Improper Grading & Drainage
Water is one of a home’s greatest threats. When a lot is graded incorrectly or the drainage system is poorly designed, every rainfall can push water toward the foundation instead of away from it. Over time, that water saturates the soil, seeps into crawl spaces and basements, and causes movement, cracking, and mold. What should have been a simple landscaping or site-prep issue can turn into a major structural and health concern.
How Grading and Drainage Affect a Home
Proper grading means the ground slopes gently away from the house so that water runs off naturally. Building codes and engineering standards require a minimum slope to ensure that surface water doesn’t collect around foundations, patios, or retaining walls. When builders ignore these standards—by leveling lots too flat, compacting fill unevenly, or adding landscaping that changes the slope—they create a situation where water has nowhere to go but down and in.
In new developments across Colorado, this problem often shows up within the first year. Homeowners notice pooling water after rainstorms, soggy soil near the foundation, or damp spots in basements. As the moisture cycles through freeze-thaw seasons, it weakens the surrounding soils and begins to undermine the home’s structural support.
Common Signs of Improper Grading or Drainage
Water pooling next to the home or under decks and patios
Damp or musty basements and crawl spaces
Cracking or flaking foundation walls
Soil erosion near downspouts or retaining walls
Standing water long after a rainstorm
Foundation or slab settlement near exterior walls
Even seemingly minor drainage issues can accelerate foundation movement or cause lateral pressure against basement walls. Addressing the problem early can prevent more expensive repairs later.
Why These Problems Occur
In many cases, grading and drainage problems arise because the builder did not properly compact fill material or failed to install adequate surface swales and downspout extensions. Sometimes the grading plan approved by the municipality was never followed on site. Other times, a homeowner’s property is affected by runoff from an adjacent lot because the developer failed to coordinate elevations across multiple parcels. These are not simple maintenance issues—they are preventable construction errors that violate accepted engineering and building standards.
Who Is Responsible
Under Colorado law, contractors, developers, and engineers are required to design and construct improvements in a manner that protects property from water damage. When improper grading, insufficient drainage, or missing waterproofing results in property damage, the responsible construction professionals can be held liable under the Colorado Construction Defect Action Reform Act (CDARA). These cases often overlap with claims for foundation movement, waterproofing failures, and soil instability.
How Hollington Law Firm Can Help
At Hollington Law Firm, we represent Colorado homeowners dealing with grading and drainage failures that lead to water damage and structural distress. We work with independent civil and geotechnical engineers to evaluate the grading plan, measure slopes, and determine whether the builder followed approved designs. Once the cause is identified, we pursue recovery through the CDARA process, seeking funds for proper re-grading, drainage correction, and any necessary structural or waterproofing repairs.
We understand that homeowners often face pushback from builders who claim that “settling” or “landscaping changes” caused the problem. Our job is to separate normal wear from negligent construction and to make sure the responsible parties—not the homeowner—pay for the fix.
