Waterproofing for Grand Hampton Homes
Grand Hampton is a private, gated community in New Tampa, ZIP 33647, near I-75. Its villas and semi-custom estate homes, from about 1,500 to more than 5,000 square feet, sit among lakes, forests, wetlands and conservation preserves.
Newer homes are built to a higher standard, but they still sit on slabs on low, sandy ground beside water. When the rainy season fills the lakes and wetlands, the water table under the homes rises too.
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.
Newer Homes, Same Water
A newer home has a newer vapor barrier, but it does not change the ground it sits on. In Grand Hampton that ground is beside lakes, wetlands and preserves. Getting roof water and groundwater away from the slab early keeps a newer home dry for the long run.
The Water Around a Grand Hampton 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 at the slab edge after rain
- Soggy ground between the home and a lake or preserve
- Downspouts emptying into beds beside the foundation
- Efflorescence on the lanai or garage 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 Grand Hampton Homes
Perimeter Collection
A collection line along the foundation, built with clean stone, filter fabric and smooth-wall pipe.
Roof Water Tie-In
Downspouts piped underground into the system, so roof water never lands at the wall.
Sump & Pump
A sealed sump with a pump sized for Tampa storms, for lots too flat to drain by gravity.
Legal Discharge
Water sent to a storm inlet, street gutter or pond connection where the site and the community allow.
Slab & Wall Waterproofing
Where water has already reached the slab or walls, we seal the structure itself.
Documentation
Photos, scope and a lifetime transferable warranty for owners and future buyers.
From Inspection to Lifetime Warranty

Moisture mapping inside and out, plus the slab, walls and grades around the lot.

Roof water, groundwater, lake and wetland levels and where the water can legally go.

Grand Hampton Waterproofing FAQ
Do you work in Grand Hampton?
Yes. We work throughout Grand Hampton in ZIP 33647, including its villas and estate homes. We coordinate gate access and association review with you before work starts.
My Grand Hampton home is fairly new. Can it still get water at the slab?
Yes. A newer home still sits on the same low, wet ground beside lakes and preserves. Roof water dropped at the foundation and a high water table can push moisture into the slab in any home, new or old.
How much does foundation waterproofing cost in Grand Hampton?
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.
