The constant improvement of our high-quality standards, occupational safety and environmental performance is essential for Epping’s corporate policy. The fulfillment of our clients’ high-quality requirements and the responsibility for people and the environment have the highest priority for us. The fact that we meet the highest standards is not only proven by our satisfied clients but also by our numerous certificates.
Hydraulic pipe jacking is an innovative and environmentally friendly method for trenchless laying of reinforced concrete pipes. A wide variety of reinforced concrete pipes, both walkable and non-walkable cross-sections, can be installed to lengths up to 1,500m.
The following jacking procedures are standard practice for our highly motivated and well-trained construction teams:
- Pipe-jacking of non-walkable cross-sections using AVN technology
- • Pipe-jacking of walkable cross-sections in dimensions from ID1200 to ID3800 using the following techniques:
- Full face technology, mix and earth pressure balance (EPB) shields
- Partial cutting technique, hood shield
- with excavator/roadheader/auger
- with/without compressed air
decades we have been carrying out pinpointed tunneling work up to an outer diameter of
OD4700 on both straight and curved sections using the partial-face technology and cutting
edge surveying and control technologies. Using this method, any obstacle can be
dismantled and removed without problems in an open and freely accessible working area.
We are also able to detect metallic debris and explosive ordnance using the impulse neutron neutron procedure.
As an extension of our wide range of technical skills, we also use Horizontal Directional Drilling (HDD) for the precise installation of underground pipelines. The constantly evolving HDD technology enables the trenchless laying of pipes in almost any soil formation and depth.
Leak testing is mandatory for newly built systems according to DIN EN 1610. Leak testing is essential for environmental protection. Tightness is significant when dealing with dirty water, water-polluting substances and in water protection areas.
Our professional staff has decades of experience and extensive knowledge in carrying out leak tests on sewage pipes and sewers. We use two principal types of tests.
In our surveying department all matters relevant to surveying are professionally processed. Plausibility checks, feasibility studies, and permanent supervision of each construction site are essential for ensuring high-quality standards. To achieve the high accuracy required by our clients, precise measuring devices are used on construction sites. Our surveying electricians oversee the company’s surveying systems. Due to many years of experience using surveying systems in pipe jacking, the high demands of these complex systems can be ensured.
