It is alluring to turn a plain concrete area into a lovely hardwood deck since it transforms your landscape. Give in to the temptation! The installation of wooden slabs on blocks does not present any particular difficulty, just a little attention to leveling.
We advise you to choose height-adjustable blocks to facilitate the leveling of your deck.
A terrace on blocks is installed on a concrete slab flat, with a slight slope for rainwater drainage.
Here is a step-by-step guide to installing a wood slab deck.
1. Determine the number of slabs and blocks needed
Here are the materials you need to build your deck:
– screw-in height-adjustable posts with 4 compartments at the top, separated by fins, to support the slabs at their corners;
– wooden slabs of 50 × 50 cm.
Start by taking measurements:
– Determine the area of your deck.
– Using a tape measure, measure the width and length (and other dimensions in the case of a more complex geometry).
– If possible, try to avoid cutting the tiles.
– Estimate the number of tiles needed, and deduct the number of studs from this.
– If necessary, use a plan to help you.
2. Lay the first slab
– Start laying the tiles at the outermost corner of the terrace (i.e., the corner that does not lean against a wall).
– Place the 4 blocks on the ground to receive the corner tile.
– Remove with pliers the 4 wings of the corner block and the 2 wings opposite the edge blocks.
– Place the first tile on the studs.
– Check that it is flush with the edge of the terrace with a square.
– Tuck the edge blocks inward, so they do not extend beyond the deck.
– Check the level of the slab with a spirit level.
– Adjust the height by screwing or unscrewing the studs.
3. Lay the following tiles
– Continue the installation of the row at the edge of the terrace.
– Place the next 2 studs on the ground to receive the second tile.
– Remove 2 fins from the one at the edge of the terrace.
– Lay the second slab, reversing the direction of the boards to the first for a final aesthetic result.
– Continue until you finish the row.
– As you go along, check that the tiles are horizontal.
– Then cover the entire surface, row by row.
4. Cut the tiles if necessary
To go along a wall
– Take the dimensions of the slab to be cut.
– Draw the cut line on the slab with a pencil.
– Block the slab on the workbench with the clamp.
– Put on protective glasses and gloves.
– Cut with the circular saw and a suitable wood blade.
Caution: a circular saw is dangerous; it runs at very high speeds, so be careful.
To bypass an obstacle (e.g., downspout)
– Mark the dimensions on the slab.
– Block the slab on the workbench with a clamp.
– Cut the slab with a jigsaw equipped with a wooden blade.
– To increase the stability of the cut tile, consider using an additional block with its wings removed.
5. Install the finishing border
– Measure the length of the sides that do not rest against a wall.
– Plan a wooden border to be planted on this perimeter.
– Hammer it in so that the top of the edging is flush with the deck’s surface.
– Your deck is finished. Now, all you have to do is install your deck chair!
