What are PRORAM industrial-grade linear drains made of?Our linear drains are built from modified HDPE plastic for the channel body and feature heavy-duty cast iron covers, ensuring durability, strength, and resistance to corrosion.
-
What is HDPE and why is it used for C250 linear drains?HDPE (High-Density Polyethylene), is a strong, lightweight, and highly durable thermoplastic polymer made from petroleum. It is resistant to corrosion, chemical exposure, impacts, and extreme weather conditions. In our C250 linear drains, HDPE is used for the drain channel body because it provides exceptional structural integrity without the heavy weight of traditional concrete or metal systems. This makes installation easier, reduces maintenance needs, and ensures a long service life even under challenging conditions such as parking lots, streets, and sports facilities. Combined with a heavy-duty cast iron grate, the HDPE channel offers the perfect balance between strength, durability, and efficiency for high-traffic drainage applications.
-
What load capacity do PRORAM'S linear drains support?PRORAM’s industrial-grade drains are certified BS EN 1433 Load Class C250, meaning they can withstand up to 25 tons of weight, ideal for streets, parking lots, and high-traffic areas.
-
Are your linear drains suitable for residential use?Yes! Although built for industrial-grade performance, our drains are equally effective for residential projects like driveways, patios, gardens, and retaining walls.
-
What connection options are available for your drain systems?Our drains use a simple male/female connection system with nine base outlet positions per channel. We also offer versatile quad connectors for easy corner and junction installations.
-
How do PRORAM linear drains prevent clogging and improve safety?Our standard heelguard grates provide excellent water flow while preventing debris buildup and ensuring pedestrian safety, even in busy areas. To keep your drainage systems performing at their best, PRORAM also offers professional maintenance and cleaning services as part of our ongoing support.
-
Can the linear drains be customized for different project needs?Yes. We offer modular options like corner joints, slim pits, and end caps, allowing us to tailor the drainage system to your specific site layout and requirements. If you need help with the installation, learn more about our Installation services.

How do I know if my property needs a new drain installation or sewer connection?Signs like frequent water pooling, basement dampness, slow drains, or outdated infrastructure usually indicate the need for a new drainage or sewer connection. A professional assessment is the best way to determine the right solution, so give us a call to determine your needs.
-
What’s the typical process for installing a new drainage system?First, we conduct a site evaluation and soil analysis. Then we design the system, handle any required permits, prepare the site through excavation or demolition first if necessary, and install the drains or pipes, and complete the final backfilling and cleanup.
-
How is a sewer connection different from regular drain installation?A sewer connection links your property directly to the municipal sewer line, requiring strict compliance with city regulations, while a standard drain installation often involves managing groundwater or surface water on-site.
-
What should I consider before starting a drainage or sewer project?Factors include soil type, property slope, proximity to existing utilities, local building codes, and the potential for future expansion. Our team helps guide you through all planning aspects during the consultation.
-
Are there specific regulations for connecting to the city sewer system?Yes. Every municipality has technical standards for sewer connections, including pipe materials, installation depths, backflow prevention, and inspection requirements. PRORAM ensures full compliance with all local regulations.
-
How durable are the drainage and sewer systems you install?We use premium materials like C250 drains, high-grade PVC piping, and certified waterproofing DELTA membranes to ensure maximum durability, longevity, and resistance to environmental stressors. Our Industrial-grade C250 linear drains have a galvanized metal grill with a cover in cast iron for durability and to withstand extreme weather conditions, while the channel body is made of modified HDPE. It can also support about 25 tons of wight load capacity.
-
Can you integrate drainage improvements with other site works, like landscaping or foundation upgrades?Yes, we can coordinate drainage system installation with landscaping, foundation waterproofing, grading adjustments, or other construction improvements for a complete, integrated solution.

Why Is Regular Drainbox Cleaning Important?Regular sewer cleaning helps prevent blockages, reduces the risk of flooding, and ensures your drainage system operates efficiently. Without regular maintenance, buildups can cause clogs, leading to expensive repairs, health hazards, and property damage. Scheduling professional sewer maintenance keeps your drainage system functioning optimally. Learn more in our article on How to Prevent Sewer Blockages.
-
How Often Should I Have My Sewer and Drainbox Cleaned?For most residential properties, it's recommended to have your sewer and drainbox cleaned once every 1-2 years. However, if you have older plumbing or experience frequent drainage issues, you may need more frequent maintenance. Commercial and industrial properties, due to heavier use, might require more regular servicing.
-
What Causes Sewer and Drainbox Blockages?Sewer blockages can be caused by a variety of factors, such as grease buildup, non-biodegradable items like wipes or hygiene products, root intrusion from nearby trees, and sediment accumulation. These factors obstruct the flow of wastewater and can cause significant problems if not addressed. Read our article on How to Prevent Sewer Blockages for more details.

What Equipment Is Used for Sewer and Drainbox Cleaning?We use state-of-the-art equipment, including vacuum trucks and high-pressure water jetting systems, to provide a thorough and effective cleaning of your sewer lines and drainboxes. These tools are specifically designed to handle a variety of clogs, including tough sludge, grease, and debris. A vacuum truck is a specialized vehicle equipped with a high-powered vacuum system that extracts debris, sludge, and waste from sewers and drainboxes. This ensures a deep clean and prevents future blockages by removing accumulated material efficiently.
-
What Happens If I Ignore the Warning Signs of a Clogged Drainbox?Ignoring the warning signs of a clogged drainbox, such as slow drainage or water backups, can lead to severe flooding, property damage, and increased repair costs. Blockages can also contribute to unpleasant odors and attract pests. It's important to address these issues promptly to avoid costly damage and maintain a healthy environment.
-
Are There Different Maintenance Needs for Residential, Commercial, and Industrial Properties?Yes, residential, commercial, and industrial properties have different maintenance needs. Residential properties typically require less frequent cleaning, whereas commercial and industrial sites, due to higher volumes of waste and heavy-duty usage, need more regular and specialized maintenance. Our services are tailored to meet the unique needs of each type of property to ensure efficient operation and compliance with safety standards.
-
What Should I Do If My Property Is Flooding During Rainfall?If your property is flooding during moderate rainfall, it could indicate a blocked drainbox or an overwhelmed drainage system.
