Pumice Cable Stone
Cable Stone – Guide Brick 14×7×7 SBP-7
14×7×7 cm brick; set between cables and in narrow service-connection trenches.
Technical advantages
Line marker
Anyone digging reaches the stone before the cable, and knows a power line runs below.
Mechanical protection
A continuous row over the cable takes knocks from backfill and hand digging before they reach it.
Lightweight pumice
The pumice-aggregate body is carried by hand and laid quickly along the trench.
Long service life
It does not rust or deform underground; it stays put for decades.
Main areas of use
Power distribution
Low- and medium-voltage underground cable trenches.
Service connections
Cable trenches running from the network to each building.
Lighting circuits
Buried cables for street, park and estate lighting.
Urban renewal
Replacing existing infrastructure in redeveloped districts.
