Drainage

When previously undeveloped land becomes developed, the ground that soaked up rainwater is replaced with roads, driveways and structures. As a result, rainwater runoff is no longer naturally collected which can collect and cause erosion or other damage. Solid Foundation utilizes several methods of water management to control erosion and runoff including swales, retaining walls, and ponds. The goal of water management is to properly drain rainwater to nearby streams, replicating the way in which the water would be naturally dispersed.

If runoff is not properly collected and drained, there are a number of negative consequences including:

  • Water Contamination
  • Debris that can clog storm drains causing flooding
  • Increase volumes of stormwater resulting in erosion
  • Pollutants distributed that can affect wildlife and the quality of water

To mitigate these issues you must convey any water away from your house using one of two controlled methods:

Retaining Walls

block retaining wall reinforced with poured concrete and rebar

Designed and constructed to resist the pressure of soil when there is a desired change in ground elevation that exceeds the soil’s angle of repose, retaining walls are used in areas of land possessing undesirable slopes or in areas where the landscape needs to be shaped and engineered for a specific purpose. Most retaining walls are cantilever retaining walls, which are freestanding structures without lateral support at the top. The walls must resist the lateral pressures generated by loose soil and water, so is important to have proper drainage behind the wall in order to limit the pressure to the wall's design value. Drainage materials will reduce or eliminate the hydrostatic pressure and improve the stability of the material behind the wall. We design and construct retaining walls to ensure stability against overturning, sliding, excessive foundation pressure and water uplift.

Perimeter Drainage Pipes

The scope of a simple project is to install an area drain, dig a trench and lay PVC piping in that trench. The piping will be connected to a pop-up emitter which will help disperse the water away for the residence and send it to the storm water system. Foundation drains will divert water away from the foundation while roof drainpipes and gutters remove water from the top of the home. These all should lead to storm drainpipes which collect rainwater into the city’s storm water system. 

Common components of storm water systems include:

  • Catch basins – used for downspouts and low landscape locations
  • Channels – used for hardscapes
  • Flo-wells – used for subsurface drainage
  • Pop-up emitters – discharges excess water
