The base for laying K135 on is to be 150mm lower than the required
finished height. Set the K135 up on either lean mix concrete or a mix
of sharp sand and cement. To use K135 for 200mm thick concrete the
bedding mortar is simply thickened:
1.
Put string line down.
2.
Cut first top strip in half and attach to first shutter and fit end-clip.
3.
Place spots of bedding mortar on sub-base at intervals of 800mm to correspond
with holes in base.
4.
Place shutter on mortar and gently tap down with a rubber mallet so that the top of the wear strip is at the desired level.
5.
Place bedding mortar as above for next shutter.
6.
Join second shutter to first with the end-clip.
7.
Fit full length of top strip across the shutters.
8.
Tap down the shutter as above.
9.
Once the bedding mortar has cured, you can start pouring concrete.
10.
Each 3m K-FORM beam has pre-drilled 20mm holes for steel tie bars.
11.
K-FORM stays is place, therefore adjoining bays can be poured one after the other.
12.
When the concrete has cured, remove the top strip and fill gap with sealant.
Top strip can be left in if preferred.
