Unilock's diverse line of stamped concrete products offer a an extensive selection of colors and styles and a number of unique textural surface treatments. Proportional unit sizing has also been maintained between many stamped concrete styles resulting in a paving system with an augmented level of function and design. The architectural advantages of interlocking stamped concrete pavements are readily apparent. With their small size, colour and shape variety, they offer a warmth and human scale that is difficult to achieve with conventional concrete and asphalt. They are a perfect complement to almost any architecture. Interlocking concrete pavers can be installed in a variety of patterns including curves, straight lines, intricate designs, and add vitality to almost any environment. |

The principal components of interlocking stamped concrete paver pavements include base materials, pavers, bedding sand, jointing sand, sealer, geotechnical fabric and edge restraints. Interlocking stamped concrete pavers are concrete units manufactured with high strength, dense portland cement concrete. UNILOCK pavers come in many sizes and shapes and in numerous colours to enhance the architectural flavour of the pavement. Contact UNILOCK for the full range of pavers and other paving elements available. The manufacturing of high quality stamped concrete pavers involves combining portland cement, coarse and fine aggregate and sufficient water to produce zero-slump concrete, which in turn is molded in, specialized manufacturing equipment under vibration and extreme pressure. Admixtures may be used to increase various engineering properties (strength, density) and reduce the likelihood of efflorescence and decrease water absorption. Normally, the paver units are constructed with spacer bars to ensure uniform, properly spaced joints and with chamfered edges to prevent chipping. |
Geotextile fabrics are normally not required with an aggregate or hot mix asphalt base. However, for a cement treated base, a woven geotextile fabric is recommended to prevent migration of bedding sand through shrinkage cracks which normally develop as the cement treated base cures. With inlays or overlays over existing asphalt or stamped concrete surfaces, a geotextile is also recommended. The fabric shall be turned up against edge restraints or structures to prevent sand from migrating into the joint between the pavement and the edge restraint. |
