Standing water weakens pavers, leading to chips, cracks, and even erosion. During colder weather, water that gets into these cracks and crevices can freeze, causing cracks to expand and worsen. To prevent pavers holding water, you want to invest in draining the pavers.
An influx of water that sits for a long period of time can damage your paver surfaces by weakening the cracks or chips already present. If your pavers are already loose, they may collapse. Flooding can also lead to erosion when soil and rock are transported and deposited into the area.
Pavers are permeable and are laid with small spaces in between them. These features allow water to run through them and back into the ground below instead of sitting on top, like it would with asphalt or concrete.
In case of bad weather, you will again face two options: If there is a huge downpour, it's best to postpone the process. Sand will surely get wet and wash out of the joints, so it is best to reschedule and start from the beginning. If there is light rain, you'll most likely have nothing to worry about.
If you have a paved driveway, or even along paved walkways and patios, sloped trenches can be dug up and filled with gravel to allow water to drain and run off into. This is great for two reasons. One, water runs away from the paved area, preventing flooding and water pooling up.

Initially, some water will seep into the joint sand for the first few weeks but soon silts and dust in the air will fill any voids and water will then shed off the paver surface just like any other pavement.
Therefore, keeping track of the weather can help you avoid sealing before impending rain. If a storm does occur before sealant application begins, consider waiting at least 24 hours until the dampness evaporates. If the pavers are wet due to a pressure wash, allow them at least 24 hours to air dry.
A paver installation requires a dry weather, as dry as possible. Installing pavers involves a lot of digging and a lot of sand, both things that don't go very well with rain. The digging part of the project is actually its most important part, as it is what will determine the longevity of the installation as a whole.
Can Excessive Rain Damage Your Pavers? There are a few different issues that heavy rain can cause to driveway pavers. The most common cause of damage like this occurs when water is able to build up beneath the pavers on your driveway.
Decreased Drying Time: Properly sealed pavers do not allow water to absorb inside them. This significantly reduces drain time. Pavers that dry more quickly, are much less likely to support mold and algae growth or develop efflorescence.
Theuse of polymeric sand increases the durability of the entire surface of the landscaped area. This minimizes the opportunity for water to seep below the surface of the interlocking pavers and into the sand and/or crushed stone foundation below.
Acidic cleaners: Harsh, acid-based cleaning products and stain removers can damage the seal and finish of your concrete pavers. Bleach: This alkaline solution may be effective for other household uses, but it can discolor concrete pavers that have been colored or stained.
Pavers Sinking in Areas
In fact, a paver patio that is sinking in areas very likely might have a drainage problem that was left unaddressed prior to construction. This issue will need to be addressed and corrected and then pavers will need to be re-laid.
Solution 1: When pavers aren't installed deep enough or at an even thickness, they can become uneven. In addition, soils that have a lot of clay tend to hold more water than soils that are primarily sand. When the soil holds additional water it tends to expand more when the ground freezes, which can push the pavers up.
Pavers can either be laid directly onto existing concrete permitting it's in good condition, or they can be set onto wet concrete and as it dries, it fixes the pavers to it.
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.
Never Too Late to Seal Pavers
It's always best to seal soon after a new installation. But, our proven system of repairing, cleaning and sealing will also bring back the original luster to old, dirty and fading pavers. Sealing is the final step in a comprehensive process.
Efflorescence is also known as calcium hydroxide or free lime. The phenomenon of efflorescence occurs when water soluble salts migrate to the surface of the paver with the help of water (i.e., condensation, rain).
The best way to prevent sand from washing from underneath pavers is to rerout or pipes any water coming from roof gutters or runoff and directs it in to a drywell or pipe it to the street . paving stone joints have to be filled and paving stones have to be vibrated after installation.
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.
Your bedding sand is a crucial aspect of your entire hardscape. Bedding sand helps your stones settle firmly into the base and stay-in-place; it also serves as a leveling layer to even out any minor discrepancies in the gravel base and the manufactured product.
Try permeable pavers
Permeable pavers are a great option for ensuring that you have adequate drainage for your pavers. You can even use a strip of permeable pavers as a type of french drain at the bottom edge of your driveway, along a fence line, or next to your house.
