Rainfall Preparedness for Buildings in Qatar:
December Safety Advisory
By Caltiq Trading, Contracting & Maintenance W.L.L.
In Qatar, rainfall is limited but often sudden and intense, particularly during December, which marks the start of the peak rainy season. Without proper preparation, rain can cause electrical hazards, flooding, shaft leakages, and rooftop water accumulation, leading to serious safety and operational issues.
At Caltiq Trading, Contracting & Maintenance ., we emphasize preventive maintenance and early inspections to safeguard people, properties, and critical building systems.
At Caltiq, our engineering teams operate across Qatar, ensuring that villas, apartments, and commercial buildings enjoy safe, reliable, and efficient hot-water performance.
When Is Rain Expected in Qatar?
- Peak rainy period: December to February
- Sudden heavy showers and occasional thunderstorms
- Short rainfall duration but high impact
- Basements, shafts, rooftops, and electrical rooms are most vulnerable
December is the ideal time to conduct safety inspections and cleaning works.
1. Electrical Safety Precautions (Critical)
Rainwater ingress into electrical systems is extremely dangerous.
Key Safety Guidelines:
- Inspect rooftop and outdoor electrical panels, isolators, and DBs.
- Ensure proper IP-rated enclosures and sealed cable entries.
- Test ELCB / RCCB / RCD functionality.
- Avoid exposed wiring or temporary connections outdoors.
- Immediately isolate power if moisture or corrosion is observed.
2. Drainage, Flooding & Plumbing Safety
Poor drainage is the leading cause of rain-related damage.
Preventive Measures:
- Clean roof drains, rainwater outlets, and downpipes.
- Clear manholes, floor traps, and inspection chambers.
- Ensure basement sump pumps and float switches are operational.
- Check Non-Return Valves (NRVs) to prevent sewage backflow.
- Verify discharge lines are free from blockages.
3. Shaft Inspection & Cleaning (Very Important)
Service shafts are often overlooked but are a major source of leakage during rain.
Safety & Maintenance Guidelines:
- Inspect MEP shafts (electrical, plumbing, HVAC) for water seepage.
- Remove debris, loose materials, and construction waste from shafts.
- Seal open penetrations around pipes, cables, and ducts.
- Check vertical rainwater pipes inside shafts for leakage or cracks.
- Ensure shaft access doors are properly closed and sealed.
Unclean or unsealed shafts can allow rainwater to travel across multiple floors.
4. Rooftop Cleaning & Housekeeping (Essential)
Dirty rooftops can cause severe water ponding and leakage.
Rooftop Safety Checklist:
- Remove dust, sand, leaves, and debris from rooftops.
- Ensure all roof drains and scuppers are clean and open.
- Clear AC condensate drain outlets.
- Remove unused materials, loose cables, and scrap items.
- Ensure proper slope toward drainage points.
Regular rooftop cleaning significantly reduces water accumulation during rain.
5. Basement & Low-Level Area Protection
Basements face the highest flooding risk.
Key Measures:
- Inspect waterproofing in basement walls and floors.
- Ensure electrical rooms are protected from water ingress.
- Test sump pump auto and manual operation.
- Avoid storing materials directly on basement floors.
- Keep emergency access routes clear.
6. Roofing, Waterproofing & Building Envelope
Minor defects can lead to major damage.
Inspection Points:
- Check waterproofing membranes for cracks or blisters.
- Inspect sealant joints at skylights, AC penetrations, and parapets.
- Secure loose rooftop equipment.
- Inspect balconies and terraces for proper drainage slope.
7. HVAC & Mechanical Equipment Safety
Rain can affect performance and equipment life.
Recommended Actions:
- Ensure outdoor units are elevated and drained properly.
- Inspect insulation on refrigerant lines.
- Clear condensate drain lines.
- Check package units and AHUs for water ingress.
8. General Workplace & Occupant Safety
Rain increases slip and fall risks.
General Safety Measures:
- Place anti-slip mats at entrances.
- Display warning signage in wet areas.
- Ensure emergency lighting and exit signage are functional.
- Restrict access to flooded or unsafe areas.
9. Fire Alarm & ELV System Protection
Low-voltage systems are also vulnerable to rain.
Key Checks:
- Inspect fire alarm devices exposed to moisture.
- Ensure outdoor detectors and sounders are weather-rated.
- Check CCTV cameras and ELV junction boxes for water ingress.
- Seal ELV conduits and trunking entries
10. Penetration Areas & Façade Glass Wall Safety (Critical During Rain)
Penetration points and façade glass systems are among the most vulnerable areas during December rainfall in Qatar. Even small gaps can allow rainwater to travel into ceilings, shafts, and electrical zones.
Penetration Area Safety Guidelines
Penetrations include areas where pipes, cables, ducts, and supports pass through slabs, walls, or roofs.
Key Preventive Measures:
- Inspect all roof and wall penetrations for cracks, gaps, or failed sealants.
- Ensure proper sealing around MEP penetrations using approved waterproof sealants.
- Check pipe sleeves and ensure correct flashing is in place.
- Seal unused or abandoned penetration openings.
- Inspect penetrations inside MEP shafts to prevent vertical water migration.
- Verify fire-stopping and waterproofing are intact and undamaged.
Unsealed penetrations can allow rainwater to spread across multiple floors.
11. Façade Glass, Curtain Wall & External Cladding Safety
Façade systems are constantly exposed to wind-driven rain.
Safety & Inspection Checklist:
- Inspect glass-to-frame sealant joints for cracks or aging.
- Check silicone sealants at façade joints and expansion joints.
- Inspect curtain wall drainage channels and weep holes.
- Check glass panels for movement, gaps, or loose fixings.
- Inspect interface areas between façade and slab edges.
- Check for water stains inside, indicating hidden leakage paths.
Early detection prevents internal ceiling damage, mold formation, and electrical risks.
12. Preventive Maintenance & AMC Advantage
Proactive maintenance minimizes emergency breakdowns.
