Introduction

Sliplining is Hinterland Group’s in‑house trenchless method for restoring deteriorated pipelines by inserting a new carrier pipe into the existing host and grouting the annulus to create a long‑life structural solution—all with minimal surface disruption. It complements our full PRIME stack (Pipeline Rehabilitation, Repair/Replacement, Inspection, Maintenance, Evaluation/Assessment) delivered across the Southeast since 2006. See service overviews on our Services and Pipe Rehabilitation pages.

Georgia use cases we solve with sliplining

Aging gravity sewers and storm drains with cracks, offsets, or infiltration where open‑cut replacement would disrupt streetscapes and sensitive areas. Relevant statewide context appears in our Georgia CIPP page (historic districts, coastal conditions, clay soils).
Undersized culverts and drainage crossings where a new carrier pipe can be inserted and annularly grouted to restore capacity and reliability with limited traffic disruption. See method mix on Pipe Rehabilitation.
Industrial/process piping where shutdown windows are tight and trenchless staging reduces downtime; learn about our industrial readiness and 24/7 response on Industrial.
Post‑storm recovery and resilience upgrades following severe weather events affecting Georgia; for our regional disaster response capabilities, see Hurricane Helene recovery support.

How Hinterland delivers sliplining projects

Assessment and planning: condition data via CCTV inspection after pre‑cleaning; risk and alternatives documented through Evaluation & Assessment.
Bypass and continuity: in‑house design, setup, and operation of bypass systems to maintain service continuity, per our Repair & Replacement capabilities.
Carrier pipe selection and design: material, OD/ID, and annular grout design chosen for structural performance and hydraulics; approach detailed under Pipe Rehabilitation.
Installation: staging, insertion/pulling, spacers/centralizers as required, annular grouting, end seals, reconnection of laterals/structures, testing, and documentation.
Handover and lifecycle support: preventive Maintenance plans to protect asset life and verify performance.

Why municipalities and owners in Georgia choose Hinterland Group

Full trenchless toolbox, performed in‑house: sliplining, CIPP, pipe bursting, and geopolymer spincast, enabling unbiased method selection. See Pipe Rehabilitation.
Rapid statewide mobilization: 24/7 emergency response with 15‑minute callback and Southeast coverage, supported by our Morganton, NC wetout facility and Georgia‑focused deployments on CIPP – Georgia and storm response pages. Emergency services overview: Maintenance (Emergency).
Safety culture: dedicated safety leadership with OSHA‑certified personnel and rigorous protocols. Learn more on About.
Proven across markets: cities, counties, property managers, industrial sites, airports—see Markets We Serve.

Sliplining vs. other trenchless options (selection guide)

Scenario in Georgia	Sliplining	CIPP	Pipe Bursting
Host pipe badly deformed or missing sections	Strong fit (new carrier pipe provides structure)	Limited, depends on ovality/voids	Strong (full replacement)
Maximize hydraulic capacity	Neutral to reduced ID (depends on carrier)	Maintains near‑host ID	Strong (upsizing feasible)
Sensitive surface areas (historic streets, campuses)	Strong	Strong	Strong
Numerous service laterals to reinstate	Moderate complexity	Strong (robotic reinstatement)	Moderate (new main + reconnections)
Severe soil movement or grade issues	Moderate	Moderate	Strong (new alignment/grade possible)
See method capabilities at Services and Pipe Rehabilitation.

Georgia coverage and mobilization

Service area: statewide Georgia—urban cores, suburbs, coastal communities, and rural corridors. Regional coverage detailed on Markets We Serve and CIPP – Georgia.
Response: 24/7 with 15‑minute callback for emergencies and rapid deployment; see Maintenance (Emergency).

Procurement and delivery

Contracting: continuing services contracts, task orders, and competitively bid capital projects. Portfolio examples appear in Case Studies.
Turnkey delivery: assessment, design‑assist, traffic control coordination, bypass, slipline install, restoration, QA/QC, and long‑term maintenance.

Frequently asked questions

Can you keep flow during construction? Yes—our teams design and run in‑house bypass systems to maintain service, per Repair & Replacement.
How do you minimize disruption in historic districts? We stage trenchless access pits and coordinate tightly with stakeholders; see our Georgia‑specific trenchless approach on CIPP – Georgia.
What if inspection shows a better method than sliplining? Because we perform all trenchless methods in‑house, we recommend the best‑fit approach (CIPP, bursting, geopolymer) per Pipe Rehabilitation.
Do you offer ongoing maintenance? Yes—scheduled cleaning, inspection, and repair via Maintenance.
