plate vibrator

The plate vibrator or 'Thwacker' can be hired from most plant hire shops.

Don't hire the heaviest plate vibrator you can get, thinking that it will speed things up by settling the bricks in one pass.

You can lay cold-roll macadam over old concrete, paving or existing macadam to give it a new surface, but it's difficult to lay over hardcore with an ordinary garden roller - you need to put down two layers and use a hired plate vibrator to get a good result.
