Before After
80-Year-Old Leaky Foundation in Penetanguishene, ON 80-Year-Old Leaky Foundation in Penetanguishene, ON

The original basement was dark and damp with a lot of water coming in for almost 80 years. We installed CleanSpace on the walls, a WaterGuard® Below-Floor Drain around the whole perimeter of the basement and a SuperSump® Premier Sump Pump System with an UltraSump® Battery Back-Up System to collect the water and get rid of it. To finish the project we installed the SaniDry™ Sedona dehumidifier to keep the humidity low and keep mould away.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Penetanguishene 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.

Foundation leaking into garage. need fixed asap.
Project Location: Penetanguishene, ON
I have a damp/smelly crawlspace that is currently "sealed" with plastic liner but this does not stop water going into the dirt and is not stopping the smell from coming up into the house. There is a sump pump installed but I dont think its installed in the right location - not sure its doing its job. About 50% of the house is surrounded by a garage or is above ground. The house is only 700sq feet so the exterior excavation/sealing is a fairly small area. The front of the house has concrete steps and a flowerbed that will need to be demolished to get to the block wall.
