Our Precious Stones are forever and so is our warranty

Techo-Bloc is proud to certify that our paving stones and retaining walls meet the latest industry standards effective in Canada and the United States of America. All Techo-Bloc manufactured Landscape products comply with and surpass all applicable standards set by the CSA (Canadian Standards Association), ASTM (American Society for Testing and Materials) and the BNQ (Bureau de normalisation du Quebec), acknowledged as the strictest in the world.

Techo-Bloc offers a transferable lifetime warranty on the structural integrity of all paving stones and retaining wall stones it manufactures. It covers any disintegration and/or decomposition of the above mentioned products resulting from natural causes and the abnormal deterioration of the surface due to the use of sodium chloride (NaCl) such as de-icing salt.

If products prove defective we will replace these units. Techo-Bloc’s responsibility is limited to its products only and not to costs related to the installation of those products. Techo-Bloc will honor this transferable warranty with a proof of purchase (invoice or delivery slip).

Warranty Details and Exclusions

Printed Color Swatches

Due to the inherent nature of printed literature and current digital media Techo-Bloc cannot guarantee specific color matching. The natural materials that we use in our paving stones and retaining wall products deliver a range of natural colors that closely match color samples, in catalogues, spec books, color swatch books and online photos. Comprised of natural ingredients, pavement units vary slightly in color batch depending on environmental conditions. Therefore, colors shown are approximate representations of standard colors and shouldn’t be expected to be an exact match. Final color selection should be made at your local dealer from stock product. Techo-Bloc always recommends immediately verifying the product and color upon receipt. If there are any discrepancies, contact your local dealer before continuing your project. Installation of the product constitutes its acceptance.



This warranty does not apply to efflorescence. Efflorescence is a naturally occurring process in all concrete products that sometimes appears in the form of a white powdery film on the pavement surface. It does not, in any way, compromise the functionality or the structural integrity of the product. Although efflorescence cannot be prevented, it will wash off over time or can be cleaned with an efflorescence cleaner. Techo-Bloc accepts no responsibility or liability for this condition.

Compactor and Snow Removable Equipment

Pavers with an embossed surface (high and low points) are more susceptible to scuff marks from vibratory plate compactors used in most concrete paver installations. Techo-Bloc recommends the use of a urethane mat between the plate and the paver surface when compacting. Contact your equipment supplier for more information about accessories for this purpose. Also snow removal equipment should have the proper spacing, bumpers, and rubber blade guards to protect the surface of the pavers. Techo-Bloc will not be held responsible for damage caused by the misuse of compaction or snow removal equipment, leaving scuff marks, or burns on pavers.


Proper Color distribution and Laying Techniques

Proper installation enhances the overall color of pavement. Pavement units should be selected from at least two pallets and then randomly mixed. This creates an attractive and subtle blending of color.


NOTE: This warranty does not apply to any breakage, chipping, or other deterioration that were caused from improper design or installation which does not comply with applicable codes, the ICPI (Interlocking Concrete Pavement Institute), NCMA (National Concrete Masonry Association) and recognized work procedures. Please visit or for more information on installation specifications. This warranty does not apply to any damage resulting from a natural disaster or from a deliberate and/or negligible act on the part of the purchaser, owner of the building, installer or any third party.
