Commonly referred to as a floating slab because it ‘floats’ on the soil, the deeper concrete around the edges hold it in place and in colder climates, ensure the slab edges are buried deep enough to remain below the frost line in winter.īut the interesting (or troublesome, depending on whether your pipes are working beautifully or not) thing about slabs is that thehome’s sewer and drainage pipes, and sometimes even the electrical circuitry, have to be put in place before the concrete is poured. The slab itself is then about 100mm to 150mm thick and has wire mesh andsteelreinforcing bars within it (reinforced concrete, or ‘reo’). The rest of the slab sits above a 100mm to 150mm bed of gravel then a layer of plastic to keep out moisture and possibly termite barriers. Houses that are built on slabs have a concrete beam around the edge that is usually about 600mm deep. Why it’s so hard to repair sewer pipes under slabs These new, no-dig pipe repair solutions, such as cured-in-place (CIPP) advanced composite resin pipe relining have been used with great success across Europe, Canada and the United States since the early 2000s to reline broken water pipes without excavating, and are now available in Australia. But for anyone needing to repair a sewer pipe under a slab, the most exciting development is use of these incredibly strong materials for relining broken sewer and water pipes. Today, composite resin compounds are used to make a whole range of products and equipment such as aeroplane bodies, elite sports equipment (cricket bats, tennis rackets and hockey sticks) and sleepers for train tracks.
Collapsed drain pipes under a concrete slab aren’t the end of the worldĪs distressing as this news might initially be, however, it’s no longer the end of the world, thanks to advances in composite resin technology which occurred as we waved goodbye to the 20th century.
