PP Geotextile Construction Plan for Ground Stabilization and Drainage Systems

I. Project Overview

The [Project Name] at [Location] involves construction in [Specific Area]. Due to complex geological conditions, high groundwater levels, and soil stability concerns, PP (polypropylene) geotextiles will be deployed for reinforcement, drainage, and separation to ensure long-term structural integrity.

II. Material Specifications

Geotextile Selection

• Material: PP geotextile compliant with national standards.

• Key Parameters:

• Mass per unit area: [X] g/m²

• Tensile strength: ≥[X] kN/m (longitudinal), ≥[X] kN/m (transverse)

• Tear resistance: ≥[X] N (both directions)

• CBR puncture strength: ≥[X] kN

• Permeability coefficient: [X]×10⁻¹ to [X]×10⁻³ cm/s

Inspection & Storage

• Verify certifications (quality reports, factory test data). Conduct batch sampling.

• Store in ventilated, dry areas; avoid UV exposure, chemicals, and open flames.

III. Construction Methodology

Subgrade Preparation

• Clear vegetation, debris, and loose soil. Achieve surface flatness (±[X] cm).

• Fill depressions with compatible material; grind sharp rock protrusions.

Survey & Layout

• Mark boundaries using total stations (control points ≤[X] m apart).

• Align geotextile with flow direction (flat areas) or top-to-bottom (slopes).

Installation

• Unrolling: Lay without tension; maintain ≥[X] cm overlaps.

• Seaming:

• Sewn joints: Industrial sewing machines (stitch spacing: [X] mm; thread strength ≥ geotextile).

• Bonded joints: Apply adhesive evenly (width ≥ overlap); roll to eliminate air pockets.

Anchoring

• Slope crest: Bury in [X] cm × [X] cm trench; backfill compacted soil.

• Slope face: Secure with U-pins (spacing: [X] m; length ≥[X] cm).

• Flat areas: Cover with [X] cm sand layer or weighted mats.

QC & Repair

• Inspect for wrinkles (≤50 mm), gaps, or loose seams.

• Patch damages with [X] cm oversized patches (sewn/bonded).

• Test samples (strength, permeability) per [X] m².

IV. Schedule

Note: Adjust for weather delays; suspend work during heavy rain/storms.

V. Quality Assurance

• QMS: Project manager-led team; process controls from procurement to handover.

• Process Checks: Validate each step before proceeding (e.g., seam strength).

• Material QC: Reject non-compliant batches; prevent storage degradation.

• Training: Regular upskilling on installation standards and defect mitigation.

VI. Safety Protocols

• HSE Team: Dedicated safety officers; daily toolbox talks.

• PPE: Mandatory helmets, harnesses, and non-slip footwear.

• Equipment: Certified operators; pre-use inspections.

• Emergency Prep: Fire/collapse drills; onsite first-aid kits.

Key Technical Standards

• Overlap width: ≥300 mm

• Slope pin spacing: ≤1.5 m

• Patch overlap: ≥150 mm beyond damage

Note: Replace [X] with project-specific values. Adapt anchoring/seaming methods for site conditions.
