Intertidal gravel track defying the odds

They said this track would never last, and they were probably right. However, thanks to a timely DirtGlue intervention, the track now has a fighting chance of surviving.

Project: Intertidal path, Howrah
Date: October 2016
Client: Clarence Council, DirtArt

Howrah Beach and Little Howrah Beach is separated by an 80 metre section of rocks. The walk across the rocks is hazardous, especially when the tide is up. The beaches attract a lot of walkers so providing a safer path between the beaches made a lot of sense. Clarence Council devised an ambitious plan to construct a path over the rocks, ambitious because high tides would rise above the level of the path.

In February 2016, the path was constructed. Within weeks, high tides had smashed the path and it had to be repaired, and then repaired again. In April, Clarence Council contacted us to see if DirtGlue® could save the track. To demonstrate the capabilities of DirtGlue® we treated a 10 metre section of the track. Six months after the application, the treated area of track was as firm and secure as the day it was treated. Unlike the rest of the track which was suffering badly.

Having passed the trial, Clarence gave us the go ahead to treat the rest of the track with DirtGlue®.

The path has been saved. As well as creating a long lasting sealed gravel surface, DirtGlue has also locked-in the rocks that contain the gravel.
This project is a great example of DirtGlue working in extreme environmental conditions.

Eco-carpark by the beach at Seven Mile

From a distance, it looks like any normal red gravel car park. However, get up close, and you’ll discover that the gravel surface is solid, rock solid.

Project: Red gravel and DirtGlue® car park in Seven Mile Beach, Tasmania
Date: September 2016
Client: Clarence City Council


There are numerous red gravel car parks along the coastal road at Seven Mile Beach, 15 minutes east of Hobart. Red gravel is an effective short term solution to surfacing these car parks – the gravel is easily available and relatively low cost. However, it has its shortcomings; the gravel quickly becomes displaced due to cars driving on it and bad weather. Typically the surface develops pot holes and when this occurs, the Council sends in a crew to reset the levels and lay more red gravel. Another major issue is the loose gravel from the car park gets washed into the drains and underground pipes. Over time, this causes significant problems for the drainage system.

Clarence Council approached us to see if DirtGlue® could provide a better long term solution for this car park’s maintenance strategy.

The Council wanted to steer away from concrete, bitumen and asphalt, as this was cost prohibitive and also not appropriate for the site.

For this scenario, using DirtGlue® Industrial was a great fit for the project – a long lasting sealed gravel surface, cost effective, environmentally safe and a natural finish that fitted in with the local environment.


After the Council had prepared the base and laid the gravel it took just half a day for our GreenTrack contractor (D Howard Landscapes and Excavations) to apply the DirtGlue and roll the surface. The car park was closed to the public for just four days.

GreenTrack and DirtGlue® delivered exactly what was expected. This 230 square metre car park at Seven Mile Beach now has a sealed red gravel surface; it is rock hard and wearing well. From a distance it looks no different to the original red gravel car park, local residents may not have even noticed the change.

Inspecting the drains around the site, it can be seen that the drains being fed by water running off the car park are relatively gravel free. Whereas, other nearby drains are clogged with gravel washed in from red gravel paths along the road side.

Stabilising walking tracks in the Ku-ring-gai Wildflower Garden

Stabilising walking tracks in the Wildflower Garden

Ku-ring-gai Wildflower Garden is one of Sydney’s best kept secrets. Situated in St Ives, the 123 hectares of urban bushland is a great spot for bush walking and outdoor adventure.

There is a network of tracks through this extremely environmentally sensitive area. The local council has major issues with track erosion, especially when it rains. The soil is very sandy and walking tracks regularly wash out during heavy downpours. This leads to the paths being closed to visitors for safety reasons. The council needed to stop the erosion and DirtGlue was the best solution.

Tracks were treated with a surface application of DirtGlue Industrial. Quite simply, spraying a mixture of DirtGlue and water onto the dirt. Well known problem areas were treated as a priority, stabilising paths, steps and rock structures. The contrast between treated and untreated areas is significant.

Furthermore, because of a preference to avoid cement/concrete in this environmentally sensitive area, parks staff have installed signage posts into the ground using Dirtglue instead of concrete.

On a quiet walking track on Hobart’s Eastern Shore, Greentrack collaborated with Clarence Council on the installation of a memorial seat. Usually, this style of seat is bolted into a concrete slab, however for this installation the goal was to avoid using concrete.

This seat was bolted into a slab of limestone gravel and DirtGlue Industrial. Limestone gravel was chosen to blend with the gravel in the walking track alongside.

The project was a great success. The bench sits very naturally in the bush setting and no concrete was used.

Walking track connects West Hobart Oval to the community

gravel and DirtGlue walking track

In April 2017, Greentrack installed a gravel and DirtGlue walking track for the City of Hobart, as part of a major development of the West Hobart Oval.


During the Council’s project planning, the feedback from the community consultation requested a sealed track that didn’t suffer potholes. However, the community also didn’t want concrete or bitumen.
Gravel and DirtGlue was a great solution.

The paving for the track was constructed with DirtGlue Industrial and a blend of locally sourced gravels, Tasmanian Gold and Blue Metal. Steel was used to edge the pathway.


The outcome was a long lasting, sealed gravel track, radiating the soft natural colour of Tasmanian Gold. Furthermore, like all Greentrack’s products, the bonding agent, DirtGlue Industrial, has zero toxicity and is friendly to the environment.
