WHAT FOR

The technological objective for relieving slab COMPO is to boost the capacity of use of plastic manholes.  

WHAT OF

• Relieving slab COMPO is made of reinforced armored concrete.
• The slab is designed to be used in the zones of extremely high loads (cargo terminals - ports, piers, airports).
• Equivalent load in design comprises 900 kN/90 t (F900).

WHY

When loaded, the concrete slab works as a single element, distributing the load evenly, barring damage and fully preserving every element in the structure of the manhole, hatch and trunk..
