A paver patio is one of the best-looking parts of a home — until the joint sand washes out, the edges sink, and the soil around it starts disappearing. Erosion is one of the most common questions the DuraSeal team gets from homeowners in North Carolina, South Carolina, Georgia, and Florida. Here is how to stop it. (We are rated 4.9 stars from 450+ reviews.)
What Actually Causes Paver Erosion
Rain hits the patio, sheets across it, and has to go somewhere. Southeastern downpours move a lot of water in a short time, and where it concentrates, it carries soil and joint sand with it.
Slope, Drainage, and Joint Sand
Pavers have to pitch away from the house so water does not reach the foundation. That same pitch aims a steady stream at your beds and lawn, so plan where it lands: a drain, dry creek bed, or gravel edge beats bare topsoil. Solid slabs shed nearly everything; paver joints let some water through, which is why the sand in those joints is the first thing to wash away.
Practical Steps That Help
- Keep the grade pitched away from the house, and give the runoff a place to go.
- Extend downspouts past the patio instead of onto it.
- Use edge restraints so perimeter pavers cannot creep outward.
- Refill joint sand before the gaps get deep.
- Plant or mulch the downhill edge so bare soil is not exposed.
The Pavers Themselves Erode Too
Concrete pavers are porous. Unsealed, they absorb rain, spills, and irrigation water, and every freeze-thaw swing expands that trapped moisture and works the material apart. Over years that shows up as spalling faces, rounded edges, and hairline cracks — erosion of the pavers, not just the soil.
How DuraSeal Protects Your Patio
DuraSeal is not a stain, a paint, or a glossy topical coating. It is a professionally applied penetrating sealer that bonds inside the paver, blocking water infiltration from within. Because there is no surface film, there is nothing to peel, cloud, or wear off under traffic — and it is backed by a 25-year transferable warranty instead of a reseal every couple of seasons.
Most residential projects fall between $2,000 and $6,000 depending on square footage, condition, and prep — see our pricing page.
