Canterbury Foam Concrete

The Canterbury Foam Concrete story started in the mid 90’s as a pet project, when Graeme Martin, founder of Canterbury Foam Concrete Ltd, recognized that Foamcrete, due to its flowable nature, would be an ideal product for sealing damp ground under houses.

Working from the front lawn of the family home, in South New Brighton, Christchurch, neighbors, onlookers and passer byes (on their way to the beach) would stop and stare in disbelief as a modern day mad scientist produced a thick white foam, spraying it upon the lawn, and over the trees and bushes like a thick blanket of snow, trialing mixes with cement based grout brews.

 

After countless trials and lab testing a final mix design for Foamcrete was perfected and underfloor ground sealing began.

 

Canterbury Foam Concrete carried out many hundreds of ground sealing jobs in the early years with Graeme on the hose while wife and co-director Cathie as first hand, operated the pump. Cathie also carried out measure ups and quotes during the early period. Interestingly, as jobs were completed, they were recorded by placing a pin onto a map of Christchurch City which was on the wall of the office, {these were the days before google maps}. This showed at a glance, an interesting spread of jobs across the city and highlighted at a glance some of the damp and more troublesome parts of the city.

 

Canterbury Foam Concrete was also involved in filling under runners and redundant pipes in the early days as it is still to this day. This type of work has really accelerated in recent years after the Christchurch earthquake period as Foam Concrete has proved to be an ideal, uniquely flowable, fast, efficient, and cost effective product, to fill voids under relevelled foundations, as well as foundations on piles which have cavities that have formed after earthquake settlement.

THERMOFILL™ GROUND MOISTURE BARRIER

Canterbury Foam Concrete Ltd have been manufacturing and installing light weight Foam Concrete in Christchurch for over 20 years. “Thermofill” is a trademark name for a system of sealing the ground beneath your wooden floor home to stop rising damp.
 
Rising damp can be a major contributor to poor health causing respiratory issues like asthma. A recent report published in an International Medical Journal stated that “Almost 20 percent of hospital admissions of young children with acute respiratory infections could be prevented if their houses were free from damp and mould”
 
Independent tests have shown that up to 40 litres of moisture can rise off the ground every 24 hours. The moisture will often manifest in mould, mildew, musty smells, condensation and high RH values inside the house.
 
While insulation is important, it has long been recognised that it is dampness that is the real villain in the house. The new Healthy Homes Standards introduced by the government effective from the 1st July 2019 now has a requirement to install ground moisture barriers, a key element in the armoury to fight moisture in the home.
 
Dr Larry Bellamy BE (hons) PhD in a report dated 1988: Foam Concrete Under Timber Floors: An Energy Analysis assessed the effects of placing Foam Concrete over damp soil and had this to say: Condensation on the underside of a timber floor can occur where the floor is suspended over damp ground and the inside air temperature falls close to the crawl space air temperature. Much energy is required to vaporise moisture that penetrates the structure. By avoiding underfloor condensation, foam concrete can reduce floor heat losses by up to 90%.
 

·       Canterbury Foam Concrete Ltd can, in most cases, install a Ground Moisture Barrier under the suspended wooden floor of your home, even when there is no crawl space.
