Cause for WG 100:- Increasing demand for high-density development- Maximum utilisation of ground area results in deeper
excavations in crowded cities- Strong impact on high value surroundings
Our Intention:- Overview about different types of excavations- Relevant elements of such construct- Underwriting recommendations

is not afraid of water
is an Idiot! »Wolfgang Bartsch

Mnemonic

Small problem, huge impact!
Wetted surface of a pit (without ground area)
H=5m
B=30mL=40m
Wetted surface: 2 x 5 x (30+40) = 700 sqmLeakage estimated 0.5 sqm < 0.1%
Mnemonic
05.10.2016WG100 22
The fatal chain:Water flow – velocity – inner erosion of soil –first fine particles are washed out, then sand andgravel -this results in an increasing watervolume and thisin return in an increasing capacity for soil-transport
It’s a non healing automatic self-accelerating process!
Mnemonic
