Brick paving can be installed over existing concrete as long as it
is in fairly good condition. To ensure an adequate foundation for
the brick, the existing concrete slab or should be inspected and
repaired as necessary. Any large cracks, holes or dips should be
rectified in order to achieve a flat surface.
 The brick can be installed either
with or without mortar.
If mortar is used, you may consider
hiring a bricklayer for the job. If you do the job yourself, the concrete slab should
be prepared in the same manner as below. A 12mm mortar setting bed should then
be applied upon which the bricks are set with mortar placed between the pavers.
Only a small area should receive the setting bed at a time in order to ensure
that it does not set prior to laying the brick. If no mortar is used, a half-inch setting bed of coarse
sand should be laid, levelled and compacted. An edging of metal or heavy-duty plastic
should then be placed around the perimeter of the brickwork and set to just
below the height of the finished brick surface. Pavers can then be placed in a
wide variety of patterns on top of the sand. The bricks should be placed as close
to each other as possible and lightly bedded in with a soft mallet whilst
maintaining a level surface. It may be necessary to cut some of
the brick near the edging. Once the brick are all in place, spread
bricklayer's sand between the
bricks and over the surface. Sweep away excess surface sand and the job is
done. |
