Pavement Box Installation
Prior to installation, obtain 25 kg (50 lb.) of pea gravel and one brick for each corner
of the box. The bricks provide direct ground support for the EMU to prevent it from
sinking into the gravel.
z Dig the trench approximately 20 cm (8 in.) deeper than the depth of the box.
z Add 15 to 20 cm (6 to 8 in.) of pea gravel or crushed rock to the bottom of
the trench. The gravel provides drainage for the EMU.
z Place the pavement box in the trench with the top surface at grade level.
z Fill the trench and compact the soil until it is level with the cover on the
pavement box.
z If the grade level is raised later (through landscaping, etc.), a straight-sided box
can be pulled up and bricked at the bottom on one or four sides to conform to
the landscape.
You will need the following tools in order to install the pavement box:
z a heavy duty hammer drill,
z a 1 in.

2 ft (25 mm

0.5 m) carbide bit to fit the heavy duty hammer drill,

z a 1 in. (25 mm) masonry trowel,
z an Allen wrench to fit the seal-off fitting close-up plug,
z rubber gloves to wear while using cement and seal-off compound,
z a narrow sharpshooter shovel for trenching,
