| CONCRETE PANELS |
|
| The use of precast concrete panels, with galvanised steel strip reinforcement to strengthen the soil behind, is a well-established technique, with over thirty thousand structures built worldwide over the past thirty years |
|
| Phi Group's rectangular concrete panel system maximises the benefits resulting from reinforced soil by providing:- |
|
| • |
A cost effective solution typically 50% of the cost of a reinforced concrete retaining wall. |
| • |
A robust structure that can accommodate high working and dead loads associated with bridge abutments and other large retaining walls. |
| • |
A mortar free facing and self-draining system. |
| • |
A finished wall that is tolerant of settlement without cracking. |
| • |
A construction method requiring no structural foundation or temporary propping, with all work carried out from behind the panel facing. |
| • |
An end product with no curing or shutter stripping involved. |

| Specification |
| The standard concrete panel measures 2.0m x 1.8m. The steel reinforcement strips, normally 50mm wide by 4mm thick, are hot dipped galvanised to give a design life of 120 years. Steel strips are ribbed if necessary to increase frictional resistance within the fill material. |
|
| The granular fill material used with the steel strips is specified as class 6I or 6J in the Department of Transport Specification for Highway Works series 600. |
