Bank Repair | MRF Plant Hire

A valued client reached out to MRF Contracting for assistance with a repair project on a water main near a stream. They expressed concerns about the valve's proximity to the water table, which was within 2 meters of the stream bank. MRF Contracting was entrusted with the responsibility of safeguarding the stream from potential silt intrusion during the excavation process.

Following the completion of the project, we implemented Gabion baskets to shield the bank from erosion. We then reinstated the subsoil to its original depth, followed by topsoiling to its original height. This topsoil was seeded, and to prevent runoff, a coir mat was applied on the bank.

Valves and the Vegetation

Here you can see the stream, the proximity of the valves and the vegetation on the stream bank

Eliminating the trees

Our teams initiated the project by clearing the bank of vegetation and eliminating the trees.

Asses the site

Once the vegetation was cleared our client could properly asses the site.

Encroachment

The valve is situated beneath the water table, and excavating down to this level would result in encroachment upon the stream.

Materials

(after creating a plan) we delivered materials to the site.

Flumes and dams

Our teams installed temporary flumes and dams then proceeded to pump the water from outside the designated working area.

Drained

In this image, you can observe that the water has been drained, leaving the working area dry.
