What Our Customers Say

⭐⭐⭐⭐⭐ "Cold Storage Repair Mortar is a lifesaver for our freezer warehouse. We had a major crack in our -25°C storage area and this product allowed us to repair it without shutting down. Applied at full chill, cured in 6 hours, and it's withstood forklift traffic for 8 months. Saved us thousands in lost productivity." — Martin G., Cold Storage Manager, Grimsby

⭐⭐⭐⭐⭐ "We use this in our food processing facility and it's transformed our maintenance capability. Previously we had to warm up the entire cold store for repairs - costly and time-consuming. Now we repair cracks whilst staying at -30°C. The all-in-one kit makes application simple. Minimal disruption to operations." — Alison R., Facilities Engineer, Hull

⭐⭐⭐⭐⭐ "Applied this to our pharmaceutical cold store at -20°C and the cure time was exactly as stated - 5 hours. The compressive strength is excellent, withstands our heavy pallet traffic. The ability to repair without shutdown is invaluable for maintaining cold chain integrity. Outstanding product." — Kenneth W., Maintenance Supervisor, Scunthorpe

⭐⭐⭐⭐⭐ "Used Cold Storage Repair Mortar on our industrial freezer floor and it's performed brilliantly. Repaired multiple voids at -28°C without any warm-up. Ready for traffic in 3 hours as promised. The MMA resin technology works perfectly at extreme low temperatures. Best cold storage repair solution available." — Brenda L., Operations Director, Lincoln
