Introduction

Combigrid combine the advantages of PP geogris and non woven geotextile for even higher reinforcement,filtration and separation.Combigrid are used on boggy substructures or together with material of unfavorable grain size.The type of non woven geotextile may be individually selected to meet the requirements of given project. Combigrid is designed as an all-in-one solution,offers soil reinforcement with added soil filtration, soil separation and subbase drainage performance.The product width 3.95m or 5.95m,length 50m.

Properties Of Combigrid 

*Tensile strength from 20-20kN/m-40/40kN/m

*Max elongation 13%

*Mesh size from 30mm to 65mm

*High strength junctions and stiff ribs

*Good integrity,high node strength

*Stable performance,strong resistance to microorganisms and corrosion

Advantages Of Combigrid

*Immediate stabilization and separation

*Create a stiffer aggregate layer

*Reduce the vertical stress

*Saving of cost and time

*Easy and fast installation

*Environmentally friendly solution

Application Of Combigrid

*Reinforcement of road substructures

*Construction of temporary and technological roads

*Construction of forest roads

*Construction of access roads to windfarms

*Construction of parking lots

*Reinforcement of railway track substructures

*Reinforcement of building foundations

*Reinforcement of substructures under technical floors and mass storage areas
