However, it is best to consult with a qualified engineer or geotechnical expert to ensure that the design meets the required standards for durability and load-bearing capacity. The use of geotech gravel grids may not be necessary if the base is properly compacted and graded. Increasing the thickness of the roadbase or gravel may help to improve the strength of the driveway, but it is important to ensure that the layers are properly compacted. To join the gravel driveway to the garage, you may need to create a concrete span or ramp that provides a smooth transition between the two surfaces. This will help to prevent damage to the garage floor and ensure that vehicles can easily access the garage. To prevent termites from accessing the garage, you may need to install a physical termite barrier around the perimeter of the garage. This can be a strip of material such as stainless steel, termite-resistant timber or plastic, installed vertically in the ground to a depth of at least 75mm. The garage and driveway can be connected by leaving a gap of at least 40-80mm between the external materials and the garage wall, and ensuring that any landscaping or garden beds are kept clear of the garage. Thanks TamFed! 2 2966 I want to build a bigger driveway (without a nature strip) than has been approved under my CDC. I’ve also had a DA approved to build a deck. It looks like I can do this… 0 4882 Very common on rendered homes Smaller suppliers get the lower quality raw materials 6 11951 |
