Advantages over Traditional Systems
•
•
The channel represents the technology of Technodrain from Asoplast, demonstrating decades of
experience by their designers in the field of drainage. All solutions techniques and construction
details were marked to provide an end –user product that is light, safe and easy to install.
Technodrain wins the challenge compared to traditional systems, thanks to its versatility and
affordability of installation, strength and durability of its structure. The HDPE (High Density
Polyethylene) makes it light weight and immune to chemical attack.

ADVICE FOR THE INSTALLATION OF TECHNODRAIN
DRAINAGE SYSTEM
Step1.LoadClassRequest
The first step in designing a drainage system is the choice of grate.These choices are
based on the characteristics of load resistance the channel grate must endure, the
architectural finish preferred, and the surface water capture characteristics in relation to
thesizeofthegrate.TheloadclassesforthegrateoptionsarespecifiedinAS:3996.
The Specifier should also pay attention to potential future changes of use of an area which
may be subject to heavy or construction loads (e.g.: Semi Trailers or earthmoving
equipment) which may necessitate selecting grates suitable for higher load class rating.

Step 2. Design of drainage system
The collection and drainage system should be sized according to the rainfall and
meteorological characteristics of the site concerned, size, shape and slope of the
catchment area, type of surface used (asphalt, concrete, paving, lawn, etc.), and the
properties of the runoff liquid being captured.
Attention should also be paid to access roads or roofs that may concentrate water into the
catchment area being considered as the total flow to disposal will be the summation of all
these components.

Step 3. Laying
The Technodrain channel and grate system requires a base of concrete thick enough to
spreadtheverticalandhorizontalthrustloadsinaccordancewiththeClassratingofthe
grate selected.
A. Preparing the ground for installation:
The excavation for the installation of the drainage system Technodrain must be
dimensioned taking into account the channel selected and thickness of concrete required
fortheabutmentandthesubstrateasgivenintable1.Inadditiontothesethicknesses(R
and S) the excavation should allow for the possible passage of pipes to the final drain
connection. The natural ground the drain is being laid in must have a bearing capacity
sufficienttosupporttheloadclassesselected.Itmaybenecessarytoincreasethe
bearing capacity by tamping down the foundation or providing some form of ground or soil
reinforcement. In particularly soft sub grades may be necessary to make the
concrete foundation wider to provide a greater support area.

C.Installationofchannel
For the proper installation of the Technodrain channel, begin the installation from the point of discharge (well),
connecting the outlet to the stormwater system. For a perfect seal of the

Adhesive. The channel should be installed with Technodrain grates already in place, it is therefore
recommendedtoperformthisoperationbeforelocatingthedrainintheexcavation.Careshouldbetakenin
ensuring the correct placement and orientation of grates on the channel before
tightening the fixing screws.
To connect storm water pipes to the Technodrain channel,
drill out the required size hole in the bottom, side or end
cap located on the channel using the appropriate sized
hole saw to suit the size of the discharging storm water
pipe.Removeanyroughedgeslocatedaroundtheinside
