Industries
Keep the line covered, supported and in service.
Creeks, rivers and drainage areas can move long after a pipeline is installed. When cover is lost or banks retreat, pipelines can be exposed to vehicles, vandalism and, in some cases, loads they were never designed to withstand.
Start a ConversationCover has washed out and the pipeline is visible in the bed or banks of a water crossing.
Bed degradation and scour at the crossing, often set off by changes upstream or downstream that lower the channel.
We investigate the crossing and trace the cause, then engineer and permit protection that restores cover and holds the bed in place.
The designed span in a ravine has eroded because the ground beneath it has washed away and the span needs mechanical support.
An engineered crossing that calls for support, or flow that has removed material beneath the line faster than the channel can rebuild it.
We engineer and install support under the span and, where erosion created the condition, stabilize the surrounding site.
The outside bend is eroding and endangering the nearby pipeline.
High-velocity flow concentrated against the bank as the channel migrates.
We model how the river is behaving and redirect the flow away from the bank, armoring it where the river leaves no room to recover.
A step or drop in the channel bed is working its way upstream toward the pipeline crossing.
A lowered channel downstream. Every flow event pushes the drop further upstream.
We engineer grade control that stops the knickpoint where it is and stabilizes the channel through the crossing.
In the field
Before
AfterMeandering creeks see changing water levels and flow rates, and they can expose a pipeline quickly. We rebuilt this bank as a stepped wall over the line.
Before
AfterOver time, erosion can leave a pipeline spanning a ravine it was never meant to cross. That calls for prompt work: support beneath the pipeline and armoring around it.
Before
AfterA headcut was cutting its way upstream through open ground, taking more land with every storm. We installed stepped grade control to stop the knickpoint and step the water down safely to the channel below.
Before
AfterFlow through this road crossing had cut the bank beside it back toward the road. We rebuilt the bank and armored it where the flow leaves the crossing.
Before
AfterBelow a roadway, runoff cut this drainage channel deep into red clay and exposed the line running through it. We rebuilt it as a lined channel, from the road culvert down, that holds its grade.
Before
AfterDebris and high flows scoured this creek crossing until the line beneath it was exposed. We restored the cover and rebuilt the crossing over new culverts.
Before
AfterThe river was taking this bank, and the farmland above it, with every high water event. Five years after the work, the bank is rebuilt and green.
Before
AfterRunoff at this processing plant had carved the drainage under the pipe racks into open ditches. We lined the channel to protect the ground the supports stand on and mitigate sediment flow.
Before
AfterWhen a river starts cutting toward a transmission line, the structures beside it are next. We armored the banks and channels to protect the utility infrastructure.
How we work
Whatever the industry, every project follows the same six steps, and our own people carry it through each one. Nothing is handed off to another firm along the way.
