Blue Tarpaulin: Uses, Sizes & Why It's the UK's Most Popular Cover

The blue tarpaulin is the most recognisable cover on UK construction sites, farms, and driveways. High-visibility, highly versatile, and available in every size and weight — but not all blue tarpaulins are equal. This guide from Tarpaulins UK explains what to look for, the best uses for each weight, and which blue tarpaulin suits your job.

Why Blue?

Blue is the industry-standard colour for temporary protective covers across the UK and Europe. The bright colour makes it immediately visible for safety on sites, easy to spot for site surveys, and universally understood as a temporary weatherproof cover. Most blue tarpaulins feature a blue face with a darker navy or blue-black reverse for additional UV resistance.

Blue Tarpaulin Uses by Application

Construction & Scaffolding

The most common use for blue tarpaulins in the UK. A 250gsm–270gsm blue heavy duty tarpaulin is the industry standard for scaffold sheeting, debris containment, and site weather protection. Our heavy duty blue tarpaulins feature close-spaced eyelets (every 50–75cm) for secure scaffold tie-off.

Agricultural & Farm Use

Farmers across the UK use blue tarpaulins for bale covers, silage sheets, grain protection, and machinery covers. For agricultural use, look for a minimum 200gsm — lighter blue tarpaulin sheets will fail under the UV exposure and wind loads common on exposed farm sites.

Haulage & Transport

Blue PE tarpaulins are widely used as lorry load covers, flatbed truck sheets, and trailer covers. For transport use, a 200–270gsm blue tarpaulin with close-spaced eyelets and reinforced corners is essential. Our haulage covers are rated for motorway speeds.

Garden & Home

For covering garden furniture, outdoor storage, log piles, and seasonal equipment, a 140gsm blue tarpaulin handles the job perfectly. Lighter than site-grade covers, easier to handle, and available in smaller sizes for home use from 2m × 2m upwards.

Roofing & Emergency Weather Protection

After storm damage, a blue tarpaulin is the first line of defence for a damaged roof. For temporary roof covering, use a minimum 200gsm sheet with a large overhang and weight at all edges. Never use economy-grade covers for this application.

Choosing the Right Blue Tarpaulin Weight

Key Features to Look For in a Blue Tarpaulin

• Rust-resistant metal eyelets — avoid plastic eyelets which crack in cold weather
• Double-stitched reinforced hems — the hem is where most tarpaulins fail first
• UV-stabilised throughout (not just coated) — coating-only tarps degrade faster
• Eyelet spacing — closer spacing (50–75cm) means more secure fixing points for windy conditions
• Clearly stated GSM — any supplier not stating GSM should be treated with caution

Frequently Asked Questions

Q: Are blue tarpaulins waterproof?
A: Yes — all our blue tarpaulins are 100% waterproof with a laminated PE coating on both faces. Water will not penetrate under normal use.

Q: How long does a blue tarpaulin last outdoors?
A: Depends on GSM. A 140gsm blue tarpaulin lasts 3–5 years; a 250gsm site-grade cover lasts 7–10 years with proper use.

Q: What's the difference between a blue and green tarpaulin?
A: Colour only — both are UV-stabilised PE tarpaulin sheets with the same waterproof specification. Green blends into garden environments; blue is high-visibility for site use.
