A home in Unionville, Ontario, had a problem located in the cold cellar beneath the front porch. Water was seeping in through a crack in the front porch slab, and the slab was not stable. This was a problem because the house smelled very musty due to the leakage, and nobody could stand on the front porch because it was unstable. The home was a daycare facility and children are coming in and out of it every weekday. The health and safety of the children was at stake.

The owner contacted Clarke Basement Systems for a solution. Jose Martinez and the crew came in and installed CleanSpace® wall membrane on the walls to capture any water and moisture. They established a WaterGuard® to collect any water seepage and push it away from the home, and SmartJacks™ were used to make the repairs and stabilize the porch slab.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Unionville 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. We also offer professional installation of LintelLift to repair and support sagging, cracked garage lintels.

Job Stories From Unionville, ON
Crawlspace Encapsulation System in Unionville, ON

Homeowners in Unionville, ON, were having water seepage issues in their cold room. Water was leaking from the walls and the ceiling, where they kept their storage.

They had to move the storage to the basement, which was a considerable inconvenience and continuously got in their way. They knew that to reclaim their cold room, they needed to fix their water leaking issues!

They contacted Clarke Basement Systems and set up a free inspection with System Design Specialist, Ron Monk.

Ron Monk inspected the house and concluded that we would need to install our patented Crawlspace Encapsulation System which included a SmartSump®WaterGuard® and CleanSpace®.

Once Ron had come up with the perfect solution, the homeowners were ecstatic to move forward with the process. Soon after, Installation Foreman, Jose Martinez and his team attended the home to install our patented products.

Jose Martinez had removed all shelves, wall and ceiling materials in the cold room to gain access to the concrete walls. Then they installed our WaterGuard® drainage system, which connected to our SmartSump®, as well as our CleanSpace® Wall Membrane System.

Once the work was complete, the homeowners were relieved to be able to use the cold room again. They could now store their belongings and not have to worry about any future water seepage issues.

Stop Water Seepage in Aurora, ON

Mark B. and his family recently moved into their new home in Aurora, ON. Once they got settled in and they were excited to start renovating, Mark noticed that the basement was damp. To him, this was going to be a HUGE issue, as he wanted to renovate his new home's basement as soon as possible to create more living space. In his previous home in Unionville, ON, he had similar issues with water seepage. Clarke Basement Systems fixed those issues, so he knew he had to call us again.

 

Our System Design Specialist, Chris Luke fixed his home's water seepage issues in Unionville and was called again to diagnose the issue at his new home in Aurora. After inspection, Chris noticed that the area of concern was the back wall. Water was seeping through the foundation walls and pooling on the basement floor. Chris put together a plan that would not only fix the issue, but also give Mark the peace of mind of knowing that he could renovate his basement without damaging any new additions. The plan consisted of a ThermalDry™ Wall membrane that would drain all the wall's water into our patented Waterguard® trench system. All the water would then flow from the Waterguard® trench perimeter and into our patented SuperSump® Sump Pump. This sump system would then pump all the water out of the basement and away from the house, leaving it dry. The ThermalDry™ Wall Membrane not only funnels the water to the Waterguard® system, but it also improves comfort and energy efficiency by reflecting heat back into the basement.

 There's no doubt that Mark and his family can now enjoy a dry, healthy basement and begin their renovations.

Damaged Concrete in Unionville, ON

Our customer had removed a large tree from their property causing their concrete walkway to settle. The roots of the tree had been pulled out creating large voids under the concrete weakening the soil and allowing for settlement to occur. Our customer was concerned that the sloping pavement could pose a severe trip hazard and would cause water to pool at the foundation of the home.

 

A meeting was set up with Project Lead, John DiNicolantonio. He proposed to inject Polyurethane. Our polyurethane is injected beneath the settled concrete and compresses the loose soils, lifting the slab. Foreman Kyle began by drilling dime-sized holes through the concrete and then inserting the Polyurethane.

 

We offer an affordable alternative to fix sunken and settled concrete without the need of replacing or ripping it out. Our customer is pleased we were able to correct the slope of the walkway and remove all of the trip hazards.
