About this deal

Unfortunately, I might have missed some bags of tar, anyone knows what is the best place to find them? You’re likely to come across this problem when the bags have been exposed to cold winter temperatures. Usage: An affordable and eco-friendly way to resurface hardstandings, including car parks, footpaths, haul roads, farm tracks and yards. Use a protective sheet or plastic bag around the mix to avoid it staining or damaging your clothes or any surfaces. Aquacut Aquacut Limited has a dedicated team of craftsmen with decades of experience processing a wide range of building materials such as porcelain, stone, metals, glass, and composites to create functional and beautiful building finishes.

Sticking down something on top could work, depending on the bond to the existing tar- I wonder if some of the plastic/rubber speedbumps would let too much water through underneath? Obviously as this is at the start of the driveway, it's only ever going to be driven over at about 5mph, but my gut feeling is that concrete laid on tar will crack under a heavy load. If you’re using a hot-lay mix like Enviro Mastic, allow about 1 hour for it to cure during cold weather (normally 45 minutes on a hot day). Contains: Tarmac planings or asphalt chippings removed from road sub-base by a cold milling machine.They put a 6m long ridge of asphalt about 100mm wide and 50mm high on top of the edge of the road surface. However, some permanent cold-lay surfacing materials (PCSMs) contain reactive binders, which cure when activated with water. As a ready-mixed macadam, Enviro Mastic can be heated using a mastic mixer and applied as a hot-lay formula.

Easier, I think, to make a raised hump- essentially a speedbump- that diverts the water off the driveway surface.A short answer would be that cold mix bitumen-based surfacing material does what they say on the tin (or the bag) if the installer does what it says on the tin! In some cases, if adequately compacted, DSMs can result in a permanent repair if the location is not subject to heavy traffic. The workability of the Cold Lay Macadam will improve if the outside temperature is above 10°C (50°F). The good news is it’s very likely there is nothing wrong with the formula itself if the bagged asphalt is still within its expiry date. I could make a concrete hump, cheap and easy, but I don't think it's a good idea to lay concrete on top of tar.

Most cold-lay materials, like the range from Instarmac, do not contain any ingredients that will freeze. I've read on the wiki they are dropped by the ghoulish things that appear during the fog, but I did 3 runs and got nothing. However, you still need to ensure the ground is frost-free when applying Enviro Mastic – or, for that matter, any type of cold or hot asphalt. High-quality pothole repair mixes, like the range from the Ultracrete team at Instarmac, are freshly made and come with an expiry date of six months.Mixes like Permanent Pothole Repair and Instant Road Repair (available in 10mm and 6mm grade) from the Ultracrete range set instantly! Always follow the recommended storage instructions to protect materials from cold, damp and draughts (we cover the general storage tips for cold-lays later on). Manufacturers We are proud to partner with the leading manufacturers in the construction materials industry and be an approved supplier. The key for these repairs is to apply almost excessive mechanical compaction, avoiding migration of the binder to the surface or crushing the aggregate. If you have a bag of ready-mixed asphalt that has ‘gone hard’, don’t worry – it’s a very common thing, and especially during cold weather.
