Shoring & Excavation Support in Berlin and Brandenburg
Lula Bau GmbH plans and executes excavation support for construction projects in Berlin and Brandenburg. From a certain depth, shoring is required so that pits remain stable and neighbouring buildings are not endangered. DIN 4124 governs when and how. We select and execute the right method for every project.
At a Glance
From a vertical wall height of about 1.25 metres DIN 4124 requires the excavation to
be secured. Whether that becomes a slope or a shoring system depends on available space,
soil and neighbouring buildings rather than on price.
Slope or shore
| Slope | Shoring | |
|---|---|---|
| Space required | high, grows with depth | minimal, vertical wall |
| Cost | low | higher, but space-saving |
| Limit | slope angle per DIN 4124, depending on soil type | to be proven structurally |
| Typical | open site, surrounding region | inner city, adjacent buildings |
The permissible slope angle follows DIN 4124 by soil type. The value for your site comes
from the ground investigation report.
Which shoring method fits
| Constraint | Method | Why |
|---|---|---|
| Soil above groundwater, confined site | Berlin-type shoring | most economical, beams reusable |
| Excavation base in groundwater | sheet piling | interlocking profiles, watertight |
| Directly against existing buildings | bored pile wall | drilled rather than driven, no vibration |
| Loose, unstable soil | Essen-type shoring | secured layer by layer |
| Very deep excavation | bored pile wall with anchors | takes high earth pressure |
Where neighbouring buildings adjoin
Bracing or anchoring
| Bracing | Grouted anchors | |
|---|---|---|
| Principle | struts across the excavation | tendons into the ground behind the wall |
| Excavation | obstructed | stays clear |
| Neighbouring plot | not affected | usually affected |
Berlin ground conditions
Berlin sits largely on sand, which is not cohesive, and the groundwater table is high in
places. That is why watertight shoring is more common here than elsewhere and why
dewatering is a cost block of its own. Lowering groundwater requires a water permit.
Together with excavation and demolition
Shoring and earthworks interlock: digging proceeds layer by layer
while the infill wall grows with it. If a building still stands on the site, we also
handle demolition.

FAQ
Frequently Asked Questions
When is shoring mandatory?
Under DIN 4124, vertical excavation walls must be shored from a depth of about 1.25 m unless a sufficiently flat slope is possible. With tight surroundings or groundwater, shoring is almost always required.
Is the shoring removed after construction?
Usually yes. Once the structure is complete the boards and beams are pulled and reused where undamaged, which noticeably reduces the cost. If the shoring stays in the ground, for instance because pulling it would cause settlement next door, it is called lost shoring, which is more expensive and should be settled before work begins.
Which shoring method is right?
Above groundwater, Berlin-type shoring is usually the most economical solution. In groundwater or for very deep pits, sheet piling or bored pile walls are used. Next to existing buildings, low-vibration bored pile walls are advantageous.
What is the difference between Berlin-type and Essen-type shoring?
With Berlin-type shoring, vertical steel beams are set and lagged after excavation, which requires temporarily stable soil. With Essen-type shoring, horizontal lagging is installed layer by layer with the excavation, suitable for low-stability granular soils where a free-standing cut is not possible. We decide based on the soil survey.
