Water Control That Stops Property Damage
Drainage Solutions in Candia for wet yards, foundation water issues, and erosion prevention
Water pooling near foundations, washing out landscaping, or creating muddy areas in the yard indicates that surface runoff isn't moving off the property correctly. These patterns develop when grading slopes toward structures instead of away, when downspouts discharge too close to the house, or when natural drainage paths are blocked by fill or construction. Grimard's Property & Excavation LLC installs drainage solutions in Candia that redirect water through French drains, adjust grading to improve flow, and prevent the erosion and foundation damage that result from uncontrolled runoff.
Drainage work begins with identifying where water enters the property, where it collects, and where it needs to discharge, then installing subsurface drains or regrading surfaces to establish positive flow away from structures. The approach depends on soil permeability, slope limitations, and whether water can be directed to existing swales, culverts, or natural drainage courses.
Request a drainage assessment to identify water flow problems and determine which solutions will resolve them.
French drains are installed by excavating trenches along problem areas, lining them with fabric to prevent soil infiltration, and filling them with stone surrounding a perforated pipe that collects groundwater and channels it to a discharge point downslope. Grading adjustments involve reshaping the soil surface to create consistent slopes, typically two percent or more, that move water predictably rather than allowing it to pond in depressions or flow toward basements.
After drainage improvements are complete, water will flow away from the foundation during rainstorms instead of pooling against basement walls, and previously saturated areas of the yard will dry out enough to support grass and landscaping. Erosion patterns where soil washes into gullies will stabilize, and you won't see standing water lingering for days after storms the way it did before drainage paths were corrected.
Some properties require multiple drainage strategies, combining subsurface drains in areas with high groundwater, surface grading to redirect roof runoff, and outlet systems that prevent water from re-entering the property from neighboring land. Solutions are tailored to the specific failure points observed on the property rather than applying generic fixes that don't address the actual flow problem.
Questions Before Starting Your Project
Drainage solutions vary based on water volume, soil conditions, and where discharge is possible given the property layout.
What causes water to pool near foundations?
Pooling occurs when soil slopes toward the house rather than away, when gutters discharge directly at the foundation, or when compacted soil from construction prevents water from infiltrating and forces it to run along the surface.
How does a French drain differ from surface grading?
French drains capture subsurface water and groundwater before it reaches problem areas, while surface grading redirects water that flows across the ground, with both often needed to fully resolve drainage issues.
Where does collected water discharge?
Discharge points include daylight outlets at the property edge where water can flow to lower ground, connections to existing storm drains where permitted, or dry wells in areas where soil infiltration rates are high enough to handle the volume.
When is regrading necessary instead of just installing drains?
Regrading is required when the surface itself slopes incorrectly or when low spots collect water that subsurface drains alone won't eliminate, particularly near foundations where positive slope away from the building is critical.
