Angerlehner Hoch- und Tiefbau Gesellschaft mbH ∙ www.angerlehner.com
Preparatory works
Preparation works are crucial for purposeful
and cost efficient pipe rehabilitation
• CCTV
• Analsis of sewer condition
• Qualified engineers evaluate the pictures
immediately
• Rehabilitation concepts are elaborated
• Client receives most relevant data about the
condition of sewer and a cost estimation for the
rehabilitation

MCS Inliner
Dimensions: DN 300 – 3,000 mm
Area of application:
Drains, storm water, sewer
Profiles: Circular, egg, ovoid, and the like
Length:
Rehabilitation up to 500 m per
installation pit, reaming performance up to 6
m/hour (with AKF reaming machine)
Pipe materials:
Reaming only possible in brick sewer or in
situ concrete pipes
Angerlehner Hoch- und Tiefbau Gesellschaft mbH ∙ www.angerlehner.com
MCS Inliner – Phase 1
Assessment of existing sewer (pipeline)
• Wall thickness check
• Documentation of:
– Cracks
– Infiltrating water
– Loose bricks
– Root ingress
– Other observations as per prevailing standards
(e.g.WRc)
• Economic rehabilitation concept elaborated
Angerlehner Hoch- und Tiefbau Gesellschaft mbH ∙ www.angerlehner.com
MCS Inliner – Phase 2
Expansion of the existing pipe
• AKF reaming machine
• Increase of cross-section up to 35% possible
• Cutting depth up to 14 cm in a single work
cycle
• Machine is computer controlled
Reaming profile of the AKF - 3 frame sizes
• AKF 11: 600 / 900 - 750 / 1,050 mm
• AKF 22: 750 / 1,050 - 900 / 1,350 mm
• AKF 40: 900 / 1,350 - 1840 / 2,800 mm
Angerlehner Hoch- und Tiefbau Gesellschaft mbH ∙ www.angerlehner.com
DEWATERING –
EARLY WARNING SYSTEM
• Detects increase of water level
• Up to 5 kilometers away from the
construction site
• Warning to foreman
• Workers have about 10 minutes to
evacuate the sewer
Angerlehner Hoch- und Tiefbau Gesellschaft mbH ∙ www.angerlehner.com
MCS Inliner - Phase 3
Installation of the liner
• GRP pipes or other materials
• Insertion into installation shaft using a crane
and moving liner into position
• House connections are opened up and bound
thight

MCS Inliner – Phase 4
Grouting of the annular gap
• Grout has an excellent flow-capacity and is
shrinkage compensated
• Grout is delivered with pumps using hose pipes
and brought in via grouting holes in the pipe
• Fill the annular gap
• Durability
• Increase the load bearing capacity
• Grouting is done in sections and layers
• Closing of launch shaft

Cured-in-place pipe
Details
Dimensions: DN 100 – 1,200 mm
Area of application: Sewer and water pipes, gravity
and pressure lines, gas lines
Profiles: preferably circular profile,
egg profile
Length: Sections up to 250 m
Pipe materials: Stoneware, fiber cement, cast,
concrete, PVC, GRP
Advantages
• Economical solution for non-accessible profiles
• Exceptional chemical resistance
• Resistant to age, dimensionally stable
• Good hydraulic characteristics
• Seamless pipe
Angerlehner Hoch- und Tiefbau Gesellschaft mbH ∙ www.angerlehner.com
Cured-in-place pipe
• Liner is saturated with resin
• Liner is fixed on the inversion stand and
inverted into the damaged sewer via manhole
channels, using the hydrostatic pressure of hot
water
• Subsequently curing of liner
• House connections are re-opened precisely by
robots
Angerlehner Hoch- und Tiefbau Gesellschaft mbH ∙ www.angerlehner.com
Pipe bursting
Details
Dimensions: DN 65 – 1,000 mm
Area of application: Drinking water pipeline, gas
line, drains and seep water
pipes, pressure pipes
Profile: only circular profiles
Length: Sections up to 150 – 200 m / day
Materials: Steal, grey cast iron, fiber
cement, concrete, PE/PVC,
stoneware
Advantages
• Enlargement of cross section between 1 and 2
dimensions (e.g. DN 80 to DN 90)
• Flexible and Reliable
• Insensitive to groundwater infiltration
