Basement Construction is available from Dincel Construction Systems
Dincel Wall
The basement excavation for buildings is required for carparking, amenities and services.
The depth of the excavation, depending on the ground slopes can be single or multiple carparking/ storage levels.
Dincel Wall, available from Dincel Construction System, can be used:
In association with sheet piling with or without the presence of ground water which will offer the following advantages:
- The use of cold formed sheet piles, i.e. cheaper sheet piles
- Sheet piling without corrosion allowance, i.e. cost effective sheets
- Cheaper sheet piling can be sacrificed, hence eliminates the costs and risks for sheet extractions
- Much quicker sheet piling erection procedure since the water tightness of the sheet joints are not prime importance, as long as dewatering is manageable
In association with site excavations consisting battered ground conditions
- Elimination of sub-soil drainage and imported backfilling behind the basement Perimeter Dincel Wall
- Elimination of conventional footings where allowable ground bearing pressures are suitable
Note: The latest studies indicate that aggregate lines behind walls contribute to bacteria problems.
The sheet piles in association with Dincel are treated as temporary shoring purposes as they can be either removed or left in place to rust away. The supply of sheet piling is determined by its thickness and how well the joints of the sheet piling will retain the water.
The sheet piling suppliers in association with Dincel Wall do not need to consider the additional corrosion allowances for sheet thicknesses. Their sheet thicknesses can be determined by the drivability issue rather than corrosion.
However, drivability issues can be easily overcome by pre-drilling the ground where required. The joints of the sheet piling can be allowed to leak as long as the leakage is within the de-watering limits.
Today’s sheet piling technology is well advanced and reasonably stiff clays, even shale can be shored with the assistance of vibrationless hydraulic rams pushing into the soil, where required ground is pre-drilled to assist the drivability. Dincel Wall eliminates the need for sheet piling to be treated as permanent structural element hence reducing its relative costings and risks.
Dincel Wall provides a permanent water-proofed wall to water charged ground, is reliable and liability free, and a cost efficient rate.
