A tablet doesn’t like condensation and a phone doesn’t like being handled with wet or muddy fingers, so plenty of what gets recorded on a wet site day still gets written down by hand — a crack pattern, a damp-meter reading grid, a rough floor layout before it goes into a proper plan. The trouble is what an ordinary notepad does on exactly the kind of day that makes taking notes by hand necessary in the first place: driving rain on a roof inspection, a dripping loft hatch, condensation running down the inside of a single-glazed window while it’s being measured. Standard paper turns to pulp within a page or two, and whatever was written on it goes with it.
A genuinely waterproof notebook solves that one problem — treated or synthetic paper that can still be written on while it’s wet, not just a cover that shrugs off a splash while the pages underneath stay ordinary. It doesn’t replace a dictaphone for a running verbal commentary through a loft; it’s the thing that’s still legible after it’s been rained on or handled with a wet glove.
What follows is built from manufacturers’ own paper-technology claims and cross-checked published feedback, including one notebook worth buying for its format but which doesn’t actually belong in the waterproof category at all — and is sold alongside these seven anyway.
The one I’d buy
Rite in the Rain No. 946 Top-Spiral Notebook
The same treated All-Weather paper as every Rite in the Rain product in this guide, in the format that actually suits a full page of site notes: 4×6 inches, top-bound on a spiral so it flips flat and one-handed while the other hand’s holding a torch or a damp meter probe. At around £8 it’s also the cheapest notebook here, which makes it the default buy rather than a compromise.
Typically £7–£9
Check price on AmazonHow I judge a waterproof notebook
Genuinely waterproof paper, not just a wipeable cover. Treated or synthetic paper that can be written on while wet is a different product from a tough cover wrapped around ordinary paper — check the paper technology, not just the word “waterproof” on the listing.
What actually writes on it. Coated and synthetic papers can resist a standard ballpoint as well as they resist rain; most manufacturers here recommend a pencil or a pressurised all-weather pen instead.
Format matched to the job. A pocket pad for a couple of figures, a full spiral or A5 page for a sketch or a reading grid — the wrong size either gets left in the van or runs out of room.
Binding that survives a pocket. Spiral, stapled and casebound all behave differently in a jacket pocket or a tool bag over a full day; a rigid hardcover that digs in on a ladder gets left behind.
Enough pages without becoming another thing to carry. A 48-page pad runs out mid-survey; a 160-page casebound is bulk that only earns its place if the notes need to last months, not one visit.

The picks in detail
Rite in the Rain No. 946 Top-Spiral Notebook
Best overall — flips one-handed like a proper site pad
The 946 is the same treated All-Weather paper as every Rite in the Rain product here, in the format that suits a full page of site notes rather than a two-line pocket jotting: 4×6 inches, top-bound on a spiral so it flips flat and one-handed while the other hand’s holding a torch or a damp meter probe. The Universal ruling mixes ruled lines with a faint grid, which covers a written note and a quick sketch on the same page without switching notebooks. At around £8 it’s also the cheapest item in this whole guide, which makes the case for it as the default buy rather than a compromise.
For
- Full-page size, flips one-handed
- Universal ruling covers notes and sketches
- Cheapest notebook in this guide
Against
- Ordinary biro can skip on the coated paper
- Spiral binding adds a little bulk over stapled
Typically £7–£9
Check price on AmazonRite in the Rain Universal Fabrikoid No. 970F-M
The premium pick — one casebound record for the whole job
The 970F-M swaps the spiral for a sewn, casebound spine under a coated-fabric hardcover — the construction of a proper site diary rather than a disposable pad. 160 pages of the same waterproof paper means one book can outlast several jobs before it needs replacing, useful if a return visit or a dispute months later needs the original notes in one place. It’s the most expensive notebook here, and the current listing’s stock has been thin, so check availability before relying on it as the only book in the van.
For
- Sewn casebound spine, built to last
- 160 pages, most capacity here
- One book covers months of work
Against
- Most expensive notebook in this guide
- Stock has run low on the current listing
Typically £23–£27
Check price on AmazonModestone A5 Side-Spiral Waterproof Notebook
Best full-page format — genuine A5 for a proper sketch
Modestone’s paper isn’t a coated wood-pulp sheet like the Rite in the Rain range — it’s stone paper, made mostly from calcium carbonate rather than wood fibre — and it comes in a genuine A5 page with a 7×7 mm grid, bigger than anything else in this guide. That’s the size worth having when a page needs a full room sketch or an elevation with dimensions on it, not a couple of lines. Pen compatibility is the one claim I can’t independently confirm from the manufacturer — published feedback suggests a ballpoint copes fine and a fountain pen doesn’t, so treat gel or fountain ink with caution.
For
- Genuine A5 page, biggest here
- Stone paper, a different technology to coated wood-pulp
- NATO stock number, genuine trade/military origin
Against
- Pen compatibility not manufacturer-confirmed
- Less well known a brand than Rite in the Rain
Typically £13–£15
Check price on AmazonRite in the Rain No. 964 Universal Notebook, Field-Flex Cover
A cover that bends in a pocket instead of cracking
The 964 carries the same waterproof paper and Universal ruling as the rest of the range, but in a soft, flexible cover rather than the rigid Polydura or fabric hardcover used elsewhere in this list — it bends with a jacket pocket instead of digging in on a ladder or under a tool belt. At 120 pages it sits between the pocket pad and the full casebound book on capacity, which makes it a reasonable single choice if only one notebook is going in the bag for the day.
For
- Flexible cover, comfortable in a pocket
- 120 pages, a middle ground on capacity
- Same All-Weather paper as the rest of the range
Against
- No rigid back to write against without support
- Costs more than the plain 946 for less page count
Typically £10–£12
Check price on AmazonExacompta Chartwell Survey Book 2056
The classic UK site book — water-resistant, not waterproof
This is the notebook that’s been in a UK site engineer’s top pocket for decades, with the traditional graph ruling and twin red centre lines that make it easy to mark a datum or a chainage without a straightedge. It needs saying plainly, though: the manufacturer’s own claim is “excellent strength when wet”, not waterproof, and the paper is a traditional wet-strength stock rather than the synthetic or coated paper used by every other product here. It’ll survive a damp hand and a few raindrops without disintegrating, and takes an ordinary pen without complaint, but it won’t take being properly rained on the way the Rite in the Rain or Modestone books will — buy it for the format and the familiarity, not genuine waterproofing.
For
- Classic survey ruling with red centre lines
- Ordinary pen or pencil works fine
- 160 pages, casebound
Against
- Water-resistant, not genuinely waterproof
- Won’t survive being written on properly wet
Typically £14–£16
Check price on AmazonRite in the Rain All-Weather Notebook No. 135
Cheapest single pad — a pocket spare, not a primary notebook
The 135 is the smallest and simplest thing here: a stapled 3×5 inch pad, the same All-Weather paper as the rest of the range, no spiral or hardcover to add bulk. It’s too small to write up a full set of survey notes in, but it’s the one that fits in a shirt pocket without being noticed, which earns it a place as a backup carried alongside a bigger notebook rather than instead of one. Rite in the Rain’s own listing recommends a pencil or one of its pressurised all-weather pens over an ordinary biro, which applies to every notebook in this range, not just this one.
For
- Smallest, most pocketable option
- Same waterproof paper as the rest of the range
- Cheap enough to carry as a spare
Against
- Too small for a full set of site notes
- Stapled binding, not repairable if it fails
Typically £8–£10
Check price on AmazonField Notes Expedition Edition (3-Pack)
Budget backup — genuinely waterproof, thin at 48 pages
Field Notes built the Expedition Edition around Yupo synthetic paper — a polypropylene sheet rather than a treated wood-pulp one — and it’s a genuine waterproof claim, not a marketing stretch: confirmed across the brand’s own specification and independent stationery reviewers. Sold as a pack of three 48-page pocket notebooks, it’s one of the cheapest ways into a properly waterproof notebook per unit, though 48 pages doesn’t go far on a full survey. Pencil, ballpoint or a fine permanent marker all work; gel and fountain pen ink sit on the surface rather than soaking in and will smear.
For
- Genuinely waterproof Yupo synthetic paper
- Three notebooks in one purchase
- Cheapest per notebook in this guide
Against
- Only 48 pages per notebook
- Gel and fountain pen ink smears on the surface
Typically £19–£21 for the pack of three
Check price on AmazonWhat actually matters — and what doesn’t
Genuinely waterproof paper, not a wipeable cover. Coated, synthetic or stone paper can be written on while it’s actually wet. A tough or wipeable cover round ordinary paper only protects the block while it’s closed — the Exacompta Chartwell here is the honest example of that distinction, worth checking before assuming the word “waterproof” on a listing means what it says.
Pencil or a pressurised pen beats an ordinary biro. On coated or synthetic paper a standard ballpoint can skate across the surface or fail to lay ink down at all, especially once the page is properly wet — every manufacturer here using treated paper says as much on its own listing.
Format matched to the job, not the widest page available. A pocket pad that never gets carried because it’s inconvenient protects nothing. Buy the size that actually fits the pocket or bag it’ll live in day to day.
Casebound versus spiral is about longevity, not toughness. A sewn hardcover earns its price when it’s the one place a job’s notes live for months; a stapled or spiral pad is disposable, and that’s fine if that’s what it’s bought for.
What the listings push that doesn’t matter: tactical branding and cover colour. Olive drab, a “tactical” name and black-over-green options sit on the same paper technology as the plain version and change nothing about what the notebook can survive.
Questions I get asked
Can I write on a waterproof notebook with a normal pen?
Sometimes, but don’t rely on it. The coated and synthetic papers used across this guide are designed to repel water, which means an ordinary ballpoint can skate across the surface instead of soaking in, especially once the page is actually wet. Every Rite in the Rain listing recommends a pencil or one of the brand’s own pressurised all-weather pens; the same caution applies to Field Notes’ Yupo paper and Modestone’s stone paper. A regular biro works fine on the Exacompta Chartwell, because that one uses traditional paper rather than a waterproof coating.
What’s the actual difference between waterproof and water-resistant?
Waterproof paper — coated, synthetic or stone paper — can be written on while it’s actually wet and dries without the ink running or the page disintegrating. Water-resistant covers just protect a normal paper block from splashes while it’s closed; open the cover in the rain and the pages inside behave like any other notepad. The Exacompta Chartwell in this guide is the water-resistant case in point: a tough cover round paper that’s stronger when damp than standard stock, but not paper that’s meant to be written on while wet.
Which format should I buy — pocket pad or full page?
A pocket stapled pad like the Rite in the Rain 135 is for short notes and quick figures, and it’s small enough to actually be carried every day, which matters more than page size if a bigger notebook ends up left in the van instead. A full A5 or 4×6 spiral notebook — the 946 or the Modestone — earns its size back the first time a sketch, a damp-meter reading grid or a room layout needs a proper page rather than a margin.
Do I need a specific brand, or will any “waterproof” notebook do?
Check what the paper technology actually is before buying, not just the word “waterproof” on the listing. Rite in the Rain’s coated paper, Field Notes’ Yupo synthetic sheet and Modestone’s stone paper are all genuinely writable while wet; a notebook that only claims a “weatherproof” or “water-resistant” cover, like the Exacompta Chartwell in this guide, is a different and more limited product even when it turns up in the same search results.
A notebook that survives the weather is a small thing next to the finding it records — a damp reading, a crack width, a missing vent. If a property in Sussex, Kent or Surrey needs a proper look, a building survey or a HomeBuyer Survey covers that; get in touch, or browse the rest of the field-kit guides, including dictaphones for the notes that get spoken instead of written and label printers for what happens to a sample once it’s bagged.
