CST provides a transferrable lifetime warranty on the structural integrity and deterioration (due to natural causes) of its paving stones and wall systems to the original purchaser of the product. Proof of purchase is required.

All products must be installed following CST and versa-lok® installation guidelines. If any paving stone or wall units are found defective CST will replace the units. CST’s responsibility is limited to the products and does not extend to the cost of installation or shipping. Due to the very nature of concrete products, we cannot guarantee the exact color match of the replacement units. CST prides itself in manufacturing its products to the highest standards.

You must register your product within 60 days from installation to activate your transferrable lifetime warranty.

CST products are made from natural materials which have variations in color and shade. The color photos in this brochure were prepared with great concern for accuracy. However, reproductions do not always precisely convey the color and texture of the actual product. We highly recommend that you visit an authorized CST Dealer’s display to make your choice.


Efflorescence, a natural and common occurrence in many concrete products. Efflorescence occurs when natural salts come to the surface and leave behind a white deposit that can normally be brushed off. Efflorescence is not a product defect therefore CST accepts no liability for its occurrence. Efflorescence will usually weather away with time.
