About DAY Group
DAY Group Ltd is an independent, family-owned business that has been supplying construction materials and services across the south of England since 1947. The group handles over five million tonnes of construction material each year across divisions including Day Aggregates, Day Glass Recycling, Day Contracting, and Day Equestrian — as well as recycling operations processing over 1.5 million tonnes a year of aggregates from construction and demolition waste, glass, and incinerator bottom ash (IBA). With close to 200 staff across multiple depots and sites, and a large fleet of fixed and mobile plant equipment, uptime, compliance and safety are mission-critical.
“It’s made our day-to-day easy, efficient, consistent. I really recommend businesses trying to align any kind of maintenance or systems that they have — use CheckProof.”
The Challenge
Before CheckProof, DAY Group ran its maintenance, inspection and compliance processes on paper. The result was a familiar but costly set of problems: checks were difficult to verify, paper forms got lost or damaged on site, defects went under-reported, and there was no consistent audit trail across the business. As Jason Corpas Bravo, Area Depot Manager at DAY Group’s Cliffe, Newhaven, and Portslade sites, puts it — it was a system built on trust rather than evidence.
- Checks were difficult to verify — completion relied on trust rather than evidence
- Paper forms got lost, damaged, or went missing on site
- There was no consistent audit trail across the business
- Defects were under-reported and harder to track
- Coordinating compliance, risk assessments and permits across shifts and sites was time-consuming
As a multi-site business with a growing workforce, DAY Group needed a digital platform that could bring consistency and accountability to their day-to-day operations — without adding friction for frontline workers.
The Solution
DAY Group began their CheckProof rollout with a clear objective: improve planned preventive maintenance (PPM) in the production department. From there, adoption spread quickly across the business. Today, according to Jason, the platform is woven into the entire working day.
“The whole day relies on CheckProof now — wheras before we were just chasing paper around”
CheckProof is now embedded into every part of the working day at DAY Group:
Time of day
CheckProof IN USE
Start of day
Site supervisors and managers carry out site inspections via CheckProof
Morning & afternoon
Environmental daily logs recorded twice a day
Before machines start
All operators complete pre-start checks on fixed and mobile plant
During production
Compliance test weights logged and associated with specific assets
During work
Task-specific risk assessments and lockout/tagout permits raised on-app
End of day
Production numbers submitted and linked to the relevant asset
Ongoing
Defects raised in real-time as they occur during checks
Health, Safety & Compliance
CheckProof has also become a key part of DAY Group’s health and safety infrastructure. Health, safety and environment sit at the heart of the group’s values, and CheckProof now supports that commitment operationally — managing lockout/tagout (LOTO) isolation registers for both staff and contractors, permits to work, site inductions, and task-specific risk assessments built directly into check workflows. With near-miss and incident reporting already on the roadmap, DAY Group’s use of CheckProof continues to grow.
The Results

Since implementing CheckProof, DAY Group has seen measurable improvements across the business.
“There’s been a huge improvement - less downtime, more reporting of defects, more consistency with missed checks and audit trails. It’s saving the business time and money.”
Those improvements include:
- Reduced unplanned downtime through more proactive, structured maintenance
- Increased defect reporting, giving the business better visibility of plant health
- Consistent audit trails across all sites and shifts, replacing paper-based guesswork
- Fewer missed checks, with real-time monitoring replacing trust-based compliance
- Paperless production department, connecting well with younger workers
- Better cross-site alignment through a single, live dashboard
Adoption & People
One of the most telling signs of CheckProof’s success at DAY Group is how frontline workers feel about it. Despite some early internal resistance at a management level — the natural exposure that comes with greater visibility — the end users themselves have embraced it fully.
“The frontline teams love it. If you took it away from them, they’d be lost without CheckProof. Paper forms get grubby, they get lost around the plant. CheckProof is all on the app — and people never lose their phone.”
CheckProof’s permission-based structure has also helped with adoption. Users only see what they’re authorised to access, which has made the platform feel relevant and focused for everyone from operators to site supervisors. CheckProof’s permission-based structure has also helped with adoption. Users only see what they’re authorised to access, which has made the platform feel relevant and focused for everyone from operators to site supervisors. The Planning Tool, in particular, has become a core part of how the team manages training and scheduling. From a single calendar view, managers get instant visibility across all tasks, teams and shifts - seeing exactly what's been assigned, what's in progress, and what's coming up. If priorities shift or resources change, tasks can be rearranged on the fly, dragged and dropped across days or teams without losing track of anything. What used to require chasing people, checking paper rotas or making phone calls across sites is now handled from one screen. Everyone is working from the same picture, in real time.
In Summary
DAY Group’s story is one of real operational transformation — from a paper-heavy, trust-based system to a fully digital, evidence-backed operation. In Jason Corpas Bravo’s own words:
“It’s made our day-to-day easy, efficient, consistent. I really recommend businesses trying to align any kind of maintenance or systems that they have — use CheckProof.”

How to Choose the Right Work Order App for Your Industry
When something breaks on site, the fix gets most of the attention, but it’s rarely where things go wrong. What’s just as critical is everything around it: who reported it, who picked it up, what got missed between shifts, and how long it sat before anyone acted. In many operations, that whole flow is still held together by paper forms, radio calls, and memory.

Best Practices for Work Order Management
Efficient maintenance starts with clear work orders. When issues are logged quickly with the right details, photos, and priority, teams spend less time chasing information and more time fixing problems. The result is reduced downtime, smoother shift handovers, and audit-ready operations — even in low-signal or harsh environments where mobile work orders let crews flag issues before they escalate.

Predictive Maintenance vs Condition-Based Maintenance
Walk any quarry, plant, or yard and you’ll see the same thing: assets and equipment emitting tell-tale signs of its condition, long before it actually fails. Operators note “sounds off” on a pre-shift, but the note gets buried in a binder or a spreadsheet. The gap between seeing a problem and acting on it at the right time is often where maintenance strategies break down.

Downtime Reduction: How OEE, MTBF & MTTR Help You Stay Ahead
Reducing downtime starts with understanding why assets fail, how often they fail, and how teams respond. In aggregates, mining, ready-mix, trucking, and industrial plants, that insight is scattered across systems, paperwork, and the practical knowledge of operators who know which bearing runs hot or which sensor trips after rain.

Nonconformity (NC) vs. CAPA: When to Use Which?
Non-conformities can be as simple as a safety guard left open, a machine leaking oil, a batch that doesn’t meet quality standards, or a safety check that gets skipped. These are routine nonconformity issues; in other words, deviations you correct quickly to stay compliant and keep production moving. But not every issue should be closed out and forgotten.
