CIPP Lining

Safe, sturdy, and long-lasting, cured-in-place-pipe (CIPP) is at the heart of SAK’s sanitary and stormwater pipeline rehabilitation processes.
Large Diameter Sliplining

Install new pipeline within your old infrastructure. Sliplining delivers the performance of new pipeline with minimal digging and disruption in difficult to access locations.
Large Diameter Tunneling

When your situation calls for complex pipeline expansion or simple repair, trust SAK to expertly excavate tunnels from 4-foot diameter to 32-foot arch-shaped tunnels in all kinds of ground conditions.
Shaft Excavation
Shotcreting

One of the most versatile tools in SAK’s arsenal of underground construction solutions, shotcreting plays a vital role in a variety of projects. Shotcreting is a versatile tool for strengthening structures in tunnel construction, pipeline rehabilitation, soil stabilization, and culvert repair
Spiral Wound PVC (SPR)

SPR is a spiral, machine-wound, trenchless pipe renewal process that renews 18" to 144" circular, box culvert, arched, and other non-round pipeline applications. Often, SPR can be installed in live flow conditions.

Stormwater

Prepare your infrastructure for whatever Mother Nature has in store.

Broken roads, flooded streets, polluted waterways, scrambled traffic—the problems brought by aging stormwater infrastructure are testing community resources and public patience. Pipelines constructed a century ago to handle both sewage and stormwater are proving inadequate for either task today. And even more recently built systems struggle under the stresses of overuse, community growth, and extreme weather patterns.

Facing strict regulations and hefty fines, municipalities seek effective new solutions. SAK delivers with a range of stormwater pipeline renewal technologies. At the heart is our industry cornerstone CIPP process, using industry leading “pipe-within-a-pipe” technology to renew existing systems from the inside. In addition, newer state-of-the-art processes, such as Spiral Wound PVC (SPR), gives you solutions to tackle pipes and culverts of odd shapes and/or up to 144 inches in diameter. Both these processes provide a number of advantages over traditional dig-and-replace methods:

Efficient: Our trenchless technology allows us to rehabilitate pipes from above ground, with minimal disruption to traffic flow or existing landscape, roads or structures.
Customized: Rehabilitate rather than dig-and-replace traditionally difficult large, odd-shaped storm sewers.
Strong: Strengthen deteriorating pipelines instead of replacing them—CIPP and SPR restore structural integrity and flow to the host pipe, renewing your stormwater system for another 100+ years of reliable service.
Affordable: Costing less and causing less disruption than traditional open-cut methods, no-dig solutions can lower treatment and pumping costs and can reduce the need for ongoing maintenance.

You can’t prevent storms. But you can prepare for them. SAK helps cash-strapped communities rehabilitate deteriorating stormwater systems for up to 40% less than dig-and-replace methods.
