The Vérindal B70 pedestal is designed to support a deck in natural wood or composite that needs levelling from 75 to 115 mm. Strong and durable, it supports a load of 1 tonne per pedestal at the centre and withstands both frost (-20°C) and UV (+80°C).
Like the other pedestals in the B range, its head is fitted with a 3-hole drilled tab, which lets you screw the joist directly onto it, with at least two fixing points.
The pedestal rests directly on the ground, without fixing, and is simply held in place by the weight of the joist on top of it. This loose-lay installation also ensures good ventilation of the structure.
Need a different height?
The Vérindal B range covers several heights, all with the same drilled-tab head. Each model has its own extension:
| Pedestal | Adjustment height | Compatible extension |
| B20 pedestal | 20 to 30 mm | RB10 extension (up to 40 mm) |
| B40 pedestal | 40 to 50 mm | R20 extension (3 maximum) |
| B50 pedestal | 55 to 75 mm | R20 extension (3 maximum) |
| B70 pedestal | 75 to 115 mm | R20 and R60 extensions |
| B100 pedestal | 105 to 170 mm | R20 and R60 extensions |
| B150 pedestal | 160 to 230 mm | R20 and R60 extensions |
The B70 pedestal is delivered assembled and consists of three main parts, all in 20% talc-filled polypropylene (recycled):
|
1
|
BH70 base : base of the pedestal
Ø200 × 49 mm, 110 g. Wide base for optimal stability on the ground.
|
|
2
|
EH70 nut : adjustment ring
Height 40 mm, 52 g. Screws onto the base to adjust the height precisely. Shared with the H70 pedestal.
|
|
3
|
TB70 screw : tab head
L120 × W61 × H71 mm, 73 g. Tab drilled with 3 holes for screw-fixing the joist.
|
Total assembled weight: 235 g
Before starting the job, draw a scale plan of your deck to calculate precisely the number of B70 pedestals, joists and wooden boards required.
Recommended spacing
Place the B70 pedestals every 50 cm along a first row, then step back 70 cm to lay a new row along the length of the joists.
|
1. Prepare the ground
On a concrete slab or an existing deck, install directly. On bare soil: dig 15 cm, lay a geotextile felt, backfill with crushed gravel, compact and check the level.
|
2. Position the pedestals on the ground
Lay a first row of pedestals every 50 cm, then a second row 70 cm further on, and so on up to the far end of the deck.
|
|
3. Fix the joists
Lay the joists on the pedestal heads and screw them down at a minimum of two points through the drilled tab. Set the height allowing for a slight slope for water drainage.
|
4. Lay the decking
Lay the boards perpendicular to the joists, starting against a wall with a 5 mm expansion gap. Screw 20 mm from the edge with special decking screws.
|
The B70 pedestal adjusts natively from 75 to 115 mm. To go higher, two extensions fit on the pedestal:
R20 20 mm extension
|
R60 60 mm extension

High wooden decks
Height of 75 to 115 mm, ideal for a marked levelling on a concrete slab or stabilised ground.
|
Natural wood and composite
Suitable for natural wood and composite boards, laid on joists.
|
|
Renovating an existing deck
Laid directly on an existing deck or a concrete slab, without major works.
|
Drainage and ventilation
The open structure of the pedestal prevents moisture rising under the wooden deck.

Yes. The pedestal rests directly on the ground and is simply held in place by the weight of the joist and the decking on top, with no glue or mechanical fixing into the ground.
The head of the B70 pedestal has a tab drilled with 3 holes. The joist rests on it and is screwed down at a minimum of two fixing points.
Yes, but always in the same order: the R60 extension(s) go first on the pedestal, then the R20 extension(s) on top for fine adjustment. The reverse order is not possible.
By adding R60 extensions (60 mm) on the pedestal, then, if you need finer adjustment, R20 extensions (20 mm) on top.
The B70 pedestal is suitable for natural wood and composite boards, laid on joists.
Space the pedestals 50 cm apart along a first row, then place a new row 70 cm further on along the length of the joists.
