Many cities are faced with the task of renewing aging underground infrastructure. Many of these lines are beyond their useful life, but replacing them is a potentially expensive and disruptive task.

SEH can offer the knowledge and experience to incorporate trenchless technologies such as pipe bursting, horizontal directional drilling, and cured-in-place pipe rehabilitation in order to provide cost-effective solutions to your infrastructure needs.

Pipe Bursting
Pipe bursting is a process to replace sewer, water, or natural gas pipes by an using an expanding device to shatter damaged pipes and then draw in a replacement lines — all without digging the conventional trench.

Horizontal Directional Drilling
HDD boring minimizes environmental disruption by installing underground pipes and conduits along a surface bore path and is commonly used for installing telecommunications and power cable conduits, water lines, sewer lines, gas lines, oil lines, product pipelines, and environmental remediation casings. Because the method reduces impact to its surroundings, HDD is used to minimize traffic disruption and provide environmental safety for work with waterways, roadways, shore approaches, congested areas, and environmentally sensitive areas.

Cured-in-Place Pipe Rehabilitation
CIPP is a "pipe-within-a-pipe" process that repairs infiltration and leaks to pipes ranging from six to 96 inches by introducing a resin-saturated felt tube into a damaged pipe. The resin is cured by hot water or steam to form a jointless and corrosion-resistant replacement pipe, which is then inspected by closed-circuit TV.

Trenchless technology works well in tight spaces, and reduces:

• Traffic disruption
• Potential for erosion, weather delays, and liability
• Disturbances to existing utilities
• Restoration efforts and costs
• Environmental impacts
• Noise and air quality inconveniences
