For a typical basement, our WaterGuard® system is the ideal choice for waterproofing. This interior drain is designed to be installed below the floor slab, resting on top of the foundation footing. This keeps the drainage system out of the "mud zone", where drains can clog. WaterGuard® is installed with minimal invasion of the slab, and all concrete is restored after installation.
The WaterGuard® system collects water that seeps through basement walls and drains it to your sump pump. The system installs quickly and has a clean finished appearance, meaning you don't have to worry about having an unsightly drain around the basement. WaterGuard® works for both block walls and poured concrete, ensuring that your basement remains dry in all situations. This product also comes with a written lifetime warranty.
Sometimes the concrete floor in a basement is too thin for a drain to be installed on top of the footer. If we did install it on top of the footer, the drain would stick up past the concrete slab. We usually address this challenge with our FlowGuard® Thin Floor System. This system is designed to sit in front of the footing in a bed of drainage stone. After installation, the concrete floor is restored over the drain.
Like our other drain systems, FlowGuard® includes a wall flange, which extends up the wall to direct any leaking water to your sump pump system. This system avoids the "mud zone" to prevent any clogging issues as well. With quick installation and a seamless finish, you'll be able to enjoy protection from leaks in your basement for years to come.
If iron bacteria is present in your water, it will create a gelatinous, rust-colored substance known as iron ochre. This unpleasant material is notorious for smelling terrible, staining everything it touches, and clogging drainage systems. Our experts tackle this rare problem with our WaterGuard® IOS Basement Drain.
This product is a modified version of our WaterGuard® system that includes an extra-wide drain channel and larger drainage openings. To allow for easy drain system maintenance if clogged, the drain system also includes an exposed, removable lid. This system will protect your home from the nasty appearance and smell iron ochre brings while helping prevent any water from seeping into your basement.
For many homeowners, preventing flooding from an outer entryway such as a hatchway, garage door, or doorway is a priority. In this case we use the TrenchDrain™ Grated Draining Pipe to span the opening and prevent water from flowing into your basement. The grated opening of this system is designed to accept water from the floor, where it's then redirected to your perimeter drain and your sump pump.
This system comes with a removable lid to clear any debris that may enter the drain and is compatible with all our perimeter drain systems. The device lays smoothly across the floor to eliminate tripping hazards. We also recommend installing the drain inside the door to prevent debris from flooding in as well as to prevent freezing in the winter. TrenchDrain™ comes with a written lifetime warranty.
Unfortunately, trench drains have the unintended consequence of allowing air from drainage channels and from the ground into the home. This air from the ground may contain hazardous radon gas, a naturally occurring radioactive gas. TrenchLock™ trench drain inserts are specially designed to block unwanted ground air and gasses from entering the basement and ultimately your home.
TrenchLock™ is an insert that can be installed in an existing trench drain to allow water down without allowing air to come up. The system comes with balls that fit over the drainage holes, which create an airtight seal when there is no water. When water enters the drain, the ball floats to allow the water to drain, sinking back into place as the water drains out. This allows the drain to function perfectly without allowing air to enter.
