Maximize the strength, stability, and durability of a backyard patio by filling the spaces in between the pavers. Sand and grout are common materials used to lock the pavers in place. Between these two options, sand is the best choice for six key reasons.
What are grouting options?
Using grout to fill the spaces between the pavers may not enhance the appearance of the patio but it does offer numerous benefits. These include protection from the elements and water damage. Grout holds the pavers in place and extends the lifespan of the patio.
The easiest type of grout to install between pavers is cementitious-based slurry grout. It is a cement-based mortar that, when wet and flowable, is poured over the pavers to fill the joints quickly. Because it is rapid-setting, it’s essential that it does not remain on the surface of the pavers.
Single-part polymeric compounds are a second type of grout that may be applied to low-traffic areas, like patios. Consisting of resin, this grouting option is fast and easy to use. However, for a stronger chemical reaction, two-part epoxy resin is recommended; though pricier, it withstands heavy loads.
A fourth option for homeowners is exterior tile grout. A dry, cement-based powder is combined with water to produce a semi-liquid grout material. Traditional mortar, the fifth grouting option, is still used today by contractors; it consists of four parts sand mixed with one part cement.
Why is sand a better option to fill paver gaps?
While grout may be a solid choice for certain applications, it is not advisable for use in between patio pavers. A number of reasons make sand the better choice, especially upon considering the various factors that apply to outdoor use.
1. Adjusts to Ground Movement
Firstly, grout, as a hard material, can crack during ground movement. The Midwest endures four seasons, from temperate springs to harsh winters. The freezing and thawing of the seasons can cause the ground to shift, thereby potentially cracking the patio grout. Sand, however, adjusts accordingly.
2. Offers Better Drainage
Heavy rainfall is common in some geographical areas, like the Midwest. Sand offers better drainage than grout. Water should be able to drain or be diverted quickly to prevent staining from debris. Sand allows rainwater to seep through it and helps preserve the structural integrity of the patio.
3. Cost-effective
Cost is a major factor in the choice of material used to fill patio paver gaps. Sand is generally cheaper than grout. However, it is important to use polymeric sand, which is more expensive than traditional sand. This is due to its polymer content, which improves its resilience.
Polymeric sand consists of various fine sands as well as additives. A strong bond is created when the sand is mixed with water, making it the ideal material to apply in between patio pavers. The Interlocking Concrete Pavement Institute (ICPI) endorses the use of polymeric sand.
4. Deters Weeds and Pests
Polymeric sand is also a weed and pest deterrent. Weeds, like dandelions, and grass cannot take root in polymeric sand. Similarly, pests, such as ants, are unable to burrow down the gaps. As a result, the patio pavers remain tidy and beautiful in appearance.
5. Easier to Apply
Sand is easier for homeowners to work with than grout. The ease of application makes it simple to resand the pavers with more polymeric sand when necessary. Refilling the gaps may be required only after 10 or more years when using polymeric sand, as it stands up well against erosion.
6. Low-Maintenance
Dealing with cracked grout requires more maintenance than simply re-sanding a patio. Homeowners who face cracked grout cannot simply patch the damaged areas. They must remove the grout and replace it. On the other hand, as mentioned, sand can be poured over the eroded areas to refill them.
Whether sand or grout, a durable material is necessary to support the pavers to prevent them from sliding against each other. Grout is recommended for high-traffic areas, like driveways. But for less-stressed areas, like patios, polymeric sand is the ideal choice for filling the gaps in between pavers.
The advantages of sand over grout are many, as mentioned. Adjusting for ground shifts, improved drainage, minimal cost, and reduced maintenance make polymeric sand the preferred material for installing in between patio pavers and keeping the patio stable over time.
Installing polymeric sand is an easy DIY task for handy homeowners. As the last step in the patio installation process, the sand is swept into the paver joints with a push-broom. Once the polymeric sand fills the gaps, spray with water for 10 minutes to activate it.
