Extraction To Delivery

Delivering you the best-of-its-quality products is made possible because of our cutting-edge technology combined with the unparalleled skills of our team. We are working with quarries in areas with the largest reserve of high-quality white marble in Vietnam.

Our on site team will take care of quality control service in high standards including: blocks selection, pre-production meetings, inspections, on-time deliveries and logistic assistance in case needed. We are a one stop shop; we quarry, process, and trade these precious stones assuring you quality every step of the way.

Step 1 – Extraction of Stone Blocks from Quarry

Marble quarries are places so unbelievable and striking; they almost feel like they are big theaters or sets. The principle objective of blasting is to develop cracks in the rock so as to dislodge it from the surrounding rock without causing damage to it or to the remaining rock. Drilling is generally carried out by jackhammer but now-a-days compressed air operated hydraulic machines are coming into use. Stone Blocks are further sent for processing.

Step 2 – Process Before Block Cutting

After the blocks are extracted from the quarry, they’ll go through further processing to match their intended purpose. From the quarry and until they are loaded onto containers ready for shipment, marble slabs go through different transformation phases.
Once each block is extracted from the quarry, these are classified based on certain quality criteria, such as:
  • Block Size, Tones
  • Amount of streaks: the lower the amount of streaks, the higher quality and better classification.
  • Cleanliness: clean materials are those with no stains and cracks.
Due to their large dimensions and heavy weight, the blocks need to be moved and handled with cranes and specific machines, both during loading/ unloading and during processing.

Step 3 – Block Cutting

Marble slabs for construction or sculpture are cut using diamond wires or a gang saw, which uses multiple diamond-tipped blades to slice a marble block into more manageable slabs. Marble is cut using multiwire or block cutters. Depending on their dimensions, blocks may be cut using different methods, i.e., large blocks will be processed in the multi wire cutter, while smaller, irregular blocks will be cut using block cutters. The aim is to make the most of the block’s measurements by reducing any waste as much as possible.

Multiwire cutters will produce slabs. On the other hand, block cutters will produce strips that will be subsequently processed by the mitre saw or cutter in order to create tiles.

Step 4 – Fabrication & Polishing of Stone Slabs

Slabs are taken to the production line for further processing. As a first step, the material is strengthened by attaching a mesh for further resistance.

We are bringing your design ideas to life. We stock a comprehensive range of pre-cut, raw stone slabs from which we can fabricate anything from pool surrounds, staircases to worktops & hearths.

Our professional craftsmen will beautify your home with great pride and care – using traditional, time-tested quality fabrication and installation. Our professional design staff will guide you every step of the way – with knowledge and expertise through the selection and specification process.

Step 5 – Finishing of Stone Slabs

Stones are finished by repeated application of abrasive treatments. This technique produces a shiny surface, with almost zero porosity, while improving resistance. Polished finish highlights the color and properties of the natural stone.

It is commonly used as interior wall and floor dressing, as well as bench tops and in kitchen countertops. It is not recommended for outdoor paving, since it reduces slip resistance.

Step 6 – Quality Check and Ready to use slabs

We ensure size and specification inspection which includes the checking of the length, width, and thickness within the approval tolerance; the diagonal length, angle control etc. Material appearance inspection includes Color, Texture, Spots, Color Lines, uniform crystal / grain structure etc. Surface Finishing Inspection includes Polished, Honed, Flamed, Bush Hammered, Tumbled, Natural Cleft, Bevel Edge etc.Other Defects Checking includes Scratches, Cracks, Broken Edges, Chip Edges, Pin holes, swirl marks, Repairs etc. Other production process includes Degree of polish, Flatness and Angle of straight edges.
Once the corresponding finish has been applied, the slabs will be ready for display or will go directly to packaging ready for shipment. If the marble slabs are being shipped abroad, a series of wooden bundles will be prepared in order to introduce them into containers. While if your slabs are being shipped within India, these are transported using iron a frames to hold them in place.

Step 7 – Stone Installation for Royal look to Interiors

Marble made a modern twist in the world of interior design; however, it is necessary to use it in small doses, accents and pieces. If you want to follow the trends and use of marble in the interior, look for creative ways to incorporate marble into your interior. Marble slabs in the interior give the impression of wealth and glamour. Mostly are used on large areas in the spacious and luxurious interiors. It is strong, powerful and will last a lifetime.
