Porotherm has been a mainstay of construction across Europe for decades. Since its introduction into the UK in 2008 it has become well established as an excellent alternative to traditional masonry such as concrete blocks, as well as other systems such as timber or lightweight steel frames.
The range of benefits offered by building with Porotherm cover a broad spectrum of subjects from economic to environmental to lifestyle.
An average of 30-40m2 per man per day is easily achievable; much faster than traditional masonry
Floors can be placed without the need for normal backing up so the external envelope can be completed more quickly
Porotherm’s ZeroPlus mortar can be used at 0°C and above, meaning projects can gain extra working days in winter
Porotherm uses around 95% less water. In a typical 212m2 building, concrete blocks will consume 1060 litres of water compared to just 72 for Porotherm.
Work is less reliant on the local water supply
The system takes less time to achieve a watertight shell
The external skin can be removed from the critical path to allow parallel working
The compressive strengths of Porotherm’s core range are typically 10 N/mm²
One block fits the majority of requirements, as a result there is no need to keep multiple blocks on-site, reducing the risk of wrong-block use and optimising storage space
Porotherm blocks are generally lighter than concrete, allowing workers to maintain steady production rates without the risk of repetitive strain injuries
Precision engineering means no sharp corners, reducing the risk of cuts
ZeroPlus mortar is applied with a roller, reducing dermatological risk
30% of materials from alternative, recycled or secondary sources (MARSS)
Life expectancy of more than 150 years and blocks recyclable at end of life, for example into hard core.
