The History of Pre Reinforced Concrete Properties

The period between the First and Second World war witnessed the development of various types of housing systems based on Pre-cast concrete and in-situ concrete, timber, steel and occasionally cast iron construction. There was a surplus of steel and aluminium and in an industry upon till then only geared up for the war effort needed to diversify. These factors drove towards prefabrication. As a result many new varieties of concrete, steel and timber framed systems emerged.

While most systems were intended to provide permanent, long term housing a few were intended only as emergency or temporary solutions. In practise the dwellings did not prove any cheaper to build or maintain as a traditional built house.

By the 1980s some fundamental problems affecting structural stability and durability began to emerge in some of the concrete system built houses. The problems occurred because of either carbonation or the presence of chlorides in the concrete which resulted in the corrosion of the steel reinforcements and subsequently cracking and spalling of the concrete.

The problems of carbonation and the presence of deterimental chloride levels in reinforced concrete houses led to certain concrete housing systems being designated defective under the 1984 housing defects legislation which was then incorporated into the housing act of 1985.

A company named PRC Homes Ltd was set up 1985 to approve license repair schemes for houses designated defective under the 1985 housing act. PRC Homes Ltd a subsidiary of the NHBC in September 1996 ceased to exist. The license repair schemes approved by PRC Homes Ltd are still avaliable today.
The most common PRC property types include, Airey, Unity, Wates, Smith, Reema, Hawksley, Boot, Cornish, Orlit, Parkinson.
