The Earth's bearing capacity must provide the required uniformity of support prior to the commencement of building works. This is where M.J. Eriksson’s Foundation department will investigate the in-situ soil conditions in order to determine the optimal methods and procedures to suit the actual site conditions.
Before the civil work can commence, the geotechnical data has to be carefully analyzed in order to determine the subsurface bearing capacity, sustainability and risk of settlement. An extensive investigation in relation to the environmental conditions will also be carried out accordingly.
Prior to commencement of roads & rail works, quays and harbor constructions, dredging and reclamation works, it may be required to carry out sheet piling, earth anchoring, pile driving or drilled foundations.
All of this work is carried out with the latest machinery and in the methods that meets the highest Environmental requirements for vibration and noise.
Where direct foundation is not possible, it is advantageous to use framed reinforced concrete / steel piles. Pile ramming is executed at terrain ground level in required length, and with dimensions of 200x200mm to 450x450 mm.
Drilled foundation is an alternative method to driven piles. This method is utilized to avoid excessive vibrations in sensitive areas. Is the earth very sandy or in groundwater level, we will use casing to avoid collapse.
Sheet piling is usually performed in projects associated with water, bridge or berth structures. The sheet piling sizes and profiles are available in almost unlimited variations, governed by the earth's bearing capacity, which determines the piling depth.
We can put the sheet piling through very hard soil layers with hammering, causing noise and vibrations, which can be reduced utilizing a piling vibrator, where the noise and the shaking of the ground is limited, for example executing works in the densely populated areas.
M.J. Eriksson also conducts sheet piling for temporary measures by stabilizing the surrounding areas associated with deep excavations near roads, cable trenches utilizing HEB profiles filled with timber, steel sheets or sprayed concrete that holds the underlying terrain in place.
