Natural or manmade slopes are mostly eroded by surface water runoff in absence of sufficient vegetation cover. While natural vegetation is proven choice for sustained erosion control, its success depends on adequate rainfall year after year and the presence of initial binding material in the soil. However, due to changing weather conditions, natural vegetation requires the help of external reinforcement for holding its root matrix together in adverse climatic conditions in order to provide adequate vegetation cover as permanent protection against erosion.

Tuflex geonet laid on slope surface alongwith natural grass or turfing, reduce the velocity of water runoff and help in controlling surface erosion of slope by providing permanent reinforcement to root matrix of vegetation cover.

LET 'TUFLEX GEONET' PROTECT THE SLOPES
 

For construction engineers, high slopes of embankments as well as cuttings for roads and railways, slopes of rivers banks, dams, reservoirs and hill slopes, often pose the serious problem of erosion of soil from slope surface during rains. Due to surface water runoff, small rivulets, gullies and ultimately erosion ditches are formed thereby endangering the stability of the slope. Filling with soil, rip rap or boulder pitching and normal turfing are various methods being adopted to check erosion but often require repetitive maintenance.
There is a permanent solution.
 

'Tuflex Geonets’
 

Providing Tuflex Geogrids on soil slopes surface will firstly prevent erosion of soil by retarding the velocity of water runoff on slope with its three dimensional profile and promote water percolation in soil as well for natural grass to develop. Once natural grass is established on the slope surface, the grids act as permanent reinforcing medium for grass roots because of intertwining of grass roots in the mesh apertures, thereby helping in generation of dense grass cover by preventing the roots from washout in adverse weather conditions

For intermittently wetted as well as dry slopes, Tuflex Geogrids & Gabions as permanent erosion protection measure have proved to:

▫

Prevent soil erosion on high embankment slopes

▫

Retard velocity of water runoff on slope surface with three dimensional profile of mesh.

▫
 

Prevent erosion of existing vegetation on the slope surface due to intertwining of grass roots with mesh apertures.

▫

Help in generation of dense vegetation cover on the slope surface.

▫

Avoid repetitive maintenance.

▫

Provide a cost effective permanent erosion control measure.

Road and Railway Embankments :

High embankment slopes of roads and railways, often constructed with locally available soil are subject to extensive soil erosion due to water runoff in rains. Geogrids placed on slope surface prevent soil erosion by breaking down the velocity of runoff flow due to multiple check dam effect of its three dimensional grid profile. As natural grass takes it roots through the grid, its intertwining with grid apertures provides reinforcement to root mat. Vegetation growth is thus accelerated resulting in a permanent protective cover to earth slopes.
 

Rock Slopes and Cliff Faces :

The erosion of freshly cut rock slopes and cliff faces creates potential hazards to road users from falling stones fragmented and dislodged by weathering.

Tuflex geogrids fitted to the slope face by means of rock spikes, provide protection against such hazards. Weathering of stones is retarded and loose material is arrested and prevented from uncontrolled displacement like landslides.
