Product 01 · General purpose

HRC 32.5N

General purpose cement for everyday construction — the bag that carries most of a build, from foundation to finish.

50 kgFly ash basedSANS 50197-1

Scroll

Where it works

One bag, most of the site

32.5N is the general purpose grade. It handles the structural and flatwork side of a build rather than being tuned for a single trade, which is why it is usually the bag ordered by volume.

Bricklaying

Everyday brick and block work across walls and structure.

Concrete slabs

Ground slabs and suspended work where strength gain matters.

Foundations

Footings and strip foundations carrying the load of the build.

Driveways

Hardstanding and driveways that take vehicle traffic.

Why crews pick it

Predictable on site

Grade	HRC 32.5N Eco
Type	General purpose cement
Base	Fly ash based
Standard	SANS 50197-1:2013
SABS permit	11548/18099
Bag	50 kg

Low porosity

Denser and more impermeable, which is what gives it its resistance to chemical attack.

Superior workability

Cement extenders mean less water for a cohesive mix, and cleaner finishing.

Lab tested daily

Our on-site lab tests bags every day, so strength development stays predictable.

Product 02 · Masonry

HRC 22.5X

Masonry cement built for mortar and plaster — designed around the trowel rather than adapted to it.

50 kgMasonry cementSANS 50413-1

Scroll

Where it works

Made for the trowel

22.5X is a masonry cement, formulated for the jobs where handling and finish matter more than structural strength gain: bedding brick and laying plaster.

Bricklaying mortar

Mortar beds that stay workable and grip the brick properly.

Plaster

Internal and external plaster with an even, consistent surface.

Screeding

Floor screeds that level cleanly and cure to a consistent finish.

Why plasterers pick it

Cleaner off the board

Grade	HRC 22.5X Core
Type	Masonry cement
Use	Mortar, plaster and screeding
Standard	SANS 50413-1:2014
SABS permit	11548/18098
Bag	50 kg

Smooth application

Works cleanly off the trowel, so plasterers spend less time fighting the mix.

Strong adhesion

Grips brick and block properly, for mortar beds and render that stay put.

Consistent finish

An even surface across a wall, without patchy texture between batches.

Coming soon · Tile adhesive

HRT Tile Adhesive

Four cement-based adhesives to stand alongside the cement — ceramic and porcelain, each in an eighteen-hour rapid set and a twenty-four hour standard set.

20 kgFour gradesInterior & exterior

Scroll

01 · Rapid set

HRT 18 Ceramic

A rapid-setting adhesive for ceramic wall and floor tiles, inside and out. Six hours to initial set and eighteen to final, so a wall tiled in the morning can be grouted the next day.

Max tile size: 300 × 600 mm
Initial set: ~6 hours
Final set: ~18 hours
Pot life: ~4 hours
Grouting: ~18 hours

02 · Rapid set

HRT 18 Porcelain

The same eighteen-hour set, formulated for the low absorption of porcelain and the extra grip large formats need. Takes tiles up to 600 × 600 mm.

Max tile size: 600 × 600 mm
Initial set: ~6 hours
Final set: ~18 hours
Pot life: ~4 hours
Grouting: ~18 hours

03 · Standard set

HRT 24 Ceramic

The general purpose grade of the range. A longer, more forgiving working window — eight hours of pot life — for everyday ceramic wall and floor work.

Max tile size: 300 × 300 mm
Initial set: ~12 hours
Final set: ~24 hours
Pot life: ~8 hours
Grouting: ~24 hours

04 · Standard set

HRT 24 Porcelain

High-strength porcelain adhesion on a twenty-four hour set, with the same eight-hour pot life. For porcelain up to 300 × 450 mm.

Max tile size: 300 × 450 mm
Initial set: ~12 hours
Final set: ~24 hours
Pot life: ~8 hours
Grouting: ~24 hours

Common to the range

Same bag, same mix

Every grade is a 20 kg bag mixed to roughly five litres of clean, cool water. What changes between them is the set time and the tile the adhesive is rated to carry.

Bag size20 kg
Water~5 litres
Open time~20 minutes
Correction~20 minutes
Thickness3–20 mm
Apply at5–30 °C

Not on sale yet — dates to be confirmed. Technical figures are laboratory values at approximately 23 °C and 50% relative humidity; actual setting, open and working times vary with temperature, humidity, substrate porosity and site conditions.

What we make

Two grades, no filler

Rather than a long catalogue, we make the two bags that cover the work: a general purpose cement for structure and flatwork, and a masonry cement for mortar and plaster. Both ship as 50 kg bags.

HRC 32.5N

General purpose — bricklaying, slabs, foundations, driveways and general building.

See the 32.5N

HRC 22.5X

Masonry — bricklaying mortar and all plaster applications.

How we work

Built around the site

Our mission

To supply cement products that exceed industry standards, backed by unmatched competence, reliable service and a commitment to the success of every project we support.

Our vision

To be the most trusted cement brand in South Africa, recognised for our integrity and contribution to building a stronger, better future for generations to come.

Reliability first

Cement is only as good as its consistency. Ours is made so the bag a crew opens on Friday behaves like the one they opened on Monday.

Honest pricing

We price for real site budgets. Affordability should not mean accepting a bag that lets you down.

Local conditions

Formulated for South African sand, water, weather and working methods, because that is where every one of our bags ends up.

Certification

SABS approved, both grades

Hard Rock Cement (Pty) Ltd holds SABS permits to apply the certification mark on both products, issued under the Standards Act and accredited by SANAS. Our on-site lab tests every batch daily.
