Sealwise WCB is waterproof sheet material that machines like MDF but absorbs zero water. We supply kitchen manufacturers and fabricators who build flood resilient kitchens. Build Back Better eligible — covered by participating insurers.
When flood water enters a home, standard MDF kitchen carcasses absorb it like a sponge. The board swells, cracks, and disintegrates — destroying doors, drawers, electrics, and everything inside. The entire kitchen goes in a skip.
This happens every time it floods. For families in flood-prone areas, it's not a question of if, but when. Kitchen companies are increasingly asked for flood resilient alternatives — and that's where WCB comes in.
Same kitchen design. Same fabrication process. Completely different outcome when water rises.
Sealwise is a sheet material manufacturer, not a kitchen company. We supply WCB to professionals who fabricate and install flood resilient kitchens.
Offer your customers a flood resilient option. WCB machines exactly like MDF — same tools, same processes, same edge details. No new equipment or training required.
We supply WCB sheet material or cut-to-size components to your specifications. You fabricate and install as normal. Your customer gets a kitchen that survives flooding.
Looking for a flood resilient kitchen? We can connect you with kitchen companies who use WCB, or supply material to your chosen manufacturer. Build Back Better (via your insurer) or government PFR grants may cover the upgrade.
Build Back Better is an insurance industry scheme run through Flood Re. Participating insurers (including Aviva, AXA, NFU Mutual, Ageas, and others) offer up to £10,000 for property flood resilience measures when repairing after a flood — on top of the standard claim. This can cover the full cost difference between standard MDF and Sealwise WCB.
Note: Government PFR grants (up to £5,000) may also be available through your local authority after specific flood events. Check with your council for eligibility.
“The MDF core of the panels had soaked up the dirty flood water and cracked, wrecking all carcasses, doors, electrical and contents. The whole kitchen needed to be stripped out and thrown in a skip. We were determined never to experience that again.

“The cabinets are surprisingly affordable, with our kitchen coming within our expected budget even with all the waterproofing changes. They were actually comparable with pre-built cabinet costs from most kitchen suppliers - so well worth it for the waterproof capabilities we could not find elsewhere.”
Customer home, Scotland. Flooded October 2023.
We supply the WCB sheet material. Your team fabricates and installs as normal.
Work with your customer to design their kitchen. Choose doors, worktops, handles, appliances. The design doesn't change — only the carcass material.
We provide WCB sheets or cut-to-size panels to your specifications. Standard thicknesses, standard sheet sizes. Delivered to your workshop.
WCB machines with standard woodworking tools. Cut it, drill it, rout it, screw it — exactly like MDF. No special training, no new equipment, no change to your process.
WCB is a closed-cell polymer board. There are no internal pathways for water to enter — not through the face, not through cut edges, not through fixings. It physically cannot absorb water at any depth or duration.
When MDF gets wet, it swells and warps. WCB doesn't. Doors stay aligned. Drawers still open. Hinges remain attached. After a flood, the kitchen still works — it just needs cleaning.
WCB machines exactly like MDF. Same tools, same fixings, same techniques. Your workshop can process it without any specialist training or equipment. The fabrication process doesn't change.
WCB is 100% recyclable and manufactured in Somerset using recycled content. When it eventually reaches end of life (decades from now), it goes back into the manufacturing process — not landfill.
WCB isn't just for flood resilience — it's the same closed-cell sheet material trusted in hospitals, veterinary facilities, dental surgeries, and cleanrooms across the UK. Paired with our W14 chemical welding system, it creates permanently sealed joints that are impossible to penetrate. Same material, same lifetime guarantee.
We'll send WCB samples with full technical data — dispatched within 24 hours. Test it in your workshop. See how it machines. Then offer your customers something MDF can't do.
