Mortar-less paving repair

brickpaving-nomortar crazypavingOver the years ground settles and heaves.  Anything that is not completely engineered to withstand this movement will move with it.  Commons areas that suffer from this type of movement are mortar-less crazy paving and brick paving.

When they are first installed these paving surfaces present a pleasing  landscape and are considered more aesthetic than poured concrete.
Over the years, time and nature take their toll and deterioration of different sorts can cause the surfaces to become uneven and a trip hazard.
If the sole cause of the sinking is only ground settlement , repairing these surfaces, although time consuming is not difficult, and does not cost vast sums of money if you are able to perform the paving repair work yourself.

The tools you will need are minimal, A large hide or rubber mallet, A carpenters level is preferable or a 6 foot straight piece of 2×4 lumber if not.  A pry bar for lifting the pavers and a shovel and broom. 
The material you will require is all purpose sand for under the pavers and polymeric sand for the joints.

DIY enthusiats may want to hire a plate compactor from a DIY store, but this is not necessary is care is taken when performing the work and can sometime end up breaking pavers on an old paved area.

  1. Remove any loose, broken or sunken pavers. If your examination shows that adjacent pavers have not been displaced, but that settlement has occurred beneath them as well – so that they are not sitting squarely on the base – they should also be removed.
  2. Fill the depression with all purpose sand re-siting the paver and using the level to match to the desired height.  When the correct level is achieved Set the pavers back into place. Check their level with the surrounding pavement with the carpenters level or 2 x 4. If the pavers are not level, tap them gently to seat them. Replace any broken pavers.
  3. Spread polymeric sand over the repaired area and sweep it into the joints. Dampen the sand with a fine spray; repeat until the joints are completely filled.
