You can prevent the pavers from shifting by adding a solid edge to your patio, like cement, plastic or metal edging. Once you do this, you can spread polymeric sand over the surface and sweep it into the gaps, so they can stay in place.
The sand used to fill in the gaps between pavers is necessary to lock each individual brick into place. This prevents the interlocking pavers from shifting and ruining the overall look of the paved surface. Once all the pavers are properly laid out on top of the sand bedding, cover the entire area with more sand.
These binders help to hold the paving stones in place and prevent them from shifting or moving. Polymeric sand is often used between joints in paving stones to improve the stability of the surface. It can also be used on its own as a paver base material.
Yes, pavers can shift and move over time due to various factors such as ground movement, poor installation, and dramatic temperature changes. In most cases, improper edging tends to be the leading cause of pavers shifting.
They're nestled on top of a bed of compacted sand. For the most part, they stay secure. But over time, the sand settles into the ground, making the pavers lopsided. Gaps in the sand underneath cause pavers to wiggle loose.
Joint stabilization – If you don't have sand in the joints, rain water or pool water will run between the brick paver joints, and wash out the base aggregate sand material your brick pavers float on, (usually a 1.5” – 2” sand base) making your brick pavers loose, wobbly, uneven, sunken in or even raised up in some ...
Polymeric Sand has many benefits, however, the biggest drawback is that it can be easy to mess up, especially if you don't follow the manufacturer's instructions.
Most experts recommend waiting for at least 24 to 48 hours before sealing the new pavers after installation. This gives the pavers time to settle and ensures that they're completely dry before being sealed. If you live in an area with a lot of rain or snow, it's best to wait even longer to seal the brick pavers.
Polymeric sand is the most popular and useful filler used under brick pavers. It is a mixture of fine sand, adhesive and is most widely used in paver joints. Typically, polymeric sand lasts for up to 10 years. But if you use high-quality polymeric sand, it can last for approximately 15 years.
Protect from rain for at least 12 hours. No sealer is required. Sand remaining on paver faces can create a slight haze after wetting. A minimum of 24 hours drying time is required prior to allowing significant foot traffic and 48 hours for vehicular traffic on the paver surface.

Hi, a good fix for loose slabs is to mix neat cement in to a paste, wet the back of the slab put some of the neat cement in the hole and lay the slab in and tap it down level with a rubber hammer, job done. Also the cowboy should of wet the back of each slab before laying then they would of stuck.
The most common cause is that your pavers have been laid on an uneven aggregate bed. This greatly affects the structural integrity of your patio, making it more likely to break down underneath the surface.
The basic rule of thumb is every 3-5 years. For film-forming sealants, you will be able to notice when the physical barrier is showing signs of wear. For non-film-forming sealants, you will begin to see a significant color change of pavers during a rain when the sealant is wearing thin.
Cementitious-Based Slurry Grouts. This type of paving grout is one of the easiest to apply between your patio pavers. This wet, flowable, cement-based mortar is poured across the paving slabs to fill the joints between the pavers quickly. This patio grout is much easier to apply than traditional mortar.
Polymeric Sand is great for stabilizing your pavers because it bonds so well. This becomes a problem though, if it is activated and then allowed to dry ON TOP OF instead of between pavers.
Can you apply polymeric sand twice? No, new product won't adhere to the old. You have to remove the old polymeric sand and then apply fresh product for the best result.
If your polymeric sand didn't harden up, it's pretty much guaranteed there's a moisture issue. If the joints remain wet after the installation, they will remain soft until they dry. So getting one initial complete drying "set" is very important to the long-term performance and lifespan of the product.
Unless your pavers are installed with the edges touching another solid surface (a curb, driveway edge or a wall), you should have edging installed along the whole perimeter. This way, your patio pavers will stay in great condition for much longer, without cracking, shifting, or lifting.
Before you begin laying pavers, prepare the ground. Ensure you have a root and rubble free compatible sand sub-base of at least 50mm thick. The sub-base should be roughly levelled and damped down before tamping down firmly with a hand or mechanical compactor.
A paver patio that has uneven pavers can create dangerous trip hazards. This is once again most likely due to a problem with the construction of the base. The ground might not have been compact enough to bear the weight of the pavers and the people on top of them, and therefore some have sunk or become uneven.
