Pre-Planned Maintenance
(PPM) Services
Unexpected drainage failures bring businesses to a sudden standstill. For commercial properties, restaurants, and high-footfall sites, waiting for a drain to block means lost revenue, health code violations, and emergency callout expenses.
At BLOKD Drainage, we deliver proactive Pre-Planned Maintenance (PPM) contracts across Kent, Essex, London and the South East. Tailored to your specific building layout and operational demands, our scheduled maintenance programmes prevent blockages before they happen—keeping your pipework clean and fully functional year-round.
Whether you manage a busy commercial kitchen, a retail complex, an educational facility, or residential housing blocks, we keep your drainage network clear—backed by transparent pricing and minimal operational disruption.
Signs Your Property Needs a Scheduled Maintenance Plan
Waiting for an emergency is the most expensive way to manage commercial drainage. Your facility needs a scheduled maintenance plan if you notice these warning signs:
Frequent Emergency Callouts
Repeat blockages occurring every few months in heavy-use lines like commercial kitchens or main stacks.
Recurring Foul Odours
Sewage or stagnant grease smells escaping into customer areas, dining spaces, or office corridors.
Slow-Draining Heavy-Use Fixtures
Sinks, gulley grates, or washroom toilets consistently draining slowly during peak operational hours.
High Commercial Footfall
Properties operating commercial kitchens, shared amenities, or public restrooms that process high volumes of fat, paper, and waste daily.
What Our PPM Schedules Cover
Our customisable maintenance plans are designed around your site’s specific drainage infrastructure to target high-risk areas:
High-pressure water jetting of main underground lines and stack pipes to remove fat and scale buildup
Quarterly or bi-annual clearing and de-greasing of commercial kitchen waste pipes and grease traps
Clearing, de-silting, and vacuum emptying of outdoor gullies, catchpits, and petrol interceptors
Routine HD CCTV structural checks to spot small cracks or pipe sags before they cause a collapse
Descaling internal soil stacks and urinal pipework to maintain full bore capacity
Pre-winter drainage inspections to clear fallen leaves, silt, and storm drain debris
The Risks of Operating Without a Maintenance Plan
Relying purely on reactive emergency repairs introduces major operational and financial hazards to your business:
Costly Business Downtime
Sudden toilet backups or flooded kitchens can force temporary closures, leading to lost trade and damaged business reputation.
Environmental Health Violations
Overflowing commercial drains or compromised grease traps risk severe health inspection fines and potential operational shutdowns.
Premature Infrastructure Replacement
Unmaintained pipes suffer from accelerated scale buildup, internal corrosion, and structural stress—shortening their operational lifespan significantly.
