Jablite is the UK's largest producer of EPS products for insulation and civil engineering applications

Jablite Geofoam and Voidformer

Overview

Jablite Geofoam is a geotechnical product used in fill applications where a lightweight material is required to reduce stresses on underlying soils or lateral pressures to retaining walls, abutments or foundations. It has been used on projects for road embankments, road widening, rail embankments, bridge abutments, retaining walls, flood and noise bunds, culverts and temporary access solutions.

Jablite Voidformer is used for sheet pile infill panels, secant guide wall and for any void former application.

Jablite Geofoam and Voidformer are manufactured to meet a range of required compression performances (see detailed tables below).
