Driveway Tunnel For Fry Foods
Quick and efficient was the name of the game as we took on a recent job for Bloc Contractors, pulling 3 x 110 diameter pipes and 1 x 160 diameter pipes a short distance under the concrete entranceway of the Fry Foods factory.
This doesn’t mean it was an easy job, not when our rig was hanging over the edge of a retained hill with little to no wriggle room!
Fibre Tunnelling Under the R102 – Verulam
In a fibre installation project for MTelecoms, the Rolkon team focused on length and location as they drilled under the R102 in Verulam.
Given the tight location on the edge of the busy R102 and the 67m drill under the road, the focus was on getting the set-up and navigation scanning just right. The steady focus resulted in a 2-hour pilot drill, with another hour required to pull the pipe back.
Fibre Tunnelling For MTelecoms – New Germany
What a job this has been! 3 months of drilling and moling for MTelecoms who is laying fibre in a residential area in New Germany.
1100 metres drilled and 1800 metres of moling as we passed 450 houses with some tricky tunnelling and site conditions.
Part of our approach to resolving each site is ensuring we foster long-term relationships with our clients and thanks to the Rolkon team for extending working hours to get this job done, we will soon be starting a new project with MTelecoms that we are excited to get working on.
Edendale Sewer Sleeve – Pietermaritzburg
Railway lines, vegetable gardens and tight community living Rolkon faced a tricky drill site during a 2-day project in Edendale in PMB for Bloc Construction.
Before the new sewer sleeve could be installed the live line had to be decommissioned and securely blocked off, after which the pilot drill of 50m was done making sure the grade was appropriate for the sewer flow. Once the 12m sleeve was installed the sewer line was recommissioned.
As is the Rolkon way – the site was successfully resolved, with cabbages and railway line left undisturbed!
Anton Lembede Aqueduct – Durban Inner City
This job in the inner city of Durban involved horizontal drilling under an existing stormwater culvert in order to pull an 800mm sleeve with a product pipe weighing 11 tonnes in total.
The site situation required that the pilot be drilled from 80m away with the hole 4m below ground. At this depth, the hole was below sea level which meant managing the tidal water flow into the hole. The pipe was pulled a total of 18m and the project took 2 days to complete.
M13 Fields Hill Crossing – Durban
This roadside project required us to horizontally drill under the M13 highway without causing any disruption to traffic. A difficult site to access for both machinery and the technical team, we had to target drill because the high traffic volumes did not allow us to navigate across the road.
A job turned down by another drilling company, difficult soil conditions and the length of the drill itself added to the challenges. But as we do at Rolkon, we got the job done, living up to our promise of leaving no site unresolved!
