Paving slab pads

Want to lay paving slabs on a surface that has height differences? Enter MAXI, our stackable pad!

The PLATTENFIX MAXI-Pads offer you all the advantages of the STANDARD-Pads, but can also bestacked to level out differences in sub-surface height. Please make sure when stacking that for all pads the joint width is identical. 

Up to six stacked MAXI pads overcome a height difference of as much as 12 cm. 

For finer degrees of unevenness, combine the MAXI pads with MAXI shims – in that way you can even out a further three millimetres. Laying is as easy as with STANDARD pads: At edges and in corners PLATTENFIX pads can easily be split into half or quarter pads. Alternatively, for the corners you can opt to use a ready-made MAXI edge piece.

Laying instructions

Laying slabs using PLATTENFIX pads is always done following the same principle, which we show you on this page. On the following pages we then respectively look at the different PLATTENFIX pads.

We recommend that first of all, using suitable tools and equipment, you sound out the maximum top edges of the paving so that you can see what height difference needs to be bridged using additional shims. 

You should then look for a crossways and lengthways side in order to establish a right angle for starting to lay the slabs. We recommend utilising two outer edges (eaves/parapets or similar) in order to begin laying whole slabs, extending out from those edges, out of the corner within the right angle.

AThe slabs to be laid always have one corner lying on a quarter segment of paving pad; at the outer edges Bhalf pads are fitted so that here too the slabs are lying on a quarter piece. CQuarter pieces are laid in the corners. 

By the way: the STANDARD and MAXI pads can be easily cut in half or into quarters using a craft knife. For VARIO and MULTI pads use wire cutters. For large-format slabs that have to be centrally supported, you can fit STANDARD and MAXI with no joint bar.

D The area to be paved should be dividedup in such a way that no slab that gets cut to size is smaller than 16 cm.

Note that when laying MAXI pads on an existing liner, you must add a barrier made of weather- and UV-resistant PE sheeting or glass fibre matting with a total weight of at least 200 g/m².
