Drainage and Waterproofing Clearwater
Drainage and Waterproofing Clearwater, FL from Foundation Masters, LLC provides homeowners, condo boards, and commercial property managers with engineer-designed solutions to stop flooding, water intrusion, and soil erosion. As the first engineering firm to pioneer the waterproofing industry in Florida, we deliver permanent systems backed by a lifetime transferable warranty.
Why Drainage and Waterproofing in Clearwater Is So Critical
Clearwater sits on the Pinellas Peninsula along the Gulf of Mexico and Intracoastal Waterway, with shallow water tables (often just 2–6 feet below grade) and minimal natural slope. Annual rainfall averages 50–60 inches, and summer storms can drop ~3 inches of rain in an hour. High tides and coastal surges can push the water table inland, reducing infiltration and loading slabs with hydrostatic pressure.
Florida has no statewide waterproofing code (only an elevation rule requiring finished floor slabs to be 12 inches above grade). Many Clearwater homes were built at or near grade, so when groundwater rises after storms, moisture penetrates slabs, damages finishes, and accelerates structural deterioration.
Check your flood risk on the FEMA Flood Map Service Center or the Pinellas County Flood Information Portal.
Signs You Need Drainage and Waterproofing in Clearwater
- Standing water or soggy yards after storms
- Buckled wood floors or tile popping from slab moisture
- Water stains or efflorescence along baseboards and walls
- Mildew odor or visible mold near slab edges
- Driveway or parking lot flooding that drains slowly
Our Proven Clearwater Waterproofing and Drainage Solutions
Foundation Masters developed Florida’s first true engineered waterproofing system to solve these issues. Our process includes:
- Excavating a trench ~12″ below the slab edge to expose the footer and wall
- Applying the Seal Tight Waterproofing System to protect below-grade concrete and footings
- Designing engineered drainage piping or sump discharge to safely redirect water away from the structure and underlying soils
- Installing gutters and grading corrections to control surface runoff
This stops moisture intrusion, prevents soil erosion, and helps reduce sinkhole risk under Clearwater properties.

Frequently Asked Questions — Clearwater Drainage & Waterproofing
Because Clearwater averages 50–60 inches of rain per year and sits on a water table just 2–6 ft below grade, flooding and slab moisture are common. These expert answers explain why it happens and how engineer-designed drainage and waterproofing protect your home or building long-term.
Q1. Why does my yard flood even though drains are installed?
Clearwater’s flat coastal terrain (slopes <1%) and shallow water table — often only 2–4 ft down after storms — mean gravity drains can back up when soils are already saturated. During summer storms dropping 3 inches/hour, drains simply can’t outflow because the groundwater is nearly at surface level. Our systems add engineered sump discharge and deep French drains that keep working even when the natural table rises.
Q2. Why is my slab letting moisture through?
Many older Clearwater homes were built at or near grade with 6-mil vapor barriers that degrade after 20–30 years. When storms raise the water table to within 2–3 ft of the slab, hydrostatic pressure forces water through concrete pores. Our Seal Tight System adds below-grade membranes and drains to resist up to 350 psf lateral water pressure.
Q3. Can you waterproof an existing home in Clearwater?
Yes. We excavate about 12 inches below slab edge, coat footers/walls with the Seal Tight waterproofing membrane rated to 60 ft hydrostatic head, and add 4-in perforated drains with sump pumps sized 40–80 gpm if needed. These retrofits stop moisture and protect foundations even in high water table zones.
Q4. Does tidal water really affect my property?
Absolutely. High tides and coastal surge can push saltwater 1–2 miles inland, temporarily raising groundwater by 12–18 inches. Properly engineered drains and sealed slabs decouple the foundation from these fluctuations and route water to safe discharge points.
Q5. Do you handle commercial parking lot drainage problems?
Yes. We rebuild catch basins, replace 6–12 in storm piping, and stabilize subgrades with flowable fill or grout for retail centers, HOAs, and industrial parks. Our retrofits typically increase surface drainage capacity by 30–50 %.
Q6. Where can I check my property’s flood risk?
Use FEMA’s Flood Map Service Center or the Pinellas County Flood Information Portal for updated flood zones and base flood elevations.
