Helical pier foundations and screened deck systems for Pipestone Lake retreats
WTS II Contracting is a licensed Michigan residential builder specializing in custom deck construction throughout Eau Claire, utilizing helical pier foundation systems that penetrate organic muck and peat soil near Pipestone Lake and Indian Lake to reach stable bearing strata, eliminating the settling and sinking that destroys decks built on standard concrete footings, with comprehensive expertise in Village of Eau Claire, Pipestone Township, and Berrien Township zoning setback requirements and EGLE wetland permit coordination for waterfront construction. Our inland lake retreat approach—featuring screened porch integration systems that combat mosquito pressure in wooded lots, structural beam sizing capable of supporting future roof conversions, and above-grade post mounting that prevents rot in saturated organic soil—creates durable outdoor spaces engineered specifically for Eau Claire's unique inland water and forested environment.

Pipestone Lake, Indian Lake, and other Eau Claire inland waters are surrounded by organic soil composed of decomposed vegetation, peat, and muck that compresses under load like a sponge, causing standard concrete footings to sink 2-6 inches over 5-15 years. This isn't sand or clay—it's partially decomposed organic material with almost no structural bearing capacity.
The inland lake soil composition:
The standard concrete footing failure sequence on lakefront organic soil:
We've measured settlement on Pipestone Lake decks ranging from 2 inches (annoying but functional) to 8 inches (catastrophic—deck pulled completely away from house). The repair cost: $15,000-30,000 for complete rebuilding with proper foundations.
The organic soil problem is invisible during construction: Footings look fine when poured, inspector approves them, deck is built to code. But the soil compresses slowly over years—homeowner doesn't notice until significant damage has occurred. By the time you see the problem, it's too late for prevention.
WTS II Contracting uses helical pier foundation systems on all Eau Claire lakefront properties with organic soil:

Cost Analysis:
For Eau Claire lakefront properties with organic soil conditions, helical piers aren't an upgrade or luxury option—they're the only foundation system that prevents catastrophic settlement.
Unlike Lake Michigan properties where constant wind keeps flying insects at bay, Eau Claire's inland lakes and dense forests create protected, humid environments with extreme mosquito populations that make unscreened decks unusable during prime outdoor season (May-September).
The inland lake mosquito problem:
Homeowners describe mosquito pressure as "unbearable"—unable to use deck for more than 5-10 minutes before being driven inside. This renders the deck investment essentially worthless during the entire outdoor season.
WTS II Contracting designs deck structures specifically to accommodate screened porch integration:

Cost Comparison:
For a 12x16 foot deck (192 sq ft), building proper structure from the start adds approximately $600-1,200. Installing screening immediately costs $5,700-8,500 more than open deck. But it transforms the space from "rarely used due to mosquitoes" to "primary outdoor living area used daily May through September"—easily justifying the investment for Eau Claire wooded properties.
Many Eau Claire lakefront properties include regulated wetlands—areas where soil is saturated for significant portions of the growing season, supporting wetland vegetation. Building any structure (including decks) within or adjacent to regulated wetlands requires permits from Michigan Department of Environment, Great Lakes, and Energy (EGLE) in addition to local building permits.
The regulatory framework:
The problem: homeowners and contractors often don't realize wetlands are present until after construction begins. EGLE enforcement discovers violation, issues stop-work order, requires restoration and proper permitting—$8,000-20,000 in additional costs plus project delays of 3-6 months.
WTS II Contracting performs wetland evaluation during initial site visit:

Permit Timeline:
WTS II Contracting manages entire EGLE permit process—homeowner doesn't deal with environmental compliance complexity. We submit applications, coordinate with EGLE reviewers, design mitigation measures if required, and ensure full regulatory compliance before breaking ground.
Eau Claire has one of the most confusing jurisdictional situations in Berrien County: Village of Eau Claire, Pipestone Township, and Berrien Township all serve areas with "Eau Claire" mailing addresses. Homeowners regularly apply for permits at the wrong office, wasting weeks and discovering the error only after being told their paperwork is invalid.
The three jurisdictions:
All three have different:
The costly mistake: Homeowner assumes they're in Village because address says "Eau Claire," pulls permit at Village Hall. Construction begins. Township inspector drives by, issues stop-work order—wrong jurisdiction. Must shut down project, apply to correct township office, wait 2-3 weeks for new permits, possibly modify design to meet different setbacks. Lost time: 3-4 weeks. Extra costs: $500-1,500 in permit fees and modified plans.
WTS II Contracting verifies jurisdiction before any design work:
The traditional method of setting posts—dig hole, place post in hole, backfill with soil or concrete—works adequately in dry mineral soil. But in Eau Claire's saturated organic soil near inland lakes, burying pressure-treated posts guarantees rot failure within 8-12 years even with .60 retention ground-contact rated lumber.
The post-rot failure mechanism:
The problem is hidden until failure: post looks fine above grade. All the rot is underground where you can't see it. First indication of problem is usually sudden collapse during heavy snow load or when deck is crowded with people.
WTS II Contracting uses above-grade post mounting that keeps timber out of saturated soil:
Method 1: Concrete Piers with Post Bases (Standard Soil)
Method 2: Helical Piers with Brackets (Organic Soil)
Method 3: Elevated Deck-on-Posts (Extreme Conditions)
Above-grade mounting adds approximately $40-60 per post in hardware costs compared to burying posts. But it extends post lifespan from 8-12 years to 30-50+ years—the difference between needing complete deck rebuilding versus minor maintenance.
Rural Eau Claire properties often feature long deck spans designed to preserve views over wooded lots or toward lakes—minimizing posts that interrupt sightlines. DIY builders and budget contractors undersize beams for these spans, creating decks that flex and bounce noticeably when walked on.
The beam-sizing failure:
The issue is building codes specify structural minimums for safety—beams won't collapse—but don't address user comfort or perception of quality. A deck can be "code compliant" and still feel like a trampoline.
WTS II Contracting calculates beam sizing for rock-solid feel, not just code minimum:
Triple Beam Construction:
LVL (Laminated Veneer Lumber) Beams:
Post Placement Strategy:
For typical 20x12 foot deck with 16-foot beam spans, upgrading from double 2x10 (code minimum) to triple 2x10 beams adds approximately $400-600. But it transforms the deck from "bouncy and concerning" to "solid and high-quality"—directly impacting how the space feels and property value perception.
We use contractor-grade materials specifically engineered for shaded, humid inland lake environments:
Yes—zoning setback requirements still apply even if the deck isn't attached to the house, and structures over 200 square feet typically require building permits regardless of attachment method. The term "floating deck" refers to a deck that rests on concrete blocks or footings at grade level rather than being attached to a house with a ledger board—essentially a freestanding platform. However, Pipestone Township (and most Michigan jurisdictions) regulate these structures through both zoning ordinances and building codes: (1) Setback requirements—floating decks must maintain minimum distances from property lines (typically 5-10 feet) and from water bodies if lakefront property (25-50 feet from ordinary high water mark). Building too close to property line results in zoning violation requiring removal or variance. (2) Building permit requirements—structures over 200 square feet or over 30 inches high require permits with inspections verifying frost-depth footings (42 inches), proper framing, and code-compliant railings. (3) EGLE permits—if floating deck is near wetlands or within regulated distance of inland lake, state environmental permits may be required in addition to township approval. The mistake: homeowners assume "floating" means "exempt from regulations"—build without permits, discovered during home sale inspection, must retroactively permit (expensive) or remove. WTS II Contracting pulls all required permits for floating decks and ensures zoning compliance from design phase.
No, you cannot place structural footings or permanent supports over a septic tank or drain field—but we can cantilever deck joists over the tank access area if structural footings are placed safely outside the septic system zone. Michigan Plumbing Code and local health departments prohibit building structures over septic systems for critical reasons: (1) Tank access requirements—septic tanks must be accessible for pumping every 3-5 years. Standard 24-inch diameter tank lids must be exposed or have removable deck hatches. Building permanent structure over tank prevents maintenance. (2) Drain field protection—concentrated loads (footings, posts) compact soil in drain field, crushing perforated pipes and destroying the system's ability to treat wastewater. Replacement cost: $8,000-25,000. (3) Soil compaction—even distributed loads can compact drain field soil, reducing infiltration capacity. WTS II Contracting's approach for decks near septic systems: (1) Locate septic components—obtain system as-built or use probe to find tank and field lines, (2) Position footings outside septic areas—maintain 10-foot minimum clearance from drain field, 5-foot from tank, (3) Cantilever joists over tank—extend joists beyond beam to span over tank access without footings. Cantilever limited to 1/4 of joist span (3 feet for 12-foot span), (4) Install deck hatch—removable deck section over tank access for pumping. This design allows deck to extend near septic areas without damaging system or violating code.
PVC-capped composite prevents the algae and moss growth that makes wood decks slippery and dangerous in shaded, humid conditions common on Eau Claire's wooded lakefront properties. The shaded-lot challenge: dense tree canopy blocks sunlight and maintains high humidity year-round—creating perfect conditions for Gloeocapsa magma (black algae), moss, and mildew growth on deck surfaces. Pressure-treated wood problems in shade: (1) Algae colonization—green/black slime appears on boards within 2-3 years, (2) Slippery when wet—morning dew or rain makes algae-covered boards dangerously slick, (3) Accelerated rot—boards never fully dry between rain events, (4) Annual cleaning required—pressure washing and biocide application every spring, (5) Splintering—moisture cycling causes rapid wood fiber separation. WTS II Contracting recommends PVC-capped composite for all shaded Eau Claire properties: Premium options include Trex Transcend or TimberTech AZEK—hard acrylic cap layer resists organic growth. How it works: (1) Non-porous surface—algae spores cannot penetrate cap layer or establish root structure, (2) No nutrients—synthetic material provides nothing for organisms to feed on, (3) Easy cleaning—garden hose rinse removes surface spores before colonization, (4) Anti-microbial additives—some brands include zinc oxide or copper compounds that actively inhibit microbial growth. Result: decks in deep shade stay clean with minimal maintenance—garden hose rinse 2-3 times per year versus weekly pressure washing for wood. Budget option: TimberTech Prime+ offers mold-resistant capped composite at lower price point than Transcend/AZEK.
