About Kek Dredging
A Pennsylvania-based team focused on sediment management, waterway health and thoughtful, site-specific planning.
Rooted in Chester County, Focused on Waterways Across the Region
Kek Dredging was formed around a straightforward observation: many pond owners, homeowners' associations, municipal staff and land managers in Southeastern Pennsylvania have limited access to clear, honest information about what sediment build-up actually means for their property and what realistic paths forward look like. Rather than treating dredging as a generic commodity service, we treat it as a technical discipline that deserves careful evaluation, patient explanation and a willingness to say when a smaller intervention — or no intervention at all — is the right call for a given site.
Operating from our office at 991 Fox Chase Dr in West Chester, Pennsylvania, we are positioned within easy reach of Chester County's dense network of ponds, tributaries and stormwater management features, as well as the broader watersheds that extend across the Mid-Atlantic. That geography matters: the region's mix of suburban development, agricultural land and forested headwaters creates a wide variety of sediment sources, from construction runoff to leaf litter to streambank erosion, and each combination calls for its own read of the situation.
We built our process around field observation first. Aerial photographs and historical records can suggest where sediment has accumulated, but walking a shoreline, probing depths, and talking with the people who use a pond or waterway every day consistently reveals details that remote assessment misses. That fieldwork-first habit shapes how we talk with clients, how we frame recommendations, and how we describe the trade-offs between different dredging and restoration approaches.
Milestones in Our Approach
Rather than a simple company timeline, these are the stages that describe how our process and perspective have matured.
Learning the Region, One Site at a Time
Our earliest work centered on smaller pond and drainage assessments across Chester County, which gave us a close, ground-level understanding of how local soils, storm patterns and land use combine to drive sedimentation.
Building a Consistent Evaluation Framework
As the range of projects we were asked to weigh in on grew, we developed a more consistent framework for site evaluation — covering depth surveys, sediment characterization, access planning and coordination with permitting requirements.
Extending Into the Broader Mid-Atlantic
With a dependable process in place, we began supporting projects further from home base, applying the same fieldwork-first habits to lakes, stormwater basins and stream reaches across the wider Mid-Atlantic region.
A Steady, Considered Presence
Today, Kek Dredging continues to focus on measured, well-communicated guidance rather than one-size-fits-all solutions, with Karl Lange overseeing each engagement from initial site conversation through final documentation.

Principles That Guide Every Engagement
Safety First, Always
Field conditions around water are unpredictable. Every site visit begins with a review of access, terrain and equipment safety considerations.
Environmental Stewardship
We factor downstream water quality, aquatic habitat and erosion risk into every recommendation, not just the immediate task at hand.
Precision & Reliability
Depth surveys, sediment sampling and site documentation are handled carefully so that plans are based on accurate, current information.
Transparent Communication
We aim to explain findings and options in plain language, including the limitations of any given approach, so clients can make informed decisions.
Where We Work
Our home base in West Chester places us at the center of Chester County, but our field experience extends well beyond it. We regularly discuss projects across the Philadelphia suburbs, the Brandywine and Schuylkill watersheds, and neighboring counties throughout Southeastern Pennsylvania, and we remain open to conversations about sites elsewhere in the Mid-Atlantic region depending on scope and logistics.
Because so much of dredging planning depends on local hydrology, soil type and regulatory context, we find it useful to stay close to the areas we know best while remaining flexible enough to support clients with unique or out-of-area sites who need an informed second opinion.
