What is Timbalok

TimbalokTimber crib walls are a cellular mass gravity earth retaining system. One of the oldest gravity wall systems the work on the engineering principle that the mass of the installed system allows it to counteract the forces generated by earth pressure, water pressure and surcharge loading. The system utilises modular components in order to form a cellular structure which can retain heights up to 10 meters. They are quick to build and can be used for retention, as a facing for sheet piles, concrete piles, soil nailed/reinforced earth applications or as a sound barrier. 

EvoGeo are the licensed distributors for the Timbalok system in Ireland. This timber crib system comprises a range of purpose designed interlocking timber components ensuring a cost effective form of construction as well as providing sustainable, environmentally friendly and aesthetically pleasing retaining solutions. The stress graded timber components are European sourced from (FSC) certified forests which is the gold standard in sustainable forestry management.

The timber components are treated with Tanalith E3494 in accordance with BS8417:2011. This water based treatment product is an ecologically friendly alternative to the Chromated Copper Arsenate (CCA) product that some manufacturers use.

Advantages of Timbalok

Timbalok fill material

The normal classification for the fill material is 75mm to 40mm crushed durable stone (eg. Limestone) however the crib wall can be designed with different sized stone as long as we know its specification prior to making our calculations. We can also formulate our design based on the use of recycled concrete or brick if these materials are desirable/available.
