GEOMAS GEOKOMPOZIT SAN. MÜH. TIC. A.Ş.

The sealing technology of BentoShield, effectively combines the unique swelling performance of sodium bentonite granules with two high strength geotextiles. Once Bentoshield is hydrated, it forms an impermeable barrier against liquids, water vapor and gases. Bentoshield geosynthetic clay liners are very effective saeling liners for wide variety of environmental projects from landfill to mining areas, lagoons and canals. Geomas presents the most economical and effective solution for all your specific requirements with factory controlled BentoShield geosynthetic clay liner range. BentoShield presents remarkably higher hydraulic performance when compared to a meter of conventional compacted clay liner. In addition to superior hydraulic performance, BentoSheild effectively overcomes the technical difficulties confronted during installation in compacted clay applications and provides a cost effective solution.

Bentoshield MAX LM is manufactured by a needle-punching process, in which the fibres of the lower non-woven geotextile are pushed through the bentonite layer and secured in the retaining upper woven layer. This process links the geotextiles and contains and confines the bentonite. Following the needle-punching process, an LDPE sheet is laminated to the needle-punched geotextile through a hot-melt glue application line. Bentoshield MAX LM is satisfactory for use as a fully-bonded Type A waterproofing protection as defined in BS 8102 : 2009 for the waterproofing of new and existing structures. The product can be used externally on horizontal floor slabs and vertical walls to provide an effective barrier to the transmission of liquid water where Grades 1 to 3 waterproofing protection are required, as defined in Table 2 of BS 8102 : 2009.

Naturally occuring water accumulated in the ground may cause deterioration of the structure over time. Drainage geocomposites can be used to maintain the continuous flow even under high loads at foundation walls, retaining walls, green roofs, plaza decks and beneath slabs. Traditional drainage materials such as gravel can be replaced and also protection of the building’s external waterproofing layer is secured. GeoDrain are drainage composites present wide variety of different type of cores which is connected to geotextile either at one or two sides. All GeoDrain products are lightweight, strong, flexible, easy to handle and fast to install in one operation. They deliver high flow transmissivity per unit volume with consistent, uniform and excellent long-term performance. The selection of the appropriate GeoDrain geocomposite for the drainage of the structure is made by analyzing different parameters.
