Ten ways to prepare for building in cold weather

Ryder Services is a byword for construction supplies like baulk timber, plywood, cladding, and timber headings all year round. Winter construction in the UK doesn’t come to a standstill at a flurry of snow or a cold snap, and this brings its challenges. We’re talking unpredictable weather patterns, freezing temperatures, and shorter days, impacting building materials, workers' safety, and project timelines. Here’s a blog about how you can keep your construction site running smoothly, even when the mercury plunges.

Here are ten practical ways to prepare for building in cold weather.

Thinking ahead before Jack Frost gets his claws into your plans is critical. Construction sites are more susceptible to delays and risks when the temperature drops, so schedule tasks that rely on milder conditions, like concrete pouring, for when it's warmer if possible. If all aspects of work must continue in the winter, however, create contingency plans for extreme weather and ensure timelines account for shorter working days and slower processes.

material concerns

Cold and wet weather can play havoc with building materials, like timber. It can absorb moisture and warp or split. Likewise, cement and concrete are vulnerable to frost, weakening their structural integrity if they freeze before curing, while damp can lay waste to plasterboard and insulation.

Therefore, you should try to store materials in covered, dry areas and off the ground where possible. Use insulated blankets or protective sheeting to shield materials on-site, and avoid leaving anything exposed overnight.

Cold Weather-Ready

There are, of course, construction materials specifically designed for cold weather use – like frost-resistant concrete, winter-grade sealants, and thermal insulation board, all designed to help combat the challenges of building in low temperatures.

frostbite is real

Cold weather increases the risk of hypothermia, frostbite, and other health issues, so it goes without saying that to look after your team should be your number one winter priority. Provide proper clothing, insulated gloves, thermal layers, waterproof boots, and high-visibility jackets.

Set up a heated break area where workers can take regular breaks to warm up. It’s easy to overlook staying hydrated in winter, but it is as important as in summer, plus site managers should be trained to recognise the signs of hypothermia and fatigue so action can be taken quickly.

By prioritising worker comfort, you’ll not only ensure safety but also maintain morale and productivity.

engines feel the cold

Cold weather can take its toll on construction equipment. Diesel engines can cough and splutter as they struggle to start, hydraulic fluids can thicken, and batteries can drain more quickly in low temperatures.

To keep machinery in good shape, check antifreeze levels and use winter-grade lubricants. Store smaller tools and equipment indoors overnight. Allow machinery to warm up properly before use to prevent strain on engines. Regularly inspect and maintain equipment to catch any issues early.

weather apps are where it's at

Winter weather in the UK is nothing if not unpredictable, so keeping a close eye on forecasts is key. This allows you to plan tasks accordingly, ensuring critical work isn’t disrupted by an unexpected cold snap or downpour.

If heavy snowfall or freezing temperatures are on the horizon, pause work on certain activities, like concreting or working at height, to avoid costly mistakes or accidents.

concrete has a heart

Concrete and mortar are particularly vulnerable in cold weather. They need their vitamins too. Freezing can halt the curing process, leaving you with weak and brittle results. To keep this from happening, you can use frost-resistant additives in your concrete mix. Keep materials warm before mixing. Avoid pouring concrete in freezing temperatures where possible, and insulate freshly-laid concrete with blankets or heating methods to maintain curing temperatures.

Light Up, light up

The days are shorter in winter, so you’ll need additional lighting to keep the site safe and productive, so that workers can see hazards clearly, machinery and vehicles can operate safely, and the overall site remains secure and visible.

Invest in high-quality LED floodlights, as they’re energy-efficient and provide excellent visibility. Don’t forget to check that all lighting systems are regularly maintained and suitable for outdoor use in winter conditions.

Keep Work Areas Clear

Snow, ice, and mud can quickly turn a construction site into a hazardous heap. A tidy site is a happy, productive site. Slips, trips, and falls are a major risk, so prioritise keeping walkways and work areas clear.

Regularly grit pathways to prevent ice build-up, and clear snow promptly to avoid it turning to ice. Use temporary, non-slip matting or boards in high-traffic areas, and ensure drainage systems are functioning to avoid puddles and standing water freezing over.

a chatty ship is a happy ship

Good communication and training are key to running a happy ship in winter. Make sure everyone on site understands the additional risks that cold weather brings and what steps to take to minimise them. Training site workers and managers to recognise cold-related health risks, operate machinery safely in winter, and protect materials will ensure everyone is equipped to tackle the season head-on are all good ideas.
