Water-washed stone is a construction technique that has been increasingly used in recent years. Its essence is quite similar to the water-washed stone of the 1960s. While it's more challenging to apply on walls, quality is relatively easy to ensure. For ground applications, the difficulty is not significant, but cracks and localized settlements are prone to occur. Therefore, the foundation design and construction must ensure the stability of the subsoil. If necessary, reinforced concrete foundation pads should be used. Additionally, it is generally recommended to set them at intervals of 5 to 6 meters.Settlement joint。

Construction Requirements
Natural stone washed in its original colorCementStir and mix thoroughly, slag cement with a fineness modulus of 32.5 or higher, or ordinary portland cement.
2, Optimal particle size is 5-8mm, with silt 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.

OthersWashed Stone - Cautionary Measures

The cement grade used in washed stone typically ranges above 425.

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

All pebbles are fully coated and patched; large-area construction can now 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 period of time due to water washing.

The outdoor temperature during construction should be above 5 degrees Celsius to ensure that hollowing and detachment do not occur.

Materials for washed stone:

Spec: 4~6mm rounded sandstone (no sharp edges), Brand No. 425 Silicate White Cement (same batch), Pigments (any color), Wash-protected agents, etc. auxiliary materials
