General installationKeep it intact
Keep it intact
until covered.
Follow the project method statement and current manufacturer guidance. The steps below are useful principles, not a substitute for application-specific design or inspection.
Store and protect
Keep rolls securely stacked and wrapped until required. Protect the fabric from damage and unnecessary exposure.
Prepare the subgrade
Remove shrubs, large rocks and similar obstructions. Fill deep ruts, voids and depressions to provide a smooth support.
Roll out to the contours
Keep the textile taut enough to minimise folds, but do not stretch it so that it bridges hollows. Temporary ballast may be needed in wind.
Maintain continuity
General manufacturer guidance is at least 300 mm overlap side by side and 600 mm end to end. Increase overlaps on soft or uneven ground.
Place cover fill safely
Do not traffic directly on exposed geotextile. End-tip onto the edge or already placed fill, then spread using suitable tracked plant.
Cover, inspect and repair
Provide at least 150 mm cover before trafficking or compaction. Repair damage with the same textile extending at least 1,000 mm beyond the affected area in every direction.
Cover promptly.
The current general installation guide says temporary uncovered exposure should not exceed seven days. Where a source product sheet states another EN 12224 value, use the more conservative limit unless the current Declaration of Performance confirms otherwise.

Selection limits
Check before specifying.
- Choose a nonwoven grade around filtration, puncture and installation-damage requirements, not mass alone.
- This product is not presented as a woven basal-reinforcement geotextile.
- The constituent polymer is not stated in the source product sheet supplied to CORE.
Product questions
Straight answers about the grade, its role and its limits.
What is MultiTrack 700 mainly used for?
It is a general full-roll nonwoven for separation and filtration in groundworks, drainage, roads, car parks and landscape construction.
How does it compare with MultiTrack 1000?
MT700 has lower declared tensile and puncture values. MT1000 is the more robust general-purpose grade, while MT700 is the economical full-roll option for less demanding interfaces.
Is the 450 m² figure an installed coverage?
No. It is the nominal roll area calculated from 4.5 m x 100 m. Allow for overlaps, cuts, waste and site geometry when calculating quantities.
