Slab lifting and relevelling buildings
Many councils are responsible for maintaining the airport in their area.
Even small airports have concrete slabs and buildings that may need relevelling or resupporting from time to time: hangars, taxiways, workshops, terminal buildings, workshops and parking areas. Such problems are caused by ground sinking from drought shrinking, reactive clay in the soil, or broken water pipes or increased loads from heavier aircraft or truck movements.
These days there is a unique solution to these problems – Mainmark structural resin injection.
Mainmark raises, relevels and resupports airport pavements and buildings fast and economically, eliminating bumps, ponding and trip hazards.
There is minimal interruption to airport activities. The work is done at night or low traffic times and one section at a time.
Surprisingly, even heaviest traffic can use the area just 30 minutes after the work is done!
The Mainmark method involves injecting plural component structural resin beneath the footings.
As the resin components mix, they expand, aggressively filling any voids. Soft ground is compacted, resupporting the onground element.
If lifting is required, further injections gradually raise the slab, or building footing. The work is guided by Mainmark technicians constantly laser monitoring.
Recent airport work by Mainmark includes:
- major taxiways at Western Australia’s Perth Airport resupported
- hangar floors at Kingsford- Smith Airport in Sydney relevelled and resupported
- removal of dangerous runway ponding on Korea’s No.2 airport by Mainmark Australia crew
- resupporting hangar pavements for the RAAF at Williamtown.
The Mainmark process is well known and used by council roads engineers, especially where bridge approach slabs, road anchors and culverts need fixing.
