The company

Kernbohr-Expert is a Dresden company for core drilling and wall openings in concrete, reinforced concrete and masonry, with diameters from 14 to 500 mm and depths up to 2 m. Before a job, the question is usually the price – that is where the modernisation starts.

The price calculator

Under “Richtpreis in 30 Sekunden” (indicative price in 30 seconds) the visitor enters:

• Material: concrete/reinforced concrete or masonry
• Diameter in mm, depth or wall thickness up to 200 cm and number of holes
• Drilling direction: standard, overhead or inclined (with surcharges)
• Time: weekday, night (23:00–06:00) or weekend/holiday (with surcharges)
• Extras: water vacuum and scaffolding, each per day

The result is a non-binding gross indicative price with a visible calculation. From there the visitor can enquire directly by WhatsApp or email, or download a PDF quote. The PDF is created in the browser; no data is transmitted. The basis is the 2026 price list; reinforcing steel from 1.5 cm and waiting time are charged separately.

The Kerni assistant

At the end of the page, “Kerni fragen” (ask Kerni) offers three direct routes: call, write by WhatsApp or jump to the quote in the calculator.

Structure for search engines and AI assistants

• FAQ section with 6 questions including FAQPage markup, plus a HowTo guide with HowTo markup
• A direct answer in the opening paragraph (54 words) and 6 question-based headings
• llms.txt, an llms variant file and /.well-known/ai.txt
• The robots.txt allows all 10 checked AI crawlers; overall the test detects 19 types of structured data
