2.25m x 50m Geotextile Membrane / Driveway Fabric 90g (112.5m2/Roll)

What is 90gsm Non-Woven Geotextile Membrane?

90gsm Geotextile Membrane is a permeable fabric engineered from synthetic fibres, which are heat-bonded to create a robust, felt-like sheet. 

Its 90gsm grade is a popular choice for light to medium-duty applications, offering an excellent balance of strength, permeability, and cost-effectiveness for domestic driveways, paths, patios, and general landscaping projects.

Unlike woven geotextiles (which excel in high-strength reinforcement), non-woven fabrics offer superior permeability and filtration characteristics. This allows water to pass through freely while preventing fine soil particles from migrating and contaminating drainage layers or sub-base materials. 

The membrane's primary functions include ground stabilisation, sub-base/soil separation, filtration, and effective weed suppression. Ideal for use beneath driveways, paths, patios, permeable paving, soakaways, and under decorative aggregates, this 90gsm fabric helps prevent rutting, sinking, and intermixing of layers, leading to a more durable, stable, and low-maintenance finished surface.   

Applications

• Domestic Driveways & Light Vehicle Parking Areas: As a separation and stabilisation layer beneath MOT Type 1 or other hardcore sub-base material.
• Garden Paths & Patios: Underneath paving slabs, block paving, gravel paths, or decorative aggregates to prevent sinking and weed growth.
• French Drains, Soakaways & Land Drains: To wrap perforated drainage pipes or line trenches, acting as a filter to prevent clogging by soil fines.
• Weed Control Under Decorative Aggregates: Ideal under slate chippings, gravel, or bark mulch in garden beds and borders.
• Under Artificial Grass Installations: Provides a stable separating layer between the sub-base and the artificial turf.   
• Erosion Control (Mild Slopes): Can help stabilise soil on gentle embankments when used beneath a covering layer like stone or mulch.
• Wrapping Soakaway Crates/Attenuation Tanks: Prevents surrounding soil from migrating into and reducing the void capacity of modular soakaway systems.   

Benefits

• Effective Ground Separation: Prevents the intermixing of the sub-base aggregate layer (e.g., MOT Type 1) with the underlying subgrade soil. This maintains the structural integrity and load-bearing capacity of the sub-base, preventing it from being lost into softer ground.   
• Enhanced Ground Stabilisation: Helps distribute applied loads (from vehicles or foot traffic) more evenly over a wider area of the subgrade. This reduces localised stress, minimising rutting, sinking, and differential settlement of the overlying surface.   
• Efficient Filtration: Allows water to pass through whilst preventing the migration of fine soil particles. This is essential in drainage applications like French drains, soakaways, and around perforated pipes, ensuring the drainage aggregate remains clean and functional.   
• Robust Weed Suppression: When used as an underlay beneath aggregates, mulch, or paving, it acts as a strong physical barrier, significantly inhibiting weed growth from the underlying soil, thus reducing garden maintenance.
• Increased Lifespan of Paved Surfaces: By maintaining a stable and clean sub-base, it significantly contributes to the longevity and performance of driveways, patios, and pathways, reducing the need for premature repairs.
• Potential Sub-Base Reduction & Cost Savings: In some applications over moderately stable subgrades, the use of a geotextile separator can potentially allow for a slight reduction in the required depth of expensive sub-base aggregate, leading to material cost savings.
• Durability & Chemical Resistance: Manufactured from synthetic polymers, the fabric is rot-proof, mildew-resistant, and unaffected by common soil-borne alkalis and acids.
