Level Up The Uneven Area With Grit Sand

NOTE* Before you begin to level up the area that has sunk with grit sand it may be worth investigating why the paving had sunk in the first place? If you are confident that it is not because of a broken drain or inadequate depth and strength of the stone sub-base,; you can begin to repair the; paved area.

Always use grit sand and not building sand when you lift and relay block paving. You can purchase grit sand with free home delivery here. The grit sand works because it supports your paving better and allows for a better drainage should you get a penetration of water into your paving block joints. Building sand will just become soggy and hold the water rather than letting it drain through.

Grit sand is available in small 25 kg bags or large 1 tonne bags, although if you need the 1 tonne bag you have serious problems with sinking and I would call in a paving expert to give your block paving an inspection. Grit sand wherever possible should be kept out of heavy rain. This stops one area of sand being water saturated and makes laying the sand easier and lighter.

Begin by using the straight edge again to judge the amount of grit sand needed to fetch the level up to the appropriate height that is needed to level the paving with the surrounding block paving, once you have leveled your paving.

Compact The Relaid Paving

How To Repair/Fix Sinking Block Paving Driveway Patio Stonemason Landscapes

It is important that any relaid block paving is compacted. But before any compaction of the block paving takes place you first need to sweep clean the paved area. This stops any debris such as small stones being vibrated down between the joints of the paving. If this happens it can distort the laying pattern and overall design of the driveway or patio.

Compaction should be done with a whacker plate or straight-edged timber & hammer. This should be done to the whole paving area 2 or 3 times. Particular attention should be made when compacting the edges of relaid paving. The paving edges need to match up to the existing paving that has not been relaid. It needs to be level to stop any trip points. Care should also be taken around sensitive areas such as walls , drains or inspection covers.

To compact the relaid paving you can use a large flat piece of timber that covers the area that has been relaid. Place the timber on the relaid block paving and firmly strike the timber several times with the hammer. Make sure you hit the wood and not the blocks. Lift the timber to check that the paving is level. Repeat until you are confident the paving has become firm and stable.

You should be, but as now you are here, you can consider half of your work is done. We are going to show how to keep pavers from sinking with some simple tactics in this article.

Most of the patios are made from brick pavers. These pavers are set in a basket weave pattern so that each and every brick fits perfectly with the ground. Once the sand is leveled perfectly, the workers start to lay them following the pattern. Then fill the gaps with additional sand around them. Although this is an ordinary process of establishing pavers and every contactor will follow these processes, the sands can wash away with a small or heavy amount of rain. Heavy rain also develops low spots, and due to all these situations, pavers usually sinks down. No matter what the reason is, the problem is yours, and it is hampering the overall look of your backyard. So, it is up to you to solve this problem. Lets how you can do that.

Add Crushed Stone Dust

Crushed stone dust or sand is used directly under the pavers because it can be levelled and compacted easily. The stone dust can be purchased in bags or in bulk.

Using a shovel, spread the stone dust in the area you’re working. It only needs to be roughly level. Since my steps had existing concrete borders, I was able to use them as a reference. By filling the stone dust to a certain point, then tapping down a paver , it was fairly easy to find just the right amount of stone dust to raise the pavers back up to level. For most of the steps, I had to add more towards the front of the step since that is where the pavers had sunken the most.

If you’re filling a large area, use a long, straight 2×4 or a bubble level to help spread and level the stone dust. You may want to get some help from a second person.

  • If you didnt use spacers when installing your pavers to make uniform spaces, then there is too much space between them. Close-tight pavers arent just for looks: its to make the whole surface stronger and stabler.
  • Did you compact the sand base? If you didnt, then a shifting base could have dislodged your pavers.
  • If you skimped filler sand, then theres not enough sand to keep the pavers in place.
  • Pavers usually start wearing around the edges when theyre old enough. This can be fixed with a proper edging installation, though.
  • Are your pavers inclined? Do they let water flow smoothly? If theyre not, they will absorb moisture and get damaged.

    How Do I Fix Them

    1. First step is to lift the old pavers using a trowel, flathead screwdriver or something that is sturdy and has a thin straight edge. As gently as possible try to pry up the end of each paver. Sometimes the use of a second straight edge will help in this process. Use a rubber mallet or a piece of wood to hit on the pavers if they are wedged in to tight, in order to loosen them up. Once you have them up take the time to clean any excess sand around the edges to make the re-installation process go a little smoother.

    2. Use a straight edge to scrap out the now exposed area in order to level it out the best you can. Apply more concrete sand or bedding material in the area to bring the level to no more than 1/4″ above the bottom of the other pavers still in place. Use a straight edge or some sturdy pipe if possible to ensure the sand is laid evenly.

    3. At this point you can relay the pavers in the same pattern as before. Once the pavers are in place you can use a rubber mallet to pound them down until level with the existing pavers. Leaving the sand or bedding material no more than 1/4″ above the bottom of the existing pavers in step 2 ensures that when you pound them with the rubber mallet that they don’t go down to far.

    4. The final step is to apply the jointing sand. Polymeric sand is recommended to ensure the joints stay sealed and lock together. Be sure to follow the manufacturer’s installation steps to be sure that is correctly done.
