Waterproofing for Cory Lake Isles Homes
Cory Lake Isles is a guard-gated community in New Tampa, ZIP 33647, built around Cory Lake, with a private beach, clubhouse and pool. Many homes sit directly on the water, and nearly all of them are built on slabs.
A lakefront lot is beautiful, and it puts the water table right under the house. When the lake rises in the rainy season, the groundwater under the yard and the slab rises with it.
We design concealed systems for these homes: collection at the foundation, roof water piped underground, sumps sized for summer storms, and waterproofing where water has already reached the slab.
When the Lake Rises
In a lake community, the water table under a lakefront home tracks the lake. After a wet summer, groundwater can sit just below the slab for weeks. That steady pressure, not a single storm, is what pushes moisture up into floors.
The Water Around a Cory Lake Home
Why homes built on slabs close to grade in Tampa see so much water at the foundation.
623 gal
runs off each 1,000 square feet of roof. A 3,500 square foot roof sheds more than 2,000 gallons in a single one-inch storm.
49.5 in
falls in an average year, and about 61% of it comes from June through September.
~4 in
rise in the water table for every inch of rain once the sand is soaked, so pooled water has nowhere to drain.

Is Water Reaching Your Slab?
Around the Home
- Soggy lawn between the home and the lake after rain
- Water standing at the slab edge or lanai
- Dark, damp stucco at the base of the wall
- Efflorescence on the pool deck or lanai slab
In the Home
- White crust on tile, grout or concrete (efflorescence)
- Cupped wood floors or lifting tile
- Musty baseboards and swollen trim
- Damp garage or laundry room slabs
If you see signs inside, water is already under the slab. That calls for waterproofing, not more landscaping.
How We Protect Cory Lake Isles Homes

Legal Discharge

Cory Lake Isles Waterproofing FAQ
Do you work in Cory Lake Isles?
Yes. We work throughout Cory Lake Isles in ZIP 33647, including lakefront and interior homes. We coordinate gate access and association review with you before work starts.
Do lakefront homes in Cory Lake Isles need waterproofing?
Lakefront homes are the most exposed, because the water table under the yard rises with the lake. When moisture reaches the slab, a collection system and slab waterproofing keep it out of the home.
How much does foundation waterproofing cost in Cory Lake Isles?
Every system is sized after an inspection. A typical collection line with a sump pump starts around $9,000 plus the electrical, and full perimeter and slab systems on larger homes run higher.
Is the work warrantied?
Yes. Our systems carry a lifetime warranty that transfers to the next owner of the home, which buyers and their inspectors look for.
