Geotextile Fabric Ireland | Woven & Non-Woven Geotextiles for Construction, Drainage & Environmental Projects
Geotextile fabric is a permeable synthetic textile used in ground engineering to separate, filter, drain, reinforce, or protect soil layers. SSI Environmental supplies woven and non-woven geotextile fabrics across Ireland for road construction, drainage, erosion control, bog reclamation, and landscaping. Available in rolls, with expert specification advice and nationwide delivery from our Dublin warehouse since 1996.
From road foundations to coastal erosion barriers, from peatland restoration paths to drainage blankets beneath driveways geotextile fabric is one of the most versatile ground engineering products available in Ireland. Choosing the right type and weight for your project is the single most important decision, and it is exactly where SSI Environmental’s expertise makes a difference.
We have supplied environmental and civil engineering products across Ireland since 1996. Our geotextile range covers woven and non-woven fabrics for every application from simple separation under a gravel driveway to high-load reinforcement beneath a haul road, and for specialist environmental uses including bog reclamation and erosion control on peatland and riparian sites.
What Is Geotextile Fabric and What Does It Do?
A geotextile is a permeable synthetic fabric typically woven or non-woven polypropylene or polyester installed between or beneath layers of soil, aggregate, or rock to perform one or more of five core engineering functions:
| Function | What It Does | Typical Application in Ireland |
|---|---|---|
| Separation | Prevents two different soil or aggregate layers mixing together | Road sub-base / soft ground beneath crushed stone |
| Filtration | Allows water to pass through while retaining fine soil particles | French drains, soakaways, drainage blankets |
| Reinforcement | Adds tensile strength to weak or soft ground, distributes load | Haul roads, embankments, soft ground over bog or peat |
| Drainage | Transmits water along the plane of the fabric | Retaining walls, landfill caps, foundation drainage |
| Erosion control | Protects soil surface from water and wind erosion | Riverbanks, coastlines, bog trails, cut slopes |
Woven vs Non-Woven Geotextile Which Do You Need?
This is the most frequently asked question about geotextile fabric in Ireland and the answer depends on what you need the fabric to do, not personal preference.
| Woven Geotextile | Non-Woven Geotextile | |
|---|---|---|
| How it is made | Interlocked polypropylene or polyester tapes woven on an industrial loom | Polypropylene fibres needle-punched or heat-bonded into a felt-like sheet |
| Primary strength | Very high tensile strength, low elongation | Good strength with better conformability to uneven surfaces |
| Water flow | Lower flow rate discrete apertures | Very high flow rate full cross-section is permeable |
| Best functions | Separation, reinforcement, stabilisation | Filtration, drainage, protection |
| Typical uses | Road foundations, haul roads, railway base layers, embankment reinforcement | Driveways, soakaways, French drains, bog restoration paths, drainage blankets |
| Resistance to soil acids/alkalis | Excellent polypropylene is inert | Excellent polypropylene/polyester are inert |
| Ease of cutting on site | Requires scissors or knife frays if not taped | Cuts very easily no fraying |
| Cost | Generally lower cost per roll for equivalent strength | Slightly higher cost for high-grade drainage grades |

Geotextile Fabric Weight Guide Which Grade for Which Project?
Geotextile fabric is specified by weight per square metre (g/m²). Higher weight means heavier, stronger fabric suited to higher loads. Here is a practical guide for Irish project conditions:
| Weight (g/m²) | Typical Use | Example Projects |
|---|---|---|
| 90–100 g/m² | Light separation, landscaping, weed control | Garden paths, driveway edging, under bark mulch |
| 150–200 g/m² | Standard separation and light filtration | Residential driveways, domestic soakaways, light foot paths |
| 300–400 g/m² | Medium duty separation, drainage blankets | Car parks, farm lanes, drainage trenches, bog trail foundations |
| 500–600 g/m² | Heavy duty reinforcement and filtration | Haul roads, embankments, soft ground over peat, French drains with heavy inflow |
| 700 g/m²+ | High load reinforcement, coastal and flood defence | Road construction on poor subgrade, coastal erosion protection, retaining walls |
Applications of Geotextile Fabric in Ireland
Road Construction and Ground Stabilisation
Geotextile separation fabrics prevent the sub-base aggregate from pumping down into soft or clay ground, one of the most common causes of road failure in Irish conditions. A correctly specified woven geotextile beneath the stone layer extends road life significantly and reduces maintenance costs over the project lifetime. This applies to public roads, farm lanes, car parks, industrial yard areas, and temporary haul roads on construction sites.
Drainage French Drains, Soakaways and Drainage Blankets
Non-woven geotextile fabric wraps drainage stone or perforated pipe in French drains and soakaways, allowing water to enter the drain freely while preventing fine soil particles from clogging the stone over time. This is particularly important in Ireland’s clay-heavy soils, where drain failure through silting is common within 5–10 years of installation if fabric is omitted.
Erosion Control on Slopes, Banks and Coastlines
On cut slopes, riverbanks, and coastal embankments, geotextile erosion control fabrics hold soil in place while establishing vegetation. Used alongside containment booms and erosion control matting, they form a complete bank stabilisation system suited to Irish EPA and planning conditions for civil works near watercourses.
Bog Reclamation and Peatland Restoration
Geotextile fabric is central to Irish bog reclamation work. Floating trail paths, access tracks on soft peat, drain-blocking structures, and re-vegetation protection areas all require geotextile fabric specified for low-load, waterlogged, and acidic peat conditions. SSI Environmental’s expertise in both environmental products and geotextiles makes us one of the few Irish suppliers who can advise on both the fabric and the broader site context. See our dedicated bog reclamation page for a full product range.
Landscaping, Gardens and Weed Control
Lighter weight non-woven geotextile fabrics are widely used in landscape applications beneath gravel paths, in raised beds, under decorative stone to suppress weeds without the need for chemical herbicides. A geotextile weed barrier allows water and nutrients to pass through to plant roots while blocking light at soil level.

Frequently Asked Questions Geotextile Fabric Ireland
What is geotextile fabric used for in Ireland?
Geotextile fabric is used for separating soil layers under roads and driveways, filtering drainage in soakaways and French drains, reinforcing soft ground over peat or clay, controlling erosion on slopes and riverbanks, and suppressing weeds in landscaping and agricultural applications.
What is the difference between woven and non-woven geotextile fabric?
Woven geotextile has higher tensile strength and is best for separation and reinforcement under roads and hard-standing areas. Non-woven geotextile has a higher water flow rate and is better suited to filtration, drainage, and applications where the fabric needs to conform to an uneven surface.
What weight of geotextile fabric do I need for a driveway in Ireland?
For a residential driveway, a 150–300 g/m² non-woven geotextile is typically sufficient for separating the sub-base from underlying ground. For heavier-use areas such as lorry access or commercial yards, a 300–500 g/m² woven fabric is more appropriate. Contact SSI Environmental for site-specific advice.
Can geotextile fabric be used on boggy or peaty ground in Ireland?
Yes. Geotextile fabric is specifically recommended for construction on peat or boggy ground, where it prevents aggregate from sinking into soft substrate and distributes load over a wider area. It is also used in peatland restoration and bog reclamation projects for floating paths and drain-blocking structures.
How long does geotextile fabric last in the ground?
High-quality polypropylene geotextile fabric is resistant to biological degradation, soil acids, alkalis, and UV radiation when buried. Installed and covered correctly, a well-specified geotextile has a service life in excess of 50 years.
Does geotextile fabric stop water draining through?
No geotextile fabric is permeable and allows water to pass through freely. Woven fabrics have lower flow rates than non-woven, but both allow free drainage. Geotextile membranes (impermeable liners) are a different product used in pond lining and landfill applications.
Where can I buy geotextile fabric in Ireland with fast delivery?
SSI Environmental supplies woven and non-woven geotextile fabric across Ireland with nationwide delivery from our Dublin warehouse. Contact us on 01 8665676 or at enquiries@ssienvironmental.ie for a quote and lead time on your required specification.
Is geotextile fabric required on Irish construction sites under environmental conditions?
On sites with EPA licence conditions, planning conditions, or proximity to watercourses, geotextile fabrics used in conjunction with drain protection and spill containment forms part of a site’s standard best-management-practice environmental controls.
