A bit rusty with my engineering lingo (having been a civil engineer in a previous life) but I believe the image below is called geotextile fabric. It is used on steep slopes to reduce erosion, protect from slips and allow grass to grow through.

Anyway Im after some for DIY purposes but cant find this in joe public stores and the Google hits appear to be for commercial suppliers only.

Anybody here used this?


Edit: Added link to image.

I expect from your post that you want erosion control blanket as below.  Not widely used in my locality (Marlborough), we use bark mulches on smaller projects, and larger projects some hydroseeding.

Perhaps contact your local Civil, earthworks contractors and see if they can sell you some.  Or agricultural suppliers, we have a Hynds depot/store that would source those materials.  

We use Geotextiles such as Bidum for filtration and or separation of materials.  For example between rock protection and natural ground to prevent scour erosion.  Or when placing pavement sub base over silts or clay ground to prevent migration of fine materials, and some support.  For subsoil drains we tend to wrap the trench containing the drainage gravels and drainage pipe, to provide a greater filter area, rather than using a filter sock over the pipe.

Biomac C is a coir fibre erosion control blanket used for temporary soil erosion protection and to aid in the re-establishing of vegetation in landscaping applications. Biomac C provides initial erosion protection to seed and young plant from the extremes of rain, wind and sun during the critical germination and development stage.


Biomac C is supplied in different grades for erosion protection and soil stabilisation projects. The choice of coir mat is dependent on the slope gradient, rainfall intensity and application.

Thanks for your comments kotuku4. I've emailed the Biomac C people but no response yet. The Biocoir people came back to say I can buy it at Bunnings (bit pricey but I'll see if I can get trade prices through a mate).

Correct it is for erosion control on a steep bank behind our house. The bank is too steep for bark mulch.

I looked into Hydro seeding but couldnt see any cost effective (or DIY) way to do it. 

On a ride over the weekend I noticed erosion control blanket as per my photo and am wanting to track that down.

I can understand these engineered materials being very expensive.

Mulch only works on moderate slopes if long shredded material, not a screened bark or small material as this tends to roll down the slope.

A DIY option I can think of is used wool choir backed carpet, pin it to the slope with wire staples, cut or punch holes for planting.  Or perhaps other natural woven fabric.
