PRACTICAL COUNCILS FOR PRODUCERS AND STAKEHOLDERS

How to prepare a kitchen corpus for a stone worktop?

When installing a stone worktop it is not enough just to precisely work the stone – the foundation of success is a well prepared corpus that can handle the weight and specifics of this material. Here is an overview of the most important rules that the carpenter should think about already in the production of the kitchen.

1. Solid and stable construction is the basis

Stone slabs are significantly heavier than laminate or solid timber. 
The body shall be designed to:

  • is sufficiently firm and stable,
  • did not bend,
  • did not work (e.g. due to moisture).


Recommendation:

Use high quality DTD or MDF plates with a thickness of min. 18 mm, fixed joints and no compromises in the construction.

2. Without upper reinforcement partitions – only support strips

If there’s a stone plate on the lockers, DO NOT USE Full top plates to close the corpus.

Instead, use only the mounting strips on the front and back (width approx. 60-100 mm) which serve as support and facilitate handling during installation.

Why?

The stone must be placed directly on the structure, not on the top top plate, and could cause tension, dilation and subsequent damage to the stone.

3. Plane security

The upper edge of the corpus must be Absolutely equal and in one plane.
The installation of stone does not compensate for inequalities, as is common with the laminate.

  • Recommended deviation: max. 1znaczon2 mm in length 2 metres.
  • Irregularities can lead to the crack of the stone during use.


✔✔
Before installation we always recommend to do a flatness control measurement.

4. Support in the areas of appliances and cut-outs

There shall be no empty space under the stoneboard without support.

For hobs, sinks or dishwashers, add mounting strips (panes) to provide support.

Beware of dishwashers – produce moisture. Protective foil and correct ventilation are necessary.

5. Preparation of cuttings and openings

All cuts (for sink, hob, batteries, etc.) are implemented in stoneware production Not in the carpenter’s workshop.

But what you can prepare:

  • Accesses for water and electricity distribution
  • Centred cut-outs in the back walls
  • Battery passes, drivers


✔✔
Always provide precise technical drawings The communication between the carpenter and the stonemason is crucial.

6. Arrange the order of installation in advance

Ideal assembly order:

  1. corpus installation services
  2. Focusing of the stone
  3. Production and processing
  4. Installation of stone slabs
  5. Final fitting of appliances

7. Cooperation and consultation are essential

Each project is specific. recommended:

  • Consulting technical details already at the design stage
  • Prepare accurate drawings and 3D visualization
  • Collaborate in targeting and assembly


Regular communication between carpenter, architect and stonemaker prevents unnecessary errors, time losses and complaints.
