Frequently Asked Questions –
Construction Calculators
How do you calculate the number of slabs needed for a patio?
To calculate the number of slabs required:
-
Measure the total area (length × width) in m² or ft²
-
Divide by the area of one slab (including joint spacing)
-
Our Slab & Paver Calculator does this instantly for you!
What is the best mix for laying slabs?
The recommended slab mortar mix is 4:1 (4 parts sharp sand to 1 part cement). For heavier loads, use 3:1 for extra strength.
How much cement, sand, and MOT do I need for a patio base?
The Patio Base Calculator estimates the exact amount of MOT, sharp sand, and cement needed for your slab foundation based on your chosen mix ratio and depth.
What is the mix ratio for concrete?
Common concrete mix ratios include:
-
1:2:4 (Cement:Sand:Gravel) – Standard mix for general concrete
-
1:3:6 – Suitable for foundations and non-load-bearing structures
-
4:1 Mortar Mix – Ideal for laying patio slabs
