Reinforced concrete (RC, RC) drainage trays: types, sizes: varieties, standard sizes and prices

When it comes to controlling surface water runoff, reinforced concrete drainage trays are crucial. In order to stop flooding and water damage, these trays—also referred to as drainage channels or gully drains—are made to gather and direct water away from surfaces. They provide a workable solution for efficient water management and are frequently utilized in a variety of contexts, including industrial areas and residential driveways.

Reinforced concrete drainage trays come in a variety of forms, each designed to meet specific requirements in various settings. The size, form, and load-bearing capacity of these trays vary, so it’s critical to select the appropriate kind for your particular project. You can choose the best option for effective water drainage by being aware of the various varieties and their uses.

These trays come in standard sizes to meet most installation needs, but custom sizes can also be ordered to satisfy special requirements. The type, size, and design of the trays, along with extra features like gratings or unique coatings, all affect pricing. Making an educated choice about your drainage needs can be aided by researching your options and knowing associated costs.

Type Size Varieties Standard Sizes Prices
Standard RC Drainage Tray 1000 mm x 500 mm Rectangular, slotted 1000 mm x 500 mm, 1000 mm x 250 mm $50 – $100
Heavy-Duty RC Drainage Tray 1200 mm x 600 mm Reinforced, with grates 1200 mm x 600 mm $80 – $150
Custom RC Drainage Tray Varies Custom shapes, sizes Customizable $100 – $200

Reinforced concrete drainage trays

Vibration pressing or vibration casting are the methods used to create reinforced concrete drainage trays (sewage, gutter). High-quality, heavy concrete is utilized. Because of the Class A steel reinforcement inside, the product has a high load-bearing capacity and strength.

Better features and longer lifespan distinguish a vibro-pressed gutter from a vibro-cast gutter. The products’ ends are designed with a locking connection to stop drainage system components from moving around during installation and use. The bottom of the tray may have a hole for vertical drainage into the sewer.

Varieties

Reinforced concrete drainage trays are identified by their installation method:

Gutter classification based on section shape:

  1. U-shaped – have the largest cross-sectional area, designed to drain a large volume of wastewater.
  2. U-shaped — designed to drain a small amount of wastewater, suitable for private suburban areas.
  3. Trapezoidal — for installing a telescopic drainage system. The product has the shape of a trapezoid not only in cross-section — one of its ends is wider than the other, and the narrow one is inserted into the next element.

Advantage of reinforced concrete products

In addition to reinforced concrete, drainage gutters can also be made of plastic, polymer-sand mixtures, simple concrete, and polymer concrete.

  • resistance to high loads;
  • wide range of applications;
  • low price.

Concrete trays

Concrete products without steel reinforcement are an alternative to trays made of reinforced concrete. Although they weigh significantly less, they are easier to transport and install even though they are less durable.

Concrete gutters are suitable for installation as extra components of the drainage system in parks, private homes, and summer cottages, but they are not meant to support large loads.

Sizes

The same standards are followed by every manufacturer of reinforced concrete trays. Apart from dimensions (L, B, and H), products are further categorized based on their hydraulic cross-section (DN). These factors establish the drainage system’s capacity to carry water.

Using a unique formula, a hydraulic calculation is done to find the necessary dimensions. Since there are a number of considerations to make, it is best to leave this task to the professionals. Large manufacturers provide free drainage system calculations to customers for areas up to 1000 square meters.

Only the weight and mass of trays are considered when determining the costs associated with transportation and installation because they are dependent on both the size and the load class:

European standard EN 1433

Based on the maximum load they can support, reinforced concrete drainage trays are categorized in compliance with European standard EN 1433.

Designation Permissible value, kN Application areas
A15 15 Private plots, squares, parks, pedestrian zones and sidewalks, bicycle paths.
B125 125 Motorcycle traffic areas.
C250 250 Parking lots, garages, light-duty highways.
D400 400 Industrial areas, petrol stations, car washes, transport terminals, other areas of truck traffic.
E600 600 Piers, warehouses, railways.
F900 900 Airfields and airports, military bases, cargo terminals, other areas with increased road surface loads.

Gutters in the F900 class are strengthened on the sides, perhaps with a strip of galvanized steel. Products with gratings of a higher class or concrete covers can be used in areas where the load is equivalent to the cover class.

For instance, class B125 gutters coated in class C250 products are appropriate for installation beside roads with light traffic in parking lots. There is a maximum of one level difference in cover load class.

In conclusion, drainage trays made of reinforced concrete provide a strong and practical way to control water flow in a variety of situations. They are appropriate for both residential and commercial applications since their design and construction guarantee that they can withstand heavy loads and challenging environmental conditions.

Choosing the ideal tray for your needs requires an understanding of the various types and sizes that are available. There is a selection to choose from to meet the needs of your project, regardless of whether you’re working with standard sizes or require something custom.

Size, type, and manufacturer can all affect price, but being aware of your options will help you choose wisely. Purchasing the appropriate drainage tray extends the life and functionality of your drainage system in addition to improving water management.

Drainage trays made of reinforced concrete are essential for controlling water runoff and averting flooding. They are available in different sizes and types to meet different needs; standard sizes work well for most applications, while more specialized varieties are available for specific needs. Knowing these options will help you choose the most cost-effective and efficient drainage tray for your project. This post will examine the various varieties, dimensions, and cost ranges of reinforced concrete drainage trays and provide helpful advice for making an informed selection.
