## The Problem No Dig Service Solves

When a sewage or drainage pipe cracks, corrodes, collapses, or gets blocked, the traditional repair method requires digging up everything above it — floors, tiles, walls, gardens, even roads. This causes:
- Weeks of disruption
- Major structural damage to the surrounding property
- High reconstruction costs (tiles, plaster, flooring)
- Residents or businesses forced to vacate
- Roads and driveways torn up

No Dig Service eliminates all of that. Using trenchless technology, we repair the pipe from the inside. The surrounding structure is never touched.

# PART 2: SERVICES IN DETAIL

## Service 1: CIPP Lining — Εσωτερική Επένδυση Σωλήνα
URL: https://nodigservice.gr/pipe-lining

### What it is
CIPP stands for Cured-In-Place Pipe — the global standard for trenchless pipe rehabilitation. A spray nozzle is inserted into the damaged pipe and coats the interior walls with polyurethane resin. The resin cures within minutes, forming a smooth, watertight new pipe inside the old one. The old pipe becomes a structural casing for the new liner.

### How it works (step by step)
1. **CCTV Inspection & Cleaning** — A robotic camera surveys the pipe to map every fault. The pipe interior is thoroughly cleaned with mechanical brushes.
2. **Spray Nozzle Insertion** — A spray head with injection nozzles is inserted into the pipe from a single access point.
3. **Resin Application** — Polyurethane resin is uniformly sprayed onto the pipe walls as the nozzle travels through.
4. **Curing** — The resin hardens within minutes, forming a seamless, corrosion-resistant liner bonded to the pipe interior.
5. **Final Inspection** — A post-work CCTV check confirms full coverage. The client receives a before/after video report and written 10-year guarantee.

### Technical specifications
- Applicable pipe diameters: Ø40mm to Ø125mm
- Resin type: polyurethane (high-strength, chemical-resistant)
- Liner lifespan: 50+ years
- Curing time: minutes (polyurethane resin)
- Total completion: typically 1 day for residential
- Suitable for: straight sections, bends, T-junctions
- No need to vacate premises
- No wall, tile, or floor damage
- Immediately usable after cure
- Guarantee: 10 years written

### Best for
- Apartment buildings (main sewage stack)
- Houses with cracked underground drains
- Hotels and restaurants (no operational shutdown)
- Industrial pipes carrying chemical effluent
- Any structure where the surrounding area must not be damaged

## Service 2: Pipe Replacement — Αντικατάσταση Σωλήνα
URL: https://nodigservice.gr/pipe-replacement

### What it is
When a pipe is too severely collapsed, deformed, or disintegrated to be lined, it must be fully replaced. Pipe bursting replaces it without digging a trench. A hydraulic burst head is inserted into the old pipe, shatters it outward into the surrounding soil, and simultaneously pulls a new HDPE pipe into the void left behind.

### How it works
1. **Two access pits** — Only two small pits are dug at the start and end of the pipe section (vs a full-length trench in traditional replacement).
2. **Burst head insertion** — The hydraulic burst head enters the old pipe, attached to the new HDPE pipe behind it.
3. **Hydraulic pull** — Controlled force fractures the old pipe outward while placing the new HDPE pipe in position.
4. **Connection & Testing** — New pipe is connected at both ends, pressure-tested, and inspected by CCTV.

### Technical specifications
- New pipe material: HDPE (High-Density Polyethylene)
- HDPE lifespan: 100+ years
- Option to increase pipe diameter during replacement
- Only 2 access pits vs full-length excavation
- Suitable for: clay, concrete, cast iron, PVC
- Guarantee: 10 years

### Best for
- Pipes with complete collapse or major deformation
- Situations where larger pipe capacity is needed
- Municipal drainage under roads
- Pipes too damaged for CIPP lining

## Service 3: CCTV Pipe Inspection — Βιντεοσκόπηση Αγωγών
URL: https://nodigservice.gr/cctv-inspection

### What it is
A self-propelled robotic camera travels the full length of the pipe, recording every crack, offset joint, root intrusion, blockage, corrosion zone, or structural collapse in Full HD video with GPS-accurate positioning.

Pipe inspection is the diagnostic foundation of all pipe repair. You cannot reliably fix what you cannot see.

### What the report includes
- Full HD video of the pipe interior
- Timestamp-referenced photographs of each fault
- GPS distance from access point for each fault
- Recommended repair method per fault
- Before/after documentation for repair verification

### Technical specs
- Camera: pan-tilt-zoom, 360° rotation, Full HD
- GPS-referenced distance measurement
- Duration: 1–2 hours (residential), 3–8 hours (large networks)
- No excavation, no access pits required

### Best for
- Pre-repair diagnosis (mandatory before CIPP or pipe bursting)
- Preventive maintenance surveys
- Pre-purchase building inspections
- Post-repair verification (included in all CIPP/bursting jobs)
- Municipal network condition surveys

## Service 5: Pipe Cleaning & Unblocking — Καθαρισμός και Απόφραξη Σωληνώσεων
URL: https://nodigservice.gr/root-removal

### The problem
Blockages in pipes — whether from roots, sediment, grease, or foreign objects — cause recurring floods and drain failures. Simple cleaning cuts the blockage temporarily but doesn't address the underlying cause. The permanent solution is: (a) remove all blockage material, (b) seal the structural weakness (crack or joint) that allowed it to form.

### Our permanent solution
1. **CCTV survey** — map all blockage and fault points
2. **Mechanical cleaning** — specialized cutting and clearing tools remove blockages without damaging pipe walls
3. **Local CIPP liner** — after cleaning, each structural fault is sealed with a spot CIPP liner so the problem cannot recur
4. **Final CCTV verification** — confirm 100% clearance and sealed joints

### Guarantee
**5-year guarantee** on sealed fault points.

### Best for
- Root intrusion into pipe joints
- Recurring drain blockages
- Grease and sediment accumulation
- Any blockage where the root cause is a structural pipe fault

# PART 3: TECHNOLOGY EXPLAINED

URL: https://nodigservice.gr/technology

## Trenchless Technology: How It Works

### Polyurethane Resin (used in CIPP lining)
High-strength two-component polyurethane resin is applied via spray nozzle to the pipe interior. Once cured, it forms:
- A seamless, continuous coating bonded to the host pipe
- Smooth bore (improves flow vs original pipe)
- Chemical resistance to sewage gases and effluents
- Structural reinforcement of the host pipe walls
- Estimated lifespan: 50+ years

### CCTV Inspection Technology
HD robotic cameras provide GPS-referenced, 360° full-pipe documentation:
- Live video feed during inspection
- Timestamp-referenced fault photography
- Distance measurement from access point
- Enables precise, targeted repair (only fix what's broken)

### Thermal Imaging, Moisture Detection & Wall Scanning
Used to locate hidden moisture, leaks, and pipe routes behind walls and under floors without opening them. Identifies the source of damp patches and structural moisture before committing to any repair approach.

### HDPE Pipe Properties (for pipe bursting)
HDPE (High-Density Polyethylene) pipe — the gold standard replacement material:
- Completely smooth interior, no mineral deposits possible
- Flexible but structurally strong
- Resistant to all sewage chemicals
- Heat-fused leak-free joints
- Operating life: 100+ years
- Compliant with EN 13244 and ISO 4427
