One of the most common concerns our Lennar homeowners share with us involves the appearance of small cracks, chips, discoloration, sinking, or other movement in pavers or flatwork. Areas where you might notice these occurrences include concrete walkways, driveways, patios and some floors. Cracks and chips are common and are caused by normal shrinkage, expansion, and contraction of the materials used in flatwork. Sometimes, control joints are included in concrete flatwork. These joints are designed to control where the natural cracks will occur, rather than allowing the concrete to crack randomly.
While cracks are normal, you should inspect flatwork surfaces on a regular basis to stay alert to any changes. If you notice any cracks, you should seal them right away using the appropriate caulk. Instructions for use should be located on the tube of caulk. Using the appropriate caulk to seal cracks will help prevent water from seeping beneath the flatwork, causing more serious damage, such as heaving or extensive cracking, over time.
When you clean your flatwork or pavers, use a traditional broom or a leaf blower, rather than water, as water can leak under the surface and cause damage. Flatwork and pavers can also be damaged by harmful compounds used during the winter, such as salt and other deicing chemicals. The components in these products can cause damage like pocking or chipping in your concrete surfaces. Even trace amounts that stick to your tires can cause damage to your driveway and garage, so keep an eye on these surfaces. If you notice this type of damage occurring, make sure you provide proper protection as damage caused by these products is not warrantable and can be very costly to repair. All oil and gas spills should also be cleaned right away as they can damage or otherwise mar the surface.
Asphalt surfaces should be inspected regularly and cracks should be filled with an asphalt crack sealer and coating for protection.
Pavers require additional attention, so depending on the type you have, you may need to either use a sealant to provide protection or replace the sand in between each paver on a regular basis. We recommend verifying the maintenance requirements with your local Lennar Customer Care team to ensure that your pavers are properly cared for.
