  • Can 2 cm ceramic slabs / porcelain stoneware tiles be laid on VARIO pads?

    As the cross-spacers with reverse motion locking (prod. no. 192145 4mm, prod. no. 192152: 6 mm) have a joint bar height of only 15 mm, ceramic slabs and porcelain stoneware tiles with a height of 18-20mm can also be laid on them with no problem.

    (Please contact your paving slab manufacturer to make sure that they can be laid on pads and keep to the manufacturer's recommendations.)

  • The paving slab breaks when laid on pads.

    Please contact your paving slab manufacturer to make sure that they can be laid on pads and keep to the manufacturer's recommendations.

  • What fire protection class do the pads and cross-spacers fall into?

    Flammability classification as per UL 94 = HB (equivalent to B2) 

  • What is the pads' load-bearing capacity?

    MAXI

    50.0 kN per quarter segment × 4 = 200.00 kN per pad (tested at 23°C and 50% relative air humidity)

    MULTI WITHMULTI+PLUS

    50.0 kN per quarter segment × 4 = 200.00 kN per pad (tested at 23°C and 50% relative air humidity)

    STANDARD

    50.0 kN per quarter segment × 4 = 200.00 kN per pad (tested at 23°C and 50% relative air humidity)

    VARIO / VARIO MINI

    at cogwheel height of 35 mm = 19.2 kN per cogwheel × 4 = 78.80 kN per pad
    at cogwheel height of 50 mm = 13.6 kN per cogwheel × 4 = 54.40 kN per pad
    (Tested at 23°C and 50% relative air humidity)

  • How high can (splittable and stackable) MAXI pads be stacked?

    All (splittable and stackable) MAXI pads can be stacked in any combination up to six-high on top of each other. 
    When stacking half pads please have regard to the compressive strength of the sub-construction

    MAXI pad 20/6x20 (prod. no 145417), 1-high

    MAXI pad 20/6x20 (prod. no 145417), 3-high

    MAXI pad 20/6x20 (prod. no 145417), 5-high

    MAXI edge pieces 20/4x20 (prod. no. 145325) stacked 4-high, on top a MAXI edge piece 10/4x10 (prod. no. 135227)

  • How high can MULTI- and MULTI+PLUS pads be stacked?

    All (splittable and stackable) MULTI pads can be stacked in any combination up to seven-high on top of each other. In order to compensate for a slope, it is also possible here to fit the VARIO (prod. no. 192169) or VARIO MINI (prod. no. 193166) with cross-spacer for reverse motion locking (prod. no. 192145 4mm or prod. no. 192152 6mm). In this case the maximum number is 6x MULTI or MULTI+PLUS and 1 VARIO or VARIO MINI. 

    When stacking half pads please have regard to the compressive strength of the sub-construction .

    One each of pads MULTI+PLUS (prod. no. 193074) and MULTI (prod. no. 193067) stacked

    Three each of pads MULTI+PLUS (prod. no. 193074) and MULTI (prod. no. 193067) with Vario-Pad 2 (prod. no. 192169) and cross-spacer for reverse motion locking 4mm (prod. no. 192145) stacked

    Six MULTI+PLUS pads (prod. no. 193074) with Vario-Pad 2 (prod. no. 192169) and cross-spacer for reverse motion locking 4mm (prod. no. 192145) stacked

    One each of a half MULTI+PLUS pad (prod. no. 193074) and half MULTI pad (prod. no. 193067) stacked

     

  • Are paving slab pads made of soft PVC UV-resistant?

    Yes, pads made of soft PVC are UV-resistant. And as most pads are laid underneath slabs they are hardly ever exposed to direct sunlight.
