RetainWall is a software mainly designed for the purpose of designing a concrete or masonry retaining wall. The wall may retain soil or other granular material. It analisis the stability of the wall based on the loads and the resulting base pressure, sliding and excentricities. Loads applied on the wall may consist of self weight, soil pressure, water pressure, live and seismic loads. If the wall is a reinforced concrete structure, the software also supports the reinforcement design. In addition, a soil pressure calculator is also provided.

Retainwall is designed to be an easy application, on-screen trial-and-error method and quick solution finding of the design. A familiar designer can design the wall within minutes. Complete outputs can be viewed on screen or printed.

Operation of the software begins from the initial dimensioning of the wall, earth surface and water levels by clicking on the given dimensions. Next is inputing material properties of the wall, soil, water and reinforcement bars. External loads given consist of live load on the ground surface, seismic load as a horizontal seismic coefficient and any concentrated loads if required. Results of the wall stability can be obtained immediately. If they are not satisfied then another trial can be made very quickly. Final results can be printed.

Using the internal forces of the wall, reinforced concrete design can also be done very quickly. It requires only bar diameters and spacings of the reinforcements.

Retainwal supports three unit systems, i.e. metric, SI and British.
