Langmatz modular structural pits and equipment vaults

Adaptable and robust solutions for underground services

  • Modular design for underground power distribution and other equipment
  • Sizes from 250 mm to 1400 mm
  • Lid load class B (8 tonnes) to class E (40 tonnes)


Langmatz modular pits are made in Germany and are engineered for a lifetime of over 40 years.

The use of structural foamed polycarbonate (SFPC) in a honeycomb modular design delivers outstanding performance under dynamic and static load conditions. The SFPC material is extremely strong, heat resistant, flame retardant and resistant to solvents including petrol, diesel and oil. It has been shown by independent testing to be completely non-toxic to ground water.

Langmatz modular pits withstand all foreseeable environmental conditions, including extreme temperatures, rain, salt, petrol and oil.

They also withstand all foreseeable mechanical conditions, including vertical and horizontal static and dynamic forces from trucks and accelerating / decelerating traffic.

Lids are available from AS3996 Class B80 for footpaths and driveways up to Class E400 for application in carriageways. Lids can be cast iron, galvanised steel, composite or paved.

The pit design eliminates the need for a concrete vault or collar, reducing time and cost on site. The head-frame can also provide for a height adjustable lid.

The modular design of the pit components provides for a huge range of applications, including building over existing services. Pit components are available in a range of lengths from 250 mm to 2200 mm.

Installation is made easy by the SFPC pit elements, which can be easily separated into layers for manual handling and reconnected as required. No tools are required, thanks to the design of the modular blocks and the provision of tool-free conduit knockouts.

Langmatz modular pits are used in huge numbers worldwide for a wide variety of applications, including electricity (for LV distribution, service connections, pop-up power supplies, cable jointing and cross bonding boxes) telecoms, water, gas and control gear.
