Signs that an existing crossover may require attention include substantial cracking, broken concrete, deteriorated edges or an uneven transition into the driveway. Customers may also require a replacement when changing the driveway layout or carrying out other property improvements that affect vehicle access. Where old concrete needs to be removed, concrete excavation can form the first stage before the replacement area is prepared. Ground preparation, formwork, reinforcement, levels and concrete placement all influence the finished crossover. The connection between the crossover and driveway deserves particular attention because poor alignment can leave an abrupt change in level where vehicles pass from one surface to another. For properties around Armstrong Creek, Torquay and Ocean Grove, crossover work may be combined with a new concrete driveway or adjoining footpath where several external concrete areas are being upgraded. Any requirements applying to the specific site should be established before work proceeds rather than assumed.
