Builder's Floor Sheet for Sale
What's a Builder's Floor Sheet?
Builder’s floor sheets are purpose-made waterproof covers used in multi-storey construction.
Their job is simple but critical.
To protect the new floor or ceiling below from water damage while roofing, fitting or framing work is underway.
Unlike general tarpaulins, floor sheets are manufactured to fit your site requirements, using double-welded watertight membranes for maximum protection.

Why Builder's Floor Sheets Matter
During second-storey builds, newly laid floors and ceilings are at their most vulnerable. A sudden downpour or storm can cause water damage that leads to costly delays, rework, and frustrated clients. Builder’s floor sheets take that risk out of the equation by:
Shielding new floors from water damage
Protecting ceilings from leaks during upper-storey work
Reducing repair costs caused by construction activity
How Builder's Floor Sheets Are Used
- Sheets are supplied larger than the floor area so they can be folded and battened at the edges, forming a secure waterproof cap.
- They should only be installed once the new floor has been nailed, punched, fixed and swept, or when a roof is fully removed.
- For partially completed floors or exposed roofs, heavy duty tarpaulins are recommended instead.
Why Buy from Flynn Tarps
- We've worked with thousands of builders and know what makes a floor sheet reliable.
- Made from coated poly fabric (250gsm+) with double welded seams for strength
- Over 50-micron coating for abrasion resistance making them durable enough during construction
PRO TIP: Fabric Quality Matters
Not all floor sheets are created equal. Thinner fabrics or low-grade coatings may look cheaper upfront but fail when you need them most. Our floor sheets are manufactured for real onsite performance.
Are You Doing Enough to Protect Your Client's Biggest Asset?
Builder’s floor sheets are a smart choice, but sometimes you need more. That’s why we also hire heavy-duty PVC tarpaulins, trusted by builders, owner-builders, insurers, make-safe crews and asbestos removalists.
