First, mix the cellulose fiber mulch and cocopeat together, followed with grass seeds, fertilizer amelioration materials and a geobinder tackifier in a pail full of water. Continue loading ingredients and mixing process until mixture forms a consistent, uniform and homogeneous slurry mixture ready to be applied. Fig. 3 shows the hydroseeding

The slurry was applied manually on the soil surface as shown in Fig. 4. Application started from the top of the slope down to the toe. Exposed area at the top and toe of the slope were completely covered by applying the mixture 15 inches beyond the top and toe of the slope. Spots that might not be covered with the hydroseeding mixture were simply hydroseeded again. Hydroseeded areas were regularly watered daily during the dry days for the first

With the hydroseeding completed, the coconet is installed over the entire hydroseeded area as shown in Fig. 5. To ensure total coverage of the slope, nets are laid adjacent to each other and were anchored securely on the slope with bamboo pins or any other appropriate material(s) depending on the nature of the slopes.
