Inspection lids

They stabilize ballistic columns, minimizing the formation of gaps between individual columns, as well as protect RUBOX ballistic columns against water penetration and loss of ballistic granules during changing weather conditions. Control windows in the inspection lids allow for monitoring of the ballistic granulate condition in the structure and for refilling of it by opening the inspection window

Inspection lids are available in three dimensional variants:

• a wall starter element – 25 cm x 2 cm x 30 cm (length x height x width),
• an element connecting individual blocks – 50 cm x 2 cm x 30 cm (length x height x width),
• a corner element for creating inside and outside corners of walls at an angle of 90 degrees – 55 cm x 2 cm x 30 cm (length x height x width)
