Rip Rap - FAQs

How is EARTHLOK different to rip rap?

Rip rap is a layer of loose rock, strategically placed to dissipate the force of water and prevent erosion from water action.


EARTHLOK, unlike rip rap, is not loose rock. It is a precast, flexible concrete mat made up of consistently sized, pyramid-shaped, 50 Mpa concrete blocks that are interconnected with a high-strength, chemically resistant geogrid.


EARTHLOK is more durable and resistant to extreme weather events than rip rap alternatives.

How is EARTHLOK more environmentally friendly than rip rap?

EARTHLOK has a significantly lower carbon footprint compared to rip rap projects. Each stage of the manufacture and project installation process is up to 20× lower than the rip rap alternative. One truckload of EARTHLOK product delivered to site is the equivalent to up to 20 truckloads of rip rap.

Made from recycled materials, EARTHLOK has been awarded a 3/4 Greenstar rating. It is a unique product to protect from erosion while at the same time helping civil engineering firms and local government bodies to meet their sustainability goals. In this regard, EARTHLOK is the clear market leader in Australia, ahead of traditional products such as rip rap.

What are the benefits of EARTHLOK over rip rap?

EARTHLOK is both faster to install and requires less maintenance than the rip rap alternative.


The installation time of EARTHLOK is significantly faster than rip rap, due to EARTHLOK being packaged in a ready-to-install roll form (up to 100 m2 per roll) that can be installed in a matter of minutes. As rip rap requires the placement of a geofabric underlay prior to placement of rip rap rocks, EARTHLOK is far quicker and easier to install.


In fact, EARTHLOK is up to 20 times faster to install than rip rap, and up to 1000 m² can be installed in a single day.


Whist rip rap projects have been known to be reconstructed moderately frequently, and requiring maintenance after major weather events, EARTHLOK is designed to eliminate the need for potential reconstruction. It requires minimal maintenance due to its design and structural integrity.


Due to the above factors, EARTHLOK projects will almost always be more financially and environmentally cost-effective than the rip rap alternative.

How long do rip rap structures last vs Earthlok?

Rip rap structures are prone to having their structural integrity compromised due to inclement weather events. 


EARTHLOK can withstand greater inclement weather events than rip rap, due to the construction of the EARTHLOK blocks being interconnected and the pyramid shape of the blocks, which are forced down into the subgrade under high velocity of water flow. In other words, strong water flow increases the performance of EARTHLOK, whilst at the same time it decreases the performance of rip rap.

EARTHLOK has a minimum performance life of 50+ and 100+ years respectively for non-vegetative and vegetative applications. Whilst individual rip rap rocks will last this long, the structures themselves often do not, due to being compromised in major weather events.
