Weyburn– Contain Enviro Services had some shiny secondary containment components in its booth at the Saskatchewan Oil and Gas Show June 3-4.
Bill Moore works out of Calgary while Glenn Eckert works out Edmonton. Both work in business development. They detailed what was in the display.
Secondary containment is their bread and butter business. The company is based in Grande Prairie.
“We supply and install product,” said Moore.
They noted a recent positive meeting with a significant local oil producer, he noted.
For primary containment the company has its Geomembrane line. This product is used to line ponds and pits. Examples include produced water storage areas and landfills.
Rainwater collection ponds are another application for primary containment.
Plant sites include facilities and tank farms.
For secondary containment, Moore spoke of their 15-gauge corrugated steel product that is manufactured by Westeel. It’s galvanized with zinc coating.
“We do all the prefabrication in Cold Lake and Grand Prairie,” Moore said.
It’s the same steel used for grain bins, he noted. That makes sense as Westeel is a major grain bin manufacturer for the agricultural sector.
They also provide crossover ladders and stairs.
Contain’s product is suited for plant sites with durations of six months or greater. It can be added like Lego blocks, Moore said.
“It’s expandable, a modular system.”
The flexibility built into the system includes radius panels and straight sections. “We can accommodate any size or shape,” he noted.
“Our panels overlap and have a flush face. We have a basemount liner.”
By mounting the liner near the bottom of the sidewalls, less of the liner is exposed to ultraviolet rays which can cause deterioration. It’s typical to cover the liner with a layer of gravel.
“We put a backfill layer over our Geomembrane,” Moore said.
All the fasteners have rubber gaskets, ensuring a liquid-tight seal.
“It’s common to us, but not others. Others are not leak-proof,” he said.
Contain Enviro can provide frac tank liners as well, Eckert said.
A patented product they carry is the SD Boot, settlement detection boots.
They look like the rubber housing on a CV boot on a front-wheel-drive car, except instead of going over an axel, they go over a pile. The ribbed portion allows the boot to stretch. The top part of the boot is attached to the pile. The bottom part is attached to the liner. This allows for expansion according to ground movement.
“If there’s settlement onsite we can handle up to 16 inches of settlement,” Eckert said.
The boot is welded to the Geomembrane.
This product is especially useful in areas of muskeg, they noted. “We use it on all our sites,” Eckert said.
