Waterproofing for Westchase Homes
Westchase began in 1991 and grew into one of the largest master-planned communities in Tampa, with roughly 11,000 homes spread across about 30 neighborhoods, the Westchase Golf Course and the walkable streets of West Park Village. Close to a square mile of it is water.
Nearly every home was built on a concrete slab close to grade, on flat, sandy ground beside a lake, pond or retention area. In the summer rainy season the ground fills, the water table rises and the slab edge is where the water stops. After 25 to 35 years, original vapor barriers and grading have also aged.
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.
Thirty Years on the Water
The first Westchase homes are now more than 30 years old. Landscaping has grown in, beds have been raised against the walls, and the original slabs have spent three decades beside ponds and lakes. Wet floors and cupped wood in these homes usually start at the foundation, not the plumbing.
The Water Around a Westchase 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
- Water standing along the slab or between homes after rain
- Landscape beds built up against the stucco
- Dark, damp stucco at the base of the wall
- Soggy ground at the lanai or pool deck edge
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 Westchase Homes

Legal Discharge
Water sent to a storm inlet, street gutter or pond connection where the site and the community allow.
Slab & Wall Waterproofing

Westchase Waterproofing FAQ
Do you work in Westchase?
Yes. We work throughout Westchase in ZIP 33626, including West Park Village and the neighborhoods around the golf course. We coordinate any association review with you before work starts.
Why do so many Westchase homes get wet floors?
Most homes sit on slabs close to grade beside lakes and ponds, on sandy ground with a shallow water table. As the original vapor barriers and grading age, groundwater and roof water reach the slab, especially from June through September.
How much does foundation waterproofing cost in Westchase?
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.
