What Is a Tarpaulin?
A tarpaulin (often shortened to “tarp”) is a large sheet of strong, flexible, water-resistant or waterproof material designed to provide protection from weather, debris, dust, and moisture.
Modern tarpaulins are typically made from polyethylene (PE), PVC, canvas, or mesh, and are reinforced with hems and eyelets for secure fastening.
Types of Tarpaulins
Choosing the correct tarp starts with understanding the different types available.
1. Polyethylene (PE) Tarpaulins
Polyethylene tarps are lightweight, waterproof, and highly versatile. They are available in various thickness levels (measured in GSM).
They are ideal for: Garden use, DIY projects, Temporary covers, General household protection.
Best for: Everyday, short- to medium-term use.
2. Heavy-Duty PE Tarpaulins
Heavy-duty tarps are thicker and more durable, designed for tougher environments.
They are commonly used for: Construction sites, Industrial storage, Long-term outdoor covering, Agricultural protection
These tarps often feature reinforced corners and stronger eyelets for improved durability.
Best for: Long-term outdoor exposure and demanding environments.
3. PVC Tarpaulins
PVC tarps are covers known for their strength, durability, and resistance to harsh weather conditions.
They are: Fully waterproof, Highly tear-resistant, Resistant to oil and chemicals, Suitable for transport and industrial use
Best for: Haulage, heavy industry, and long-term weather exposure.
4. Canvas Tarpaulins
Canvas tarps are breathable and traditionally used where condensation needs to be avoided. Unlike PE tarps, canvas is water-resistant rather than fully waterproof unless treated.
They are ideal for: Covering machinery, Wood storage, Equipment protection
Best for: Situations where airflow is important.
5. Mesh Tarpaulins
Mesh tarps allow airflow while providing shade and debris control.
Common uses include: Scaffolding sheeting, Trailer covers, Garden shading, Skip covers
Best for: Wind reduction and ventilation.
Understanding GSM (Grams per Square Metre)
GSM measures the weight and thickness of a tarpaulin material.
50 GSM (S-Grade): Lightweight, temporary use
90-100 GSM (M-Grade): Medium-duty, general purpose
200+ GSM (L-Grade or XL-Grade): Heavy-duty, long-term outdoor use
The higher the GSM, the thicker and more durable the tarp. If you’re unsure, choosing a slightly heavier GSM often improves lifespan and value for money.
Common Uses for Tarpaulins
Tarps are used across multiple industries and applications.

How to Choose the Right Tarpaulin
When selecting a tarp, consider:
1. Weather Exposure
Will it face strong wind, heavy rain, or snow? Choose heavy-duty for harsher conditions.
2. Duration of Use
Short-term projects can use lighter tarps. Long-term exposure requires higher GSM.
3. Size
Always allow extra material for tying down and securing.
4. Waterproof vs Breathable
Need full waterproofing? Choose PE or PVC.
Need airflow? Choose canvas or mesh.
5. Fixing & Accessories
Use bungee cords, rope, or tarp clips to prevent tearing and distribute tension evenly.
How to Make Your Tarpaulin Last Longer
Secure it tightly to prevent wind flapping
Avoid sharp edges underneath
Clean before storage
Let it dry fully before folding
Store in a cool, dry place
Proper care significantly extends lifespan and protects your investment.
