Seattle Rockeries' plans include solutions for draining foundations, paved surfaces, water traps, and gutter downspouts. Geotechnical engineers and landscape drainage professionals diagnose your water table, terrain, and soil compositions. Signs of drainage issues include standing water, soggy grass, bare roots, dead grass, mosquitoes, and other swamp creatures. Create a drainage plan to fix dangerous soil saturation levels on your property that affect the health and well being of your family.

Drainage problems destroy the property value of Seattle homes every day. When water collects around structures it destroys interior finishes, drywall, wood flooring, and contributes to foundation failure. Heavy rain and flooding around your foundation can cause soil erosion and landslides.

Channel drains are a prefabricated linear drainage solution that can be installed on a driveway, patio, pool deck, garden, walkway, parking lot, or garage. Channel drains collect and remove runoff over large areas and operate like a gutter for paved surfaces. Channel drains are made from metal, plastic, or polypropylene and often feature a grate cover that can be removed for cleaning.

Channel drains come in three load recommendations:

  • Class A is used for pedestrian and bicycle traffic.
  • Class B is used for car and light truck traffic.
  • Class C is used for delivery truck and tractor traffic

Water channel drains are installed by digging a trench to fit your installation. Seattle Rockeries offers a variety of sizes and shapes including slim and mini channels. The channel drain is fitted into the ditch and filled in with concrete or a paver.

Curtain drains are shallow trenches filled with crushed rock, gravel, or natural stone. Curtain drains are similar to French drains but offer a smaller scale for specific tasks such as diverting water away from a driveway, patio or foundation. While French drains often deal with groundwater, curtain drains are built to capture and divert surface water. Curtain drains are often built around the basement area of a home to prevent surface water from collecting near a foundation.

Dry wells are underground structures that collect, percolate / dissipate, and remove stormwater from your property. Dry wells often receive runoff from french drains, channel drains, downspout extensions, curtain drains, and trench drains. Dry wells are passive structures that allow collected greywater to flow through a series of distributed holes into the water table below.

Gutter downspout extensions are standard in Seattle Rockeries drainage plans and are included in our emergency drainage solutions. During Seattle rain downspouts divert gutter water away from foundations, landscapes, and gardens. Seattle Rockeries uses flexible, rigid, low profile, and custom downspout extensions to fit your environment. Gutter downspout extensions are used to fix standing water near gutter drains which deteriorate foundations and homes in the Puget Sound. Downspout extensions lead directly into underground pipes to offer seamless drainage from roof to stormwater system.
