Protect Your Patio and Property From Water Damage

Water is the number one cause of failure in outdoor hardscape installations. Without proper drainage planning, rainwater and runoff can pool on patios, erode surrounding landscaping, and even damage your home’s foundation.

The FLOWGUARD™ Water Management System is Mezzacappa Concrete’s engineered approach to controlling and redirecting water away from patios, driveways, and outdoor living areas.

By managing water properly beneath the surface, FLOWGUARD™ helps ensure that your patio or hardscape project performs exactly as it should for years to come.

Why Proper Patio Drainage Matters

Many outdoor spaces fail because drainage was not properly considered during construction. Poor drainage can lead to costly structural and aesthetic problems over time.

Common issues caused by improper drainage include:

Installing a properly designed drainage system protects both the beauty and structural integrity of your outdoor living space.

How the FLOWGUARD™ System Works

Every property has different drainage challenges based on grading, soil conditions, and surrounding structures.

The FLOWGUARD™ system begins with a detailed evaluation of how water moves across the property and where it needs to be redirected.

FLOWGUARD™ systems are commonly installed beneath:

  • Paver patios
  • Concrete patios
  • Outdoor living spaces
  • Driveways and walkways
  • Pool decks and landscape areas

By integrating drainage into the initial construction process, we ensure that water never becomes a long-term problem for the property.

Components of the FLOWGUARD™ Drainage System

Each installation is customized based on the specific needs of the property. Depending on the project, a FLOWGUARD™ system may include several drainage components working together.

  • Custom Grading and Runoff Planning

    Proper grading is the first step in managing water flow. Surfaces are carefully pitched to guide runoff away from structures and toward drainage collection points.

  • Channel Drain Systems

    Linear channel drains are commonly installed along patio edges or transitions between surfaces to capture surface water before it spreads across the patio.


    These systems are especially effective for patios located near the house where water must be redirected quickly.

  • Underground Drainage Piping

    Drainage pipes installed beneath the surface transport collected water away from the patio area and toward a safe discharge location.


    Both solid and perforated piping systems may be used depending on the drainage strategy.

  • Catch Basins and Cleanouts

    Catch basins collect water from drains and direct it into underground piping. Cleanout access points allow the system to be inspected and maintained if necessary.

  • Downspout Integration

    Roof runoff from downspouts can often be integrated into the patio drainage system, preventing concentrated water from damaging surrounding areas.

  • Dry Well Systems

    In some properties, dry wells are installed underground to allow water to slowly disperse into surrounding soil instead of flowing toward neighboring areas.

  • Precision Backfill and Compaction

    Proper backfilling and compaction ensure that the drainage system remains stable beneath the patio surface and continues performing effectively over time.

Where FLOWGUARD™ Is Most Important

While every patio benefits from drainage planning, certain properties require advanced water management solutions.

FLOWGUARD™ systems are particularly valuable for:

  • Homes with limited yard drainage space
  • Properties with close neighboring structures
  • Backyards located near foundations or basements
  • Patios built against homes or retaining walls
  • Areas prone to heavy rainfall or water runoff

By installing the proper drainage system during construction, homeowners avoid expensive drainage corrections later.

Designed to Protect Your Hardscape Investment

A professionally installed patio is a significant investment in your home.

Without proper drainage planning, even high-quality materials like pavers, stone, or concrete can experience premature wear.

The FLOWGUARD™ system protects your investment by ensuring water is properly managed beneath the surface.

This approach helps extend the lifespan of your patio while maintaining a clean, functional outdoor living environment.
