Reinforced Walls with Segmental Block Facings

Segmental Block Facings Cover

Reinforced segmental block wall systems consist of precast concrete blocks stacked to form the wall facing, with the soil backfill behind reinforced with either TenCate Miragrid® GX or TenCate Polyfelt® PEC. The blocks are moulded with an interlocking mechanism that allows them to be firmly interconnected. Geosynthetic reinforcement, laid horizontally in the soil backfill, is connected to the concrete blocks via the interlocking mechanism at specific design heights of the wall. The construction of the reinforced segmental block wall system provides a relatively flexible structure that can tolerate differential settlement without causing distress to the structure.

Installation of the block wall facing, geosynthetics and the soil backfill are all in one construction process. Thus, the construction is relatively fast without the need for special lifting equipment and highly skilled labour. Reinforced segmental block walls have become an accepted practice for a fast, durable, aesthetic and cost effective retaining wall. The system is suitable for applications ranging from landscape terraces, housing developments to major structural walls.
