Is it okay to use fabric designed to prevent weed growth in planting beds instead of geotextile?
No, this material is sometimes not as strong as geotextile and can tear easily. Q: Should limestone screenings or stone dust be used under the concrete pavers? What is recommended by ICPI? A: No. Most screenings and stone dust have too many fine particles that slow drainage and rut under repeated loads from tires. Sand made with crushed shells (common in Florida) shouldn’t be used either. Concrete sand is recommended. It’s the same sand mixed into concrete pavers and poured, cast-in-place concrete. Q: What is interlock? A: In short, tt’s the inability of a paver to move independently of its neighbors. It’s the locking of the pavers that causes loads to be spread over a wider area of pavers than where the load was applied. It’s the key to the strength of the pavement system. Q: Should I seal concrete pavers? A: Sealing is not essential in many applications but it offers some benefits like making spills and stains easier to remove. Liquid sealers are applied after the pavers are installe
