Historically, laying paving slabs on sand was a common practice, particularly in areas with sandy soil. This was because it was a relatively easy and cost-effective way to create a functional outdoor living space that was often installed for the practical hardstanding aspect rather than its aesthetic appeal. Filling gaps between patio pavers is one of those jobs you can just keep putting off – but we all know it needs to be done. There’s nothing worse than getting halfway through a job before realising you’re missing a vital tool – especially if your mortar has already started setting. So to avoid that scenario, here’s the essentials of what you’ll need to get started: This depends on the weather a little. If it’s hot and sunny, most polymeric sands will set up between 24 and 72 hours.

For these reasons, creating a patio on sand is generally considered a temporary solution, and is not recommended for long-term use.Unfortunately, some "cowboy builders" may still use this approach as a shortcut to cut costs and time in the installation process. It is important to be cautious when hiring a contractor and to ensure that they are using proper installation methods and materials to ensure the longevity and safety of your patio. If you are looking to create a patio that will last for many years, it is recommended that you invest in a full mortar bed installation, which provides a more secure and stable base for your slabs. Conclusion Yes. You should always fill expansion joints. Expansion joints account for cement’s natural properties of expansion in the heat and contraction in the cold. Be sure to choose a flexible sealant. For this it’s best to use a sharp sand, which is particularly well-suited for patios and gardens, as it will prevent moles or rats from burrowing underneath your slabs and weakening them. Personally here at Bridge Street Stone, we recommend mixing between 4 and 6 parts sharp sand to 1 part cement, before adding a bit of water. Scoop four shovels full of sharp sand onto the plastic sheet to make mortar for general use, such as laying paving slabs, or three shovels of sharp sand to create a patio pointing mix (for filling the gaps between paving slabs). The two cement slabs will always be expanding and contracting independently, so you need to fix it with something that is a little flexible – not cement based.Once the sand has been compacted, use a spirit level to ensure that the surface is level and even, although remember to ensure there is a slight slope away from your home to allow rainwater to run away. If you notice any high or low spots, use a shovel to adjust the sand accordingly. Step 3: Lay the Slabs Once the rim hardens, no more water can penetrate. The sand underneath the rim will be just loose sand and no amount of watering will penetrate then.

The basic process goes like this. First, you’ll need to lay your sub-base (normally a type of aggregate, like gravel), to ensure that you have a level, permeable base that any water can drain through. Then, once you’ve made sure the surface is even, pour out your concrete mix. Then, you’re ready to lay the paving slabs themselves. Plate compactor or garden roller: A plate compactor or garden roller is used to compact the MOT Type 1 and sharp sand and create a stable base for your slabs. Don’t forget that as well as the tools you need to hire, you’ll also need decent amounts of material like landscaping fabric, and hardcore materials too, like gravel. Over time, the sand beneaththe slabs can become compacted and settle, or even gradually erode away causing the slabs to become unsteady and potentially break. This can create an uneven surface and make it difficult to use the patio safely. It will also allow weeds to grow between the slabs. While creating a patio on sand can be a cost-effective and relatively easy way to add outdoor living space to your home, it is important to be aware of the limitations of this approach.

Everything about never seeing a weed on your patio again is ALL to do with how well you prepare. Following this guide will give you the best possible experience through this project. So let’s get started! Creating a patio on sand can be a cost-effective and relatively easy way to add functional outdoor living space to your home. However, it is important to approach the task with the right tools and materials, and to be aware of the limitations of this approach. When your patio or driveway was poured, chances are that the professionals installed a joint expansion system. Many times, an asphalt-saturated fiberboard or felt was used. But that material decomposes. You can fill large gaps in between patio pavers (aka pointing) with regular sand, a DIY mix of concrete and sand or polymeric sand. Filling Gaps Between Paving Slabs
