By returning the building’s foundation to its original position, we can relieve the stress on the footings and avert compromising the structural integrity of the building
Why is my home cracking?
When people find cracks in the walls of their home, the natural perception is that there’s something wrong with the foundations – they’re faulty and need major work to replace. But the fact is concrete house foundations are usually as good as the day they were poured into position.
If the foundations have been able to hold the building soundly for the past 30 odd years, it may be that something else has caused the structure to suddenly go so wrong. But traditionally, foundations weren’t engineered to handle all of the conditions and changes that will happen to the home over time.
Do you have an older building with cracks starting to show?
The foundation technology is no longer the same as the olden days. The walls of many older buildings begin to crack for no apparent reason.
The main reasons for this can be quite simple, but often the homeowner is not made aware of the seriousness of managing the moisture of the soil around their home. By helping to make homeowners like you mindful of changing environmental conditions around their homes, we are potentially saving them tens of thousands of dollars in underpinning or foundation repairs.
This is due to Changes in the Enviroment
Natural or man-made changes can have a huge impact on the performance of a buildings foundation. Buildings that were constructed originally on concrete piles or screw piles foundation system are least affected by environmental changes.
Older homes with conventional foundations however, may be affected due to the environmental changes likely caused by:
- Changes in soil moisture content
- Trees planted too close to building
- Taking out nearby trees
- Leaking water pipes
- Stormwater management
- Change in level of water table
The CemJak Difference
How can Cemjak return a foundation back to its orginal levels?
CemJak’s patented lifting system has the ability to apply high lifting pressure and to maintain a gentle slow lift. To achieve this process we apply this method without automated machinery to insure minimal damage to the building while lifting.
Why Cemjak over conventional underpinning?
With CemJak’s method, you avoid incompatible differences in footing depths. Standard footings in older homes of 500-700mm deep are stressed by having to cope beside a 2 metre underpin because the soil at 2 metres moves at a different rate than a half metre deep soil. With the engineering of a new building, it would be imperative to have all footings at the same depth to be considered as structurally sound engineering.
Why Cemjak over chemical injection underpinning?
CemJak is a low-impact process similar to chemical injection underpinning with the added advantage of combined mechanical and injection lift which helps manipulate walls to close cracks while not disturbing compacted clay under the foundations of the building.
Our Environmental Pledge
CemJak’s policy takes the stance that we should all do our utmost to protect our environment, and we believe that no one should have the attitude of just letting someone else worry about it.
A mindset of it not being a problem in our lifetime is inadequate and we should consider alternative options so not to burden our children with our poor decisions.
CemJak uses a fraction of the cement needed in conventional underpins and the greenhouse effect is minimised considerably.
Our process also saves on excavation energy, where normally you would need to freight truckloads of soil offsite and return truckloads of concrete to fill the holes for underpins. There is also the need to remove the concrete underpins when a new building replaces the old.
CemJak has no need for a chemical manufacturer as with chemical injection underpinning. This saves on greenhouse gases in the manufacturing of the chemicals and the long-term effect it could pose on groundwater. The need to remove the injection chemicals when a new building replaces an old home also needs to be considered.
CemJak believes we need to preserve our homes and buildings and not allow them to go to ruin, we just need to be smarter about how we approach our repairs and be more mindful of the environment.
Being more proactive in maintaining a constant soil moisture level around our homes and our neighbour’s property is a great place to start as it will affect all of us in the end.
CemJak Grout is classed as non-toxic and not obtrusive to existing plants and vegetation.
