pihalaatat

Pihalaatat are outdoor paving slabs used to cover ground in residential yards, terraces, and pathways. They provide a durable walking surface and are typically installed on a prepared subbase to ensure stability and drainage. The term is commonly used in Finland and other Nordic regions.

Pihalaatat come in a range of materials, with concrete being the most common, along with natural stone such as granite, limestone, and basalt, as well as clay brick, porcelain, or composite options. Sizes typically vary from about 300 by 300 millimeters to 600 by 600 millimeters, and thicknesses range from around 40 millimeters for pedestrian areas to 60–80 millimeters for driveways. Finishes include smooth, brushed, tumbled, or textured surfaces to influence appearance and slip resistance.

Installation usually requires a well-prepared base consisting of a compacted subbase of crushed stone or gravel, followed by a bedding layer of sand or fine aggregate. Pihalaatat can be laid in a dry-lay or mortar bed, with joints filled using sand or polymeric joint material. In larger installations, expansion joints may be inserted to accommodate movement and prevent cracking. Proper drainage and, where necessary, edging to contain the surface are important considerations.

Climate and maintenance considerations are important in Nordic settings. Frost resistance is essential, and permeable options may be used to improve drainage and reduce runoff. Regular maintenance includes cleaning, weed control, occasional resealing or re-sanding, and replacing cracked slabs as needed. Pihalaatat offer a versatile, long-lasting option for outdoor spaces with various textures, colors, and patterns.
