Comtrac®

This geocomposite combines a high modulus reinforcement with an integral nonwoven component to perform reinforcement, separation and filtration functions.

Basic info

Comtrac^® is manufactured from modern geosynthetics with low creep and elongation properties. Longitudinal and transverse strands of the raw material are placed over one another and joined with threads, creating what is known as "Raschelware", a raschel knitted construction.

The advantage of this method of manufacture is that the load-carrying elements run in perfectly straight lines and so Comtrac^® is able to carry tensile forces while undergoing very low strains. Comtrac^® is designed to be used on sites where construction is to take place on ground with low bearing capacity. The immediate take-up of load by Comtrac^®produces a huge increase in load-carrying capacity with very little settlement. At the same time, the excellent filtration characteristics of Comtrac^® ensure that there is no hydraulic water pressure.

The properties of Comtrac^®, especially tensile strength in the longitudinal and transverse directions, can be adjusted to suit the particular application. There are many advantages to be gained by using Comtrac^®. Load transfer at the joints between roll widths is provided by stitching and large areas can be custom-made in advance from the placement plan.
