[Disaster Measures] A must-see for those who want to reduce the amount of leftover soil! Liter Method

Since the construction-generated soil will be recycled on-site, the disposal costs for leftover soil and the costs for new purchases will be significantly reduced. 【Disaster Prevention】

Are you facing any of these issues with construction-generated soil? - Want to reduce the amount of leftover soil disposal? - Disposal costs are high? - It's difficult to find a disposal site that will accept it? ⇒ The self-propelled soil improvement machine 'Litera Method' can solve these problems! Since it is self-propelled, it recycles the soil discharged from the construction site on-site using cement or lime. This results in cost reduction compared to disposing of the soil. Furthermore, it can be operated in narrow yards, and due to its high improvement efficiency, the amount of untreated soil falling off is greatly reduced. With less dust, it can be operated in residential areas and alongside roads. 【Features】 ■ Prevention of environmental destruction and elimination of secondary pollution ■ Significant cost reduction made possible by on-site processing ■ High-quality assurance due to high-performance soil improvement machinery ■ Can be operated in narrow yards ■ High improvement efficiency greatly reduces the amount of untreated soil falling off ■ With less dust, it can be operated in residential areas and alongside roads *For more details, please download the materials or contact us through our website.
