Micro Piles
|
|
|
The basic concept of piling works, is to transfer the loads of the construction through upper weak soil layers to more competent deeper soil layers
|
Due to the small diameter of micro-piles, they can only sustain the loads applied to them by the skin friction interaction between their surface area and the surrounding soil layers.
|
To improve such friction interaction, skin grouting is performed around the pile shaft at the depth of
penetration of the pile through the bearing strata.
|
The soil adjacent to / surrounding the pile shaft is grouted by cement mortar to cover a pre-determined length by using tube-a-manchette method, or though grouting pipes attached to the
reinforcement cage of the micro pile as in
