Circum – a new type of rehabilitation system for trenchless sewer rehabilitation. The innovative feature: damaged areas are effectively and permanently sealed from the inside, without any earthworks. The high-quality and corrosion-free stainless steel rehabilitation sleeve can be installed quickly and easily within minutes. The system is suitable for small to large diameters: different diameters and sealing methods are available for each application.

The inner sleeve adapts perfectly to the contour of the inner pipe wall and thus permanently seals the damaged area. The patented external seal of the rehabilitation sleeve prevents any debris flowing past it from sticking to it. Free from environmentally harmful lubricants!

Circum MINI Internal Rehabilitation Sleeve With DIBt Certification – For Small To Medium Diameters

The Circum MINI internal rehabilitation sleeve is a particularly effective way of rehabilitating cracks and pipe connections easily and cost-effectively without earthworks. The method used is based on the principle of compression sealing. The stainless steel sleeve is positioned at the damaged area with the help of a rehabilitation packer and then pressed against the pipe wall until a sealing effect occurs. The area between the sealing nubs is thereby completely and permanently sealed.

Due to the design with patented external closure, there are no protruding obstacles inside the rehabilitation sleeve where debris flowing past could get stuck. The sleeve is designed for an internal pressure of up to 16 bar and is available from EPUTEC in pipe diameters from DN 150 – DN 800.

The system has been tested by the IKT for high-pressure flushing resistance and watertightness at external pressure.

Sealing of longitudinal and radial cracks, leaky pipe connections, missing wall sections, closing of unused laterals, part formation , replacing missing formwork behind inliners.

Circum-LEM Linerendmanschette mit DIBt-Zulassung

Circum LEM Liner End Sleeve With DIBt Certification

The Circum-LEM liner end sleeve with external closure was developed to seal liners and pipes effectively and sustainably and to prevent water from running behind them. The method used is based on the principle of compression sealing. Due to the patented, external closure of the liner end sleeve, there are no protruding obstacles inside the sleeve that could damage the sleeve during cleaning work, and no debris can get stuck.

The mechanically insertable liner end sleeve made of stainless steel is available in pipe diameters from DN 150 – DN 400 and reliably seals pipes, liners, manholes and structures. Supplied fully assembled and ready for installation. Free of environmentally harmful lubricants.

Connecting and sealing liner ends on pipes and structures, protecting vulnerable liner ends.
