Advantages over traditional drainage system

1). Light weight compared to size, cost of transport and installation.

2). Robust, unbreakable to bumps and falls.

3). Yisitong Drainage Channel Polypropylene drainage channel with galvanised steel covering can be used in the field temperature from -60C to +100C without damage.

4). Chemically resists a wide range of acids, salts and hydrocarbons. Installdrain Polypropylene drainage channel with galvanised steel covering can also be used in special environments such as chemical plants, workshops and service stations and is particularly suitable for roads with use of intensive salt anti-freeze, destructive to most traditional systems.

5). Surface resistance to mold and microorganisms means Installdrain can be used in all structures that require high hygiene such as flooring in kitchens, food processing industries, hospitals, etc.

6). Coefficient of peak flows, the surface area of the Installdrain does not create barriers to water flow and minimizes the storage of aggregates.

7). The system is very versatile as the same channel can be installed with different grate options from Class A to Class D.

8). Preformed discharge outlets located on the bottom and side panels of the channel, allow quick and simple connection to storm water discharge pipes.

9). The possibility of mounting grooves with the fixed grate, makes it extremely fast to install. You can transport the pipeline system (channel and grate) already packaged for quick use.
