Separation & Filtration

Weak or variable ground usually presents considerable challenges for subgrade stabilisation. Geofabrics’ subgrade stabilisation solutions include bidim non woven geotextiles to provide separation and filtration between the subgrade and base layers.  

Subgrade & Base Stabilisation

Tensar TriAx geogrids are used to provide effective confinement of granular fill in subgrades. This results in a stiff mechanically stabilised layer, capable of controlling differential settlement, reducing aggregate depths by up to 30%, capping weak deposits and increasing bearing capacity.

In tough times, faced with ever increasing earthworks costs TenCate Mirafi® RSi Multifunctional Woven Geotextiles offer engineers and contractors significant cost savings and improved road pavement performance. TenCate Mirafi® RSi offers engineers and contractors a new solution for cost effective construction using site-won material.

Asphalt Reinforcement

Increased traffic imposes higher strains within asphalt pavements which fatigues the asphaltic layers, resulting in asphalt cracking and water penetration into the pavement, which leads to further deterioration. Asphalt reinforcement provides fatigue resistance, mitigating subgrade rutting and reducing cracking through improved shear resistance.

Geofabrics offers Tensar AR-G a proven pavement reinforcement technology for retarding cracking and controlling deformation as well as the specialist range of GlasGrid asphalt reinforcement products that can be used in asphalt overlays as thin as 40 mm.

Surface Sealing

Crack reflection and water penetration are a major cause for concern for road engineers. Geofabrics offers a solution in Sealmac, a geotextile paving fabric that is impregnated with bitumen to act as a stress absorbing membrane under chip seals and asphalt pavements as well as Bitac bandage strips used under asphalt to control crack reflection and seal construction joints.

Subsoil Drainage

Megaflo panel drain provides the dimensional stability and field-proven structural strength for quick, effective subsurface drainage.
Performance is the distinguishing feature of the panel drain due to its ability to rapidly collect and remove water. Compared to round pipe, Megaflo has twice the inflow capacity for an equivalent length and will drain water in less than 60% of the response time. Its slim 40 mm wide profile permits faster and more cost effective installation in a narrower trench.
