Choosing Terrazzo Tiles for Construction Projects: What to Check Before You Commit

When it comes to paving a pavement, a courtyard, or a walkway, most buyers start with the same question: how much does it cost per square meter? That question is reasonable, but it’s often asked too early. Terrazzo tiles that look identical and carry a similar price tag can differ significantly in specification, technical standard, and total delivered cost once you account for everything a project actually needs.

This article walks through the criteria that matter before terrazzo tiles ever make it onto a bill of materials — starting with the product itself, moving through the technical requirements and the relevant national standard, and finishing with how to translate all of that into an accurate cost estimate. It’s written for project owners, engineers, and contractors who need a defensible basis for a material decision, not just a quote.

What Are Terrazzo Tiles, and Where Are They Typically Used?

Terrazzo tile is a paving material with a decorative surface made from aggregate (stone or gravel) bound together with cement, then ground to a smooth, polished finish. A typical tile is built from a few layers: a cement binder that provides structural strength, an aggregate layer that creates the visible pattern, a face layer on multi-layer products, and a finished, ground surface.

Because of its durability and consistent appearance over time, terrazzo tile is commonly used for:

• Pavements
• Courtyards
• Internal walkways
• Public and communal areas with heavy foot traffic

Why the Listed Price Is Rarely the Full Story

One of the most common mistakes in early-stage budgeting is treating the quoted unit price as the final number. In practice, the unit price is only one component of the total delivered cost, which also includes:

• The actual quantity required, based on the coverage area
• Wastage during transport and installation
• Freight to the project site
• Loading and unloading costs
• The specific delivery terms agreed with the supplier

Two quotes with the same unit price can still produce very different total costs once these factors are added in — which is why comparing suppliers on price alone tends to be misleading.

A Change in Specification Changes the Quantity — and the Cost

Tile specification (dimensions and thickness) determines how much area a single tile covers, which in turn determines how many tiles a given project needs. Even a small deviation from the specified dimensions can shift the quantity required, and with it, the total material cost — regardless of whether the unit price stays the same.

Technical Documentation Should Be Verified Before Committing, Not After

For projects that require formal quality control — documentation for acceptance testing, handover, or warranty purposes — the applicable standard and supporting technical records should be confirmed as part of the selection process, not treated as paperwork to be sorted out later.

Technical Criteria Worth Checking Before You Order

Before any terrazzo product goes into a materials list, it’s worth checking it against the following:

Dimensions and thickness — length, width, thickness, consistency between individual tiles, and the manufacturer’s stated tolerance.

Compressive strength and load-bearing capacity — should match the intended use; an area with vehicle traffic requires a higher rating than a pedestrian walkway.

Abrasion resistance — particularly important for pavements and other high-traffic public areas.

Water absorption and suitability for outdoor conditions — relevant for any exposed installation, though specific thresholds should be checked against the product’s own documentation rather than assumed to be uniform across all terrazzo products.

Surface flatness and evenness — affects joint alignment, ease of installation, and the finished appearance.

Understanding TCVN 7744:2013 Before Selecting a Supplier

Among all the criteria above, checking a product against the relevant national standard offers the most objective basis for comparison — it doesn’t depend on how a supplier chooses to describe their own product.

What the Standard Covers

According to the Vietnam Standards and Quality Institute (VSQI), TCVN 7744:2013, titled “Terrazzo Tiles,” applies to cement-bound terrazzo tiles used for both interior and exterior paving. VSQI currently lists the standard as being in effect.

The standard addresses several groups of requirements, including dimensions and permissible tolerances, physical and mechanical properties, flexural strength, abrasion resistance, and other quality-related requirements. This article does not reproduce the detailed tables of technical values from the standard itself; readers who need exact figures should consult the original document.

Why “Terrazzo” as a Name Isn’t Enough

A common misunderstanding is assuming that because two products share the name “terrazzo tile,” they meet the same technical requirements. In reality, the name describes a category of material, not a certification. Two products with the same name can differ in construction, manufacturing process, and how closely they meet the standard. Buyers should ask suppliers to confirm the applicable standard against the documentation for the specific product being purchased, rather than assuming compliance from the product name alone.

A more detailed discussion of how this standard is applied in practice is available on the tiêu chuẩn gạch Terrazzo reference page.

A Practical Example: Khai Phong Terrazzo Tiles and TCVN 7744:2013

Which Product Has Supporting Documentation?

Based on the product documentation currently available, Khai Phong publishes an exterior terrazzo tile, two-layer construction, grade 1, in a 400 × 400 × 30 mm specification, along with the corresponding certification information for that specific product.

What a Compliance Certificate Actually Means for a Buyer

A product with a compliance certificate offers a few practical benefits: it gives buyers a documented basis for verifying suitability before the material is used on site, it supports the materials documentation required for project acceptance, it makes it easier to trace quality information later if needed, and it provides an additional reference point alongside price and delivery schedule.

That said, this certification information is tied to the specific product and specification published — it should not be read as meaning that every other terrazzo product from the same manufacturer automatically meets the same standard, unless separate documentation exists for each specific product line.

A Distinction Worth Making: Specification Is Not the Same as Certification

The 400 × 400 × 30 mm figure is a dimensional specification. It does not, on its own, mean the product meets TCVN 7744:2013. Whether a product complies with the standard needs to be confirmed separately, through documentation or test results — it cannot be inferred from dimensions alone.

From Technical Specification to Cost Estimate

Once a product has been confirmed as technically suitable, the next step is converting that specification into figures that can go into a cost estimate.

The general sequence is: confirm the exact specification first, then calculate the required quantity using Tile Quantity = Area × Coverage Rate (where the coverage rate depends on the specification and the expected wastage rate), and finally separate the ex-factory tile price from freight costs, since these are two distinct line items that should be compared independently across suppliers.

To get figures that reflect actual project needs, a quotation request should include the specification, quantity, delivery location, required delivery date, and delivery terms. With that information in hand, project owners or contractors can request a báo giá gạch Terrazzo based on the actual order, rather than relying on a generic market reference price.

Common Mistakes When Selecting Terrazzo Tiles

• Choosing the lowest price without checking anything else — specification, standard compliance, freight, and product documentation all get overlooked in the process.
• Treating dimensions as a proxy for quality — dimensions are only one of several specifications that matter.
• Not clarifying the intended use case up front — pavements, courtyards, and walkways can carry different technical requirements.
• Skipping the documentation check — a costly omission for projects that require complete material records at handover.

A Suggested Selection Process

Identify the intended use → confirm the specification → confirm technical requirements → verify standard compliance documentation → calculate quantity → request a quotation → evaluate total cost → finalize the supplier.

Frequently Asked Questions

Do all products certified to TCVN 7744:2013 meet identical requirements? No. The standard sets a common framework of requirements, but construction and specific technical parameters still vary between product lines.

Does a 400×400 mm specification automatically mean the product meets the standard? No. Dimensions are an independent specification and don’t substitute for standard compliance certification.

What documentation should a buyer request from a supplier? Product information, the specific specification, the applicable standard, and any relevant certification or test results.

How should buyers compare prices between suppliers? Only on a like-for-like basis — same specification, same technical requirements, same quantity, and same delivery terms. Otherwise the comparison doesn’t reflect the actual cost difference.

Does the quoted price include all delivered costs? Not necessarily. Freight, loading, and delivery terms need to be added to get an accurate figure for the estimate.

Conclusion

Choosing terrazzo tiles for a construction project works best in this order: intended use, specification, technical requirements, applicable standard, quality documentation, quantity, and only then cost — rather than starting with price and working backward.

TCVN 7744:2013 remains one of the key reference points for evaluating cement-bound terrazzo tiles intended for interior and exterior paving. Once the right product and quantity have been confirmed, the next reasonable step is requesting a quotation based on the project’s actual requirements.
