Have you ever wondered if the truck driver delivered the exact amount of sand you ordered? Many construction site managers don't know how to verify this if they don’t have Kata available, usually referred to Kanta reading at loading and delivery time.
This guide shows you a simple method that any site supervisor can use in 15 minutes to verify sand deliveries—whether it's Medium Sand, Plaster Sand, or M-Sand.
Know Your Sand Types
Medium Sand: Fine to medium grains (0.25-0.5mm), used in plaster work and general construction
Plaster Sand: Very fine grains (<0.25mm), ideal for plaster, mortar, and finishing work
M-Sand (Manufactured Sand): Crushed stone sand, stronger and more angular, used in concrete, masonry, and quality mixes
Why Verification Matters
Sand is sold by volume (cubic feet or cubic meters) or by weight (tonnes). If you order 100 CFT and receive 80 CFT, you won't realize the shortage until you're already mixing mortar (cement, sand & water mixture) or concrete. Then work stops. You call your supplier. You wait for a re-delivery. Your project timeline slips. Your labor costs increase. One simple verification check prevents all of this. It takes 10-15 minutes and requires no special tools—just measuring tape.
The Hyva Truck Arrives: Take Three Measurements
When the truck dumps the pile, you need to measure three things:
Length: Measure from the front of the pile to the back. If the pile tapers at one end, measure at two points (front and back) and average them.
Width: Measure side to side. Measure at one or two points—most piles are rectangular.
Height: Measure at three points—left, center, and right. Average these three heights. This accounts for piles that are flatter in the middle.
It is also measured through sticks or rods when theh materials are delivered through non-Hyva trucks but key to measure the volume when materials are delivered and avoid any quantity shortfall.
Calculate Volume: From Feet to Tonnes
Let's say you measure a pile and get: Length = 9.24 feet, Width = 5.25 feet, Height = 6 feet (average). Here's how to convert this to cubic feet and then to tonnes:
Step | Formula | Result |
|---|---|---|
1. Get CFT | L × W × H | 9.24 × 5.25 × 6 = 291 CFT |
2. Convert to Tonnes | CFT × density factor | See chart below |
Quick Conversion: CFT to Tonnes by Sand Type
Sand Type | CFT to Tonnes Factor | Example: 291 CFT = ? |
|---|---|---|
Medium Sand | 1 tonnes ~25 cft | 11.64 cft |
Plaster Sand | 1 tonnes ~25 cft | 11.64 cft |
What to Do With Your Results
Now you have your cubic feet and tonnes. Compare both numbers to your purchase order.
If it's within 5% of what you ordered, accept it. Small variations are normal due to measurement of rounding.
If it's more than 5% short, stop. Contact ConstroMat before the truck leaves. Request an adjustment or re-delivery.
If you have extra, document it. You may get credit or a discount on your next order.
