How to Repair Sinking Patio Pavers

Do pavers hold moisture?

Landscape pavers that hold water indicate erosion of the base material under the pavers. Even the most meticulously installed patios are prone to settling over the time. As the ground shifts and rain washes away the base material, small pits form in the patio, providing space for water to pool.

Why is my patio sinking?

Is paver base better than gravel?

The only significant difference between gravel and paver base, is that the sharper edges of paver base mean it can lock together more effectively than gravel when packed down under the sand and pavers. However, this does not negate the use of gravel if you tamp it down well enough.

Can you lay pavers on just sand?

Laying pavers on sand base follows the same steps as laying them on soil base, but you'll be adding a layer of coarse sand, road base, or polymeric sand first. Rake the sand to even it out and use a plate compactor to make your sand base solid so you have a firm, stable base.

What causes pavers to lift?

Loose Paver Tiles

As the sand settles beneath the pavers, it can cause the bricks or tiles to shift and become loose.

It also allows water to permeate through, whereas polymeric sand only lets a small percentage of water to pass through. Since this product allows such a large amount of water to pass through, it is best used in applications where an open graded base is installed that allows water to pass through.

Do concrete pavers absorb water?

The stone or sand underneath the pavers filters the water to the soil below, thus watering the ground. These pavers absorb water much in the same way as grass, dirt, or any other outdoor ground would. Because of this, any water that falls on your pavers is able to easily drain to the soil below.

Does block paving absorb water?

Permeable or Porous Hard surfaces

Porous asphalt, concrete and block paving either allow the water through the material or around the edges of the blocks. They have to be built on a porous sub-base. This is a very durable surface with will require a minimal amount of maintenance.
