Stabilizing Soft Sites

Top
Clay building sites can be cheaply and effectively stabilized in wet weather by mixing hydrated lime with the clay subsoil before building operations begin.

This initial stabilization rovides a firm, clean, all-weather working surface, and permits the easy access of heavily-loaded vehicles.

Produced in 1963.
