Hydroseeding is the process of planting seeds by conveying them in water. The seeds are mixed with mulch, tackifier, fertiliser and water, and sprayed on to the chosen area. The mix can be specifically tailored to your site requirements sowing grasses, wildflowers and even trees! We can work to specifications provided by your landscape designer or we can recommend a solution to fit your requirements based on our extensive experience. Seed addition rates can be closely controlled to ensure the correct coverage is achieved.
Hydroseeding is undertaken using a purpose built trailer mounted machine consisting of a water bowser, an engine, a specially calibrated pump to prevent damage to the seeds and materials. This is towed by a 4×4 vehicle. Using specially designed agitation techniques the water, mulch, binders, grass seeds/wildflower seeds and fertilizer are held in suspension. The slurry is then discharged from either a cannon at rear of the machine or from a handheld lance at the end of extension hoses.
The technique lends itself well to sloping ground and difficult to reach areas as we can deploy a hose and spray the mix over 100m from the pump unit.
The allows us to work in areas with no vehicular access and on slopes that would prevent mechanical seeding. This capability fits well with using hydroseeding as a technique to control slope erosion. The reach of the spray from the nozzle allows coverage even where pedestrian access is restricted such as on living walls and next to very steep or vertical drops.
We can also use hose spraying to cover other areas such as lawns and as part of landscaping plans – it is a cost-effective method to create lush, green grass for your garden and outdoor space. We specialise in helping your grass to develop and grow, with good weather and using good topsoil, you could expect germination in just 7 days.
For larger areas with vehicular access our hydroseeding units have a gunning tower. One technician works the gun whilst the other drives the 4×4 towing the unit. This method allows efficient and rapid coverage of ground with up to 10,000m2 being seeded per shift.
Hydroseeding is technically the application of a seed, fertiliser and water mix. At PB Forestry we add and adjust the application levels of the Thermally Refined wood fibre to get the best possible germination performance.
Hydro-Mulching is used on projects with a higher risk of soil erosion and uses different types of wood fibre blends. The combination of the Thermally Refined wood fibres, cross linked tackifiers and activators anchor the fibre matrix firmly to the soil surface for the best possible germination while ‘locking’ the soil surface in place for up to 6 months. As the seeds germinate and grow the root structure takes over the role of binding the soil.
