Introduction

Sliplining is a trenchless rehabilitation method that restores aging water, wastewater, and stormwater pipelines by installing a new carrier pipe inside the existing host pipe, then grouting the annular space to reestablish structural integrity and extend service life. Hinterland Group performs sliplining alongside other trenchless methods across Florida for municipal and private clients, integrating inspection, bypass pumping, and restoration into a single, in‑house delivery. See our trenchless services overview and sliplining offering on the Services and Pipe Rehabilitation pages. Services, Pipe Rehabilitation.

Where we operate in Florida

Headquartered in Riviera Beach, Hinterland Group serves communities throughout Florida with pipeline rehabilitation, utility construction, and emergency response. We support cities, counties, utilities, property managers, industrial facilities, and contractors statewide. About, Markets We Serve, Contact Us.

What sliplining solves

• Structural deterioration of gravity sewers, storm drains, and culverts without extensive excavation.

• Infiltration/exfiltration through joints and cracks that drives unnecessary treatment costs and environmental risk.

• Localized defects and moderate ovality where a continuous carrier pipe can bridge and stabilize the host.

• Projects in sensitive, congested, or coastal areas (common in Florida) where open‑cut replacement is disruptive or impractical.

How sliplining works (step‑by‑step)

1) Inspect and clean: Crews perform vactor cleaning and high‑resolution CCTV inspection to verify condition, alignment, and obstructions. Inspection 2) Bypass and access: Where needed, we engineer and operate in‑house bypass systems to maintain service and prevent SSOs during construction. Repair & Replacement (Bypass) 3) Insert carrier pipe: A new pipe is inserted into the host via existing structures or limited pits, minimizing surface disruption. 4) Grout annulus: Low‑shrink, strength‑specified grout fills the annular space, providing composite structural action. 5) Reconnect services and structures: Laterals, manholes, end treatments, and appurtenances are restored; final CCTV verifies quality. Inspection 6) Restore surface: Pavement, curb, walks, and landscaping are repaired per agency standards.

Method selection: sliplining vs. other trenchless options

Method	When it fits	Key advantage	Considerations
Sliplining	Host pipe is largely continuous; access for insertion is feasible	Durable structural renewal with minimal excavation	Reduces internal diameter; capacity impacts must be evaluated
CIPP lining	Host pipe is continuous with limited intrusion and bends	Jointless, smooth, minimal diameter loss	Requires curing logistics and access; resin selection matters
Pipe bursting	Upsizing or severe host failure where replacement is preferred	New pipe with possible larger diameter	Requires space for pull and careful utility coordination

These methods are all performed in‑house by Hinterland Group, allowing objective, project‑specific recommendations. Pipe Rehabilitation, Services.

Florida‑specific design and construction notes

• High groundwater and coastal conditions: Construction means/methods account for buoyancy, inflow, and corrosion common to Florida’s high water table and coastal environments. Repair & Replacement

• Traffic and urban constraints: Trenchless access minimizes lane closures and business disruption in dense corridors; restoration is localized. Portfolio

• Stormwater and culverts: Sliplining is well‑suited for large‑diameter storm drains and culverts where environmental and access constraints limit open‑cut.

Frequently asked questions

• Will sliplining reduce capacity? Sliplining adds a structural carrier pipe, which reduces inside diameter; capacity impacts are evaluated during design and mitigated where necessary through hydraulic review and method selection.

• Can sliplining be used under roads and rail? Yes. Because it is trenchless, most work occurs from access points, limiting surface disturbance and restoration.

• What pipelines can be addressed? Sliplining commonly rehabilitates gravity sewers, storm drains, and culverts; pressure applications are evaluated case‑by‑case.

• Do you provide maintenance after construction? Yes. We offer scheduled cleaning, inspection, and condition assessment programs to protect the investment. Maintenance
