Crack Sealing Video
Colas Solutions was recently awarded the contract to supply and apply crack sealing pavement maintenance treatments around Parliament House in Canberra. Works were completed using SAMIfilla HM, which is a specially formulated hot applied rubberised bituminous material.
Crack sealing a pavement is a cost effect way to prolong a pavements life which will save money in the long run as the cost of replacement can be 20 – 30 times more expensive than a single maintenance procedure. Left untreated, cracks allow water into and beneath the base which leads to pavement failure.
Water is the number one enemy of asphalt and as asphalt is naturally porous; left unsealed, water will penetrate through the pores and cracks and disturb the base – eventually leading to failure of the pavement.
