Projects completed by Solvocore
We will be listing all of Solvocore’s completed projects below. Make sure to check regularly for updates.
Bridge Pier Head
Rehabilitation –
After years of use, these pier heads at one of Transnet’s bridges in Brits started to show signs of cracks and strain.
The pier heads needed to be core drilled and reinforced with Dywidag bars, which were grouted into position; then dowel bars were drilled and epoxied and rebar was fixed into position.
Light weight timber form work had to be manufactured and erected, due to access restrictions.
Wall Sawing
This 35m long x 6m tall Reinforced Concrete Wall had to be removed by using our Wall Sawing System.
A tower crane with 8-ton lifting capacity was available on site. The maximum block sizes that the crane could lift were determined and marked, lifting holes were core drilled for the slings, followed by the cutting and removal of the concrete panels.
Concrete Column
Rehabilitation –
These 53m high concrete columns showed signs of cracks and spalling. After the severity of these defects were identified and quantified by the client, we assisted with the Method Statement and Quality Control Plan on how to repair the defects.
After approval by the client, we then started with the repairs. Lifting Booms that can reach up to the 53m height level were used to access the different defects to carry out the spalling repair and crack repairs.
Dam Spillway
– Diamond Wire Cutting
Solvocore had to assist with the cutting of an existing concrete spillway at Kudube Dam in Hammanskraal.
The existing Water Purification Plant was upgraded and therefore the plant needed more “inflow volume” from the dam. This was done by cutting an additional slot into the existing spillway to increase the volume. The activities included installing and sealing a cashion behind the concrete spillway, core drilling 50mm diameter up to 7m deep horizontally, feeding diamond wire through the holes and cutting the spillway into sections. Lifting brackets needed to be installed with epoxy to allow the 250 ton crane to remove the sections of concrete.
Concrete Floor Grinding & Repair
The client was not satisfied with the existing concrete floor finish in an existing warehouse. Solvocore was asked to assist with improving the finish of the floor, as well as repair the cracks and indentations in the floor.
This was done by grinding the floor to a smooth level surface with a floor grinder, and then repairing the indentations with approved patch repair mortar and sealing the cracks in the slab.
Silo Strengthening
Solvocore was asked to assist with the strengthening of a silo on an existing mine.
This is being done by constructing 10No additional concrete rings around the circumference of the silo at every 2m level.
This work includes:
- Scanning the concrete to identify existing reinforcing.
- Scabbling the surface of the silo circumference to expose the aggregate
- Drilling holes at every 200mm C/C top and bottom
- Installing reinforcing dowels
- Doing pull-out tests on each dowel to ensure it meets the design requirements
- Bending the reinforcing to allow for rebar fixing
- Supply and installation of flexible waterproofing bandage between the silo walls and the concrete rings
