Flexi Grillage is the new range of products to be released by Flexi Group which will enable AOV, dry riser openings, or even drainage openings to be cast into slabs with the minimum of fuss.
2mm thick pre-formed mild steel galvanised channels, manufactured to the depth of the concrete slab form the opening void. The channels are formed in the top with a recess of your choice, which will enable either a flow-forge type grillage or a GRP type grillage to be clipped into the top and form the opening.
​
The channels are supplied to site with reinforcing bars already welded to the sides, which will provide enough strength to tie the channels into the slab. The Formwork Contractor then places the channels in the correct location, ties into the adjoining wall and pours the concrete - Flexi grillage will provide the permanent formwork.
using a grillage often permits valuable time savings.
Avoidance of poured concrete saves time and simplifies installation.
Through minimal disruption of transport infrastructure.
The technology suits many different applications.
