Foundation Step Calculator

Eliminate the guesswork from stepped foundation setting out.

Foundation Step Calculator is the essential digital tool for Site Engineers, Groundworkers, Bricklayers, and Surveyors. Designed to replace manual calculations and spreadsheets, this app provides instant, accurate stepped foundation profiles that align perfectly with standard 75mm brick coursing.

Whether you are working on a simple extension or a multi-plot housing development, ensure your foundation levels are precise, compliant, and cost-effective.

KEY FEATURES:

📏 Precision Step Calculation

• Input your ground profile (Chainage & Level) and let the app calculate the optimal step locations.
• Supports Intermediate Points for complex ground profiles.
• Multiple Inputs via Level (m), Grade (%), or Ratio (1 in X).

🧱 Brickwork Compatible
• All calculated steps automatically align to the standard 75mm brick gauge.
• Eliminates "odd" courses and ensures seamless brickwork from the footing up.
• Datum Support: align your steps relative to the site Datum or adjacent plot FFL.

✅ NHBC & Building Regs Compliant

• Built-in logic automatically calculates the required concrete overlap.
• Ensures overlap is the greater of: 2x Step Height, Foundation Thickness, or 300mm (per NHBC Chapter 4.4).

📊 Visual Profile & Adjustments

• View your foundation in a real-time, interactive Visual Chart.
• See the ground line, concrete fill, and step positions instantly.
• Fine-Tune: Use the adjustment buttons to nudge the entire profile Up/Down by 75mm or remove individual steps to suit site conditions.

🚛 Concrete Volume Calculator

• Automatically calculates the total concrete volume required based on your foundation width.
• Includes calculated wastage and average depth stats.

📄 Professional PDF Reporting

• Generate detailed PDF Reports directly from your phone.
• Includes project reference, the visual chart, step coordinate tables, and volume data.
• Perfect for sending to the site team, clients, or keeping for your records.
