Cement Brands in Jamaica Compared: What Actually Matters for Your Mix

TL;DR: Which Cement to Buy

Short answer: the locally made bag in Jamaica is Carib Cement Plus, made by Caribbean Cement Company Limited, a CEMEX subsidiary, and sold in 42.5kg bags. Imported cement fills the gap when local supply is short, as it was in mid-2026. There is no fixed price to quote this year, so call Malcolm's Hardware on (876) 926-3611 before you buy.

• 42.5kg is a bag weight, not a grade. Carib Cement Plus comes in 42.5kg bags, according to Carib Cement's product page.
• Carib Cement is the local default. Made in Jamaica from 100% Jamaican raw materials, according to Carib Cement.
• Imported cement is the backup. The Government approved 660,000 tonnes of cement imports in 2026 (JIS). Read the type and standard on any bag and check it's dry.
• Fresh beats fancy. Buy from a store that moves stock quickly, so the cement pours like flour.
• Mix ratio matters more than brand. 1:2:4 by volume is a common nominal mix for structural concrete, but your engineer's specified mix controls.
• Check the price on the day. Call ahead, and ask about bulk pricing when you're buying for a slab pour.

The rest of this guide covers why supply was tight, what's actually on the shelf, set time, storage, and the mix ratios that separate a slab that lasts from one that cracks.

Why Cement Was Hard to Find in 2026

If you struggled to find cement this year, it wasn't your imagination. Minister of State Delano Seiveright told the House in June 2026 that the pressure came from operational problems at Caribbean Cement Company, linked to bad weather and equipment failures, and from extensive warehouse damage at Buying House Cement Limited after Hurricane Melissa (JIS, June 2026).

In response, the Ministry approved import permits for 100,000 tonnes for Caribbean Cement and 70,000 tonnes for Buying House Cement. Total approvals reached 660,000 tonnes: 170,000 tonnes already authorised, plus a further 490,000 tonnes approved by Cabinet under Decision No. 24/26 (JIS, June 2026). Caribbean Cement also pushed its own output: production rose 50% month-on-month in May 2026, and sales hit a record 111,000 tonnes that month. The CEMEX group also added 23,900 tonnes of imports to its Jamaican supply (Global Cement, June 2026).

On price, the Prime Minister called on Carib Cement to reduce its prices, and said the Government had increased import quotas to help stabilise prices and safeguard supply (JIS). For you at the counter, that means two things:

• Check the price on the day you buy. The Consumer Affairs Commission's outlet price tool publishes hardware price surveys by parish, the latest dated June 2026. Call (876) 926-3611 ahead before you travel.
• Buy ahead of a pour, not on the morning of it. When supply is tight, a slab that needs 10 bags and finds 6 ends up with a cold joint. Get the whole order together before the mixer turns.

42.5kg Bags and Strength

People see 42.5 on a bag and assume it's a strength grade. Carib Cement's product page lists two products: Carib Cement Plus, sold in 42.5kg bags, 1,500kg jumbo bags and bulk tankers, and Carib HE (High-Early), sold only in 1,500kg jumbo bags and bulk tankers (Carib Cement). So a locally made bag of Carib cement is Carib Cement Plus, and its 42.5kg is the weight of the bag. A weight tells you nothing about strength.

Read the whole label rather than the biggest number on it. What that means for your job:

• Structural work (slabs, columns, beams, footings): use the cement type your engineer or mason specified, and don't swap it to save a little per bag.
• Non-structural work (plaster render, floor screed, low-load blockwork mortar): general-use bagged cement is the usual choice.
• Big pours needing early strength: Carib HE comes in jumbo bags and bulk only, so it's a contractor or batching-plant order, not a counter purchase.

The Cement You Can Buy, Compared

Here is what you'll realistically find in Kingston, and how the options differ. Availability shifts with supply, so treat this as a working guide rather than a stock list.

CEMEX isn't a separate import competing with Carib: it's Carib Cement's parent company (JIS). Carib Cement Plus is the locally made option, and imported cement is the backup when the local shelf is thin. What separates a strong pour from a weak one is the right cement for the job, bought fresh, mixed and cured properly.

Set Time and Working Window

Plan the pour around the heat of the day.

What that means for you on site:

• Leave formwork and props to your engineer. They come out when the engineer says the concrete is strong enough, especially under suspended slabs and beams. If a job needs early strength, that is a specification for your engineer, and Carib HE is a jumbo-bag or bulk order, not a counter bag.
• Pour early. Start a big slab in the early morning rather than under the midday sun. Keep the mix in the shade until it goes in.
• Do not re-temper. Don't add water to concrete that has started to stiffen to make it workable again. Follow your supplier's or engineer's instructions on any water adjustment, and mix only what you can place in the working window.

Curing is the other half of set. Once placed, keep concrete damp for several days. Cover a slab with plastic or wet burlap and hose it down. Ask your mason how long to keep it damp for the job, whichever brand you bought.

Storage: Why Cement Goes Bad

Keep cement away from damp. A bag that sat in a damp shed for months is not the bag you paid for.

How to store it so it stays good:

• Off the floor. Stack bags on pallets or timber, never directly on a concrete floor that wicks moisture up into the bottom bags.
• Away from walls. Keep a gap so damp does not transfer from the wall into the stack.
• Covered and dry. A tarp over the stack in a dry, ventilated space. Not a leaky shed, not the open yard.
• First in, first out. Use older bags before newer ones so nothing sits long enough to spoil.

The field test: pick up a bag and squeeze it. Good cement flows and feels like flour. If you feel hard lumps that will not crush between your fingers, don't use that bag. For a slab or column, only use bags that pour freely. Buying fresh from a high-turnover store is the cheapest insurance you can buy on a build.

Mix Ratios That Actually Matter

You can buy the freshest cement on the island and still pour a weak slab if the ratio is wrong. The mix is where most of the strength lives. Here are common starting points, unless your engineer specifies otherwise:

The common mistake is too much water. A soupy mix is easier to place, so it is tempting. Add only the water the mix design or your mason calls for, and no more.

If you are pricing out a full project, the cement is just one line. Our breakdown of what a concrete slab costs in Kingston in 2026 covers sand, steel, and labour alongside the cement, and how long a small Kingston construction project should actually take sets expectations on curing and timeline.
