Soil stabilisation with hydromulching

Unprotected soils lose valuable topsoil under heavy rain or wind. With a combination of a geotextile or a coconut mat with hydromulching, we apply a thick, fibre-rich mulch layer that immediately protects the soil against run-off and drying out, while vegetation develops.

BIO-ARMER hydromulching mat

Immediate protection, lasting result

Hydromulching combines a high-volume mulch layer with binders that attach to the soil. The result is a protective membrane that absorbs rain energy, retains moisture and promotes germination of the embedded seed.

  • • Immediate protection against rain and wind erosion
  • • Suitable for steep slopes, construction pits and road verges
  • • Moisture-regulating and soil-improving
  • • Combinable with geotextile for extreme slopes

Combining with coconut mats and geotextiles

For steep embankments, banks and long-term loads we combine hydromulching with natural coconut mats or biobased geotextiles (jute, hemp, straw). The mat is anchored to the slope first, after which we spray hydromulching with seed over the fabric. The textile holds the soil and mulch layer in place, breaks down fully biodegradably over time and leaves behind a firmly rooted vegetation cover.

  • • Coconut mats for slopes steeper than 1:2 and bank zones
  • • Jute or hemp fabric for temporary protection on softer embankments
  • • 100% biodegradable. No microplastics left in the soil
  • • Ideal in swales, verges, railway embankments and water defences
  • • Anchored with biodegradable pins, hydromulching as top layer
Quick facts
  • BIO-ARMER and similar hydromulch mats protect immediately against rain and wind erosion.
  • Coir mats and jute geotextiles are 100% biodegradable within 2 to 5 years.
  • Effective on slopes, embankments, swales, construction sites and after excavation work.
  • Combining with hydroseeding accelerates soil stabilisation through the root structure.
  • Applied in the Netherlands, Belgium and Germany.
