The CST Warranty

CST provides a 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.

Our 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.


EFFLORESCENCE: Efflorescence, is 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.
