Shotcrete - Gas Vapour Intrusion Protection Pt2

This is the 2nd photo of a 3 part series in which RIX completes a project to rehabilitate a site that previously contained a service station. The soil is severely contaminated with Hydrocarbons. RIX partnered with our client in designing a solution that employed shotcrete and a gas vapour membrane to protect end users from toxic gases contained in the contaminated soil.

The first application of shotcrete seen in part 1 of this series has now had the membrane painted on and the steel added in preparation for the final layer of shotcrete to complete the protective shotcrete sandwich.

Shotcrete - Gas Vapour Intrusion Protection Pt1

RIX recently took part in a project to rehabilitate a site that previously contained a service station. This site presented some interesting challenges as the soil was severely contaminated with Hydrocarbons. RIX partnered with the client in designing a solution that employed shotcrete and a gas vapour membrane to protect end users of the structure from any intrusion of toxic gases contained in the contaminated soil.

Seen here in this picture is the smooth (trowel finish) blinding layer of shotcrete. The gas vapour membrane will be applied to this smooth shotcrete surface and then sandwiched between the final layer of shotcrete which will form the walls of the underground carpark.

RIX Install New Guard Rail Design Pt1

RIX have been invited by a Local City Council to install an innovative new Road Guardrail System. Recently a truck crashed into the Guardrailing severely damaging approximately 50m of rail. This has left passing traffic unprotected from the 20m drop into the water of the bay below.
In the video you can see our specially designed excavator mounted drill mast, drilling the 65mm diameter holes through the rail and back under the road. The 24mm x 3m rockbolts will be installed through the custom built Double Posts of the Guardrail and grouted into the drill holes. The bolts have been designed to provide the posts with support in the incompetent ground, present onsite. It is important to note that the rock bolts have been fabricated with ductile steel as opposed to high tensile steel, this is to combat shock loading which will inevitably occur in the event of another vehicle hitting the rail.

RIX Design & Build Custom Rock Drilling Rig Pt1

RIX were recently invited by our Client to complete works on the Jindabyne Dam Spillway. The project is part of the "Water For Rivers Program", which will restore environmental flows to the water starved Snowy River. The river originates from a height of 2.2km on the slopes of Mount Kosciuszko, Australia's highest mainland peak, draining the eastern slopes of the Snowy Mountains in New South Wales, before flowing through the Snowy River National Park in Victoria and emptying into Bass Strait 350km later.

RIX originally began works on the spillway in 2004 and were happy to return to install the final rockbolts and shotcrete.
Seen here is RIX's custom engineered Drilling Basket. This enabled us to drill the 100mm diameter,12m deep rockbolts into the granite surrounding the Spillway.
