Jute Meshing

Heavy woven jute mesh holds seed and soil intact on slopes, drainage ways and other areas of concentrated water flow, and aids in preventing erosion during rainstorms.

Jute mesh is a material that stays put and generally cannot be lifted by flowing water, wind or vegetation. Because of its mesh formation, vegetation has plenty of growing room.

As jute is a natural vegetable fibre, you get "built in" organic material which will decompose in time and enrich the soils at the rate of 5 tonnes per hectare.

You get immediate protection from erosion in critical areas, as well as a unique mulch.

Jute mesh can be placed onto the area immediately after grading, and can be seeded, pegged and oversprayed with bitumen emulsion.

Jute mesh gives you the freedom to select a variety of grasses or ground covers that best suit local and climatic conditions.

After jute mesh is installed, its neat appearance gives the job a finished look.

Jute mesh is supplied in bales of 548 x 1.2 metres and weighs approximately 350 kilos.

Jute Meshing Soil Saver Specifications

Extent of Work
The work included in this contract is as follows:

Jute meshing of catch drains and steep slope batters etc

Contractors Qualifications
Each tenderer shall submit documentary evidence of his proven ability to carry out this type of work. Such evidence shall include a list of similar projects satisfactorily completed together with a statement of the qualifications and/or experience of the personnel to be employed on the works.

Site Preparation
It is recommended that whenever possible, areas to be Jute meshed should be topsoiled. Wherever possible the area should be free of weed growth large stones or other debris leaving an even surface on which to lay the mat.

Operation

Steep Slope Areas. Greater than 3:1

  • On the steep slopes the mat is laid vertical to the slope.
  • The top end is buried in a minimum 150mm deep trench and pegged at 500mm centres.
  • Where joined the Mat must be overlapped at minimum 150mm
  • At the bottom end of the Mat, lap 150mm and staple at 500mm centres.
  • Where the laps join down the slope, pins should be at 500mm centres.

Placement of Jute Mesh in the Drains and General Flat Areas

Where one strip is laid:

  • The Mat is laid horizontally down the drain.
  • The top end of the Mat is buried in a 150mm deep trench and pinned down at 200mm centres.
  • One pin at 1 lineal metre intervals is placed down the centre of the drain and the outer edges stapled at 2 lineal metres intervals.
  • Each join to be overlapped at 150mm and pins placed at 200mm intervals across the join.
  • The outer edges of the mat to have pins at 2 lineal metre intervals.
  • Where mats join down the middle of the drain they must overlap 150mm and be stapled at 2 pins per 1 lineal metre intervals.

Bitumen Emulsion Application
After the Jute Mesh has been laid and application of slow breaking medium putting anionic bitumen emulsion at the rate of 0.5 litre per m2 of straight product is to be sprayed over the meshed area. In the more difficult slope and water flow areas this rate can be increased to 1 litre per m2.

Seed and Fertilising of the Area
Seeding and fertilising of the area can be carried out prior to the laying of the mat or after it has been laid prior to the application of Bitumen Emulsion. It has been common practice to seed after placement of the mat prior to the application of Bitumen. Placement prior to the laying of the mat can cause considerable disturbance to the seen bed whilst the mat is being laid.
