Exterior Basement Waterproofing Experts in West Des Moines
BAM has served Polk County homeowners since 2012, delivering exterior basement waterproofing tailored to West Des Moines soil and weather. Our team understands Iowa's clay soils and seasonal freeze‑thaw cycles that drive water into foundations. We combine proven exterior membranes, perimeter drainage and foundation repairs to stop water at the source. All exterior work is backed by BAM's lifetime warranty for lasting peace of mind.
How BAM Fixes Exterior Waterproofing in West Des Moines
Our exterior waterproofing process begins with a full site and foundation inspection specific to West Des Moines properties, including grading and drainage review. We excavate to the footing, repair any foundation cracks, and install a high‑performance waterproof membrane and drainage board. A new perimeter drain is installed and tied to a sump or approved discharge, then we backfill with free‑draining stone and restore final grade away from the home. We coordinate with local codes and minimize disruption so your yard and landscaping are returned to neat condition.
West Des Moines homeowners need exterior solutions because Polk County's clay soils expand and contract and heavy spring rains and freeze‑thaw cycles increase hydrostatic pressure on foundations. Exterior waterproofing prevents water infiltration, reduces mold risk, and protects structural integrity over time.

Frequently Asked Questions — Exterior Basement Waterproofing in West Des Moines, Iowa
Many West Des Moines homes benefit from exterior waterproofing because Polk County's clay soils and variable rainfall can drive water toward foundations. If you have recurring dampness, visible damage to exterior grade, or older drainage systems, an exterior solution often prevents long‑term issues.
After a thorough inspection we schedule excavation, membrane and drain installation; most standard homes are completed in 2–5 business days depending on size and weather. Larger projects or jobs requiring permits or extensive foundation repair may take longer; your free estimate will include a detailed timeline.
Costs vary by home size, depth of excavation and necessary foundation repairs, so we provide a no‑obligation written estimate after inspection. All BAM exterior waterproofing installations come with a lifetime warranty to protect your investment and ensure lasting performance.
Look for persistent damp walls, efflorescence, mold or mildew, water stains near the floor, or standing water near the foundation after storms. In Iowa's clay soils, recurring hairline cracks and basement humidity that returns after interior fixes are strong indicators you need an exterior approach.
