Late Winter and early Spring weather can cause severe damage to walkways within the landscape. This is due to water accumulating under the walk and expanding under freezing temperatures at night, causing the walk to shift upwards. There are a few things we can do to prevent this from happening.
The first is to use proper installation materials and practices. The base material should be one that compacts well while allowing for adequate drainage. We recommend a natural 21AA aggregate, to a minimum depth of 6 inches, with a small sand layer on the top. In heavier soils a greater depth should be used to allow for better drainage.
We should also take measures to move water away from the walk. Direct roof and sump drains to other locations by rerouting them to and area that will drain away from the walk. The surrounding grade should slope away from the walk as well allowing for any water on the surface to easily exit the area.
Concrete walks usually crack when this happens and cannot be repaired back to new conditions. Brick pavers can be lifted and relayed to once again make a beautiful walkway. As mentioned, the key is to prevent water from freezing under the walk. If you have issues with your walks, whether they are concrete or brick, feel free to contact us for help at anytime.
