Floods can significantly disrupt construction sites, leading to project hold-ups. A rapid and systematic approach is essential to resume work promptly, addressing issues like water-filled footings and site drying.
Powering your site
For flood-affected or challenging sites, our selection of petrol and diesel generators ensures continuous power supply. These robust generators keep your projects running during tough times.
Clearing the Water: Choosing the right pump
The most challenging aspect of flood recovery is water extraction. We offer a variety of pumps suited for different conditions, helping you efficiently dry out construction sites or waterlogged footings.
Submersible Water Pump: If a river bank has burst and there’s lots of debris in the water, or you’re trying to clear through water that’s collected in trenches, these pumps are available in 50mm & 75mm (2 & 3 inches) diameter discharge. They are adept at handling large quantities of water mixed with abrasive materials like clay, sand, and drilling fines, so they don’t easily clog. They will pump water up from a trench or basement 10m deep at a flow rate of 225 litres per minute.
Residual Pump: Ideal for removing large amounts of water from flooded rooms and cellars. For cleaner water with minimal debris, such as domestic environments or new builds. These pumps are available in 25mm & 50mm (1 & 2 inches) diameter discharge. They effectively clear water down to 1mm and will pump water up 10m deep at a flow rate of 170 litres per minute.
Trash Pump: Petrol or Diesel powered with a maximum suction lift of 8m, this dirty water trash pump is ideal for clearing trenches and deep excavations of water and water-borne debris. The petrol-engine trash pump will handle solids up to 25mm in diameter and is capable of shifting over 1300 litres of water per minute. They are available in 50-75mm (2-3 inches).
Centrifugal Pump: In cases where power access is limited, our petrol-powered Centrifugal Pumps are excellent for pumping large volumes of clean water. They pump water up to 6m with a flow rate of 600 litres of water per minute. They are available in 50-75mm (2-3 inches).
Cleaning
Once most water is removed, especially indoors, residual cleaning can remove any lingering residue. Our industrial-grade Wet Vacuum Cleaner transitions from wet to dry cleaning, tackling mud or sludge left by floods. For carpet damage, our Carpet Cleaner offers deep cleaning with strong suction, leaving surfaces nearly dry in minutes.
Drying the Premises (floods inside)
Post-flood humidity can lead to dampness and mould. Our range of dehumidifiers, including the Self Pumping Dehumidifier, swiftly removes moisture from the air, ensuring efficient drying of walls and rooms. These dehumidifiers operate continuously, with a discharge pump for consistent moisture removal. Built for performance and reliability in tough conditions, we have a range of dehumidifiers in different sizes available.
For specific area drying, our Floor & Carpet Dryer, or surface drying unit, provides rapid, effective drying with an adjustable head, suitable for carpets, hard floors, and other surfaces.
To accelerate drying, hire powerful heaters to move the air and dry out the damage from the flood. Opt for an Electric Fan Heater to speed up the process, avoid LPG and gas variants as they can introduce unnecessary moisture.
Site Safety Information
Following a flood, safety is paramount. Adhere to HSE guidelines:
- Ensure the site is tidy, structures stable, and trenches secure.
- Establish effective drainage systems to circumvent extensive water accumulation.
- Keep pathways clear.
- In colder climates, continually run water through pipes to prevent freezing and bursting.
- In the event of flooding, deploy industrial pumps for water removal.
- Lastly, always have an emergency evacuation plan in place.
Flooding need not indefinitely stall construction. The right equipment, procedures, and safety measures can facilitate recovery and progress. Dealing with a flood? Find your local branch and get in touch with the Alliance team today.
