost in Antigua? An EC$ Pricing Guide
Pricing for concrete products in Antigua is not published in any public price list. Every supplier quotes based on current aggregate costs, shipping, and order volume. That said, there are credible benchmarks you can use to sense-check a quote before you commit.
Caribbean construction materials cost 20 to 40 percent more than US mainland prices due to import dependence and shipping costs. Cement, aggregate, and admixture prices have risen 15 to 25 percent since 2022. Local manufacturing of blocks helps offset some of this, which is why buying from a local block manufacturer like Antigua Masonry Products is meaningfully cheaper than importing finished products.
As a rough EC dollar guide for 2026, consider the following typical market ranges. These are reference points only. Always get a written quote from your supplier.
Concrete blocks: Standard 6-inch hollow blocks typically run in the range of EC$4 to EC$6 per block in the Eastern Caribbean market for standard construction grade units. 8-inch structural blocks carry a small premium over 6-inch units, typically 20 to 30 percent more per block. Buying in pallet quantities (usually 90 to 120 blocks per pallet) reduces your per-unit cost compared to purchasing individual blocks.
Ready-mix concrete: Priced per cubic metre. The total cost includes the mix, the drum truck delivery, and the discharge time on site. Budget for a meaningful premium above what you might pay in the US or UK; island delivery logistics and import costs for cement feed directly into the price. Confirm minimum order quantities with your supplier before scheduling a pour.
Concrete pumping: Quoted as a day rate or a per-cubic-metre rate depending on the contractor. Access difficulty, boom or line pump selection, and travel distance from the plant all affect the final number. Get quotes from at least two operators and confirm they will inspect your site access before the scheduled pour day.
Delivery surcharge: Deliveries to the eastern parishes including St. Philip, St. Peter, and parts of St. George may carry additional delivery charges compared to St. John's central area. Factor this into your project budget upfront.
If you are financing your build through a local institution, the Community First Credit Union offers construction loans with as little as a 5 to 10 percent cash deposit for eligible members, with DCA-approved plans required. Factor material costs into your typed estimate before submitting.
Building Through Hurricane Season: Why Concrete Is Urgent Right Now
Hurricane season in Antigua runs from June through November. It is also, somewhat counterintuitively, the busiest period for concrete block demand. Two things drive this. First, homeowners and contractors want to get structural reinforcement completed before peak storm activity arrives in August and September. Second, post-storm rebuilding creates demand spikes immediately after any significant weather event.
Reinforced concrete block construction is the standard for hurricane-resistant building throughout the Caribbean. When masonry walls are properly filled with rebar and concrete grout from slab to ring beam, the wall becomes part of a structural system that can resist hurricane-force wind loads. The key detail is that the blocks must be load-bearing 8-inch units, the rebar must be continuous from the slab up through the ring beam, and the ring beam itself must be poured in-situ with ready-mix.
Cutting corners on block specification during hurricane season is not a money-saving decision. Post-hurricane assessments in the Caribbean consistently show that 60 to 70 percent of buildings in affected areas sustain moderate to severe structural damage. Rebuilding after a storm costs three to five times more than building correctly from the outset. Concrete block, properly reinforced, remains the most cost-effective structural solution available to Antiguan homebuilders.
If you are in a parish with elevated wind exposure, particularly the eastern coast communities in St. Philip or the open northern slopes of St. Peter, the structural specification matters even more. Talk to a local architect or structural engineer before finalising your block and mix choices. Firms like D Benjamin Architects work across all parishes and can advise on DCA-compliant structural specifications for your plot.
Drainage prep is also a concrete-season issue. Before peak storm months, contractors across Antigua focus on culverts, drainage channels, and retaining wall repairs. These projects are almost always ready-mix and pumping work. If you have drainage infrastructure on your property that needs work, the period before peak hurricane season is the right time to schedule it.

Conclusion
Concrete is the backbone of virtually every building in Antigua. The island's hurricane exposure, salt-air environment, and import-dependent materials market make choosing the right products and the right suppliers a genuinely high-stakes decision. Getting it wrong costs you money; getting it very wrong costs you a structure.
Three things stand out from this guide. First, ready-mix concrete and concrete blocks are different products from different supply chains. You need to plan both separately. Second, for external structural walls anywhere in Antigua, 8-inch blocks with rebar and core fill are the right call, not just a nice-to-have. Third, hurricane season demand is real and it peaks fast. If you are planning a build or a reinforcement project, lock in your supplier and your delivery dates early.

Frequently Asked Questions
What is the difference between Antigua Concrete Services and Antigua Masonry Products?
Antigua Concrete Services operates primarily as a concrete contractor, placing and finishing poured concrete on site for residential and commercial clients. Antigua Masonry Products Ltd is a manufacturer with over 50 years of operation that produces concrete blocks, ready-mix concrete, aggregates, and manufactured sand for the entire island. Many Antiguan builds use Antigua Masonry Products as a supply source and engage a concrete services contractor separately for the placement work.
Do I need a concrete pump for my Antigua house build?
Not necessarily for every stage, but for upper-level ring beams, elevated terraces, hillside sites, and confined urban plots, a concrete pump is the practical solution. Without pumping, trying to wheelbarrow ready-mix concrete across a site allows the mix to begin setting before it reaches the pour point, which compromises structural strength. Confirm your site conditions with your concrete contractor before the pour date.
What is the best concrete block for hurricane-resistant construction in Antigua?
An 8-inch structural hollow block from a reputable local manufacturer, used with rebar and core fill poured with ready-mix concrete, is the standard specification for hurricane-resistant masonry walls in the Caribbean. The rebar must run continuously from the foundation slab through every block core and into the cast-in-place ring beam above. Using a 6-inch block on external walls or skipping core fill are the two most common corners cut, and both compromise structural integrity significantly.
How much concrete do I need for a typical Antiguan house slab?
The volume depends on slab thickness and footprint. As a general rule, a standard 4-inch (100mm) slab for a 1,000 square foot home requires approximately 9 to 10 cubic metres of ready-mix concrete. Most suppliers in Antigua require a minimum order of at least one to two cubic metres and charge by the cubic metre. A structural engineer or experienced local contractor can calculate your specific volume from your DCA-approved plans.
When is the best time to order concrete blocks in Antigua?
Demand spikes in the early part of hurricane season (June and July) as contractors race to get structural work completed before peak storm months. If you are planning a new build or a structural upgrade, ordering your blocks and scheduling your ready-mix delivery in April or May gives you the best chance of securing supply and avoiding lead time delays. Post-storm periods (typically late September through November) see a second demand spike as rebuilding begins.
