Uretek India:::. Uretek for Railways .

Uretek's patented ground improvement techniques are used worldwide to quickly compress or recompress soil.

Uretek applies its Deep Injection and Powerpile™ technologies to improve the bearing capacity of soils which underlie permanent way.

The Uretek Method is fast and can be applied while rail traffic is on the move, ensuring no downtime. In many cases, jobs that take weeks using other methods can be completed using the Uretek Method in just hours.

Our work is completed under the guidance of a Geotechnical Engineer under conditions of full International Quality Assurance.

	Uretek relevels trackwork and rail bridges. Piers can be re-substantiated, and all this can be done between train operations. Uretek can work during down times and in confined spaces. Our equipment is portable, so where there are no roads, our workshop can be mounted on a flat wagon and taken by train to the worksite.
Embedded Rail. Embedded rail is very diffucult to re-level, whether it be found in level crossings, tramways or on docks. Uretek solves the problem fast. Our expanding resins are injected under the track base, stabising and strengthening soil, and lifting track back to level. All this is done while rail and vehicular traffic continues to operate through the worksite.
	Re-level Track & Small Bridges. Bridges with non-piled footings which fall out of level due to soil weakness, respond quickly to the Uretek Method. Locations which would be difficult to reach by road are no problem for Uretek- we load our fully integrated workshop onto a container wagon and train it to the site! The bridge at left was re-leveled in just two days, and rail traffic flow was not interputed. Our work resulted in the local rail speed limit being raised from 20 KPH to 100 KPH.
New Powerpiles – Perfect for Embankments. Strengthen soil in specific areas Support track in narrow locations Fast soil strengthening in busy times Strengthen embankments without re-construction No line downtime

Uretek - The Box Section and Viaduct Specialists.

Re-levelling Box Sections.

Box sections sink because the ground underneath is not strong enough to hold them. Sometimes the ground’s bearing pressure was never calculated correctly, sometimes the nature of the ground changes due to water incursion, and sometimes more weight is placed on the culvert than engineers originally calculated.

Whatever the cause, Uretek’s patented system regularly lifts culverts into place after improving bearing pressures sometimes by 400 or even 500%! N values are up, bearing pressure is up, the culvert is no longer down!

The Uretek Method can even help when a culvert has dropped as far as the culverts at right. Even a drop of 300mm is no problem for Uretek!

Undersealing Box Sections.

Above: Uretek underseals culverts and ensures that water fows through the culvert - not under it.

Correcting Bridge Piers.

			This bridge on the main Sydney - Melbourne railway line had a pier that was loose. The steel beams sitting on the pier were in danger of fracturing. Uretek was able to strengthen the soil under the pier and lift the pier back into place. In fact Uretek is so strong, we were able to not just lift the pier, but in tests conducted after, Uretek lifted the pier, bridge and a 110 tonne loco 9mm!
		Platform re-levelling
		Railway platforms that are out of level present trip hazards to clients, can result in people falling on to tracks and jostle goods and people. Uretek re-levels platforms, such as this one in Cloncurry Qld, to provide greater comfort and safety, and to help ensure that goods arrive in pristine condition.
		Uretek - Fast Soil Compaction in Confined Spaces
			Because Uretek's workshop is so portable, Uretek works just as easily in tunnels and pipes as it does in the open. And, as with all Uretek work, even in these difficult locations, we are able to do our work with a minimum of interference to operations.
