Big Brook Dam

April 02, 2019

Our team were down south in Pemberton recently to complete hydro-seeding works for Indus Civil & Mining Pty Ltd (Indus) as part of the Big Brook Dam Remedial Works. The embankments were hydro-seeded with a cover crop, while the remaining areas were seeded with native seed supplied by us. Our team worked with the Indus Site Engineers to work around some site constraints and were able to complete the works to the required standard, receiving positive feedback from Indus. We’d like to extend our thanks to Indus for the opportunity to work with them on this project.

It's that time of year....

Summer is coming.  It's time to organise your hydromulching before the Christmas rush.

Award of Wylie Bay Landfill Native Hydroseeding Project

May 28, 2018

GHEMS Environmental’s understanding of native species, cover crop establishment and the associated site soil requirements is extensive. Experience has been gained in farming, natural area and native revegetation management specifically in Esperance over many years and principally throughout the state.

As a result, at the end of May, GHEMS Great Southern regional office was awarded the tender to implement the rehabilitation required to achieve the objectives within the Shire of Esperance’s closure and post closure management plan for the Wylie Bay Landfill site.

 

These objectives include:

 

  • Improve stability of the capping system by supporting top soils and reducing erosion;

  • Reducing the quantity of surface water requiring management at the site through absorption by vegetation; and

  • Improving the visual amenity of the rehabilitated landfill.

 

The Wylie Bay Landfill Site is situated 720km south east of perth and 10km north east of Esperance.

The rehabilitation of this project encompasses the use a hydromulch mix of:

 

  •  locally made microbial soil conditioner;

  • sterile cover crop to offer medium term stabilisation whilst the native seed establishment takes place; and

  • the use of a paper fibre mulch to offer short term stabilisation.

 

This hydromulch mix will be sprayed over the area once it has been direct seeded with a native seed mix that has been designed by the GHEMS team.  The mix will consist of species that are local to the area and are also expected to germinate and establish well. Recruitment of other species that are of provenance to the area is likely to happen through the enhancement of the soil biology as a result of the locally made soil conditioner.

GHEMS are excited to take this opportunity to further showcase the benefits of using techniques to reduce the long-term costs whilst enhancing the rehabilitations results when using GHEMS hydromulch.

 

Stay tuned for photos and updates of the progress!

Learmonth RAAF Base Hydromulching

April 22, 2018

GHEMS Hydromulch are regularly mobilising into regional WA. Recently completing projects in the Wheatbelt, Great southern and Pilbara.

At the end of April, GHEMS were engaged by Exmouth Civil to hydroseed the RAAF Learmonth base with a couch species lawn mix to offer a long-term solution to the dust that was being encountered. As expected, the mobilisation process was extensive, GHEMS deployed a crew of two that were able to drive the Perth to Exmouth journey in less than 24 hours. The 10,000m² took less than a day to complete whilst working under the restrictive measures required by the RAAF airbase. The species of couch used for this project was specifically chosen with the hot and dry winter season and the humid and wet summer season in mind.

WA Soil Biology Conference

March 20, 2018

GHEMS management team attended the 2018 WA Soil Biology Conference hosted by Landsave Organics and the world reknowned scientist Nicole Masters.

Over the past 6 months, GHEMS have noticed a trend towards enquiries into the use of soil medias as well as mycorrhizal and soil biology enhancing products with our hydromulching activities. With our expertise in land management, we understand the starting point for all land management projects is good soil biology and structure.

In all natural areas, the first few inches of topsoil is crucial, this is where the seed bank lies, the good and bad nematodes reside, it is even where the majority of the carbon that dictates the water holding capacity is.

Not only does the soil biology determine the germination of seed, in a complex process, it is the main reason behind all erosion issues encountered. Sure, some will say it is wind, it is water, but why is the soil being moved by those vectors? It is the loose structure, the lack of carbon to hold water and even the lack of plants that should be there in good soil conditions.

With most civil works, where the topsoil is removed or even soil is imported, GHEMS take measures to ensure the soil biology is enhanced to help with the germination of seed where either native, turf/lawn or cover crop is required. To be on the forefront of the industry, GHEMS have been finetuning a microbial soil conditioner which gives our hydroseeding mix the foundations to a healthier and prolific germination and establishment of seed. This microbial soil conditioner is designed to reintroduce the base elements required to achieve the desired results.

Autumn is here...

Hydromulching 

Autumn is here, with the winter rains soon to arrive the need for dust suppression has historically slowed down over this period.  However recently we have had an increase in clients requiring hydromulch due to shire and council requirements. These clients have ranged from large government departments, civil construction companies through to the smaller private land owner.

If you do require dust suppression over the coming months and are not expecting to develop on the land over winter, adding seed to the hydromulch mix is recommended . This will assist in keeping the dust to a minimum through the establishment of the fast growing grass seed.

2016/2017 Summer Season

February 27, 2017

With the welcome addition of our new Mercedes 6,500 litre hydromulching unit, bringing the fleet up to 5 trucks, the GHEMS hydromulching technicians entered the summer season with the goal of averaging 10ha a week up until the Christmas break.

As in every summer season, the race was on. With 5 trucks out on the roads, all units were flat out and every job was managed to be completed by the holiday deadline.

 

Various Wormall Civil and Georgiou developments were the main focus during this period and utilized a variety of different mixes. Local council and shires continued development of their understanding of hydromulching and the benefits it offers brought with it an influx of new clients. These clients ranged from small to medium civil contractors, land developers and private land owners. Many of whom noted the reason for the hydromulching requirement was due to shire/council notice as a result of property owner complaints about dust in the area.

 

This 10ha a week goal was easily achieved and the jobs continued into the new year. With the onset of the cooler months, hydromulching has always had a trend of quietening down although there are still a number of requests due to council and shire notices.

 

GHEMS Hydromulching respond rapidly to customer needs and are always happy to hear from you. To enquire about our competitive prices, no matter how big or small your job is, call us on 9373 7100.

Onslow Hydromulch

April 03, 2016

During early March 2016, GHEMS Hydromulch was contracted by RCR Water to conduct native seed hydromulching at their Waste Water Treatment Plant at Onslow in the North West of WA.

The Hydromulch mix was combined of paper and bonded fiber matrix comprising karri bark fiber, with additions of bonding agents and native fertilizers.

GHEMS was able to suggest and then supply appropriate native seeds for this project, which included Triodia and Enchylaena species, endemic to the area.
