Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Alton home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel.

If your home has cracked concrete steps, pool decks, patios, or other slabs, then NexusPro is the right solution. NexusPro repairs concrete cracks and joints and is ultra-durable, so it will withstand UV rays, extreme weather, and more.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro. SealantPro further protects your concrete by bonding with it to guard against oil, gasoline, liquids, and other debris. In just one coat, SealantPro extends the life of your concrete by 3 to 5 times overall. 

Call us today to learn more about our proven concrete leveling, cracked concrete repair, and concrete sealing techniques.

Job Stories From Alton, ON
Unreliable Sump Flooded This Basement Regularly! Alton, ON

A customer in Alton, ON, had a water issue in their basement. They had a foundation crack on the back wall of the basement and an untrustworthy sump system with no battery backup. This was a problem because the crack was leaking water into the customer’s basement and the sump could not keep up with the amount of water it was receiving. When the power went out, the customer’s water levels rose above the floor level! This situation affected the customer’s quality of life, peace of mind, the value of the home and mold was even beginning to grow!

The customer called Clarke Basement Systems and booked an appointment with our Waterproofing Specialist, Ben Wallis. Ben isolated the issue and developed a solution to keep the basement permanently waterproofed. Installation technician Mark Dougherty installed one FlexiSpan™ wall crack repair inside of the basement, which is permanent. Additionally, the sump system was replaced with one Zoeller™ Sump Pump and an UltraSump™ battery backup. The wall crack repair system seals the crack and provides a secondary drainage strategy – groundwater can never get to the floor again for the lifetime of the home. The Zoeller primary sump pump removes water from the sump liner and when the power is out the UltraSump™ battery backup system takes over and removes the water from the sump liner. 

The customer was satisfied because the FlexiSpan™ wall crack repair system stopped the leak. It also carries a lifetime, nationally-backed warranty that is fully-transferable with the title of the home. Additionally, the sump equipment installed gave the homeowner peace of mind that the new equipment could keep up with the amount of water flowing into the sump system and the battery backup would take care of business when the power goes out.
