New Muscle Slab[TM] foundation design ideal for Christchurch TC2 & TC3
Press release, Monday 9 June 2014, msHAPPEN Ltd, Christchurch, NZ: A new ready-to-build slab foundation system called
Muscle Slab[TM] is now available for quake damaged homes in Christchurch. Designed and developed by consulting
engineers, Bekker Engineering Design NZ, the new Muscle Slab system is ideal for TC2 and TC3 properties that are to be
repaired or rebuilt.
It is estimated that of the 28,000 homes in the TC3 area alone, 10,000 will likely require a rebuild or significant
foundation repairs, which will take many years to complete. With the Muscle Slab system msHAPPEN Ltd brings swift action
and practical help to those in distress with damaged homes.
At the launch event in Christchurch last Friday msHAPPEN introduced the new Muscle Slab foundation system with
demonstrations of screw pile installation and load and quake simulation deflection testing.
Richard Reid msHAPPEN General Manager says, “It’s more than three years since the February 2011 earthquake, and a
significant number of Christchurch homes still have quake damaged foundations that need to be assessed, repaired or
rebuilt. Identifying which repair strategy or foundation design is best depends on a number of factors from the extent
of the damage sustained, the site specific geotechnical investigation results, to the weight and construction of the
“Muscle Slab is a dependable foundation option for homes in both TC2 and TC3 areas, as it comprises a proprietary
modular structural ribbed ground slab with integrated proprietary helical screw piles. It is also simple and very quick
Because buildings in these areas are prone to damage from liquefaction in future significant earthquakes, a robust
concrete foundation like Muscle Slab is favoured for its ability to better tie the building together. Integral to the
design of this system are ductile screw piles that will allow for ground movement and ensure the slab will remain
suspended and flexible to move with the shake.
Muscle Slab is specifically designed to make homes safer and stronger should liquefaction occur and, with high strength
steel and concrete, it meets the foundation guidelines for TC2 and TC3. Home owners will be pleased to know that the
Muscle Slab system is also competitively priced.
Muscle Slab Features
Muscle Slab is modular, with a profile configurable to any house footprint. It comes in two strengths and is suitable
for any shape or size of home. It is the smart slab for rebuilding or replacement, where high engineering intelligence
meets practical production techniques, providing a ready-to-build solution to Christchurch homes.
Muscle Slab combines a concrete pod slab and a steel screw pile system designed to meet some of the worst geotechnical
conditions possible. It is suitable for re-slabbing under existing houses or new homes. Should an event cause
liquefaction or subsidence of the ground under the slab, in anything but extreme cases, the slab will remain suspended
and flexible to move with the shake.
