The sand is simply pushed out of the joints. This is why we don't recommend using polymeric sand on extremely narrow joints. Similarly, too-wide joints can lead to washout, because they allow too much water flow during the activation process.

Will paver sand wash away?

Sustaining their beauty requires little work. However, since pavers are exposed to various elements such as rain and wind, the joint sand between pavers may get washed out overtime. Occasional washing can also cause the joint sand to corrode. This compacted sand plays an important role as it locks the pavers together.

Does polymeric sand let water through?

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 you tamp sand before laying pavers?

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.

How much will pavers settle after compacting?

Here's why: dirt shrinks by 30% when compacted. That means, if you backfill with dirt, your hardscape will settle 30%. This becomes an issue because, if you backfill with 10″ of dirt, your pavers will settle around 3″ over time. However, if you properly lay a gravel base, you'll essentially eliminate settling.
