What waterproofing work covers

Waterproofing in the Denver metro usually means below-grade work: exterior membrane and drainage after excavation, or interior drain tile and a sump. Grading and downspout discharge matter as much as the membrane. This is not roofing. A municipally licensed Denver general contractor coordinates the project and licensed specialty trades. Cost is project-specific and depends on interior versus exterior access, depth, and groundwater.

text

Excavation, groundwater, and floodplain

Exterior work is an excavation. Denver DOTI reviews Sewer Use and Drainage (SUDP) for excavations, storm grading, floodplain, and groundwater. Groundwater dewatering has its own SUDP path. Check floodplain status at denvergov.org/flood before drawing. If the work includes underpinning, a basement dig-out, or foundation repair beyond IRC prescriptive limits, City and County of Denver Community Planning and Development requires structural drawings and calculations (DBCA 133.2).

text

Permits and who coordinates the work

CPD building permits apply when structure or occupancy is affected. DOTI SUDP applies to the excavation and drainage. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades for waterproofing scopes.

What buyers should prepare

Where water enters, interior versus exterior access, existing sump yes or no, and neighboring foundation proximity.

FAQ

Common questions

Does foundation waterproofing need a Denver permit?

Exterior excavation typically needs SUDP and often a building permit. Interior drain tile may still need permits if plumbing or structure changes.

Who handles waterproofing permits and licensing?

A municipally licensed Denver general contractor coordinates the project and licensed specialty trades. Colorado has no statewide general contractor license.

Interior drain or exterior membrane?

Exterior treats the wall from outside when there is room to excavate. Interior drain tile collects water that already reaches the slab. Site conditions decide.

When is structural review required?

When underpinning, basement dig-outs, or foundation repair go beyond IRC prescriptive limits. CPD asks for sealed drawings and calculations.

What information helps define scope?

Water-entry photos, floodplain status, lot-line clearance, and city or county.
