Sealer is a product designed to maintain the look of both natural and manufactured stone (Interlock). However, if the sealer is not applied properly, it can lead to discolouration, and even a patchy, film like residual on your stone. Many sealer manufacturer’s recommend you should seal your natural stone, or paving stone every three years. If you require more information about the sealer, and sealing, please ask your sealer brand.
The reality is any type of salt or salt based ice melter may cause damage to your interlock or concrete. However, alternatives such as gritty sand, and, or, Kitty litter will act as an agent to create traction on the surface, but will not work as a melting agent.
Overtime your interlock may require a maintenance technique known as Lift and re-lay. This technique is useful for interlock bricks that come lose, or become unlevelled due to continual use. The lift and re-lay technique requires removing the damaged or unlevelled bricks, leveling off the base screening, sand, or gravel beneath, and re-laying or replacing the bricks. In order to create a seamless, undetected result, you will need to apply polymeric sand into the joints. You may consider calling professional to assist with this type of maintenance.
Before beginning any project around the home, it is extremely important to be aware of where water from the downspouts will flow. Water flowing towards the house can cause serious issues such as foundation corrosion or water finding its way into your home. Downspouts should be extended at least 6 feet away from your home where possible. They should also be converted under any walkways or high traffic areas using solid PVC pipe to reduce ice build-up in the winters, erosion from consistent water flow and tripping hazards.
Polymeric jointing sand is an effective solution when it comes to erosion control, weed inhibition, insect resistance and the overall surface response to movement. Polymeric sand joints will require maintenance every several years. Joints can crack over the years due to a natural process referred to as heaving. Ground heave is created by frost during the winters and consistent traffic over time. When significant cracks are observed, more sand can simply be swept in. At a certain point over the years the entire area may have to be completely power washed and re-sanded.
