Sapodrain channels should be laid on a foundation of concrete as illustrated.
Place the channels and align them on a foundation of concrete, always starting from the outlet. Take care to lower each channel vertically in the groove of the previous channel. When laying a string of channels with fall in opposite directions the protruding grooves of the middle pair of channels must be removed with a grinding-machine before being laid (fig.1). Ensure that the concrete surround is 3-5 mm above the level of the channels.

With fall to a central point and the outlet in the middle the grooves will not engage but the channels will butt up to each other. When the channels are laid and aligned place the concrete on either side. .

Graitings or boards (20x128 mm) shall always be laid on the channels when concreting and when carrying out the top layer/surface. In general we recommend the use of the boards, specially in connection with clinker concrete and synthetic materials (fig 3). This will prevent the edges of the channels being pressed too hard towards the gratings during the compacting of the concrete and reduces the amount of cleaning necessary after installation. It also protects the gratings and the channels

The basis for a successful and durable system is choosing the right materials, the correct load rating or class, the correct installation.
Comparatively thin-walled channel components as Sapodrain A10 are constructed in such a way that the physical strengths from the traffic load are transferred to the concrete in which the channels are laid (Fig.A)

For installations with paving stones laid adjacent to the channel it is important not to use sand up the channel, partly because sand cannot resist the loads which are transferred trough the wall of the channel by load traffic and partly because a vertical pressure on the paving stone laid in sands corresponds to an horizontal pressure on the wall of the channel (Fig.B).
The Sapodrain A10 is provided as standard with PP/COP plastic edges. A10F with cast iron frame or A10RS with stainless steel edges are also available.

Outlet
For vertical outlet directly from the channel remove the outlet recess by striking from the inside out. Insert the PE union in the outlet before placing the channel. A recess is provided for mastic or adhesive to seal the vertical outlet.
Tight channel seals
Where a seal between channels is required, ie for "floor-decked" space or for special environments, use the built-in joint track to ensure tighter channel connections. Sealing is easily done by using a masticgun and a suitable adhesive. When complete the seal is cincealed and protected against any mechanical overload.

The channels have an integral grating lock "Easy Lock". Activate the lock by pushing the lock-spring into place in its holder in the channel before placing the grating. The lock will engage when the grating is put into place on the channel and is "stepped on". For gratings class E and F a stud will be supplied. Mount the grating either before the channel is laid or when the concrete foundation is hard enough is hard enough to support the load which occures when the grating is stepped in place in the groove.

Where paving stones are used adjacent to the channel the row of stones immediately adjacent to the channel must be laid in the concrete foundation surrounding the channel. When using asphalt covering close to the channel the thinkness of the bitumen closest to the channel must not be greater than 30 mm. The bitumen to be laid proud to compensate for settæement resulting from subsequent traffic load. When installed in a larger concrete area wxpansion joints must be established, parallel with and a maximum of 1.5 to 2 metres from the channel, and perpendicular to the channel opposite a channel joint every 8 metres, maximum spacing.

The Sapodrain A10 System is provided with PP/COP plastic edgings.
It is recommended to use stainless steel edgings to secure an optimal adherence for clinkers or covering in synthetic materials. For asphalt covering or paving stones close to the channelcombined with a traffic load ckass C, E or F always use a cat iron frame.
