The Hidden Cost of Mixing and 5 Fixes Every Builder Should Know
Share
Back pain is stealing more days than rain-outs. Musculoskeletal disorders (MSDs) already sideline almost 5,000 construction workers per 100,000 in the UK each year, and back injuries are the biggest slice. The Health & Safety Executive says MSDs now cause over half of all working‐day losses in our trade. HSEHSE
Why the mixer station is ground zero
Permanent forward bend – scooping ballast, tipping 25 kg cement bags, and leaning to eyeball the water line keeps the spine flexed beyond its safe 20° for minutes at a time.
Twist-and-lift loads – rotating to dump a pan or bucket can put >1,500 N of shear on the lumbar discs.
Repetition – a small site can run 30–40 batches a day; that’s hundreds of bends.
No wonder so many brickies joke that the mixer is “the chiropractor’s best salesman”.
What “just a bad back” really costs
Average builder off with back pain loses 16 working days at £180/day labour = £2,880 direct.
Add physio bills + missed tenders and the real hit can top £5 k.
Chronic injury forces some tradespeople off the tools entirely – a personal tragedy and a skills‐gap the industry can’t afford. Raken
Five proven ways to save your spine
| # | Habit / Tool | How it helps |
|---|---|---|
| 1 | Elevate the mixer on stand, timber blocks or a scaffold trestle to waist height. | Cuts trunk flexion by 30–40 %, slashing disc pressure. |
| 2 | Clip-on water feeds (e.g., CemixFlo) so the drum fills itself. | Eliminates the “bucket‐stoop-pour” cycle entirely and keeps both hands free. |
| 3 | Long-handled shovels & bull floats with swivel knuckles. | Reduce reach and awkward wrist angles. ehrs.upenn.edu |
| 4 | Micro-break routine – 30-second hamstring/hip stretches every 30 min. | Restores spinal hydration and muscle perfusion. |
| 5 | Rotate tasks & team-lift – share bag loading or use a site hoist. | Halves cumulative load on any one worker. |
Mixing will always be part of the job, but crippling back pain doesn’t have to be. A few low-tech tweaks plus the right attachments can give you:
Fewer aches at the end of the day
Faster batch times (extra profit)
Fewer sick days and lower insurance claims
