Geomembrane is listed among geosynthetic products that is used for insulation purposes, mainly used to provide impermeability and leak proofing. As a geosynthetic product it has some properties such as separation, drainage, etc. to supply what is needed. When we mention geomembranes, we should understand that what is said are membrane structures used specifically for geological purposes.

Geomembranes are materials made out of synthetic raw materials to provide insulation and surface protection which is highly resistant to chemicals. It has high tensile strength, low permeability, extremely resistant to perforations and cracks. There are different types of geomembranes such as HDPE geomembrane and waterproofing geomembrane.
Â
Our RH engineering team can provide solid advice on all types of Seepage control insustry geomembrane, as well as their correct design for projects, including construction details and advice on the general configuration of the project.
