Concrete manholes
manhole rings
Manhole rings can be used to build suitable manholes for a wide range of applications. EK-manhole rings are also available.
manhole base rings
High-quality manhole base rings are designed to withstand Finland’s demanding weather conditions. EK base rings with integrated gaskets are also available.
EK-Base Rings with Channel Base
EK base rings with a channel base are used in inspection manholes for wastewater and stormwater pipelines, as well as in other applications where watertightness and durability are required from the manhole.
Cone rings
Standard cone rings and EK cone rings with integrated gaskets enable a variety of solutions to meet different project requirements.
EK Telescopic Cones
With the EK-telescopic cone, we have combined the best features of a concrete cone section and a telescopic cover assembly!
manhole covers
Reinforced manhole cover with an integrated gasket, suitable for traffic load areas. Available as a solid cover or with a circular opening positioned either centrally or at the edge.
Extension Rings
Grooved-joint riser rings designed for manhole height adjustment and/or final ground level adjustment. Riser rings are also available with a bevel to match road crossfall or surface gradients.
Cast Iron Cover systems
Our standard range includes cast iron cover systems compliant with the 550/30, 550/50 and 600/40 standards, available with either a solid cover or a grating cover, with a load class of 400 kN.
partition walls
A manhole can be divided into separate compartments using a partition wall. If required, the partition wall can be cast with the desired T-pipe connection, for example in septic tanks and separator manholes.
Pipe Entries and Connections
Our extensive product range also includes manhole entries and connections. Entries with rubber seals are available, for example, for plastic pipes.
