Water-washed stone is a construction technique that has become increasingly popular in recent years. Its essence is quite similar to the water-washed stone technique of the 1960s. While the difficulty in wall construction is greater, quality is more easily guaranteed. Ground construction is not too challenging, but it is prone to cracking and localized settling. Therefore, the foundation design and construction must ensure the stability of the subsoil. It is necessary to use reinforced concrete foundation slabs. Additionally, it is generally recommended to set them at intervals of 5 to 6 meters.Settlement joint。

Construction Requirements
1. Washed stone is all in natural colorCementStir and mix thoroughly, slag cement with a fineness number of 32.5 or higher, or ordinary portland cement.
Particulate size of 5-8mm is recommended, with clay content not exceeding 1%.
3. Prior to large-scale application of water-washed stone, a sample should be made to determine the mix ratio and construction technique.

The cement grade used in washed stone is generally above 425.

2. Upon arrival at the site, the gravel must be inspected to ensurepebblesMinimal color variation, low impurities, and full grains.

3. After all the pebbles are coated and patched, large-area construction can proceed.RollerFlatten and compact

The color powder added to the cement is a UV-resistant powder to prevent the color of the stone pavement from fading after a long time due to water washing.

The outdoor temperature during construction should be above 5 degrees Celsius to prevent hollowing and peeling.
