1. What is a Mortar Bed Calculator UK?

Definition: This calculator estimates the number of mortar bags needed for paving bedding based on area, depth, mix ratio, and bag yield.

Purpose: It helps construction professionals and DIYers determine how much mortar is required for UK paving projects.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M = \frac{A \times D \times R}{Y} \]

Where:

\( M \) — Mortar volume (bags)
\( A \) — Area to be paved (m²)
\( D \) — Bedding depth (mm, converted to meters in calculation)
\( R \) — Mortar ratio (unitless)
\( Y \) — Yield per bag (m³/bag)

Explanation: The area multiplied by depth gives volume, adjusted by the mix ratio, then divided by bag yield to get number of bags.

3. Importance of Mortar Calculation

Details: Proper mortar estimation ensures stable paving, prevents material shortages, and helps with cost planning.

4. Using the Calculator

Tips: Enter the area in m², bedding depth (25-50mm typical), mortar ratio (4:1 is common), and bag yield (check product specs). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical bedding depth for UK paving?
A: Usually 25-50mm, with 30-35mm being most common for residential projects.

Q2: What mortar ratio should I use?
A: A 4:1 ratio (sand:cement) is standard for most paving bedding applications.

Q3: Where do I find the yield per bag?
A: Check the product specifications - typical mortar yields about 0.017m³ per 25kg bag.

Q4: Does this include wastage?
A: No, consider adding 5-10% to the calculated amount for project contingencies.

Q5: Can I use this for other mortar applications?
A: This is specifically designed for paving bedding. Other applications may require different calculations.
