General Information

Coir (Coconut fiber), is made from well cleaned, high strength, fresh water cured coconut fiber . Coconut fiber is extracted from coconut husks which are submerged in fresh water streams or storage tanks for a period of several months. During this process known as retting, water constantly flows through the coir fiber matrix removing impurities present in the fiber. The clean fiber is extracted and spun into yarn which is then woven into Coir Mat.

GeoLog coconut fiber logs are comprised of 100% biodegradable coir fiber tightly bound by a coir yarn netting which maintains its density & shields the structure against mechanical & hydraulic stresses.

Product Information

Geolog Coirlogs are made from natural fibres which degrade over time whilst encouraging natural revegetation for long term security & protection. Geolog systems do not require bulk
earthworks or invasive site preparation prior to or during installation.  Geolog Coirlogs are extremely easy & quick to install. Timber stakes either driven adjacent to or through the units secure them in place. Geolog Coirlogs are significantly less expensive than drop structures or rip rap protection. Coirlogs installation does not require specialist labour or equipment & can be installed by a small inexperienced crew.

Applications 

GeoLogs are deal for riverbank scour protection, silt entrapment, wave dissipation, runoff & stream diversion, spill containment as well as aquatic/wetland plant protection & buttressing on revegetation projects.  Coir logs are attached at the edge of the bank and secured by wooden pegs. Pegs may be used on alternate on the outer edge to firmly secure the log to the bank.

Features and Benefits 

• Strength. GeoLogs are durable & remain structurally sound throughout the natural life of the system. GeoLogs withstand wave energies which often require ‘hard armour’ solutions.
• Filtration. Rather than providing an impermeable barrier, GeoLogs allow water transmission whilst trapping sediment, reducing turbidity in the main water body.
• Environmental. GeoLogs are made from natural fibres which degrade over time whilst encouraging natural revegetation for long term security & protection. GeoLogs systems do not require bulk earthworks or invasive site preparation prior to or during installation.
• Construction. GeoLogs are extremely easy & quick to install. Timber stakes driven adjacent to the units secure them in place. Feel free to consult our staff for advice on installation for each individual project.
• Cost effective. GeoLogs are significantly less expensive than retaining walls or rip rap protection. GeoLog installation does not require specialist labour or equipment & can be installed by a small inexperienced crew.
